济青高速改扩建施工保通方案仿真与评价

为了满足日益增长的交通流量和社会经济发展需求,提高济青高速通行能力,济青高速公路改扩建施工。工程采用"两侧拼宽"的方式,将道路扩建为双向八车道高速公路。本文依托此工程,通过VISSIM软件对道路改扩建交通组织下交通流特性进行分析,基于交通流特性、考虑安全设施等其他因素建立评价模型,进行改扩建高速公路安全评价。

Simulation and Evaluation of the Traffic Protection Scheme for the Reconstruction and Extension of Jiqing Expressway

In order to meet the increasing traffic flow and socio-economic development needs,and to improve the capacity of Jiqing Expressway,the reconstruction of Jiqing Expressway was expanded. The project adopts the method of "widening the width on both sides" to expand the road into a two-way eight-lane expressway. Relying on this project,this paper analyzes the characteristics of the traffic flow under the road reconstruction and expansion traffic organization through VISSIM software,establishes an evaluation model based on the traffic flow characteristics,and considers other factors such as safety facilities to carry out the safety evaluation of the reconstruction and expansion of the highway.
