A Fusion Model for Floating Vehicle And Loop Detector Data Based on BP Network
Lin Si · 2009
The advantages and disadvantages of both floating vehicle and loop techniques are different.In order to get higher quality data,it needs to fuse GPS floating vehicle data with loop detector data. Focusing on this issue,the paper established a fusion model based on BP network. The model consists of three parts,the initial data generated module,data fusion module based on BP network and result analysis module. The input data are travel time,traffic volume provided by the loop detectors and travel time,number of floating vehicle provided by GPS floating vehicle.The output is travel time after fusing. The simulation result shows that the accuracy and stability of the travel time after fusing are high,and the model is effective.
