Abstract

The invention relates to the technical field of traffic planning and in particular to a method and device for allocating a traffic flow in a highway. The method comprises: obtaining highway toll gateinformation and highway interconnected node information; obtaining reaching relations and distances between highway toll gates, between highway interconnected nodes, and between a highway toll gate and a highway interconnected node; obtaining highway toll data and calculating an OD traffic flow between highway toll gates; according to a reaching relation matrix and distances between the highway toll gates, between the highway interconnected nodes, and between the highway toll gate and the highway interconnected node, allocating the OD traffic flow between the highway toll gates to the road sections between the highway toll gates, between the highway interconnected nodes, and between the highway toll gate and the highway interconnected node by using a preset algorithm so as to effectively solve the traffic flow allocation problem of the national highway toll data at a level of tens of billions.

Description

technical field [0001] The invention relates to the technical field of traffic planning, in particular to a method and device for traffic flow allocation on expressways. Background technique [0002] Traffic volume forecasting is an important link in the road planning and design process. Generally, a four-stage method is adopted. Traffic volume allocation is a crucial stage, which is used to reflect the matching relationship between road network scale and traffic demand. Usually, people will prepare corresponding road network data and OD traffic volume data for traffic allocation according to the data format requirements of commercial software such as TransCAD and Emme. [0003] The inventor found through research that it is difficult to obtain accurate national expressway network data and toll data when using commercial software to allocate traffic flow on expressways, which leads to inaccurate traffic flow allocation on expressways. Therefore, it is a technical problem to...
