Abstract

The invention provides an intersection signal lamp device. The intersection signal lamp device comprises a signal lamp system and a variable message sign device. The signal lamp system is mounted at an intersection. The variable message sign device is mounted at an upstream position in a driving direction with a certain distance to the intersection and is used for prompting a driver to change a lane before entering into an intersection channelized road. The signal lamp system adjusts driving direction indication condition of a current road and an intersection signal lamp control ratio according to road traffic environment change condition and displays the intersection signal lamp control ratio at the intersection. The signal lamp system also displays passage permission information of eachdriving direction of the current road. The signal lamp system sends the driving direction indication condition of the current road to the variable message sign device, and the variable message sign device displays the driving direction indication condition of the current road at the upstream position in the driving direction with the certain distance to the intersection.

Description

technical field [0001] The invention relates to the technical field of signal control, in particular to an intersection signal light device. Background technique [0002] As the main traffic network that carries residents' travel, the urban road network has made great contributions to improving social and economic benefits. The urban road network consists of two parts: urban roads and urban intersections. With the increase of urban road traffic demand, some roads in the urban road network show that the traffic demand is greater than the traffic supply. Therefore, signal control is widely used in urban road intersections as an effective method to regulate road traffic operation order. The signal light device is one of the important indicating devices in modern traffic signals. It is suitable for various urban road intersections, and it mainly guides vehicles and pedestrians to pass safely and orderly. [0003] At present, urban road traffic signs and markings are usually d...
