Problems solved by technology

At this time, traffic congestion has already occurred, and it is impossible to prevent road congestion in advance
And because the traffic control personnel cannot understand the overall traffic situation, it may lead to more serious traffic congestion after traffic diversion

Embodiment 1

[0047] Embodiment 1 of the present invention provides an intelligent traffic control method, the step flow of the method can be as follows figure 1 shown, including:

[0048] Step 101, traffic signal lights determine traffic condition information.

[0049] In this embodiment, the traffic signal lights are equipped with sensing devices, such as dual cameras and / or other sensing devices, so that the traffic signal lights can be used to determine the traffic condition information at the intersection where they are located.

[0050] The traffic condition information is used to represent the traffic condition. For example, the traffic road condition information may include, but is not limited to, at least one of the following parameters:

[0051] Lane information, such as the number of lanes, lane type (left-turn lane, right-turn lane or right-turn lane), etc., number of vehicles, vehicle speed and vehicle queue length.

[0052] Step 102, the traffic lights report the traffic co...

Embodiment 2

[0074] Embodiment 2 of the present invention provides a method for an analysis server to obtain forecasted traffic information. The steps of the method can be as follows figure 2 shown, including:

[0075] Step 201, determine the current traffic flow information.

[0076] In this step, current traffic flow information in a specified direction between two intersections may be determined according to the received traffic condition information.

[0077] For example, the traffic flow information in a specified direction between two intersections can be determined according to the vehicle queuing length in each lane and the vehicle passing time between two intersections (ie, two traffic lights).

[0078] Step 202, determine the predicted traffic flow information.

[0079] In this step, the steering information of the vehicle can be determined according to the received traffic road condition information. For example, the steering information of a vehicle can be predicted accordin...

Embodiment 3

[0087] Embodiment 3 of the present invention provides a method for controlling traffic lights for designated vehicles. The steps of the method can be as follows Figure 4 shown, including:

[0088] Step 301, traffic lights determine whether there is a designated vehicle.

[0089] In this step, the traffic lights can detect whether the vehicle on each lane is a designated vehicle. Specifically, the information of the vehicle on each lane can be matched with the matching code stored in itself, and the information can be matched with the matching code stored in itself. The matched vehicle is determined as the designated vehicle. For example, an ambulance sign may be stored in a traffic signal light, and whether there is an ambulance is determined by matching the vehicle information on each lane with the ambulance sign.

[0090] If it is determined that there is a specified vehicle, then step 302 may be performed, otherwise, this step may be continued.

[0091] Step 302, the tr...

Abstract

An embodiment of the invention provides an intelligent traffic control system, device and method. Sensing equipment is assembled in traffic signal lamps, and the traffic signal lamps are used to determine traffic road condition information of a road where the traffic signal lamps are located. Traffic information of future time can be predicted by using the traffic road condition information determined by the traffic signal lamps, and the predicted traffic information is used to control operation of the traffic signal lamps. Though real-time control of an operation strategy of the traffic signal lamps, accurate control of traffic is realized, and occurrence of traffic jam is effectively prevented.

Description

technical field [0001] The present invention relates to the fields of communication and traffic, in particular to an intelligent traffic control system, device and method. Background technique [0002] With the rapid growth of the number of motor vehicles, urban traffic problems have become increasingly prominent. In the control of urban traffic, the following three solutions are generally used to solve the problem of traffic congestion: [0003] Option 1: Control traffic lights. [0004] The current traffic signal control technology, by referring to the road traffic congestion, sets the idle time period and busy time period according to experience, and according to the idle time period and busy time period, the red light, green light and yellow light duration of a traffic light cycle are calculated. Setting, so that the traffic lights operate according to the set time and program during the idle period and the busy period. [0005] Because traffic lights operate accordin...
