A User-Oriented Expressway Traffic Index Publishing System

Abstract

The invention discloses a user-oriented highway traffic index publishing system comprising a traffic data acquisition module and a traffic index division module, determination module and publishing module. The traffic index division module constructs a traffic flow fundamental diagram to perform traffic state grade division according to the historical traffic flow rate and speed data and then converts the division result into the traffic index grade and determines the traffic density critical threshold of different levels of traffic index values of the same index grade. The traffic index determination module performs traffic state and traffic index grade division on the traffic flow rate and speed data acquired by the traffic data acquisition module and determines the concrete traffic index value. The traffic index publishing module publishes the traffic index grade information in real time. According to the constructed user-oriented highway traffic index publishing system, the practical application of the traffic index system and application technology on the highway is supported so that the safe, smooth and high-quality highway traveling service is provided for travelers.

Description

technical field [0001] The invention relates to the field of expressway operation management, in particular to a user-oriented expressway traffic index release 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 a research hotsp...

Problems solved by technology

However, only some scholars use multi-indicators and clustering algorithms to quantify the traffic status of expressways, but the relevant indicators and clustering algorithms have not been fully applied to the expressway traffic index.

Moreover, almost no scholars have discussed the research and application of the expressway traffic index system, and it is particularly important to further master the study of expressway traffic status.
