公路交通服务能力的绿色安全指标研究

摘要/Abstract

摘要：

国际上公路交通服务能力皆以道路拥堵情况(V/C 值)及行车顺畅程度为评估标准，缺乏对交通安全潜在社会成本、时间成本及环境保护的测量.根据国际社会对绿色经济、绿色交通运输的重视与发展趋势，本文以台湾电子收费系统的数据为基础，针对不同交通流需求量、路段平均行驶速率衍生的时间成本与污染排放、交通安全等因子，分别构建出行时间延滞成本、碳排放增量成本、潜在肇事概率成本等3 个参数指标，利用这3 个指标构建综合型绿色安全交通服务指标(Green and Safety Index for traffic levels of service, GSI)，作为划分交通服务水平的评估标准，并通过实时在线软件，提供出行者道路出行延滞、碳排放及安全等社会成本信息.

关键词: 综合交通运输, 绿色交通指标, 延滞成本指标, 碳排放增量成本指标, 安全成本指标

Abstract:

Traffic level of services (LOS) on the volume- to- capacity (V/C) ratio is commonly utilized worldwide institutions. However, it lacks the comprehensive concept of time cost, environmental protection, and potential social cost of traffic safety. Based on international concentrations of green economy and transport, this paper establishes three indicators, cost of potential accidents, cost of travel delay, and cost of incremental carbon emissions by using Taiwan freeway ETC online data, in terms of different traffic volumes and travel speeds, namely time cost, pollution, and traffic safety, then later aggregates to a green and safety index for evaluating a certain road segment level of service (Green and Safety Index for traffic levels of service, GSI). This is able to apply to an online APP, providing real- time such messages as travel delay, carbon emission, and traffic safety externally social costs for road users.

Key words: integrated transportation, green and safety index for traffic levels of service (GSI), travel delay cost indicator, incremental carbon emissions cost indicator, safety cost indicator
