Modeling of Traffic Light Control Using LABview

As the problem of urban traffic congestion spreads & occurrence of road accidents increase, there is a pressing need for the introduction of advanced technology and equipment to improve the traffic control algorithms to better accommodate this increasing demand. The simplest way for controlling a traffic light is using timer for each phase. Another way is to use electronic sensors in order to detect vehicles, and produce signal that cycles. In this paper we propose the LABVIEW simulation model for controlling the traffic lights based on time interval. This simulation model can extended to control the time interval of the traffic light based on traffic density system for controlling the traffic light by any other suitable method.
