System for search of optimal transport routes

A problem is analyzed of further development of geographic informational systems with traffic monitoring channel (GIS-TMC) in order to present to the road users effective information about the fastest (the shortest in respect of time) routes and thus to improve use of existing city transport infrastructure. To solve this task it is suggested to create dynamic (automatically updated in real time) street passing durations base, for support of which a city transport monitoring system operating in real time is necessary consisting of a network of sensors, a data collection communications system and a data processing system. It is shown that to predict a street passing duration it is enough to measure speed of transport in the characteristic points of the street. Measurements of traffic density do not significantly improve accuracy of forecast of a street passing time. Analytical formulas are presented meant to forecast a street passing time.
