Design and Implementation of a Low Cost Digital Bus Passenger Counter

Abstract

Accountability is an important issue when buses are to be use for transport purposes. This research is principally aimed at the design and implementation of a simple and effective digital bus passenger counter. The work is mainly the design and construction of an electronics counter, counts the number of passengers going into or out of a bus or the number of cars going into or out of a gate. The set of methods and principles used in achieving the circuit are called the top-down methodology. The actual state of the entrance which coincides with the exit was noted. Two-switch system was employed in order to avoid double counting; thus, counting is done in one direction. The switches are connected in such a way that a pulse is sent only when they are triggered in one direction, this result to the introduction of a transistor for connected to the seven-segment display. The circuit counts a maximum of 999 after which it reset to zero. The real implementation of the device is done on this work.
