Cooperative collision warning system for road vehicles, enabled by recent advances in positioning systems and wireless communication technologies, can potentially reduce traffic accident significantly. To improve the system, we propose a graph model to represent interactions between multiple road vehicles in a specific region and at a specific time. Given a list of vehicles in vicinity, we can generate...
Communication of vehicle information to neighbor vehicles is an important factor for safe driving systems in intelligent transport system. Additionally, big-size vehicles on the real road environments may interrupt communication between vehicles. Therefore, an adequate vehicle should forward the vehicle information in the delivery of the vehicle information to neighbor vehicles. This paper proposes...
Emergency service vehicles need safety and fluent paths to save time. In this paper, a centralized traffic control mechanism is proposed for the evacuation of vehicles that drive toward the dedicated path of the emergency vehicles (EV), e.g. ambulance, fire engines, police cars, etc, using the dedicated short range communications (DSRC) protocol. In our proposed mechanism, a centralized server is...
Vehicle License Plate of GA36-2007 has overcome most defects of GA36-1992, but there are still some disadvantages on visibility, uniqueness and intelligence. At present the automatic vehicle identification system is limited on image identification technology, which still has many shortages. In this paper, we propose a new type design of vehicle license plate and develop a matched secure automatic...
Automakers are trying to make vehicles more intelligent and safe by embedding processors which can be used to implement ldquoby-wirerdquo applications for taking smart decisions on the road or assisting the driver in doing the same. Given this proliferation, there is a need to minimize the computing power required without affecting the performance and safety of the applications. The latter is especially...
In this paper, we propose SBRM (Score-Based Routing Mechanism), a hybrid forwarding protocol based on the use of a modified contention-based forwarding coupled with carry then forward mechanism. Our solution combines different forwarding schemes and takes profit from advantages of each mechanism. Every node calculates its own Score to decide if it will be the next forwarder. The Score computation...
