Urban Road Sections Travel Time Estimation Based on Real-time Traffic Information
Urban transportation dynamic guidance systems foundation is estimation accurately of the road section travel time.At present exists the method needs to carry on the model to the complex transportation system or is only is suitable under specific traffic conditions,causes the travel time estimation not exactly.Introduces SVR in the road section travel time estimation,proposed the road section travel time estimates feate vectors,had considered the traffic light to travel times influence,and the identical road section travel time according to the direct moving,left-turn,right-turn are estimated respectively,then raises the estimate rate of accuracy.The experiment results indicated that with certain sampling interval,estimate the urban road 4 kind of road section travel times,the relative error is smaller than 10%,can construct the urban transportation dynamic guidance systems necessity satisfied.
