A multi-channel electronic digital taximeter that can deal with more than one passenger simultaneously

In this paper, a multi-channel taximeter that is able to deal with more than one passenger simultaneously is proposed. In order to demonstrate the theory of operation of the proposed system, a complete design for an experimental three-channel taximeter (whose prototype has been built under grant from the Egyptian Academy for Scientific and Technological Research) is presented. System location, outline, block diagrams as well as detailed circuit diagrams for the experimental taximeter are also included.
