本文在充分考虑杭州市城市交通流特性的基础上,提出了一种机动车通行效率评价方法,包含路段通行效率评价和交叉口通行效率评价两类。其中,路段通行效率通过单位时间网络交通流中所有车辆行驶的总里程来表征,交叉口通行效率通过延误和排队强度来表征,上述指标主要面向交通管理者提供决策支持信息。最后,以杭州市主城区重点区域(含16个交叉口,约50条路段)为例,计算相关路段及交叉口通行效率,并分析该区域交通运行规律及交通管控方向。
Based on the full consideration of the characteristics of urban traffic flow in Hangzhou, this paper presents a method to evaluate the traffic efficiency of vehicles, which includes the evaluation of road traffic efficiency and the evaluation of traffic efficiency at intersections. Among them, the efficiency of road sections is represented by the total mileage of all the vehicles in the network traffic flow per unit time, and the traffic efficiency of intersections is characterized by the delay and queuing strength. The above indexes mainly provide the traffic managers with decision support information. Finally, taking the key urban area of Hangzhou (including 16 intersections and about 50 road sections) as an example, the traffic efficiency of relevant road sections and intersections is calculated and the traffic operation rules and traffic control directions are analyzed.
