Item The design of a vehicle detector and counter system using inductive loop technology(2021) Oluwatobi AN; Tayo AO; Oladele AT; Adesina GRScheduling vehicles at multiple intersections remain an issue of concern in road traffic control. Traffic lights have been widely employed in many countries, however, determining the best intersection to grant access to using the number of vehicles present as a yardstick needs to be improved on. Therefore, this article presents the design of a vehicle detector and counter system using inductive loop technology. The proposed system is majorly made up of the inductive loop section, the electronic vehicle detector section and the counter section. The inductive loop uses an electromagnetic communication to create an electric current in a nearby wire, when a vehicle crosses the loop, the inductance of the loop is increased. Based on the oscillating signal received from the inductor loop, the electronic detector section uses a voltage comparator stage and Darlington transistor arrangement to detect the vehicles on the queue. Afterwards, two up-counters and an up/down counter were used to keep track of vehicles entering and leaving the queue. The design was simulated and tested in Proteus virtual system modelling software. The simulation results obtained revealed that the design could be employed for detecting and counting vehicles at intersections so as to effectively control traffic.
