摘要
针对某山区互通立交工程施工图设计阶段中的匝道路段限速方案,从速度协调性、匝道线形、匝道视距、横向力系数等方面评价该限速方案的适用性。经过论证,原限速方案中存在4条受限路段,需重新对A,B,C,D 4条匝道进行限速方案设计,以保证行车安全和驾驶舒适性。然后,基于多元因素法和技术指南法重新进行受限匝道路段限速值计算,并提出新的限速方案。最后,通过VISSIM仿真软件对前后两种限速方案进行仿真与评价,仿真结果验证新限速方案更加合理,并提高车辆的通行效率。
According to the speed limit scheme of a mountain interchange interchange project,the applicability of the speed limit scheme is evaluated from the aspects of speed coordination,ramp line,tunnel line of sight and lateral force coefficient.There are 4 restricted sections in the original speed limit scheme,and the speed limit schemes of the four ramps A,B,C and D need to be redesigned to ensure driving safety and driving comfort.Then,based on multivariate factor method and the technical Guide Method,the calculation of the limited speed limit value is carried out,and the new speed limit scheme is proposed.Finally,the simulation and evaluation of the two speed limiting schemes are carried out by VISSIM simulation software.The simulation result verifies that the new speed limiting scheme is more reasonable and improves the traffic efficiency of the vehicle.
