A kind of quick and precisely prediction vehicle method by road trip time

The invention discloses a kind of quick and precisely prediction vehicle method by road trip time, belong to intelligent transportation field.This method is: a, obtain all bayonet socket site information and the history information of vehicles in a period of time；B, obtain starting point bayonet socket website A vehicle buffer memory；C, judge that whether the predicting travel time of the bayonet socket Bi adjacent with bayonet socket A is complete；D, number-plate number matched and searched are with bayonet socket A for starting point, and Bi is the vehicle registration of terminal；E, calculate present period and previous period vehicle hourage from starting point bayonet socket website A to terminal bayonet socket website Bi；F, employing Kalman Algorithm predict the hourage of subsequent period vehicle；G, coefficient calculations of blocking up；H, hourage are detected Forecasting Methodology and terminate.The present invention can dope vehicle rapidly and accurately and pass through the hourage in each adjacent bayonet socket website section, it is adaptable to intelligent transportation system, traffic block port system, control of traffic and road system, Traveler Information system and Traffic Flux Information Detection system.
