城市道路交通运行指数的对比和思考

A Study on Road Traffic Performance Index

中国主要城市通过道路交通运行指数及时评价当前道路运行情况,并在交通管理、公众出行服务等方面发挥了重要作用。首先,总结交通拥堵和道路交通运行指数的内涵,梳理主要城市道路交通运行指数的差异。其次,从基础数据采集不全面、指标评价分析不系统等方面分析交通运行指数评估的不足。最后,从完善交通评估模型、建立交通运行指数预测模型和发布机制、新技术应用促进数据采集更全面和指数评估更科学、系统构建交通运行综合指数等方面提出对策,为今后道路交通运行评估提供启示。

In recent years, using road traffic performance index turns to be ever-increasing popular in Chinese cities, in which it is adopted to assist in decision-making in traffic management and public travel services. This paper first summarizes the essence of traffic congestion and traffic performance index, as well as the difference of various types of traffic performance index. The paper then discusses a number of critical limitations about the existing traffic performance index, including raw data collection and indicator selection process. Finally, the paper provides corresponding improvements: 1) enhance traffic assessment model;2) develop forecasting model and publication mechanism;3) strength data collection technology;and 4) propose a synthesized traffic performance index.
