Embodiment 1

[0037] In order to realize the accurate prediction of expressway traffic operation status and provide traffic control and guidance decision-making and support for the traffic management part, this embodiment provides a scheme of expressway traffic time map system, by integrating the monitoring points of the current expressway network Video data and toll station traffic data realize the prediction of traffic conditions in the future forecast time, and load the forecast information onto the expressway network to form a highway traffic time map. The expressway traffic time map refers to the traffic conditions presented on the road network over time Based on the time map, the background management personnel of the traffic management department can intuitively know the distribution of traffic flow in the future forecast time, so as to make timely warnings and control plans to alleviate traffic congestion and improve the processing efficiency of abnormal events. Realize smart transpo...

Embodiment 2

[0092] In the embodiment On the basis of the first embodiment above, a method for constructing a freeway traffic time map is provided, please refer to Figure 4 , the method mainly includes the following steps:

[0093] S401. Set an initial observation time point t0, a rolling forecast period T, and a forecast time t.

[0094] S402. According to the rolling forecast period T, obtain the vehicles currently entering the station from each toll station from the toll station supervision subsystem as the first vehicle to be tested, and obtain the second average value matching the model and driving direction of the first vehicle to be tested speed, and use the matched second average speed as the first target speed V1.

[0095]Optionally, obtain the latest historical passage record of the first vehicle to be tested passing through the toll station, if the latest historical passage record is the toll station as the entry station, then use the last historical passage record as the exit...

Abstract

The invention provides a highway traffic time map construction method and a highway traffic time map construction system based on fusion data. According to the highway traffic time map construction method and the highway traffic time map construction system, traffic condition of a highway is predicted according to highway traffic data (video monitoring data and toll gate passing data), the utilization rate of the highway traffic data is mined and maximally increased, and the continuity of the traffic flow is fully considered, thereby being conducive to improving the accuracy of forecasting; inaddition, the traffic development trend is the decision-making basis for traffic manager to implement management and control, can help the traffic management department to make decisions scientifically, actively and intelligently, and is conducive to realizing intelligent transportation.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and a system for constructing a highway traffic time map based on fusion data. Background technique [0002] By the end of 2017, my country's expressways had reached 136,500 kilometers, ranking first in the world, accounting for half of the global expressway mileage. The construction of expressway infrastructure has played a vital leading, basic supporting role and service effect in promoting my country's social and economic development. [0003] The intelligentization and informatization of expressways in my country have been vigorously constructed and are still going on. It is estimated that the market size will be close to 90 billion yuan by 2023. The two main subsystems of the expressway intelligent system are: intelligent toll collection system and security monitoring system. According to incomplete statistics, road supervisors and business depa...
