公路线形设计安全性评价仿真

Simulation of road alignment design safety evaluation

结合公路设计规范,综合考虑车辆动力学性能、气候等影响因素,通过对吉林省安图至二道白河二级公路不同线形路段的仿真,对道路安全进行了综合评价,为分析研究公路线形对交通安全的影响要素奠定了基础。提出了公路线形设计规范与安全标准相融合的理念,为我国公路设计安全性审核提供参考。

Combining with the road design norm, considering the dynamic performance of the vehicle and the climatic environment of the road, the road safety in the design drawing stage of the second class highway from Antu to Erdobaihe,Jilin Province, was evaluated by the simulation study of the different road alignments. The essential factor analysis about the effect of the road alignment on the traffic safety was studied. A concept of the mixing of the road alignment norm with the safety standard was suggested to provide a reference for the examination and verification of the road design safety.
