Problems solved by technology

[0004] The purpose of the present invention is to provide a road traffic control system, which is used to alleviate road congestion and avoid the lane that needs to continue along the main road from being occupied due to road congestion in the direction of travel from the main road to the branch road. The problem

Embodiment 1

[0037] figure 2 It is a schematic diagram of the road traffic control system in Embodiment 1 of the present invention, image 3 It is a road schematic diagram of a control system with road traffic in the first implementation of the present invention.

[0038] specific reference image 3 As shown, the road includes a main road 21 and a branch road 22, and the main road 21 is divided into at least two lanes in the same direction by a dividing line on the road surface. In this embodiment, the trunk road 21 is divided into two lanes by a dividing line, namely a first lane 21 a and a second lane 21 b, wherein the first lane 21 a is close to the branch road 22 .

[0039] Further, the main road 21 is, for example, an expressway, and the branch road 22 is, for example, an off-ramp of the expressway. Or, the road can also be a city road, the main road 21 is, for example, the main road of the city road, and the branch road 22 is, for example, an auxiliary road of the city road, or t...

Embodiment 2

[0105] The difference from Embodiment 1 is that the road traffic control system and its control method in this embodiment can also be applied to roads with more than two lanes in the same direction on the main road.

[0106] Figure 6 It is a road schematic diagram of the control system with road traffic in Embodiment 2 of the present invention. Such as Figure 6 As shown, the main road 21 is divided into n lanes in the same direction by the dividing line on the road surface, and the n is a positive integer greater than or equal to 2. In this embodiment, four lanes in the same direction are shown.

[0107] And, in the road traffic control system of this embodiment, the information generation module 13 can also be used to convert the length value of the generated solid line segment (that is, the theoretical length value L of the solid line segment S1 ) is further compared with a length threshold Lx.

[0108] When the length value of the solid line segment (that is, the theo...

Abstract

The invention provides a road traffic control system and a control method thereof. The corresponding speed limit information can be obtained by detecting the traffic inflow speed upstream of the road and the outflow speed of traffic downstream on the road, and comparing the difference between the inflow speed of the traffic flow and the outflow speed of the traffic flow, and the speed limit information can also be prompted to the upstream vehicle. When there is a congestion, the upstream vehicle can slow down in time and change lanes according to the demand, so as to avoid a large number of vehicles that need to turn to the branch road to be congested at the entrance of the branch road, thereby preventing other lanes from being occupied and ensuring Other lanes can still be used unimpeded.

Description

technical field [0001] The invention relates to the technical field of traffic control, in particular to a road traffic control system and a control method thereof. Background technique [0002] With the rapid increase in the construction mileage of expressways in my country and the rapid growth of motor vehicle ownership, expressway traffic demand and traffic volume have increased sharply, increasing the pressure on expressway traffic, and the traffic capacity of some sections of the expressway network has been unable to meet the existing requirements. need. Especially during peak traffic hours, when the traffic demand of the expressway is greater than the traffic capacity, it leads to frequent traffic congestion on the expressway, which not only reduces the efficiency of expressway traffic, but also increases the conflict and friction between vehicles. [0003] For example, at the ramp position of the expressway, limited by the capacity of the ramp, traffic jams are often ...
