Road authorities, freight, and logistic industries face a multitude of challenges in a world changing at an ever growing pace. While globalization, changes in technology, demography, and traffic, for instance, have received much attention over the bygone decades, climate change has not been treated with equal care until recently. However, since it has been recognized that climate change jeopardizes many business areas in transport, freight, and logistics, research programs investigating future threats have been initiated. One of these programs is the Conference of European Directors of Roads (CEDR) Transnational Research Programme (TRP), which emerged about a decade ago from a cooperation between European National Road Authorities and the EU. This paper presents findings of a CEDR project called CliPDaR, which has been designed to answer questions from road authorities concerning climate-driven future threats to transport infrastructure. Pertaining results are based on two potential future socio-economic pathways of mankind (one strongly economically oriented "A2" and one more balanced scenario "A1B"), which are used to drive global climate models (GCMs) producing global and continental scale climate change projections. In order to achieve climate change projections, which are valid on regional scales, GCM projections are downscaled by regional climate models. Results shown here originate from research questions raised by European Road Authorities. They refer to future occurrence frequencies of severely cold winter seasons in Fennoscandia, to particularly hot summer seasons in the Iberian Peninsula and to changes in extreme weather phenomena triggering landslides and rutting in Central Europe. Future occurrence frequencies of extreme winter and summer conditions are investigated by empirical orthogonal function analyses of GCM projections driven with by A2 and A1B pathways. The analysis of future weather phenomena triggering landslides and rutting events requires downscaled climate change projections. Hence, corresponding results are based on an ensemble of RCM projections, which was available for the A1B scenario. All analyzed risks to transport infrastructure are found to increase over the decades ahead with accelerating pace towards the end of this century. Mean Fennoscandian winter temperatures by the end of this century may match conditions of rather warm winter season experienced in the past and particularly warm future winter temperatures have not been observed so far. This applies in an even more pronounced manner to summer seasons in the Iberian Peninsula. Occurrence frequencies of extreme climate phenomena triggering landslides and rutting events in Central Europe are also projected to rise. Results show spatially differentiated patterns and indicate accelerated rates of increases.
The presence and performance of Advanced Driver Assistance Systems (ADAS) has increased over last years. Systems available on the market address also conflicts with vulnerable road users (VRUs) such as pedestrians and cyclists. Within the European project PROSPECT (Horizon2020, funded by the EC) improved VRU ADAS systems are developed and tested. However, before determining systems" properties and starting testing, an up-to-date analysis of VRU crashes was needed in order to derive the most important Use Cases (detailed crash descriptions) the systems should address. Besides the identified Accident Scenarios (basic crash descriptions), this paper describes in short the method of deriving the Use Cases for car-to-cyclist crashes. Method Crashes involving one passenger car and one cyclist were investigated in several European crash databases looking for all injury severity levels (slight, severe and fatal). These data sources included European statistics from CARE, data on national level from Germany, Sweden and Hungary as well as detailed accident information from these three countries using GIDAS, the Volvo Cars Cyclist Accident database and Hungarian in-depth accident data, respectively. The most frequent accident scenarios were studied and Use Cases were derived considering the key aspects of these crash situations (e.g., view orientation of the cyclist and the car driver- manoeuvre intention) and thus, form an appropriate basis for the development of Test Scenarios. Results Latest information on car-to-cyclist crashes in Europe was compiled including details on the related crash configurations, driving directions, outcome in terms of injury severity, accident location, other environmental aspects and driver responsibilities. The majority of car-to-cyclist crashes occurred during daylight and in clear weather conditions. Car-to-cyclist crashes in which the vehicle was traveling straight and the cyclist is moving in line with the traffic were found to result in the greatest number of fatalities. Considering also slightly and seriously injured cyclists led to a different order of crash patterns according to the three considered European countries. Finally the paper introduced the Use Cases derived from the crash data analysis. A total of 29 Use Cases were derived considering the group of seriously or fatally injured cyclists and 35 Use Cases were derived considering the group of slightly, seriously or fatally injured cyclists. The highest ranked Use Case describes the collision between a car turning to the nearside and a cyclist riding on a bicycle lane against the usual driving direction. A unified European dataset on car-to-cyclist crash scenarios is not available as the data available in CARE is limited, hence national datasets had to be used for the study and further work will be required to extrapolate the results to a European level. Due to the large number of Use Cases, the paper shows only highest ranked ones.
[Introduction:] A large number of road users involved in road traffic crashes recover from their injuries, but some of them never recover fully and suffer from some kind of permanent disability. In addition to loss of life or reduced quality of life, road accidents carry many and diverse consequences to the survivors such as legal implications, economic burden, job absences, need of care from a third person, home and vehicle adaptations as well as psychological consequences. Within an EU funded project MOVE/C4/SUB/2011-294/SI2.628846 (REHABIL AID) these consequences were analyzed more detailed.
In the project SECMAN " SECurity MANual " a simple four-step procedure for the identification of critical road infrastructures, assessment of these infrastructures regarding various man-made threats and the determination of effective protection measures was developed. These methodologies are summarized and combined into a comprehensive best-practice manual which allows for a trans-national structured and holistic security-risk-management approach for owners and operators of road infrastructures in Europe. This paper presents the developed methodology starting from the assessment procedures of a network's criticality over an object's attractiveness and vulnerability to the selection process of appropriate protection measures.
Improving the security of critical road infrastructure is a major task for owners and operators of tunnels and bridges in the European TEN-T Network (Trans-European Networks of Transport) (European Parliament and Council 1996). Up to now, there has not been a systematic procedure for identifying and assessing critical infrastructure objects and selecting appropriate protection measures. The EC FP7 project SeRoN for the first time presents an innovative methodology in order to support road owners and operators in handling this complex task. This paper describes the methodology and project results in detail by giving an introduction into its practical application.
Trauma management (TM) covers two types of medical treatment: the initial one provided by Emergency Medical Services (EMS) and a further one provided by permanent medical facilities. There is a consensus in the professional literature that to reduce the severity and the number of road crash victims, the TM system should provide rapid and adequate initial care of injury, combined with sufficient further treatment at a hospital or trauma centre. Recognizing the important role of TM for reducing road crash injury outcome, it was decided, within the EU funded SafetyNet project, to develop road safety performance indicators (SPIs) which would characterize the level of TM systems" performance in European countries and enable country comparisons. The concept of TM SPIs was developed based on a literature study of performance indicators in TM, a survey of available practices in Europe and data availability examinations. A set of TM SPIs was introduced including 14 indicators which characterize five issues such as: availability of EMS stations; availability and composition of EMS medical staff; availability and composition of EMS transportation units; characteristics of the EMS response time, and availability of trauma beds in permanent medical facilities. Basic information on the TM systems was collected in close cooperation with the national expert group. A dataset with TM SPIs for 21 countries was created. It was demonstrated that the countries can be compared using selected TM SPIs. Moreover, a more general comparison of the TM systems' performance in the countries is possible, using multiple ranking and statistical weighting techniques. By both methods, final estimates were received enabling the recognition of groups of countries with similar levels of the TM system's performance. The results of various trials were consistent as to the recognition of countries with high or low level of the TM systems" performance, where in grouping countries with intermediate levels of the TM system's performance some differences were observed. The SafetyNet project's practice demonstrated that data collection for estimating TM SPIs is not an easy task but is realizable for the majority of countries. The TM SPIs" message is currently limited to the availability of trauma care services. Further development of the TM SPIs should focus on characteristics of actual treatment supplied, based on combined police and medical road crash related databases.
Learner drivers are readied for their participation in motorised transport within the framework of specific, internationally-diverse preparation systems. These systems are historically developed and are characterised by country-specific economic, infrastructural, legal and cultural circumstances. With the aid of functionally-distinguishable teaching and learning methods as well as testing methods, a conceptual framework was created whilst drawing upon research-methodological approaches of comparative political science as well as teaching and learning principles that facilitated a description and analysis of the systems for a comparative observation to be performed. The systems for the preparation of learner drivers in 44 countries are illustrated in the report. The descriptions are based upon surveys of experts from various institutions (ministries of transport, driving instructor associations, testing organisations) as well as upon literary and Internet research. Alongside European countries with a traditional formal driver training, \"Graduated Driver Licensing\" systems that are primarily encountered in English-speaking countries were also taken into account when selecting the countries. They are characterised by the guarantee of gaining comprehensive driving experience under reduced risk conditions in the form of supervised driving prior to the start of independent driving as well as protective special rules for learner drivers whilst gaining further driving experience during the initial phase of independent driving. The results enable a detailed insight into the country-specific structure of learner driver preparation with the components of the formal driver training in driving schools, informal teaching and learning methods such as supervised driving, the driving tests that must be successfully completed as well as legal frameworks and quality assurance measures. The functionality of system components and architectures shall be discussed against the backdrop of evaluation findings regarding the effectiveness in terms of safety.
The European CASPER (Child Advanced Safety Project for European Roads) project studying car child safety includes a sociological approach in order to have a better understanding of the behaviour of parents driving children under 12 years old. A questionnaire was distributed via the internet in Europe with 998 parents (representing 1638 children) from 22 European countries responding. The results inform on the way parents secure their children during a car trip. Many parents did not control how their children were installed in the child restraint system (CRS). A toddler was more likely to travel into a child seat than an older child was. Regarding misuse situations, an important part of the participants did not think that they could make mistakes when fixing the child seat to the car (26%) or when placing the child into the seat (39%). This leaves an important field of action especially by communication via different media and in the CRS sale outlets.
Police records about traffic accidents like used by IRTAD (International Road Traffic and Accident Database) and CARE (Community Road Accident Database) do not represent all road injuries. For instance, road accidents of bicyclists without a counterpart are usually not reported. Furthermore, IRTAD-like data contains hardly any information on injury outcome and accident circumstances. This information gap leads to an under-representation of the safety concerns of the most vulnerable road users like children and the elderly both in accident research and safety promotion. Injury registration for the European Injury Database (IDB), in turn, combines details of accident causation with diagnostic information that can be used to assess injury severity and long term consequences. The IDB is collecting data from hospital emergency department patients and is being implemented in a growing number of countries. In this article IDB results on mode of transport and injury outcome are presented from a sample of nine EU member states.
This paper will outline ETSC's contribution to the European Union's road safety policy 2011-2020. It will present some of the main recommendations from ETSC's Blueprint for the 4th Road Safety Action Programme and will introduce the response to the European Commission's Road Safety Policy Orientations 2011-2020 (published July 2010). The second framework document presented is the Transport White Paper (published March 2011). The paper will focus on new targets and the new vision set for Europe's Road Safety policy picking out some issues in particular such as traffic law enforcement and the protection of vulnerable road users. It will argue that by reinforcing the current Road Safety Policy Orientations, the EU will be better placed to reach its new ambitious goal of halving road deaths by 2020 and the longer term zero casualty vision.
