Intelligent traffic signal lamp switching system and method

Abstract

The invention discloses an intelligent traffic signal lamp switching system and method. The system comprises a camera shooting system, a pressure sensing system, a signal lamp control system and traffic signal lamps, wherein the camera shooting system is used for obtaining road image data and sending the road image data to the signal lamp control system; the pressure sensing system is used for detecting road surface pressure data and sending the road surface pressure data to the signal lamp control system; the signal lamp control system is used for calculating the traffic flow grade on the road according to the received road image data and road surface pressure data, and if the calculation results are the same, a switching scheme is generated according to the calculated traffic flow gradeand sent to the traffic signal lamps; and the traffic signal lamps are used for conducting signal switching according to the switching scheme. The system and the method can effectively reduce trafficjam and fully utilize road resources by detecting traffic flow conditions such as road traffic flow and pedestrian flow in real time and controlling switching of the traffic signal lamps according tothe traffic flow conditions.

Description

technical field [0001] The invention relates to the field of traffic control, in particular to an intelligent traffic signal light switching system and method. Background technique [0002] The continuous acceleration of the urbanization process has led to a sharp increase in urban population and vehicles, and traffic congestion has become more and more serious, which has obviously seriously affected the daily life of citizens. The traditional road traffic light is a timing control system, that is, the duration of the green light and the red light is fixed. Regardless of whether there are vehicles passing by, the switching of the traffic light must be switched according to a given time, which cannot be based on the real-time situation of the road. If switching is performed, one road will be crowded with vehicles and people, while the other road will have less traffic and people, which seriously affects the traffic efficiency and wastes road resources.
