基于VISSIM的次干路进口道车道集散功能优化设计策略
首发时间:2020-01-06
摘要:为解决城市次干路在现状运行和功能定位方面存在的问题,以次干路的集散功能为导向,以车道数和车道功能划分为对象,提出一种面向功能的次干路交叉口进口道车道形式优化设计策略。基于VISSIM模拟,以行程延误为指标,对"双向2车道"、"双向3车道"、"双向4车道"等次干路交叉口形式完成集散功能的能力进行对比分析。结果表明:"双向3车道"是值得推荐的能基本满足集散功能的城市次干路交叉口低配形式。另外,亦对不同类型次干路车道功能的划分提出了建设性的意见和建议。

Optimization Design of Lanes\' Collection and Distribution Function at Minor Arterial Approaches Based on VISSIM
Abstract:In order to solve problems existing in the present operation and function positioning of urban minor arterials, their collection and distribution function are considered as the guide. Taking lane number and lane function divisions as studied objects, a function-oriented optimization design strategy of lanes' layout of minor arterial approaches is proposed. Based on the VISSIM simulation, the delay is used as an indicator to compare and analyze the ability of the two-way two-lane, two-way three-lane, and two-way four-lane roads to complete the collection and distribution function. Results show that the "two-way three-lane" is a low-allocation form of urban minor arterial intersections that can basically meet the collection and distribution function. It also provides constructive opinions and suggestions for the division of different types of minor arterial lanes.
