Traffic-monitoring-data-based traffic capacity mining method of road section

Abstract

The invention, which belongs to the technical fields of traffic data mining and application, provides a traffic-monitoring-data-based traffic capacity mining method of a road section. The method comprises: step one, acquiring traffic monitoring data of a designated research area of a city and a road section range requiring traffic capacity mining; step two, screening vehicle traffic data passing atarget road section, carrying out statistics based on vehicle models, and calculating an equivalent car conversion coefficient; step three, carrying out classification on monitoring data by using a day as a unit, carrying out lognormal distribution fitting to obtain a saturated vehicle head time interval of the road section, and calculating a single-day equivalent traffic capacity of the road section; and step four, calculating an average value of all-day traffic capacities of the road section in the research area and using the result as a motor vehicle traffic capacity of the road section. According to the invention, the traffic-monitoring-data-based traffic capacity mining method having advantages of simple steps, high calculation efficiency, and accurate result has the important practical significance in calibrating basic parameters of the road section in urban transportation system simulation and provides a powerful technical support for construction of an urban virtual transportation system test platform.

Description

technical field [0001] The invention relates to the technical field of traffic data mining and application, in particular to a road section capacity mining method based on traffic monitoring data. Background technique [0002] In recent years, with the rapid development of modern information technology, transportation has entered the era of "Internet + big data". Traffic is the artery of urban economic development. With the rapid development of economy and society and the acceleration of urbanization, urban traffic problems such as traffic congestion are becoming more and more serious. In order to alleviate various problems in urban traffic, based on the guidelines of "Internet + Traffic", many cities have established real-time monitoring systems for traffic flow. Provide scientific data support. [0003] In the process of intelligent transportation construction and operation, the amount of data generated every day by video surveillance, checkpoint electric police, road co...

Problems solved by technology

Although this calculation method is simple and easy to operate, due to the strong subjectivity of the selection of some correction coefficients, there may be repeated corrections between different correction coefficients. Obviously, the accuracy of the existing calculation method is difficult to be guaranteed. Therefore, the present invention proposes A Method of Mining Traffic Capacity of Road Sections Based on Traffic Monitoring Data
