Abstract

This paper introduces a new vehicle localization approach for global positioning system-challenged road segments (e.g., tunnels), which takes advantage of roadside units (RSUs) and in-vehicle inertial navigation system (INS). In the proposed approach, namely RSU/INS-aided localization system (RIALS), vehicles only need one RSU in their transmission range for an accurate positioning. The beacons received from the RSU along with the information provided by the INS system are used for establishing and maintaining particular locus circles. After linearization, the system of locus circle equations is solved using the linear least square estimation technique, and variations, the estimated vehicle's position is obtained. In the presence of speed and ranging, existing and INS estimation errors, the proposed RIALS adaptively sets the sufficient number of required locus circles, aiming at keeping the localization error below a given threshold. We study the effects of ranging and analytical, INS estimation errors on localization accuracy of RIALS from and simulation perspectives. Results of extensive simulations show that the localization error is more sensitive to the ranging error than the INS error. Moreover, the network traffic overhead of the proposed method is considerably lower than other competitive localization approaches. Copyright © 2015 John Wiley & Sons, Ltd.
