Abstract

The invention discloses a traffic control method and device for expressway ramps. The method includes the following steps: acquiring first detection data of a vehicle detector in the overlap area of the exit ramp of an expressway and the ground road and second detection data of a vehicle detector on the exit ramp of the expressway; determining the vehicle queuing state of the exit ramp of the expressway according to the first detection data and the second detection data; and adjusting the green time of at least one signal lamp in N signal lamps including a first signal lamp and signal lamps adjacent to the first signal lamp according to the vehicle queuing state of the exit ramp of the expressway, wherein the first signal lamp is a signal lamp in the first fork encountered by a vehicle driving into the ground road from the exit ramp of the expressway. The method and the device of the invention are used to solve the problem of traffic congestion at the junction of the exit ramp and theground road.

Description

technical field [0001] The invention relates to the technical field of expressway traffic control, in particular to a traffic control method and device for an expressway ramp. Background technique [0002] Expressway is the main skeleton of the urban road network, which has the characteristics of fast, comfortable, and large capacity, and bears a large number of motor vehicle trips. However, with the continuous growth of the number of motor vehicles and the continuous increase of traffic demand, the problem of rapid congestion has become increasingly prominent, and expressway congestion during peak hours has become the norm. The ramp is the channel connecting the expressway and the surface road, and it is often the point where the expressway congestion occurs. The ramp congestion will even spread to the regional traffic paralysis. Therefore, it is very necessary to carry out ramp control of expressways. [0003] On-ramp control is the main means of expressway control at pr...
