Within the UDRIVE project, a rich cross-European naturalistic driving database was created which includes everyday driving data on car and truck drivers and powered two-wheeler riders. The database provides extensive, reliable insights into driving behavior in real traffic as a foundation for improving the safety and sustainability of European road...

Recent studies of the relationship between the speed of traffic and road safety, stated as the number of fatalities and the number of injury accidents, are reviewed and their results synthesised by means of meta-analysis. All studies were based on data fully or partly for years after 2000. Previously proposed models of the relationship between the...

In the future, cyclists will be sharing the roads with automated and traditional vehicles [1]. Interactions between cyclists and automated vehicles (AVs) may differ from interactions with traditional vehicles, because cyclists may hold incorrect expectations about how AVs will react to their presence, leading to confusing and risky situations. The...

The European Road Safety Decision Support System (roadsafety-dss.eu) is an innovative system providing the available evidence on a broad range of road risks and possible countermeasures. This paper describes the scientific basis of the DSS. The structure underlying the DSS consists of (1) a taxonomy identifying risk factors and measures and linking...

This report serves as background report and research account for the Road Safety Monitor 2017 (R-2017-17) and discusses: - developments in number of road fatalities and serious road injuries - developments in demographics, mobility and risk - developments in road safety indicators, and - road safety measures that have been taken

Red light running is a risky traffic violation leading to traffic conflicts at intersections that may result in death or serious injury. It has been estimated that pedestrians’ relative crash risk is eight times higher when they cross an intersection at red light instead of green (or yellow) light. Relative risk estimates for red light running by d...

This paper discusses the effect of diabetes on road safety. Diabetes mellitus is a group of metabolic diseases characterised by defects in insulin secretion, insulin action, or both. Studies generally show a (slightly) higher risk for drivers with diabetes, although differences are often not statistically significant. Two main approaches have been...

Automated vehicles are gradually entering our roadway system. Before our roads will be solely used by fully automated vehicles, a long transition period is to be expected in which fully automated vehicles, partly automated vehicles and manually-driven vehicles have to share our roads. The current report looked into the position of pedestrians and c...

The present study explores the emotional, cognitive and behavioural responses of car drivers to various traffic penalty scenarios. A representative sample of 1237 car drivers was asked to report their probable emotions, perceived fairness and behavioural intentions in reaction to various traffic penalty scenarios. Respondents were asked to imagine...

Naturalistic driving (ND) is a research method that provides insight in everyday driver behaviour. Typically, in an ND study vehicles are equipped with several small cameras and sensors, which continuously and inconspicuously register vehicle manoeuvres, driver behaviour, and external conditions. This allows observation and analysis of the interrel...

Speeding is still common practise on many roads and contributes to a significant number of crashes. Intelligent Speed Assistance (ISA) systems aim to reduce speeding in a more or less intrusive manner. This is promising, however, the acceptability of ISA systems is still very low. Another promising approach to reduce speeding is by improving the cr...

Speeding is still a common practice on many roads and it contributes to a significant number of crashes. Two new approaches to solve speeding issues are focused on: intelligent speed assistance systems (ISA) and speed limit credibility. Research has indicated that ISA is promising with respect to improving speed behaviour but has not been widely im...

PEPPER This report is the Deliverable of task 4.3a of the PEPPER project. It describes the good practice requirements regarding data, data collection and data use for monitoring and evaluating Traffic Law Enforcement (TLE). The aim is that, eventually, individual police forces/countries put the identified 'good practice' data into a European TLE mo...

The present study aimed to operationalise the concept of credible speed limits and to make a first step to elaborate it in such a way that road authorities can put the concept into practice. The study focused on the credibility of an 80 km/h limit for different rural roads and assessed the effects of characteristics of the road and its environment...

Driving speed is an important factor in road safety. Speed not only affects the severity of a crash, but is also related to the risk of being involved in a crash. This paper discusses the most important empirical studies into speed and crash rate with an emphasis on the more recent studies. The majority of these studies looked at absolute speed, ei...

Recent work in Science & Technology Studies emphasizes the social and societal component in the development of technology. Many studies in this field of work show that the actual shape of a particular technology can be interpreted as the result of negotiations in a social setting (Bijker et al., 1987, Latour, 1997). It can even be that technologies...

In an evaluation study, the effects of targeted speed enforcement on speed and road accidents were assessed. Enforcement was predominantly carried out by means of mobile radar and focused on rural non-motorway roads. Information and publicity supported the enforcement activities. The evaluation covered a period of 5 years of enforcement. The speed...

In the Netherlands, as in most other countries in the world, car mobility is increasing rapidly. The accident rates are decreasing, but the de- crease is not large enough to compensate for the extra road traffic victims brought about by the increased mobility. Without strong, innovating efforts the number of road traffic victims will increase and t...

Syria Shell Petroleum Development is a joint venture partner in major EP activities in Syria. Many road transport fatalities were associated with these activities and therefore it was decided to try to improve this grim state of affairs by executing a dedicated road safety program fully funded by Shell. Drastic improvements in the road safety stati...

This study compares the effectiveness of different approaches to training complex cognitive and psychomotor skills within the framework of road safety education for primary school children. A method involving roadside behavioral training, a classroom instruction method and a method combining these two approaches were developed to teach basic skills...

Two training methods were developed to teach young cyclists (8/9 years) how to behave in priority situations. One method was developed along the lines of the modelling principle. In earlier studies it was shown that this method is effective in teaching crossing strategies to young pedestrians. The other training method was based upon Anderson's Ada...

A number of factors related to bicycle accidents were studied, namely, knowledge of priority rules, attitude and self-reported behavior regarding traffic rules, and general opinions about the safety of the traffic behavior of cyclists and drivers. In order to get an indication of the influence of these factors at different stages of the life span,...

One of the most challenging areas for ITS to contribute to road safety is controlling speed behaviour. Speeding is still common practise on many roads and contributes to a significant number of crashes. An Intelligent Speed Assistance (ISA) aims to reduce speeding in a more or less intrusive manner. This is promising, however the acceptance of ISA...
