ABSTRACT:
A technique for showing running time by sections for a tollway includes: a unit toll collector installed at a unit toll gate of a tollway for calculating a running time of vehicles leaving the unit toll gate for each entrance toll gate; indicators installed at main points of the tollway for indicating running time by sections; and a traffic control center connected to the unit toll collector and a predetermined communication network for receiving the running time of vehicles for each entrance toll gate, averaging it to obtain the overall running time by sections, and outputting it to the indicators.
