Problems solved by technology

However, as far as the inventor knows, the existing research on expressway service areas only stays at the service area entry rate at a single time point, and does not consider the service area entry rate over time.

Abstract

The invention provides a highway service area driving-in traffic flow modeling method, which comprises the following steps: collecting the driving-in quantity of vehiclesin a certain service area formultiple days, calculating the driving-in traffic flow change curve of the vehicles in the service area every day, and clustering the driving-in traffic flow change curve to obtain a plurality of service area driving-in traffic flow change modes; fitting the service area vehicle driving-in time distributions of different driving-in traffic flow change modes by utilizing a Gaussian mixture model toobtain driving-in quantity models of a plurality of service areas; according to the main line section traffic volume near the service area, the service area scale, and the distance between the service area and the front and rear service areas or cities, carrying out sample expansion construction on the service area driving-in quantity model to obtain a service area driving-in traffic flow model with individual characteristics of each service area.

Description

technical field [0001] The present disclosure relates to the field of traffic planning data analysis, and in particular to a modeling method for traffic flow in a service area of ​​an expressway. Background technique [0002] In intercity traffic, the expressway service area is a very important rest area. It provides a variety of services for traveling users. Reasonable expressway service area planning and operation can provide more convenience for passengers. Create greater profits. A very important factor to measure the operation effect of the service area is the change of the inbound traffic flow in the service area in a day. Too much inbound traffic will cause the service area to be overloaded, and too little inbound traffic will lead to waste of resources. Understanding the change pattern of incoming traffic flow in the service area can analyze the reasons for the change in incoming traffic flow, predict the subsequent change in traffic flow, and provide an important r...
