Abstract:
Traffic management is one of the most prioritized processes that both developing and developed countries can’t do away without. Proper traffic management can help to reduce time wasting, accidents, and increase workers’ productivity thereby speeding up the rate of economic development. This project was developed to reduce the average car waiting time and accidents at T-junctions. It reduces the waiting time by giving time for green light according to the traffic density. The system takes care of three conditions i.e., no traffic, little traffic and too much traffic and these conditions are determined using ultrasonic sensors. The time given to vehicles from a particular lane depends on its traffic density. If a lane has no vehicle the system switches to another lane, if a lane has little traffic the green light shows for some short time and if the active lane has too much traffic the lights show green light for a longer time before switching to the next lane.
The system also has the lane blocking module that closes the lane when the lights are showing red to avoid the risk of accidents when cars cross during the red lights time. To ensure that these people get to know when the lights are about to turn red, the 7-segmets display are used to show the time remaining to stop crossing the junction for the active lane and they display the waiting time for the lanes that are not active.
The web application is used by drivers to view traffic at these junctions so that they can be able to use the alternative road in case traffic is too much. It is also used by administrators to add other junctions to the system, control time for little traffic and high traffic and also storing data about traffic at junctions that can be used for further research or in planning.
