In recent years, the level of intelligent transportation in my country is continuously improving, and the pace of Internet and transportation integration is also accelerating. Intelligent transportation has become an important field that needs to be broken through in the construction of smart cities in my country. In T-shaped intersections, there are generally 6 red and yellow Green traffic lights, in the case of driving in both directions, there will be at least 3 intersections in the traffic flow, and in the process of driving, because it is easy to cause visual blind spots, which will affect the driver's judgment and operation errors, it is very easy to cross the T-shaped intersection. accidents such as car accidents at the intersection.

Compared with crossroads, the driving and pedestrian routes of T-shaped intersections are relatively simple. Some such T-shaped intersections only have one-way crossing sidewalks or include non-motorized vehicle lanes, that is, crossing the road sidewalks corresponding to the T-shaped vertical arm. For this kind of T-shaped intersections The current red, yellow and green traffic lights at intersections mostly adopt the method of timing signals, that is, the signal time to determine the driving time in each direction, but for some obviously there will be more pedestrians and non-motorized vehicles in some specific time periods or there will be traffic flow in some specific time periods The method of timing signals at such regional intersections is actually a waste of a lot of passing time for passable routes. This also indirectly causes some vehicles and pedestrians to grab the time of yellow lights and run red lights, which also improves The incidence of traffic accidents.
