Evaluation of Vehicle-Road Suitability Analysis on Highway by Accident OR Comparison

摘要

Both vehicles and roads are important elements of a roadway transportation system. Vehicles should run in coordination with roads when moving goods or passengers. Good suitability of vehicle-road is a necessary condition of transport operating safety. However, there is a lack of research for evaluating this suitability. This article analyzes a dataset of statistical traffic accidents on highways in China from 2010 to 2014. Then, it studies the quantitative description of the suitability of vehicle-road with respect to traffic safety. As a result, an evaluation method is developed for multitype vehicles, using accident odds ratios comparison. The main finding is that trucks have an accident odds ratio four times greater than passenger vehicles. Conclusions will provide support for how to coordinate the relationship between vehicle and road in order to improve vehicle running safety.
