Abstract

Abstract: The paper regards the model of roundabout as the research object, investigates its traffic volume of rush hour, basing on Wardrop formula that is a calculation method of interweave traffic capacity. Its guidance idea is that bottle-neck interweave capacity determine capacity of the whole roundabout. It puts forward restrained interweave section volume method of calculating traffic capacity of the whole roundabout. By investigating traffic volume of Erqi Plaza in Dalian and calculate its traffic capacity.

Key words: roundabout, capacity, wardrop equation, restrained interweave section volume method

摘要： 以环形交叉口为研究对象，调查其高峰小时交通量，并以交织段的通行能力测算方法——沃尔卓普公式为基础，以瓶颈交织段的通行能力决定整个环形交叉口通行能力为整体思想，提出计算环形交叉口通行能力的新方法——交织段流量限制法，并对大连市二七广场环形交叉口作了交通调查及通行能力计算。

关键词: 环形交叉口, 通行能力, 沃尔卓普公式, 交织段流量限制法
