Description
Technical Field
The present disclosure relates to traffic control technology, and in particular, to a system and method for controlling pedestrian crossing coordination green waves.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
In recent years, the coordinated control of pedestrian crossing at intersections or road sections is widely applied, the pedestrian crossing efficiency and the road traffic capacity are greatly improved, and the pedestrian crossing safety is also ensured to a certain extent. According to traffic flow arrival theory, for pedestrians, there are the following cases when arriving at the street-crossing zebra crossing:
(1) the arrival is a red light. At this time, the waiting time is needed until the phase is changed, the green light is released, the specific waiting time is the remaining time of the red light phase, and the remaining time is recorded as T 1 ；
(2) The arrival is green light. At the moment, the traffic can be directly carried out without standing waiting;
(3) green flash on arrival. At the moment, the user needs to wait, does not suggest forced passing, and if forced passing is performed, potential safety hazards exist; meanwhile, even if the green light is finished, the pedestrian does not finish crossing the street, the motor vehicle driver can wait for the pedestrian to pass, and after waiting for the pedestrian to finish crossing the street, the vehicle is restarted, so that the parking delay is increased. The correct way is that the traffic light can pass until the green light of the next period is lighted. Suppose the red light display time of the crosswalk period is T 2 The residual green flash time is T when arriving 3 The waiting time in this case is T 2 +T 3 。
It can be seen that when the pedestrian reaches the zebra crossing of the street, and is in both the conditions (1) and (3), the pedestrian is not forced to cross the street, and needs to wait until the next green light is turned on. This causes the waste of pedestrian's passing time, has increased pedestrian's stroke delay, influences the passing efficiency of crossing the street.
According to domestic investigation, the domestic pedestrian waiting time generally exceeds 80s, and some of the domestic pedestrian waiting time even reaches 120s, and the time cost is immeasurable in addition to the acceleration of the contemporary life rhythm, and the pedestrian waiting time far exceeds the tolerance time of the pedestrian, so that the pedestrian is easy to generate anxiety, and the violation rate of the pedestrian is increased.
The inventors found that the following problems exist in the existing pedestrian crossing control system:
firstly, the existing coordination scheme generally carries out pedestrian crossing coordination control in a crossing or a road section crossing street region, and the existing coordination scheme is mainly used for controlling green waves of a head clearance of a motor vehicle or a motor vehicle lane and is less used for controlling pedestrian crossing street. On one hand, the green light phase time is wasted, on the other hand, the probability of traffic accidents is increased, meanwhile, the starting time of the motor vehicle after stopping the line is prolonged, the stopping delay is increased, and the traffic capacity is reduced.
Secondly, the existing coordination control scheme only considers the contradiction between people and vehicles at the coordination zebra crossing, and the passing efficiency of pedestrians on road sections is not obviously improved. In the process of changing the red light into the green light, a countdown reminding is not generally available, so that pedestrians who are driving to an intersection cannot judge the control condition of the street crossing signal when arriving. The pedestrian time conflict is obvious, the pedestrian psychology is influenced, and the tolerance of the road environment can be changed. The existing sidewalk has obvious opposite conflict, is easy to generate the condition of unclear road rights, causes a certain delay when the opposite people flow are intersected, and has more obvious conflict in the process of urgent travel of the pedestrians.
