重庆市公路典型路段交通安全仿真评价与安全

Traffic Safety Simulation Evaluation and Safety of Typical Road Sections in Chongqing

在我国交通事业不断快速发展、公路里程不断突破的今天,公路交通安全也越来越被更多学者所关注,对道路交通安全评价的研究越来越成熟。现依据重庆市公路的特点,选取某连续弯道以及长大下坡的典型路段为例,以交通仿真技术为基础,基于Carsim软件建立道路安全仿真模型,得出连续急弯路段的交通安全判定标准;采用多重线性回归建立预测模型,对此路段的交通安全作出了合理的评价,并给出此路段的安全改进方法,为本市交通安全评价积累经验。

Today,with the rapid development of China's transportation industry and the continuous breakthrough of highway mileage,highway traffic safety has been paid more and more attention by scholars.The research on road traffic safety evaluation is more and more mature.Based on the characteristics of Chongqing highway,a typical section of continuous curve and long downhill is selected as an example.Based on traffic simulation technology,the road safety simulation model is established based on Carsim software,and the traffic safety judgment standard of continuous sharp bend section is obtained.The multi-linear regression is used to establish the prediction model,and the traffic safety of this section is reasonably evaluated.The safety improvement method of this section is given,and the experience of traffic safety evaluation for this city is accumulated.
