为评估城市干路交通拥堵导致的经济、环境成本和公众利益损失及其对区域架构的影响,设计了一种定量与定性相结合的分析方法。给出了因交通拥堵产生的八类损失,包括:出行时间损失、燃油损失及车辆损耗、交通事故损失、噪声损失及尾气排放增加的损失等五类从经济或环境、技术角度可量化的损失,以及交通拥堵导致机构搬迁对当地经济的影响、危险品运输风险增加导致的公众利益损失和交通拥堵阻隔效应等三类不可量化的损失。对于可量化的损失,对比拥堵和非拥堵情况下的费用成本,将有助于决策者从公众利益角度构建更为高效的交通系统。
In order to assess the economic, environmental costs and public interest losses caused by traffic congestion in urban trunk roads and their impact on the regional structure, a quantitative and qualitative analysis method is designed. Eight types of losses due to traffic jams are given, including: loss of travel time, loss of fuel and vehicles, loss of traffic accidents, loss of noise and loss of increased emission of exhaust gases. Five kinds of economic, environmental and technical quantifiable losses , As well as three kinds of unquantifiable losses caused by the impact of relocation of agencies on the local economy due to traffic congestion, the loss of public interest resulting from the increased risk of dangerous goods transport, and the traffic congestion blocking effect. For quantifiable losses, comparing cost costs in congestion and non-congestion situations will help policymakers build more efficient transport systems in the public interest.
