This thesis gives a detailed picture of how planners, politicians, residents and transport engineers in three societies, Britain, Germany and the United States reacted to one of the most powerful inventions of the late nineteenth century, the motor car. Misjudgments of the potential growth of motor vehicle ownership and its adverse effects had serious repercussions in the coming decades, primarily in the dense urban areas. Disturbing has been the underestimation of the importance of public transport as a real alternative to the motor car in urban areas, first by the United States and even several decades later by Britain. Of the three countries, only Germany seems to have struck a better balance. Not surprisingly, already at the beginning of the twentieth century, conflicts occurred between the weaker road participants (pedestrians and cyclists), the existing urban fabric and the motor vehicle. A more comprehensive comparison between Britain and Germany shows that both countries developed specific patterns and had different attitudes towards road transport. Far more has been invested and planned in Germany whereas Britain has shown not so much a lack of foresight in planning but 'in investment in road transport. This major difference has had very visible effects an today's urban structure and transport situation. The demand for restraint of motor traffic had different motives in the two countries, and is not such a new idea as is often assumed. While in Germany even in the 1920s and 30s the protection of historic inheritance was a decisive motive, in Britain that was not the case. Questions of traffic restraint were however raised in connection with road safety and later in the 60s as a means of improving the urban environment. The turning point of nearly unlimited promotion of car use in urban areas took place in Germany during the 60s and 70s, whereas the Buchanan Report had already warned in the early 60s against the adverse effects cars could have in urban areas if they were not controlled. Although even in Britain the report was misunderstood and largely not put into practice, the wave of protest against road building occurred earlier there than in Germany. As a whole, Britain has shown a brillance of ideas in restraining motor vehicles which was lacking in the Federal Republic. At the beginning of the 70s, discussions started seriously in Germany an traffic calming concepts which were slowly transformed into reality, Britain seems to have followed these examples, but with a considerable time lag.
With the present brake signal pattern the traffic behind only receives the information that the brakes are applied, however, the drivers have no information about the intensity of the braking maneuver. In this report it is examined on the basis of a study of the literature, how the rear signal pattern could be optimized for a special representation of emergency braking maneuvers. In principle there are two suitable possibilities to reduce the driver reaction time: - An increase in the area and luminance of the brake lights intuitively provide the drivers following with an impression of approaching the vehicle in front , - Flashing lights are particularly suited to attract the attention of the driver following to the deceleration of the vehicle ahead , - The following advancement is recommended as an optimization of the rear signal pattern: When the brake assistant or ABS actuates or at a vehicle deceleration rate greater than 7 m/s-², the emergency braking maneuver is signaled by flashing of the third high-mounted brake light at a rate of 3-5 Hz. As an option, the area and luminance of the two lower brake lights could be increased in addition. These measures require changes to ECE Regulations No. 7 and No. 48 as well as to the Vienna Convention. The purpose of the described solution is to reduce the number or severity of rear-end accidents.
Topics of this report are: Road construction (highways, interstate roads, urban by-passes, cycle tracks, construction sites, level crossings removal), traffic management systems, road tunnel equipment, harmonisation of vehicle regulations, accident statistics and accident research, passive vehicle safety, active vehicle safety , automotive environmental protection and rescue systems.
Data concerning accidents involving personal injury which have been collected in the context of in-depth investigations on scene in the Hannover area since 1973 and in the Dresden area since 1999 represent an important basis for empirical traffic safety research. At national and international level various analyses and comparisons are carried out on the basis of "in-depth data" from the above mentioned investigations. In-depth data play a decisive role e.g. within the validation of EuroNCAP results on secondary safety (crashworthiness) of individual passenger car models. Thus, statistically sound methods of data analysis and population parameter estimation are of high importance. Since the 1st of August 1984 the "in-depth investigations on scene" in the Hannover area have been carried out according to a sampling plan developed by HAUTZINGER in the context of a research project on behalf of BASt. In the meantime a second region of in-depth investigation on scene was added with surveys in Dresden and the surrounding area. Internationally, the acronym GIDAS (German In-Depth Accident Study) is commonly used for the two above mentioned surveys. The objective of a current research project (topic of this contribution) is, among other things, to examine and adjust the previous weighting and expansion method for the two regional accident investigations to the current general conditions.
In recent years considerable progress in active and passive safety of road vehicles has been made. The road traffic of today is much safer than in the past. A current vehicle has a lot more safety elements resulting in an improved inner and outer technique. In most European countries the number of fatalities is decreasing despite growing traffic and road usage. Nevertheless, the number of casualties in road traffic accidents is high enough, thus more progress is needed if the number of fatalities is to be reduced by 50%, as postulated by the European Commission for the year 2010. In order to develop countermeasures and further possibilities for injury prevention, it is increasingly important to have accident data available, supplying results quickly and giving the best overview across Europe. In-Depth-Data Sampling Procedures have a huge historical development, starting in the 60ies by the car manufactures, continued during the 70ies mostly by some universities mainly in England, Sweden, France and Germany, today a net of in-depth-investigation teams are working across Europe and around the world.One of the oldest teams is located at the Hannover Medical School, founded in 1973 by the German Government on behalf of the Federal Highway Research Institute Bast. It was the only team worldwide that was equipped with blue light emergency cars, working on scene in time so directly after the event and working continuously during the years, collecting 20 thousand accidents within 30 years period. Since 1999 the order is carried out in cooperation with the German car industry, which is interested and has benefit on the data too. On the basis of the new data collection, so called GIDAS (German In-Depth Accident Study), that has been run at the Technical University Dresden and the Medical University Hannover), a special tool for In-Depth-Accident Analysis was founded. It is the task of this conference to build a platform for such research based on In-Depth-Investigation. The conference is specially aimed at the area of accident data analysis in order to contribute to the harmonization of different investigation methods and accumulation of different results that does exist for different countries worldwide. Up to now no special conference did exist to deal with accident data only following in the discussion for an improvement in traffic and vehicle safety. ESAR - expert symposium on accident research - should be a step forward. This first international conference is being organized by the Accident Research Unit at the Medical University Hannover jointly with the German Federal Highway Research Institute Bast and the Research Association of German Car Manufacturers FAT. The conference should be a platform for an interdisciplinary exchange of information based on the different presentations from participants around the world.

The data situation for quantifying the proportion of accidents avoided by the introduction of active safety systems is incomplete, since there is generally no data available on the accidents avoided by the technology in question. In this paper, a split-register approach is suggested and compared with the classical case-control approach known from epidemiologic applications. Provided a set of assumptions hold, which can reasonably be made in such data situations, the split register approach allows inferences on the population accident risk. For both approaches the benefits of basing the analysis on the results of a logistic regression to adjust for confounding factors are outlined. The biasing effects of violating key assumptions are discussed and the split-register approach is demonstrated using the example of the active safety system ESP with data from the German in-depth accident study GIDAS.
This paper describes the methodology of In-Depth Investigation in Germany on the example of GIDAS (German In-Depth Accident Study). Since 1999 in Germany a joint project between FAT (Forschungsvereinigung Automobiltechnik or Automotive Industry Research Association) and BASt (Bundesanstalt für Straßenwesen or the Federal Road Research Institute) is being carried out in Hannover and Dresden. The methodology of this project is based on a statistically orientated procedure of data sampling (sampling plan, weighting factors). The paper describes the possibilities of such in-depth investigation on the results of the offered title. The accident cases were collected randomly within GIDAS at Hannover. There are more cases existing from previous investigation started in 1985 under the same methodology. The portion of rollovers can be established at 3.7% of all accidents with casualties in the year 2000. For the study 434 cases of car accidents with rollovers are used for a detail comprehensive analysis. The accidents happened in the years 1994 to 2000 in the Hannover area. The injury distribution will report about 741 occupants with rollover accident event. The presented paper will give an overview of the accident situations following in rollover movements of cars. The distributions of injury frequencies, injury severity AIS for the whole body and for the body regions of occupants will be presented and compared to technical details like the impact speed and the deformation pattern. The speed of the car was determined at the point of rollover and on the point of accident initiency. The characteristics of the kinematics followed in a rollover movement are analyzed and the major defined types of rollover will be shown in the paper. The paper will describe the possibilities of In-Depth Investigation methods for the approach of finding countermeasures on the example of car accidents with rollover and explaining the biomechanics of injuries in rollover movements.
This contribution introduces a number of psychological methods of analysis that are based on the practice-oriented collection of information directly at the site of an accident and that allow for an analysis and coding of the accident causes. Investigation examples and examples of the data combinations with basic medical and technical data are outlined. Objective of the collection is the inter-disciplinary investigation of human factors in the causes of accidents ("human-factor-analysis"). The psychological data are incorporated according to an integrative model for accident causes based on empiric algorithms in the data base of the accident research, where the clustered evaluation potential of comprehensive factors of the accident development can be illustrated. The central theoretical concept for the basic model of the progress of the accident from a psychological point of view comprises psychological indicators for the evaluation of the site of the accident for the analysis of the perception conditions as well as a classification of the gleaned data into the accident progress model according to chronological and local criteria. Perception conditions, action intentions and executions as well as conditions limiting perception and actions are acquired, using a questionnaire for persons involved in an accident, and are also integrated into the data structure concerning weighted feature characteristics as well as combined with other relevant features. Suitable systematization tools for the collection and coding of psychological accident development parameters have to be provided, which require primarily a model image of the corresponding processes from the persons involved in the accident (perceptions, expectations, decisions, actions). The interactive accident model contains components of the models by KÜTING 1990, MC DONALD 1972, SURREY 1969 and RASMUSSEN 1980. Based on the inter-action of the three partial systems "person", "vehicle" and "environment", the first step is the assessment of the situation by the persons involved in the accident. This is dependent on the personal attitudes and motives, on experiences and expectations concerning the progress of the situation. Subsequently, data concerning the manner of the coping with the ambiguous state as well as with the instable state (emergency reaction immediately before the accident occurs) are collected. The factors relating to the persons involved in the accident are gathered on several levels using corresponding questionnaires. The coding of the found and collected characteristics is conducted in a multidimensional evaluation relating to the technical results of the accident reconstruction and of the psychological classification, which are subsequently integrated in coded form into the data base of the accident research. The result of this analysis is a description of the development of the accident depicted on a chronological vector from a perception and decision theoretical perspective. This is explained in detail using exemplary cases.
The second ESAR Conference took place at the Medical University Hannover. This year conference presents the current state of affairs of relevant research activities in the field of in-depth investigations. The first conference on ESAR (Expert Symposium on Accident Research) was established in 2004. It is planned to hold ESAR every two years. Hannover seems to be the right place for this conference concerning the fact that the first in-depth research team was found here in the year 1973 and comprehensive studies on accident analysis were spread out from here around the world continuously. This year conference topped all expectations in terms of the numbers of participants, in the variety of papers and the interdisciplinary of presenters from medical, psychological and engineering background. More than 100 delegates from all over the world, that means 13 different countries and from 4 different continents, came to Hannover, presented their results of accident investigation and discussed countermeasures for accident prevention and injury reduction. ESAR should be a platform for exchange of knowledge to find an optimized way for increase of traffic and vehicle safety by in-depth investigation and methodology. ESAR as international conference should be a platform for consideration of all nations round the world. This seems to be very important for the current situation, having high safety in the high industrial countries of Europe, US and Australia, but low safety and high injury risk in Asia and Africa.
In the context of this study, different data sources for accident research were examined regarding their possible data access and evaluated concerning the individual quality and extent of the data. Analyses of accidents require detailed and comprehensive information in particular concerning vehicle damages, injury patterns and descriptions of the accident sequence. The police documentation supplies the basic accident statistics and is amended in the context of the forensic treatment by further information, e.g. by medical and technical appraisals and witness questionings. As a new approach to the data acquisition for the analysis of fatal traffic accidents, the information was made usable which was collected by the police and by the investigations of the public prosecutor. The best strategy for obtaining reliable, extensive and complete data consists of combining the information from these two sources: the very complete, but elementary statistic data of the Niedersächsisches Landesamt für Statistik (Lower Saxony State Authority of Statistics), based on the police documentation as well as the very extensive accident information resulting from the investigation documentation of the public prosecutor after conclusion of the procedure, the so-called Court Records. Of all 715 fatal traffic accidents, which happened in the year 2003 in the German State of Lower Saxony, 238 cases were selected by means of a statistically coincidental selective procedure based on a statistically representative manner (every third accident). These cases cover the investigation documents of the 11 responsible public prosecutor- offices, which were requested and evaluated while preserving the data security. Of the 238 cases 202 cases were available, which were individually coded and stored in a data base using 160 variables. Thus a data base of a sample of representative data for fatal accidents in Lower Saxony was set up. The data base contains extensive information concerning general accident data (35 variables), concerning road and road surface data (30 variables), concerning vehicle-specific data (68 variables) as well as concerning personal and injury data (27 variables).
The use of proper child restraint systems (CRS) is mandatory for children travelling in cars in most countries of the world. The analysis of the quantity of restrained children shows that more than 90% of the children in Germany are restrained. Looking at the quality of the protection, a large discrepancy between restrained and well protected children can be seen. Two out of three children in Germany are not properly restrained. In addition, considerable difference exists with respect to the technical performance of CRS. For that reason investigations and optimisations on two different topics are necessary: The technical improvement of CRS and the ease of use of CRS. Consideration of the knowledge gained by the comparison of different CRS in crash tests would lead to some improvements of the CRS. But improvement of child safety is not only a technical issue. People should use CRS in the correct way. Misuse and incorrect handling could lead to less safety than correct usage of a poor CRS. For that reason new technical issues are necessary to improve the child safety AND the ease of use. Only the combination of both parts can significantly increase child safety. For the assessment of the safety level of common CRS, frontal and lateral sled tests simulating different severity levels were conducted comparing pairs of CRS which were felt to be good and CRS which were felt to be poor. The safety of some CRS is currently at a high level. All well known products were not damaged in the performed tests. The performance of non-branded CRS was mostly worse than that of the well known products. Although the branded child restraint systems already show a high safety level it is still possible to further improve their technical performance as demonstrated with a baby shell and a harness type CRS.
Bicyclists are minimally or unprotected road users. Their vulnerability results in a high injury risk despite their relatively low own speed. However, the actual injury situation of bicyclists has not been investigated very well so far. The purpose of this study was to analyze the actual injury situation of bicyclists in Germany to create a basis for effective preventive measures. Technical and medical data were prospectively collected shortly after the accident at the accident scenes and medical institutions providing care for the injured. Data of injured bicyclists from 1985 to 2003 were analyzed for the following parameters: collision opponent, collision type, collision speed (km/h), Abbreviated Injury Scale (AIS), Maximum AIS (MAIS), incidence of polytrauma (Injury Severity Score >16), incidence of death (death before end of first hospital stay). 4,264 injured bicyclists were included. 55% were male and 45% female. The age was grouped to preschool age in 0.9%, 6 to 12 years in 10.8%, 13 to 17 years in 10.4%, 18 to 64 years in 64.7%, and over 64 years in 13.2%. The MAIS was 1 in 78.8%, 2 in 17.0%, 3 in 3.0%, 4 in 0.6%, 5 in 0.4%, and 6 in 0.2%. The incidence of polytrauma was 0.9%, and the incidence of death was 0.5%. The incidence of injuries to different body regions was as follows: head, 47.8%; neck, 5.2%, thorax, 21%; upper extremities, 46.3%; abdomen, 5.8%; pelvis, 11.5%, lower extremities, 62.1%. The accident location was urban in 95.2%, and rural in 4.8%. The accidents happened during daylight in 82.4%, during night in 12.2%, and during dawn/dusk in 5.3%. The road situation was as follows: straight, 27.3%; bend, 3.0%; junction, 32.0%; crossing, 26.4%; gate, 5.9%; others, 5.4%. The collision opponents were cars in 65.8%, trucks in 7.2%, bicycles in 7.4%, standing objects in 8.8%, multiple objects in 4.3%, and others in 6.5%. The collision speed was grouped <31 in 77.9%, 31-50 in 4.9%, 51-70 in 3.7%, and >70 in 1.5%. The helmet use rate was 1.5%. 68% of the registered head injuries were located in the effective helmet protection area. In bicyclists, head and extremities are at high risk for injuries. The helmet use rate is unsatisfactorily low. Remarkably, two thirds of the head injuries could have been prevented by helmets. Accidents are concentrated to crossings, junctions and gates. A significant lower mean injury severity was observed in victims using separate bicycle lanes. These results do strongly support the extension or addition of bicycle lanes and their consequent use. However, the lanes are frequently interrupted at crossings and junctions. This emphasizes also the important endangering of bicyclists coming from crossings, junctions and gates, i.e. all situations in which contact of bicyclists to motorized vehicles is possible. Redesigning junctions and bicycle traffic lanes to minimize the possibility of this dangerous contact would be preventive measures. A more consequent helmet use and use and an extension of bicycle paths for a better separation of bicyclists and motorized vehicle would be simple but very effective preventive measures.
This study aimed to identify the occurrence, type and mechanisms of the traumatic injuries of the vulnerable road users in vehicle collisions, and to determine the effects of human, engineering, and environment factors on traffic accidents and injuries. The pedestrian accident cases were collected in the years 2000 to 2005 from Changsha Wujing hospital China and Accident Research Unit at Medical University Hannover in Germany. A statistic analysis was carried out using the collected accident data. The results from analysis of Changsha data were compared with results from analysis of GIDAS data Hannover. The injury severities were determined using AIS code and ISS values. The results were presented in terms of cause of injuries, injury distributions, injury patterns, injury severity. The factors influenced the injury outcomes were proposed and discussed for the vehicle transport environment and road users. The results were discussed with regard to accident data collection, accident sampling and injury distributions etc. In the urban area of Changsha, motorcycles and passenger cars are most frequently involved in vehicle pedestrian accidents. Head and lower extremities injuries are the predominant types of pedestrian injuries. The pedestrian accidents were identified as vital issue in urban traffic safety and therefore a high priority should be given to this road user group in research of safe urban transportation. In Hannover area, cars are most frequently involved in traffic accidents, injured pedestrians are involved in road traffic of Germany in 13% of all causalities only in 2005 and have nearly the same number as motorcyclists, but the half of bicyclists.
The field of safety in road tunnels has always been an important issue for operators, owners and the responsible authorities. After the tunnel accidents in 1999 the subject gained however in importance. On European level the Directive 2004/54 EC on "Minimum safety requirements for tunnels in the Trans European Road network" has been published. This guideline has to be implemented into national law by all Member States. According to the guideline all Member States of the European Community shall develop a methodology for risk analyses to be applied in certain cases. For Germany, a standardized methodology for a probabilistic quantitative risk assessment has been worked out.
Germany's road infrastructure grew over centuries to become the arteries and lifelines of our society. The present safety of the infrastructure has to be ensured under consideration of environmental aspects. At the same time the owner has to make sure that the maintenance activities are carried out in the most efficient way. Considering the fact that financial resources are restricted, maintenance costs have to be spent in a way to obtain the greatest possible benefit. In the case of bridges, which are one of the most important parts of the road infrastructure in Germany, this task is supported by the application of a bridge management system (BMS). The existing German BMS contains assessment and optimization procedures on object and network level and is the basis for advancements to meet future demands. Developments concern life cycle and quality-oriented, holistically optimized procedures. Reasonable infrastructure management will contribute to meeting efficiency and sustainability objectives and to achieving interoperability. Here holistic network infrastructure management methods are required. There is a strong need for management solutions during the whole service life of a structure. The definition of criteria for evaluation of the relevance of failure mechanisms, including acceptance thresholds, requires the availability of relevant data for management procedure. Tools for innovative investigation methods and an effective data management will help in meeting the requirements. Relevant fields of research are improved maintenance strategies to meet future demands concerning heavy goods traffic, application and further development of nondestructive testing methods for efficient and sustainable management structures, and the improvement of analytic management tools to meet future demands.
At the beginning of the year 2000 the European Commission set the goal to halve the number of road deaths till the year 2010. The main focus are passenger car and lorry traffic. A significant reduction of the accident data could be reached in these groups. The advancement of active vehicle safety systems is an important issue of the programme. The safety of the motorcycle traffic has been disregarded till now. Since 1991 the number of killed motorcycle riders per year has been constant. The number of killed passenger car occupants has been more than halved in the same period. This is why initiatives are caused for the increase of the motorcycle safety. A great safety potential is expected for the Antilock Brake System (ABS). ABS for motorcycles is considered from the economic view in this study. A cost-benefit analysis shall clarify whether the economic benefit of ABS for motorcycles is greater than the consumed resources. Moreover, a sensitivity analysis will determine the maximal justifiable consumption in resource for which ABS is worthwhile. After the sensitivity analysis is done a break-even analysis will determine the market price respectively the annual mileage from which on ABS is worthwhile on user level. For this the fair end consumer market price is calculated which the user is ready to pay. For the considered market prices the annual mileage is determined from which on ABS is worthwhile for the user. The considered time horizon for this analysis are the years 2015 and 2020. For each of these years the accident data is forecasted. At this, it is assumed that the frequency of having an accident per million registered motorcycles decreases based on the present trend. Thus, riding motorcycle gets safer. Hence, the accident data in the years 2015 and 2020 is lower than the accident data today. The cost-benefit analysis is done for each year for four scenarios. Two scenarios handle the market penetration. The first one is the trend scenario, the second one is the mandatory equipment from the year 2010 on. The other scenarios describe the effectiveness of ABS. The effectiveness rates are determined by a literature review. The only potential which can be considered due to the available data is the potential due to an avoiding of the downfall just before the real accident happens. According to this the number of accidents will decrease by 2.4 %. The number of fatalities will decrease by 12.1 %. The number of severe injuries decreases by 11.7 %. However, the number of slight injuries increases by 2.1 %. The mentioned effectiveness rates are valid for the scenarios with the high effectiveness. Even these figures underestimate the actual effectiveness because there are only considered the avoided accidents with downfall. The necessary consumption in resources depends on the produced volume. The more ABS systems are produced, the lower are the costs per system. This is due to realised effects of scale and effects out of learning curves. The system costs depend on the penetration rate. In the trend scenario the system costs for ABS are 120 Euro for the year 2015 respectively 105 Euro for the year 2020. In the mandatory scenario the system costs are 115 Euro for the year 2015 respectively 100 Euro for the year 2020. The benefit-cost ratios are all over the critical barrier of 1.0. Thus, ABS is worthwhile on economic level. In the scenarios with high effectiveness the benefit-cost ratios range between 4.6 and 4.9. Thus, the values are even above the barrier of 3.0. The result of the break-even analysis is that ABS is worthwhile on user level. The considered market prices are 400 Euro in 2015 and 300 Euro in 2020. They are clearly below the determined fair end consumer market prices. The fair end consumer price for the year 2015 is 701 Euro respectively 622 Euro for the year 2020. Thus, ABS is worthwhile for motorcycle riders with an annual mileage higher than 2,200 km (year 2015) respectively 1,900 km (year 2020). The annual mileage of a motorcycle rider is 3,900 km on average. Thus, ABS is worthwhile for most of the motorcycle riders. The mentioned results are valid for the high effectiveness scenarios.
In September 2004 the first international symposium called ESAR (Expert Symposium on Accident Research) was carried out at the University of Hannover (Germany). The idea for such international conference was to bring together experts from the fields of accident investigation teams worldwide to present their results for a common audience of people from government, industry and other universities. The first conference was a really sufficient one and followed by the second symposium also at the Hannover Medical School two years later in 2006. This two year rhythm was now continued with the third conference in Hannover again in 2008. It is planned to carry out ESAR every two years also in the future. ESAR is a scientific colloquium and can be seen as a platform for exchange of information on accident research issues based on methodologies of investigation, injury mechanisms and injury assessment, accident causation and other issues of statistical accident data analysis. Representatives from authorities as well as from medical and technical institutions come together to discuss new research issues and exchange experiences on accident prevention and the complex field of accident reconstruction. Special focus was given to the target the European Union set for itself in 2000 which stipulates that within 10 years the number of person killed in road traffic accidents must be cut in half. To reach this goal, optimized measures, comprehensive research and analysis are necessary. A key hurdle comes from the European Union extension to 27 member states, each featuring different levels of traffic safety standards and different accident scenarios. Existing results from long term research projects in Europe, the USA, Australia and Japan including analyses of infrastructure, population, vehicle fleet and driver behaviour offer an excellent basis for understanding and improving countermeasures and research support needs in underdeveloped countries. ESAR's goal is to bring together researchers from all parts of the world, who will report on their methods and recommendations to improve traffic safety based on "In-Depth-Investigations" of real world accidents. These In-depth-investigations of accidents require thorough documentation and an accident data analysis on multidisciplinary levels which must be carried out immediately after it occurs. ESAR presents scientists the opportunity to present their studies on a common basis of research level.
Technical progress in automotive engineering focuses at the moment on two competing branches: improving safety and reducing energy consumption. Recent consideration has been given to a third factor, cost to the consumer. Challenges are presented by demographic changes, especially with increasing participation of elderly people in road traffic. The report considers the recent history of road accidents in Germany and statistics relating to vehicle population and road performance. There is a general trend towards decreasing numbers of accidents and their severity. Transport is responsible for roughly 20% of CO2 emissions and approximately 70% of total petroleum consumption. The Federal Government has responded to these challenges by publishing the Freight Transport and Logistics Masterplan in the summer of 2008. It describes the strategic transport policy direction and the key elements of the future course of action which are to be used to ensure the provision of efficient infrastructure and, at the same time, to reduce the amount of energy consumed by vehicles and make transport more efficient, cleaner and quieter. This document contains a number of concrete measures subsumed under the following six objectives: Making optimum use of transport infrastructure - shaping transport to make it more efficient; Reducing the number of journeys - ensuring mobility; Transferring more traffic to the railways and inland waterways; Upgrading more transport arteries and hubs; Environmentally friendly, climate friendly, quiet and safe transport, and Good working conditions and good training in the freight transport industry. Progress in research is outlined in the following areas: Daytime Running Lights for Motorcycles; Safety of hydrogen vehicles - addressing safety and environmental issues by development of a Global Technical Regulation for hydrogen vehicles; Elements of active vehicle safety for elderly drivers; Periodical Technical Inspection of electronically controlled systems in road vehicles - Electronic Stability Control; Pedestrian protection; Crash Compatibility - role of collision partner in passive safety tests; Child safety; Euro NCAP - Child Restraint Systems, and German Field Operational Test on Car-to-Car and Car-to-Infrastructure Systems (SIM-TD). The research project AKTIV - "Adaptive and Cooperative Technologies for Intelligent Traffic" encompasses the design, development, and evaluation of novel driver assistance systems, knowledge and information technologies and is set up to find solutions for efficient traffic management and Car-to-Car and Car-to-Infrastructure communication for future cooperative vehicle applications. The European Statement of Principles on the Human Machine Interface (HMI), presented at the eSafety Conference, which was held in Berlin on 5/6 June 2007, addresses issues such as Real Time Traffic Information (RTTI), Legal issues of Advanced Driver Assistance Systems (ADAS) and e-security.
