Embodiment 1

[0044] This embodiment provides a monitoring system for congestion trigger points based on radar tracking technology, such as figure 1 As shown, it includes a radar tracking unit, a congestion judgment unit, a congestion trigger point judgment unit and a display unit. in:

[0045] The radar tracking unit continuously tracks the running vehicles throughout the whole process, and obtains the position and speed of each vehicle in real time.

[0046] The congestion judging unit includes a first judging module and a second judging module. The first judging module judges whether the speeds of all the vehicles being tracked are lower than a speed threshold when the speeds of all the vehicles being tracked are consistent. In the second judging module, when the speeds of all the tracked vehicles are lower than the speed threshold, it is judged that the road is congested but not the congestion trigger point.

[0047]The congestion trigger point judging unit includes a third judging mo...

Embodiment 2

[0056] This embodiment provides a method for monitoring congestion trigger points based on radar tracking technology, as shown in Figure 3, comprising the following steps:

[0057] S1: Use radar tracking technology to continuously track vehicles on the road, and obtain the position and speed of each vehicle in real time.

[0058] S2: Judging whether the road is congested according to the speed of all tracked vehicles, which specifically includes:

[0059] S21: Determine whether the speeds of all the tracked vehicles are the same, if not, go to step S3, and if they are consistent, go to step S22.

[0060] S22: Determine whether the vehicle speeds are all lower than the speed threshold, if so, determine that the road is congested but not the cause of the congestion, record the time when the road congestion occurs, and then proceed to step S5, otherwise return to step S1.

[0061] S3: Judging whether there is a congestion trigger point on the road according to the speed change o...

Abstract

The invention discloses a jam triggering point monitoring system and method based on the radar tracking technology. Vehicles are continuously tracked through the radar tracking technology, the vehicles on an express way can be tracked, and state information of vehicles on a bridge and in a tunnel can be accurately obtained. A jam or a jam triggering point can be found on the express way or the bridge or in the tunnel in time, and therefore the jam position and the position of the jam triggering point can be directly displayed on an electronic map. According to the scheme, the moment when the jam triggering point occurs on the bridge or the tunnel or the express way and the position where the jam triggering point occurs can be correlated together to be displayed. Therefore, when a traffic manager or a decision maker replays the traffic condition in a certain area of the bridge, the tunnel and the express way, the jam triggering point can be dynamically displayed according to the occurring moment of the jam triggering point, the traffic decision maker can know the point segment of the bridge or the tunnel or the express way better, and the traffic jam happens to the point segment periodically and paroxysmally.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a monitoring system and method for congestion trigger points based on radar tracking technology. Background technique [0002] With the continuous expansion of the city scale, the traffic demand is growing rapidly, and the road traffic congestion is becoming more and more serious. In order to alleviate traffic congestion, many cities have built bridges across the sea and rivers, or built tunnels through mountains. After the completion of these bridges and tunnels, they will become urban expressways. The traffic flow is very large. Once abnormal parking cannot be quickly found and dealt with in time It will cause a large area of ​​traffic congestion in a road section or in an area, reduce the traffic capacity of bridges and tunnels, and bring great inconvenience to people's travel. To improve the traffic efficiency of bridges, tunnels and expressways, it is nec...
