摘要: 面对城市交通拥堵严重,环境污染逐年加剧,本文利用车载尾气检测技术收集和比较了北京市典型信号协调路段与普通路段的实测尾气排放数据,分析了两种控制策略下的机动车尾气污染水平与分布规律;此外,结合微观交通仿真模型VISSIM和基于VSP变量的尾气排放建模方法,搭建了微观交通尾气仿真平台,通过实例仿真评价了不同信号配时和不同交通流量两种交通控制策略下的尾气排放。

Abstract: In response to the increased traffic congestion and worsened air pollution, using the portable emission measurement system (PEMS), this paper collects and compares the real world emissions under signal coordination and non-coordination in Beijing, and analyzes the emission levels and distribution characteristics under these two control strategies. Furthermore, by integrating the microscopic traffic simulation model of VISSIM and the VSP-based approach of emission modeling, the paper develops an integrated microscopic simulation platform of traffic emissions, which is finally used to evaluate the impact of two traffic control strategies, alternative signal timing and traffic flow on emissions.

Key words: signal coordination, portable emissions measurement system (PEMS), emission modeling, microscopic traffic simulation, emission factor
