Abstract

The invention discloses an evaluation method for regional traffic accessibility based on traffic big data. The evaluation method includes: (1) determining the boundary of the evaluation area and the number of concentrated areas to be evaluated; (2) determining the boundary of the peripheral area and the number of concentrated areas participating in the evaluation; (3) grid processing for all selected concentrated areas; (4) setting the weight coefficient of the grid; (5) setting the evaluation operation parameters; (6) collecting Travel time data; (7) Screen and process the travel time data; (8) Calculate the regional traffic accessibility level of each grid and each concentrated area in the evaluation area according to the data in step (7). According to the evaluation method of regional traffic accessibility based on traffic big data of the present invention, it can take into account the accuracy and calculation efficiency of evaluation or estimation, and can help to efficiently, comprehensively and consistently evaluate regional traffic accessibility in different regions Evaluation or research to help make better public decisions.

Description

technical field [0001] The invention relates to the comparison and evaluation of regional traffic accessibility in different regions within a region, in particular to a method for evaluating regional traffic accessibility based on traffic big data. Background technique [0002] Regional transportation is a comprehensive transportation system that transports within a wide range of townships, counties, cities, provinces and the whole country. In the past, the accessibility evaluation of regional traffic was more of a large-scale evaluation between cities, based on the travel time of large traffic, without considering or roughly considering the time within the city. For example, for railways, the time between cities is the time from the train station to the train, plus at most the average time from a key area within the city to the train station; for expressways, the time between cities is the time from the toll station to the toll The time at the station, plus the average tim...
