禁左管制下的交通排放系统模型与指标研究

Research on Traffic Emission System Model and Index in Left Turn Forbidden Situation

本文分析了影响尾气排放的各种因素,将尾气排放模型与交通工况模型结合起来,建立了多因子交通排放系统模型,对几种禁左绕行模式的工况构成、排放总量、影响范围、线性浓度、节点排量等主要指标进行比较分析,提出了各种模式的适用条件,为进行交通影响评价和禁左模式选择提供借鉴。

The paper analyzes various factor that influence automotive exhaust emissions, combines the emissions model and traffic operation condition model into a multifactorial emission system model. The paper compares several main index of each left turn forbidden detour mode such as work condition composing, total emissions amount, influence scope, linear density, node emissions quantity etc., and then puts forward appropriate conditions of each mode, in order to offer references for traffic influence evaluation and left turn forbidden choice.
