Abstract

The invention discloses a method and device for determining an urban traffic operation state, relates to the technical field of road traffic, and mainly aims to determine the overall traffic operationstate of a city by determining traffic operation indexes in multiple different dimensions. According to the main technical scheme, the method comprises the steps of obtaining road section informationof each road section in a target city and a corresponding road section passing speed; based on a plurality of target dimensions, counting the road section information and the road section passing speed to acquire a plurality of traffic state indexes corresponding to each road section, and the target dimensions at least comprising a time dimension and a space dimension; and determining corresponding traffic operation indexes of the target city in a plurality of target dimensions according to the plurality of traffic state indexes corresponding to each road section.

Description

technical field [0001] The invention relates to the technical field of road traffic, in particular to a method and device for determining the running state of urban traffic. Background technique [0002] With the continuous expansion of urban scale, the problem of urban traffic congestion is becoming more and more serious, which has a huge impact on people's work and life. The causes of urban traffic congestion involve various issues such as economic development, transportation methods, traffic habits, and road network. The characteristics of operation can be used to evaluate the overall state of urban traffic operation. [0003] At present, the method to evaluate the state of urban traffic operation, especially the state of urban traffic congestion, is mainly based on the traffic speed of the road section and the weight of the road section. The ratio of travel time in the flow state, and then use the weight values ​​corresponding to different road sections to count the ov...
