The nature and the effects of improving road traffic safety by infrastructure redesign and Advanced Driver Assistance Systems (ADAS) are different. This makes comparison of such measures difficult, especially because relevant effect data for ADAS are not yet available. To address this issue, a conceptual model is presented for the effects of road traffic safety measures, based on a breakdown in...

1 This study evaluates the safety effects of automated mobile enforcement on urban arterial roads. 2 The before-and-after Empirical Bayes (EB) method was used to account for the regression-to3 the-mean effects and other confounding factors. Locally developed safety performance functions 4 and yearly calibration factors for different collision severities were obtained by using a reference 5 grou...

This paper presents a deterministic approach for performance assessment of different province’s road safety level at Iran. A data envelopment analysis (DEA) model considering undesirable input and output indices and a multivariate statistical method, principle component analysis (PCA) are used in this paper, while previous studies do not use composite PCA-DEA method and undesirable input and ou...

Motorcyclists make up the largest group of fatalities on Malaysian roads, majority succumbing to head injuries despite the compulsory safety helmet laws in the country. One possible reason for this high fatality is improper usage of safety helmets. This study examines the compliance of proper safety helmet use in motorcyclists in a typical Malaysian town. Five hundred motorcyclists were studied...

Over the last forty years, safety on Australian roads has significantly improved in part because of the adoption of aviation safety technologies. The best known of these adaptations are: safety belts; anti-skid braking; dashboard/control layout improvement and the use of computers to aid stability and performance. The improvement in safety on the road as reflected by reductions in road trauma h...

in vehicular ad hoc networks there is the ability to communicate between vehicles. this communication which is wireless should be rapid and reliable. these networks have unique characteristic. this communication among vehicles has many advantages in safety and comfort applications. since, the roads are always encountered to accidents and risks, using optimized tools could be useful in these sit...

In order to reduce the amount of traffic accidents on the roads, new safety systems based on vehicular communication – which allows vehicles to exchange information with nearby vehicles – are being developed. Similar to wireless communication in other domains, this type of information exchange is threatened by various kinds of attacks that could outweigh the advantages of safety applications an...

The use of tolls is being widespread around the world. Its ability to fund infrastructure projects and to solve budget constraints have been the main rationale behind its renewed interest. However, less attention has been payed to the safety effects derived from this policy in a moment of increasing concern on road fatalities. Pricing best infrastructures shifts some drivers onto worse alternat...

Variable Speed Limits (VSL) is an Intelligent Transportation Systems (ITS) control tool which can enhance traffic safety and which has the potential to contribute to traffic efficiency. Queensland's motorways experience a large volume of commuter traffic in peak periods, leading to heavy recurrent congestion and a high frequency of incidents. Consequently, Queensland's Department of Transport a...
