Information interaction system plays an important role in establishing a real-time and high-efficient traffic management platform in Intelligent Transportation System (ITS) applications. However, the present transmission technology still exists some defects in satisfying with the real-time performance of users data demand in Vehicle-to-Vehicle (V2V) communication. In order to solve this problem, this...
In this paper, a network-based algorithm is proposed for group activity recognition with multiple people/objects and crowded scenes. This algorithm models the entire scene as an error-free network. With this network, we model objects in the scene as packages while activities as package transmission in the network. By analyzing these “package transmission” processes, activities can be detected. Based...
Vehicle-to-infrastructure (V2I) communications enable various applications for transportation, help improve road safety, transportation efficiency and comfort of travel. As vehicles change their point of attachment frequently, seamless handover becomes one of the most challenging research issues for supporting these applications. In this paper, we propose a fast handover for Proxy Mobile IPv6 (PMIPv6)...
Location tracking for vehicle plays a key role in increasing road safety and transportation efficiency. In this paper, a Wi-Fi based real-time tracking system which can work in both indoor and outdoor environments is presented. The proposed system estimates the location of vehicle using the Received Signal Strength (RSS) fingerprints of transmitted Wi-Fi Access Points (APs) and Particle Filter (PF)...
Providing an anytime, ubiquitous and reliable vehicular positioning system plays a key role in increasing road safety and transportation efficiency. Although the Global Positioning System (GPS) has been widely used in vehicle navigation, urban vehicle positioning is still a challenge because of the unavailability of GPS in dense metropolitan areas. To solve this problem, an advanced integration of...
This paper presents a method to integrate Wi-Fi networks with global positioning system (GPS) and dead reckoning (DR) system for tracking a vehicle in the urban areas by using the federated form of unscented Kalman filer (UKF) and Kalman filer (KF). Due to non-line-of-sight conditions and multipath propagation environments, the estimation of the GPS/DR integrated positioning system lacks acceptable...
In this paper, an agent-based power management for fuel cell hybrid vehicles is introduced. The focus is to improve the fuel economy of the vehicle by appropriate power assignment to the power source and braking energy recycle. The agents play a supervisor role of each plant and optimize power output of the plant by corresponding control strategy. Multi-agents work together in a cooperation way to...
