Method of Handover Road Network Calibration Based on Mobile Phone Handover Location Technology

Abstract:

The paper presents a review of the principle of road travel speed data collection based on mobile phone handover location technology and the road travel speed calculation and handover road network calibration method.Handover fluctuation seriously affects handover road network calibration and the cause is explained by wireless signal propagation.The calibration method is proved by searching the path with the biggest weight in directed graph. Finally, the applicability of this method is discussed about the handover sequence stability, handover coordinate precision, mobile phone sample number. The calibration method is of great applicability in the open and low density areas.
