With the aim of identifying suitable indicators and criteria for evaluating the safe human-machine interaction for SAE level 3 systems up to 60 km/h in the context of automated driving, this research project has started with a focus group interview to identify relevant publication channels and list of keywords regarding indicators for the evaluation of human-machine interaction at SAE Level 3. Based on the identified list of keywords, literature reviews have been conducted to extract relevant publications from the identified publication channels. According to the defined inclusion and exclusion criterion, 38 papers have then been selected and used for meta-analysis to study the influence of different takeover situations on takeover performances. The results of meta-analysis have indicated that drivers’ takeover performances measured by the categories of takeover time, takeover quality and subjective workload are different in static and dynamic situations. After that, expert interviews have been conducted with six international experts to help interpret the results of meta-analysis and develop checklist items. In the end, 16 checklist items assigned in six categories of system requirements have been developed and can be used by international experts to evaluate the safety of the human-machine interaction of SAE Level 3 systems up to 60 km/h in production vehicles. This checklist has been further developed to an online application, which can be used as an easy-to-implement and efficient evaluation procedure in relation to the traffic safety relevant interaction quality of the system.

The focus of the Annual Report 2020 is on selected research results from all fields of activity of the BASt.
Among the topics are for example the re-evaluation of the alcohol ban for novice drivers, the effectiveness of emergency braking systems for trucks or risk factors in motorbike traffic. ‘Talking’ workplaces will be discussed as well as the communication of automated vehicles with non-automated road users and airbag safety systems for cyclists.
The traffic barometer shows how traffic developed during the Corona pandemic. Also presented are technical developments to avoid road closures, the RITUN guide for resilient road tunnels, concrete roadway 4.0, how occupational safety demands and promotes innovation, and cross-national research cooperation in road construction.
Results on safe rural roads through suitable protective devices, on the use of digital technologies in engineering structures, on sustainable innovative replacement of concrete bridges as well as BASt activities in the BMVI Network of Experts are also presented.
Highlights as well as facts and figures complete the report.
Annual Report 2019
(2020)
In its Annual Report 2019, the BASt has compiled a selection of its research. For example, the climate impact analysis, among other things, describes an essential research focus for the federal main road network. The new information and evaluation platform "BaustellenCheck" is presented, and reports on digitization in road equipment and maintenance as well as on various activities on the innovative test site duraBASt.
The results of current simulator and test track studies are also part of the annual report, as are the results of level 3 automation studies in real road traffic with an appropriately equipped test vehicle. Approaches to solutions for the infrastructure requirements of automated driving on motorways and federal trunk roads are presented, as well as the current status of the development of regulations in the field of vehicle technology.
The BASt scientists investigated the significance of virtual reality in road safety work. Whether influencers can be used effectively in road safety communication was also considered, as well as other proposed measures to reduce the risk of accidents, especially among young novice drivers.

Traditionally, traffic count statistics in Germany contain the so-called relevant hourly volume, which is defined as the 30th-highest hour of the year when listing the hourly volumes in descending order. When the first edition of the German Highway Capacity Manual (HBS) was prepared in 2001, the Federal Government decided that this 30th hour should be used as the basis for the level of service determination for all Federal freeways and trunk roads. While German freeways are quite well equipped with inductive loop detectors, there are much fewer counts on rural roads and almost no long-term data on urban roads. With the current redraft of the German HBS detailed advice will be given on how to estimate peak-hour demand (all vehicles and heavy vehicle portion), based on the n-th highest hour concept depending on the available traffic counts. As the HBS will be divided into three major parts: freeways, rural roads, and urban roads, three separate chapters for the peak-hour demand estimation will be provided. Whereas for freeways the task consists in finding the comparable site equipped with inductive loop detectors, for urban roads it is a matter of establishing which time periods of the year and weekdays are appropriate for manual short-term counts as estimation of the 30th hour of the year. For all kind of traffic devices the requirements on traffic demand models for level of service calculations are described.
Annual report 2018
(2019)
With this annual report, BASt is giving the 2018 research year a face. A part of its work is present and in the focus of the public, for example the field test of long trucks, the unique research area duraBASt at the motorway junction Cologne East or the innovative measuring vehicle MESAS for the condition assessment of road surfaces in flowing traffic. A large part of the BASt's work is less effective in attracting public attention but no less important, such as the essential updating of regulations, the testing and approval of products and processes, and the compilation of forecasts and statistics. More than 50 employees report on their research activities and thus give an insight into the tasks of BASt with its core areas of vehicle technology, traffic safety, traffic engineering, road construction as well as bridge and civil engineering. Highlights as well as facts and figures in short and concise form complete the report.
In 2016 the seventh ESAR conference (Expert Symposium on Accident Research) was held in Hannover. ESAR is an international convention of experts, who analyze traffic accidents all over the world and discuss their results in this context, conducted at the Medizinische Hochschule Hannover every 2 years. It connected representatives of public authorities, engineers in automotive development and scientists and offers a forum with particular emphasis on In-Depth-Analyses of accident statistics and accident analyses. Special focus is placed on research on the basis of so-called "In-Depth-Accident-Investigations" [data collections at the sites of the accidents], which are characterized by extensive documentations of the sites of the accidents, of the vehicles as well as of the injuries, encompassing several scientific fields. ESAR aims at a multi-disciplinary compilation of scientific results and at discussing them on an international, scientific level. It is thus a scientific colloquium and a platform for exchanging information for all accident researchers. Experiences in accident prevention as well as in the complex field of accident reconstruction are stated and new research fields are added. Existing results of long-term research work in Europe, the US, Australia and Japan include different infrastructural correlations and give findings on population, vehicle population and driver characteristics, which offer a basis for recommendations to be derived and measures for increasing road safety.
Recently, EuroNCAP updated the upper legform test protocols. The main objective of this study is to establish the upper legform test in KIDAS (Korean In-depth Accident Study) taking into account domestic pedestrian accident data as well as anthropometric data to protect elderly pedestrians whose average height and weight is much smaller and lighter than other age groups, especially compared to Europeans. Therefore 230 cases of pedestrian accidents from KIDAS were investigated to explore the injury severity of body regions as well as age related injury patterns. Injuries of all body regions were examined, with a special focus on injuries of abdomen and pelvic area. On the other hand, in order to explore Korea's pedestrian accident environment, national police data and KIDAS (Korean In-depth Accident Study) data were compared. The results should be taken into account in future analyses and possible improvements, such as regulations and KNCAP test protocols, of the pedestrian safety policy in Korea.
[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.
