基于交通噪声与延误的平面交叉口综合评价

从噪声影响的角度出发，将噪声和延误结合起来对平面交叉口进行综合的评价研究．通过在微观交通仿真软件上加载插件，建立了交叉口交通噪声及延误的计算模型，并用实测数据进行验证．在此基础上，研究信号控制交叉口、环形交叉口、无控制交叉口内车流量与延误、车流量与噪声间的关系，并将延误和噪声采用经济损失估算方法进行统一换算，实现不同流量、不同控制方式下平面交叉口的综合评价．

Comprehensive Evaluation of Intersection Based on Traffic Noise and Delays

From the view of noise impact, the intersection is evaluated comprehensively by combining traffic noise and delay. By loading plugin in microscopic traffic simulation software the computational models of traffic noise and delays are developed, and some measured data are used to verify the mod- els. On this basis, the relationships between volume and delays, and volume and noise under the con- ditions of the signal intersection, roundabout and uncontrolled intersection are investigated. Then the comprehensive evaluation of the various ways of management in intersection under different traffic flows is realized by calculating the economic losses caused by the delays and noise.
