采用起迄点调查和交通量观测相结合的综合调查方法,了解项目区公路网交通运行实际情况。在遵循OD调查点和交通量观测站设置原则的基础上,扩大样本基数,生成基年OD数据,全面把握现有区域公路交通流向特性、交通运载特征、时间分布特征和出行分布特征。经验证发现,调查点覆盖全面,调查的数据能够全面掌握和分析项目影响区内的交通流量、流向、交通组成等公路交通特性。研究结果为交通量的分布、分配预测提供了可靠的基础数据。本文以楚雄至大姚高速公路为依托工点,将观测统计结果应用到实际工程中,为道路经济评价参数和工程建设指标的确定提供参考。
The comprehensive survey method combining the starting point and the point survey and the traffic volume observation is used to understand the actual situation of the road network traffic operation in the project area. Based on the principle of setting OD survey points and observatories of traffic volume, the sample base is expanded and the base year OD data is generated to comprehensively grasp the characteristics of traffic flow, traffic transportation, time distribution and travel distribution in the existing areas. It is verified that the survey points are comprehensive and the survey data can fully grasp and analyze the traffic characteristics such as traffic flow, flow direction and traffic composition in the project affected area. The results provide reliable basic data for traffic distribution and distribution forecasting. In this paper, Chuxiong to Dayao Expressway as the relying on the work site, the observation and statistics results are applied to the actual project for the road economic evaluation parameters and project construction indicators to provide a reference.
