Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that in the prior art, only a single road condition characteristic parameter is used to predict future road conditions in combination with historical road conditions. Since the current road condition characteristics cannot be comprehensively reflected, the accuracy of future road condition prediction is affected. , so as to propose a traffic condition prediction system and method that integrates various information of current traffic condition

Embodiment 2

[0095] (1) Work to be done before: In terms of program, the architecture process must be planned and laid out;

[0096] (2) Traffic flow object configuration work: the configuration of roads, equipment, intersections, road sections, and directions, as well as the equipment lanes to be predicted to lead the way, etc. must be associated.

[0097] (3) Algorithm configuration: According to the method in Embodiment 1, the algorithm in each level of detection unit is set, and the percentage of each algorithm is set.

[0098] Such as image 3 As shown, the road Zhongshan Avenue is set up; 2 intersections Qiaokou Road and Chongren Road; 1 road section S1 Zhongshan Avenue_Qiaokou Road_Chongren Road, and the associated equipment signal detector is set on the road section, including 3 Lanes (D1-1, D1-2, D1-3 on the lower left); set the road section to be predicted, the percentage of traffic levels, and use the above traffic condition prediction system to make a good prediction of future...

Abstract

The invention discloses a traffic condition prediction system fused with various transport data and a method. The traffic condition prediction system comprises a flow level detecting unit, a speed level detecting unit, a flow trafficability ratio level detecting unit, a flow occupancy level detecting unit, a speed occupancy level detecting unit, a saturation coefficient level detecting unit, a historical road level detecting unit and a road condition predicting unit, level numbers of parameters are obtained by the various level detecting units by means of measuring and computing, then the level numbers are multiplied by percentages of level numbers of the parameters preset in the road condition predicting unit, the sum of the products is computed to obtain road condition level numbers, and a road condition within future prediction time is obtained according to a road condition corresponding to preset road condition level numbers. The technical problem that a future road condition is predicted by means of combining a single road condition characteristic parameter with a historical road condition in the prior art. The traffic condition prediction system and the method are fused with various information of a current road condition.

Description

technical field [0001] The invention relates to a system and method for predicting traffic conditions, in particular to a system and method for predicting traffic conditions by fusion of multi-source heterogeneous traffic data. Background technique [0002] With the improvement of people's material living standards, the number of motor vehicles is increasing, and the roads are becoming more and more congested. If people can keep abreast of the current road traffic situation and the development of future road conditions, the traffic capacity of the road can be greatly improved, time can be saved for people, and the utilization rate of resources can be improved. [0003] Currently, there are various ways of judging road conditions, which are mainly divided into two types, that is, automatic detection and reporting by hardware equipment and manual reporting. Manual observation reports are fast and accurate, but for complex traffic routes in large cities, it is impossible to ma...
