Traffic congestion is a source of significant economic and social costs in urban areas. Intelligent Transportation Systems (ITS) are a promising means to help alleviate congestion by utilizing advanced sensing, computing, and communication technologies. This paper investigates a basic ITS framework - Advanced Traveler Information System (ATIS) - using wireless vehicle-to-vehicle and vehicle-to-roadside...
To act intelligently in dynamic environments, a system must understand the current situation it is involved in at any given time. This requires dealing with temporal context, handling multiple and ambiguous interpretations, and accounting for various sources of uncertainty. In this paper we propose a probabilistic approach to modeling and recognizing situations. We define a situation as a distribution...
With the development of the intelligent transport system, it has become an inevitable trend to achieve dynamic navigation services in adapting real-time traffic information. ESRI shapefile digital map format is firstly introduced in this paper, and a real-time navigation data model based on user-defined layers in shapefile, which makes it feasible for vehicle navigation applications, is proposed next...
