Privacy preserving in location-based service (LBS) has been an important issue in Vehicular Ad hoc Network (VANET). Traditional k-anonymity algorithm dealing with location privacy protecting problem does not consider vehicle's mobility and inner collaborator. In this paper, we propose a new algorithm which uses dynamic and mobile aware anonymous peer selecting algorithm to improve the anonymity and...
The Safe following distance is closely associated with vehicle braking process. The braking process consists of three stages. The key problem in this research area is to quantitatively describe each stage. In this paper a framework is presented to model the safe following distance by analyzing the braking process. In this framework we focus on the third braking stage, continuous braking stage, where...
Overspeed is a major factor causing road traffic accidents in China. Since the early 1980s, researchers have developed various algorithms to extract speed information from traffic image sequences. In this paper, an algorithm is proposed to evaluate the speed of the accident vehicle by videos. With human interaction, control points are refined by corner detector and then used for two-dimension geometric...
