FIELD: systems for controlling traffics of ground transport vehicles, namely automobile transport, possibly controlling automobile-taxi movement for selecting optimal motion route. ^ SUBSTANCE: system includes client terminal mounted in automobiles and on-board equipment of satellite navigation and also terminal of common supervisory system communicated through radio channel with client terminals. Each client terminal is mounted with possibility of receiving in continuous mode readings of on-board equipment of satellite navigation, with possibility of constant calculation of mean speed of automobile for fixed time period and comparison of mean speed with predetermined minimally admissible value. When mean speed becomes less than said minimally admissible value by predetermined times, geographical coordinates of place where speed begun to lower are transmitted to terminal unit of common supervisory system. If mean speed increases more than minimally admissible one, geographical coordinates of place where speed begun to increase are transmitted to terminal unit of common supervisory system. Said terminal unit is made with possibility of indicating on city map place where speed begins to lower as boundary of jam starting and place where speed begins to increase as boundary of jam termination. Such system provides monitoring of traffics along the whole area of populated zone and on inter-city highways. ^ EFFECT: increased time period of running between repairing works due to lowered load of motor, clutch and braking system, economy of fuel and improved quality of service. ^ 2 cl |
