Adaptive conversion control system for traffic light

Abstract

The invention is applicable to the technical field of transportation planning, and provides an adaptive conversion control system for a traffic light. The system comprises a vehicle quantity calculation module, a DPS chip, a clock unit, a communication unit, a detection unit, an execution unit, and an indication lamp. The vehicle quantity calculation module is connected to the DPS chip, and is used for detecting the number of vehicles in a measurement range on the roads in the east, south, west, and north directions of a traffic light intersection and simply summarizing the data in the same direction. The clock unit is used for time reminding. The processing unit divides the traffic light into a peak state and a normal state, and performs corresponding control operations according to different traffic flows in a peak period and a normal period. The processing unit adopts the peak state during the peak period, that is, the traffic light alternately change from 60s to 120s, and adopts the normal state in the normal period, that is, the principle of majority rule. Therefore, the traffic flows in a transverse direction and a longitudinal direction can be evacuated as soon as possible;the situation that the number of the waiting vehicles at the intersection is excessive can be avoided; and traffic jams on main roads can be avoided.

Description

technical field [0001] The invention belongs to the technical field of transportation planning, in particular to an adaptive conversion control system for traffic lights. Background technique [0002] As early as the 1960s, the United States began to conduct pioneering research on intelligent transportation systems, that is, research on electronic path guidance systems. In the mid-1980s, the PATHFINDER system researched by the California Department of Transportation was successful, which accelerated the development of intelligent transportation systems. In 1990, the United States The Ministry of Transportation established an intelligent vehicle road system organization: in 1991, the American Council passed the Comprehensive Ground Transportation Efficiency Act to develop an economically effective and environmentally friendly national comprehensive ground transportation system to improve the transportation efficiency of passengers and freight. The transportation system is a c...

Problems solved by technology

[0004] The present invention provides an adaptive conversion control system for traffic lights, aiming to solve the situation that the traffic lights at each road crossing are alternately changed every few seconds. Intersecting intersections, this method will lead to a large number of vehicles blocking the main road, but there are not many vehicles passing through the traffic lights on the other side, which leads to the problem of wasting time
