Abstract

The invention discloses a traffic circulation index building method with the consideration to the characteristics of an urban road traffic network, and the method comprises the following steps: S1, constructing an urban road network model; S2, calculating an influence factor; S3, calculating traffic state values of road segments; S4, calculating a weighting factor of each road segment; S5, calculating a density level coefficient of an area; S6, calculating a traffic circulation index value of the area; S7, evaluating the urban traffic state based on the traffic circulation index value; According to the invention, the road level, regional road network density, traffic node accessibility and connectivity of the urban road traffic network are introduced to an urban traffic circulation evaluation model, thereby solving a problem of the evaluation of the comprehensive circulation conditions of the urban traffic caused by the increasingly complex urban road network and the quick developmentof traffic.

Description

technical field [0001] The invention relates to a method for establishing a traffic operation index, in particular to a method for establishing a traffic operation index in consideration of the characteristics of an urban road traffic network. Background technique [0002] The urbanization process and the rapid development of traffic demand have caused urban traffic congestion to become increasingly serious. Congestion not only causes huge time loss, but also causes various environmental and economic problems. It has become one of the problems that large and medium-sized cities at home and abroad urgently need to solve. The urban traffic network is a comprehensive, dynamic, and open complex system. In order to reasonably evaluate the urban traffic operation status, it is necessary to establish scientific evaluation indicators and methods for the traffic system. Measures and the technical basis to guide citizens to travel reasonably are also the key to solving the problem of ...
