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 results to the introduction of a transistor for its switching ability. The output of the transistor is connected to the display driver, which in turn is connected to the seven segment display. The circuit counts a maximum of 999 after which it resets to zero. The real implementation of the devise is done on this work.
