A Design Method for the Roadside Clear Zone Based on Accident Simulation Analysis

Abstract

In order to improve the safety design of roadside areas and reduce the loss of roadside accidents, this paper uses PC-Crash software to perform an accident simulation analysis. By recording the track of the vehicle after entering the roadside, the recommended widths of the roadside clear zone for different operating speeds and horizontal curve radii in straight and curved sections are given. According to our previous research data, the conditions for setting the roadside clear zone are proposed. Finally, based on a cost-benefit ratio analysis, a comprehensive risk index method is adopted to evaluate the social stability risk of the project and conduct research on the design method of the roadside clear zone. The results show that the width of the roadside clear zone has an exponential relation with the departure speed and a power relation with the horizontal curve radius. The research results realize the accurate calculation of the roadside clear zone width and fill in the gaps of the relevant specifications and guidelines in the setting conditions of the roadside clear zone.

Analysis of Vehicle-Pedestrian Accident Risk Based on Simulation Experiments

“…Due to the high cost of real vehicle tests and considering the feasibility of computer technology simulation, some scholars have developed mature accident reconstruction software (SMAC, AUTOSMAC, PC-Crash, etc.) by building digital dummy models, providing another way to analyze and study vehicle-pedestrian collision accidents [8]. A dummy model should not only adapt to human body dynamics analysis but also be able to carry out human body damage analysis [9,10].…”
