Intelligent transportation system based on networked communication technology and control method thereof

Abstract

The invention discloses an intelligent transportation system based on a networked communication technology. The intelligent transportation system comprises a traffic signal light, a traffic signal light controller, a camera system, a regional traffic control center, a cloud platform, a portable networkable device and a vehicle-mounted networked communication device. According to the intelligent transportation system based on the networked communication technology and a control method thereof, the best travel route can be selected, so that a traffic congestion road section is avoided; and a reasonable vehicle speed is selected to pass an intersection to avoid the red light so as to shorten the time for waiting for the red light and the time of slow travelling during traffic jams, and the fuel consumption is reduced. The intelligent transportation system has small manual intervention workloads and low costs in the case of real-time traffic flexibility.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to an intelligent transportation system based on networking communication technology. Background technique [0002] With the improvement of people's living standards, cars have entered ordinary families, followed by traffic jams in cities and increased fuel consumption of cars caused by traffic jams. At present, when people travel by car, they need to spend a lot of time waiting for red lights and dealing with traffic jams. Therefore, choosing the best travel route to avoid traffic jams and choosing a reasonable speed to avoid red lights at intersections has become the current solution. The best solution to traffic jams. [0003] At present, domestic traffic light control is mainly divided into two types: timing distribution method and monitoring room control method. The timing distribution method requires simple equipment and less investment, but the traffic control flexi...

AI Technical Summary

Problems solved by technology

[0003] At present, domestic traffic light control is mainly divided into two types: timing distribution method and monitoring room control method. The timing distribution method requires simple equipment and less investment, but the traffic control flexibility is poor.

In some cases, there is no vehicle passing through the transverse lane at the intersection, and the driver in this lane has to wait for the red light, which increases the waiting time for the driver and increases the fuel consumption of the vehicle

Traffic lights can be controlled through the monitoring room, which can be flexible enough according to real-time traffic, but the workload of manual intervention is heavy and the cost is high

[0004] Patent Publication No. US6317058B1 analyzes real-time traffic jams and reasonably controls traffic lights through vehicle GPS positioning technology and video detection means. This patent does not consider the impact of weak GPS signals and positioning errors on the system in cities

The patent of Publication No. CN205582271U controls the time delay of traffic lights at intersections by monitoring the flow of vehicles and people in real time, and switches between different modes according to actual conditions. Save the existing data, do not analyze it, and do not get the traffic pattern of the city in this time period

The patent of Publication No. CN103236163B exploits hotspots to avoid traffic congestion, but this patent does not take into account that the number of hotspots is not linearly related to vehicle road congestion. Although it can reflect that there are many people active in the relevant area, it cannot be directly judged that the place is in traffic congestion. Congestion
