A Manager-Oriented Expressway Traffic Index Prediction Method and System

Abstract

The invention discloses a manager-oriented highway traffic index prediction method and a system thereof. The method comprises the steps of acquiring the traffic data of a highway and constructing a historical database; constructing a basic highway traffic flow map; dividing the traffic states of the highway into different grades through the clustering process and correspondingly converting traffic state grades into traffic index grades; determining a specific traffic index grade corresponding to each data point; predicting the traffic flow rate and the speed value of a next sampling interval through the k-nearest neighbor method; calculating the distance between the predicted value and the clustering center of each traffic state, and determining the traffic state type thereof so as to further obtain a corresponding traffic index grade; issuing the predicted traffic index grade to managers. According to the technical scheme of the invention, a manager-oriented highway traffic index prediction system is constructed, so that the practical application of a traffic index system and the application technique thereof on the highway is realized. Therefore, managers can formulate corresponding management measures in advance. Meanwhile, the high-quality highway travel service is provided for travelers.

Description

technical field

[0001] The invention relates to the field of expressway operation evaluation, in particular to a manager-oriented expressway traffic index prediction method and system. Background technique

[0002] In recent years, the construction and operation of my country's expressways are in a stage of rapid development, and the traffic volume of expressways is also increasing year by year. Especially during holidays, expressway congestion is prone to occur. Expressway managers are currently facing challenges brought about by the contradiction between traffic supply and demand. How to intuitively and timely understand the traffic operation status on the expressway, and on this basis, scientifically control the entrance and exit of the expressway, has become a solution to the traffic supply and demand problem, and for The key to providing better service to highway users and easing highway congestion.

[0003] In recent years, the concept of road traffic index has become...

Examples

Embodiment Construction

[0028] Below in conjunction with specific embodiment, further illustrate the present invention, should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention, after having read the present invention, those skilled in the art will understand various equivalent forms of the present invention All modifications fall within the scope defined by the appended claims of the present application.

[0029] Such as figure 1 As shown, a manager-oriented expressway traffic index prediction method disclosed in the embodiment of the present invention includes the following steps:

[0030] (1) Collect the traffic flow rate and speed data of the expressway, and construct the historical database of the expressway. Expressways rely on fixed detection equipment deployed along the entire line to collect relatively high-precision data such as flow, speed, and occupancy. Only using any single data index ...
