Description

technical field [0001] The invention belongs to the field of intelligent transportation, and in particular relates to a vehicle speed guidance method aiming at priority induction control intersections of main roads. Background technique [0002] In the existing traffic signal control system, because the vehicle and the traffic signal machine cannot carry out information interaction, it is difficult for the driver to predict the signal state of the downstream intersection, which results in the following two situations: ①Driving at the current speed to reach the green light at the downstream intersection Did not start, encountering a red light; ②Driving at the current speed to reach the downstream intersection, the green light has ended, encountering a red light. Both of these situations will cause unnecessary parking of vehicles, resulting in more fuel consumption, exhaust emissions, and reduced crossing efficiency. [0003] In response to the above problems, researchers at ...

[0002] In the existing traffic signal control system, because the vehicle and the traffic signal machine cannot carry out information interaction, it is difficult for the driver to predict the signal state of the downstream intersection, which results in the following two situations: ①Driving at the current speed to reach the green light at the downstream intersection Did not start, encountering a red light; ②Driving at the current speed to reach the downstream intersection, the green light has ended, encountering a red light

Both of these situations will cause unnecessary parking of vehicles, resulting in more fuel consumption, exhaust emissions, and reduced crossing efficiency

[0003] In response to the above problems, researchers at home and abroad have proposed some intersection speed guidance methods, which have achieved certain results, but there are still some shortcomings: on the one hand, due to the relatively stable signal control methods of timing control and induction control, there are still a large number of urban traffic control methods in my country. The intersection adopts these two kinds of signal control methods, but the existing vehicle speed guidance method is all aimed at the intersection controlled by the timing signal, and the vehicle speed guidance method for the induction control intersection that also exists in a large number in China has not been studied yet; The speed limit on the road section is different from the speed limit on entering the intersection. The existing research does not take into account the safety of motor vehicles passing through the intersection, which may cause traffic safety accidents caused by vehicles passing through the intersection at too high a speed.
