Embodiment 1
[0033] The embodiment of the present invention provides a lane light control system at a merging point on an expressway, which is applied to a specific application scenario of controlling the traffic flow entering or exiting a main road at a merging point or a diverging point in an expressway, such as figure 1 shown, including:
[0034] The first stop line is arranged on the downstream of the merging road section 201 of the expressway, and the first lane light 30 is arranged in front of the first stop line; the expressway includes: the first lane 10, the second lane 20, the ramp 50 and When exiting the ramp 60 , the second lane 20 includes a diverging road section 202 and a merging road section 201 .
[0035] Exemplarily, the entering direction and the exiting direction of the expressway section are predetermined, and the motor vehicle enters from the entering direction and exits from the exiting direction, and the area passing through first is equal to the area passing throug...
Embodiment 2
[0056] An embodiment of the present invention provides a method for controlling lane lights at a confluence point of an expressway, which is applied to the system described in any of the above embodiments, such as Figure 4 As shown, the method includes:
[0057] Step S11: Obtain the driving information of each motor vehicle on the expressway, on-ramp, and off-ramp through the radar video tracking and detection device, wherein the driving information includes: position information at the current moment, speed information at the current moment, and The time information of arriving at the corresponding stop line, according to the above position information and speed information, correspondingly calculated time information of arriving at the designated position.
[0058] Step S12: According to the driving information, determine whether there is a motor vehicle on the merging road section and the on-ramp. In this embodiment, it can be judged on the merging road section on the seco...

Abstract
The invention provides an express way confluence point lane lamp control system and method, and the system comprises a first stop line which is disposed at the downstream of a converging road sectionof an express way and is provided with a first lane lamp in front of the first stop line, wherein the express way comprises a first lane, a second lane, a driving-in ramp and a driving-out ramp, the second lane comprising a shunting road section and the converging road section, the driving-in ramp intersecting with the second lane at the converging road section, and the driving-out ramp being connected with the second lane at the shunting road section; a second stop line which is arranged at the joint of the driving-in ramp and the shunting road section, wherein a second lane lamp is arrangedin front of the second stop line; a radar video tracking detection device which is arranged on the express way and the driving-in ramp and is used for acquiring driving information of the motor vehicle; and a lane lamp control device which is in communication connection with the radar video tracking detection device and is used for controlling the first lane lamp and/or the second lane lamp according to the driving information acquired by the radar video tracking detection device.
Description
technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a system and method for controlling lane lights at a confluence point of an expressway. Background technique [0002] The merging point and diverging point of the expressway are the source of periodic congestion on the expressway. How to accurately and effectively reduce the duration of the source of congestion caused by the merging point is a worldwide problem. [0003] Congestion of expressways during peak hours is common in large cities at home and abroad. It is generally believed that expressways are not controlled by signal lights and there should be no traffic jams. The expressway of the Fifth Ring Road has very serious traffic congestion. After analyzing the survey data, most of the sources of congestion occur at the merging point or the diverging point. The management concept of dynamic merging and orderly diverging proposed by the first inventor requires the dr...
