Safe and efficient passage guiding device for traffic flow at plane intersection

Abstract

The embodiment of the present application discloses a signal light control method at a level intersection, the level intersection includes an entrance lane Ci and an entrance lane Cj, and the entrance lane Ci and the entrance lane Cj both have a guide area. The guide area of ​​the entrance lane Ci is provided with a guide light array, the guide light array includes NCi horizontal ground signal light groups, and each horizontal ground signal light group in the NCi horizontal ground signal light groups includes at least one ground semaphore. The NCi horizontal ground signal light groups include a horizontal ground signal light group Ci-p and a horizontal ground signal light group Ci-q, and the horizontal ground signal light group Ci-p is arranged at the exit boundary line position of the guide area, and the horizontal ground signal light group Ci -q is set at the entry boundary line position of the guidance area.

Description

technical field [0001] This application relates to the technical field of transportation electronics, and in particular mainly relates to a signal light control method and related devices and related systems at level intersections. Background technique [0002] At present, with the acceleration of urbanization and the improvement of people's living standards, the number of motor vehicles in many large cities is increasing year by year, which in turn causes more and more serious traffic congestion problems. Urban traffic congestion has had a certain impact on people's daily travel, and has restricted economic development to a large extent. Moreover, congestion increases the fuel consumption of vehicles (the fuel consumption of vehicles at idle / slow speed is usually increased by more than 50% compared with normal speed), resources and time are wasted, and vehicle exhaust emissions are also greatly increased, which seriously affects air quality. . Therefore, how to "control c...

Problems solved by technology

However, the current research progress in this industry is very slow and has little effect.

[0003] The industry generally believes that "smart roads" are an important research direction to alleviate congestion and improve road traffic efficiency. However, smart roads are still in the conceptual stage, and smart road-related products (software / hardware products) and solutions are still slowly hatching. Some giant companies in the field of transportation have begun to invest heavily in research and development in this area, but no related molding products and solutions have been launched yet.
