Embodiment Construction

[0046] In order to describe the technical content of the present invention more clearly, further description will be given below in conjunction with specific embodiments.

[0047] Such as figure 1 As shown, in one embodiment, the method for realizing traffic road condition assessment analysis based on computer software system of the present invention comprises the following steps:

[0048] (1) The system collects the traffic flow data of the corresponding road section to obtain the current period average vehicle speed of the road section;

[0049] (2) described system calculates and obtains corresponding traffic jam index according to following formula:

[0050] TPI L =10·(1-V / V f );

[0051] Among them, TPI L is the traffic congestion index, V is the current cycle average speed of the section, V f is the free-flow speed of the road segment;

[0052] (3) The system analyzes the traffic condition of the road section according to the traffic congestion index.

Abstract

The invention relates to a method for realizing traffic condition assessment and analysis based on a computer software system. The method includes the following steps that: a system acquires traffic flow data of a corresponding road section so as to obtain the average vehicle speed of the road section in a current period; the system calculates a corresponding traffic congestion index according to the average vehicle speed in the current period; and the system analyzes the traffic condition of the road section according to the traffic congestion index. In addition, the invention also relates to a system for realizing traffic condition assessment and analysis based on a computer software system by using the above method. The system for realizing the traffic condition assessment and analysis based on the computer software system includes a flow acquisition module, a flow data processing module and a traffic congestion index database. With the method and the system for realizing the traffic condition assessment and analysis based on the computer software system provided by the invention adopted, a traffic condition can be quantified, the efficiency of evaluation analysis and the accuracy of data required by the evaluation analysis can be improved, an analysis result is more reasonable and intuitive, and analysis on an overall traffic condition and remote control on later-stage intelligent traffic can benefitted. The method and the system have a wider application range.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, in particular to the field of intelligent transportation evaluation and analysis, and specifically refers to a method and system for realizing evaluation and analysis of traffic road conditions based on a computer software system. Background technique [0002] With the continuous aggravation of urban traffic congestion, various cities have begun to use high-tech means to help alleviate traffic congestion and ensure traffic safety. One way is to use certain algorithms to evaluate the traffic conditions through the collected road traffic flow data, and divide the road traffic status into three categories, namely smooth, congested and blocked. Then through the information release system, the real-time road conditions of the urban road network are released to the public in real time, so that traffic participants can be reminded in time, reducing the probability of traffic j...
