| 摘 要： | 从交通拥挤外部成本、交通事故外部成本、空气污染成本及噪声成本4个方面,定量计算交通出行对于道路使用者、非道路使用者及社会环境的负外部性影响. 以北京市东三环主路为例,计算全天各时段的交通出行外部成本,并分析其变化特征. 结果表明,拥挤外部成本对总外部成本的贡献率最大,且随着流量增加,路段平均车速降低,呈现迅速上升趋势.

| Abstract: | In the paper, the external cost of urban expressway transportation was analyzed quantitatively by four aspects, including traffic congestion external cost, traffic accident external cost, air pollution cost and noise cost. Besides, the main road of the 3rd east ring expressway in Beijing is taken as an example to conduct the calculation of transport external cost according to different time period. In addition, the variation of transport external cost during different time periods in a day was analyzed in the paper. It was found that congestion external cost takes up the largest part of total external cost. With the increase of traffic volume and decrease of average speed, congestion external cost rises sharply. |
