Wireless information on road traffic congestion at intersection

Road traffic congestion had been a major problem in the worldwide especially to the road users. This problem usually occurred at the intersection, roundabout or straight road. Intersection is an area that assigned by two or more crossing roads. Dissent movement that occurred at intersection area always causing travel delay and engender accident between vehicles. The Wireless Information on Road Traffic Congestion at Intersection is developed to provide road traffic congestion information at intersection that enable road users to avoid from entering the congestion area. Currently, television and radio broadcast only provide information on road traffic congestion for certain period of time and it shows that the present system is impractical because road users unable to get information on road traffic condition for totally 24 hours of time. Therefore, this newly system had been developed that has the ability to provide information on road traffic condition especially during congestion period. The main components that had been used in this project including PIC16F84A microcontroller, Just Another Language (JAL) PIC compiler, IC-Prog PIC programmer, wireless transmitter and receiver, Parallel Port interfacing and Graphical User Interface developed using Microsoft® Visual Basic 6.0 software. This system is suitable to be applied at the traffic light junction or road intersection.
