Incorporating Traffic Control and Safety Hardware Performance Functions into Risk-based Highway Safety Analysis

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 ...

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...

Application of Simulation-based Traffic Conflict Analysis for Highway Safety Evaluation

Highway safety evaluation is one of the critical processes for identifying transportation system performance. The capabilities of common used safety assessing methodologies such as naïve before-after comparisons, safety audit, and statistical modelling, etc, are limited due to historical data availability, observation periods, or observer’ experience, and so on. Other than these traditional met...

Control of Robotic Highway Safety Markers

Proper traffic control is critical in highway work zone safety. Traffic control devices such as signs, barricades, cones, and safety barrels are used. Automated safety devices could improve work zone design and housekeeping and therefore increase safety. This thesis presents a mobile safety barrel robot. The robotic safety barrels can self-deploy and self-retrieve — removing workers from this d...
