A method for evaluating the operation status of regional expressway network

Abstract

The invention discloses a method for evaluating the running state of a regional high-speed road network, which is realized through the following steps: step 1: divide the road section of the high-speed road network; step 2: obtain the evaluation of the micro-traffic running state of the expressway sub-road section; step 3: obtain the expressway Road section mesoscopic traffic operation state evaluation; Step 4: obtain the macro-traffic operation state evaluation of the high-speed road network based on the road network structure; Step 5: obtain the expressway road network traffic travel index; The judgment of the speed and threshold of each section of the highway determines the congestion degree of each section, and then determines the traffic congestion index of the road network by calculating the ratio of the congestion mileage to the total mileage of the road network. This index is a macro index for evaluating the regional expressway network and can intuitively reflect The operating status of the regional expressway network provides a dynamic travel index for traffic managers and traffic travelers.

Description

technical field [0001] The invention relates to a method for evaluating the running state of a high-speed road network, which is an evaluation method for evaluating the traffic running state of the high-speed road network by using a single index. Background technique [0002] In recent years, my country's expressway construction has developed rapidly, but at the same time, there are still problems such as traffic safety, traffic efficiency, and environmental pollution during operation, especially during holidays and morning and evening peak periods. The evaluation index of expressway network operation status can intuitively and dynamically reflect the operation status of expressway network, provide important traffic information reference for traffic travelers, and play a key role in the effective management and operation of expressways, and the full play and coordination of expressway network traffic capacity. effect. [0003] At present, the urban road network traffic stat...
