Problems solved by technology
Due to the location of the existing detectors, it is impossible to effectively identify the overflow of the intersection, so it is also impossible to optimize the intersection under the overflow state.

Embodiment Construction
[0019] The present invention will be further described below in conjunction with the drawings.
[0020] The signal control method for anti-locking at intersections of the present invention, such as figure 1 As shown, it is achieved through the following steps:
[0021] Step 1: Determine the installation position of the overflow detector in the direction of the main road at the intersection;
[0022] Such as figure 2 As shown, measure the width of the section perpendicular to the main road at intersection n And measure the section R between intersection n and the adjacent downstream intersection n+1 n, n+1 The length of L n, n+1 ; At the same time, measure the congestion density k of the section between intersection n and n+1 j ; And collect the upstream stop line and section R of intersection n n, n+1 Vehicle density at the end of the queue k s , And take the average of i times . In practice, the vehicle is in R n, n+1 The position at the end of the queue is constantly changing, ...

The invention discloses a signal control method for anti-locking at an intersection. First, after determining the installation position of the overflow detector in the direction of the main road at the intersection through measurement calculation, an overflow sensor is installed at the corresponding position; the overflow sensor is used to judge the intersection in real time. Whether the intersection n will be in an overflow state; through the overflow detector, the vehicle speed passing through the overflow detector is obtained in real time, and the average speed value is calculated, compared with the preset fixed speed threshold, to determine whether the intersection n will In the state of overflow; if there will be traffic overflow at the intersection n, at this time, optimize the preset signal timing of the traffic lights at the intersection. If the speed of the vehicle is greater than the speed threshold, no traffic overflow will occur at the intersection. At this time, the traffic lights at the intersection will operate according to the preset signal timing. The invention has the advantages of effectively preventing the occurrence of traffic overflow, avoiding the phenomenon of "running the green light", and maintaining the traffic order at the intersection.
Description
Technical field [0001] The invention relates to the field of urban road traffic control, and in particular to a traffic signal control method for anti-locking at intersections. Background technique [0002] Due to the impact of supersaturated traffic at urban intersections, the length of the line of vehicles in a certain direction will exceed the length of the road section, causing the intersection to be in an overflow state. In this case, according to traffic laws, the vehicles in the direction of the overflow must stop near the parking line and are not allowed to enter the intersection until the intersection has enough space to accommodate these vehicles. However, in many crowded cities, because drivers are not familiar with these laws and regulations, as long as the signal light is green, even if the intersection is overflowing, the vehicle continues to enter the intersection. This "green light" phenomenon occurs frequently, causing the intersection to lock up. , It affects t...
