城市信号交叉口交通调查方法的改进

Improvement of Traffic Survey Methods of Urban Signalized Intersections

针对城市信号控制交叉口,从实地调查的角度出发,给出了同一时间测量同一交叉口的交通量、通行能力、延误指标的综合调查与整理分析方法,不仅节约了大量人力物力,也最大限度的保证了观测数据的精确性,并用实例验证了其可行性。此方法是交通工程专业交通调查课程实习的实践成果,具有较强的实用性和可操作性。

Aiming at urban signalized intersections, from the view of field survey, a comprehensive survey and arrangement analysis method of measuring traffic flow parameters of volume, capacity and delay is given. It can save a lot of human and material resources and ensure the accuracy of observation data in a maximum extent, and the feasibility is verified by an example. This method is practical achievements of traffic survey course practice of specialty in traffic engi- neering, and it has strong practicability and operability.
