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 present disclosure provides a modeling method for traffic flow in a service area of ​​an expressway, which includes: collecting the number of vehicles entering a certain service area for several days, calculating the change curve of traffic flow in the service area for each day and clustering it , to obtain the change pattern of vehicle inflow in multiple service areas; use the Gaussian mixture model to fit the time distribution of vehicle inflow in different service areas, and obtain the inflow model of multiple service areas; according to the main line near the service area The cross-sectional traffic volume, service area scale, distance between the service area and the front and rear service areas or cities are used to construct the inflow volume model of the service area, and a service area inflow traffic flow model with the individual characteristics of each service area is obtained.

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...
