Evaluating Highway Traffic Safety: An Integrated Approach

Traffic Safety Technology of Highway Tunnel Group

In this paper, the author studies about the traffic safety technology of highway tunnel group. In this study measured traffic safety technology in the access zone of tunnels including tunnel luminance under diverse climate conditions were measured and luminance of the threshold zone were estimated. Then operating traffic safety technology of tunnel in China was compared and analyzed and, based ...

An Integrated Approach to Evaluating Simulation Credibility

Discussions about simulation credibility tend to focus on the issue of "validation", i.e., how well simulation predictions match real world observations. While validation is certainly a most direct and intuitively accessible measure of simulation credibility, the validation process has numerous well-known limitations. Validation is by no means the only measure of simulation credibility, however...

Drowsy drivers--medical implication of highway traffic safety.

The estimates of the contribution of drowsiness and fatigue to the number of road crashes is often neglected considerably, due both to under-reporting of these factors by drivers, and technical difficulty in investigating the problem. Preventing and treating the reasons for falling asleep behind the wheel may have considerable contribution in traffic safety. Therefore the licensing authorities ...

Traffic Safety Region Estimation Based on SFS-PCA-LSSVM: An Application to Highway Crash Risk Evaluation

Accurate real-time crash risk evaluation is essential for making prevention strategy in order to proactively improve traffic safety. Quite a number of models have been developed to evaluate traffic crash risk, by using real-time surveillance data. In this paper, the basic idea of traffic safety region is introduced into highway crash risk evaluation. Traffic safety region aims to describe the s...
