In this study an Overtake Mishap preventive road safety system is designed. The System makes driver aware about the platoon of which its vehicle is a part. The system helps driver to know the overtaking behavior of back vehicle. The system with the help of front vehicle's response also guides driver when it decides to overtake it. The Road-Side-Devices help to maintain the communication amongst vehicles...
In this paper, a novel approach for improving vehicular positioning is presented. This method is based on the cooperation of the vehicles by communicating their measured information about their position. This method consists of two steps. In the first step, we introduce our cooperative map matching method. This map matching method uses the V2V communication in a vehicular ad hoc network (VANET) to...
In vehicular ad hoc networks (VANETs) the network services and applications (e.g., safety messages) will require an exchange of vehicle and event location information. Effective lane changing and routing in Vehicular Ad hoc Networks is a challenging task. This paper aims to propose a solution to ensure the safety of drivers while changing lanes on the highways. Efficient and faster routing protocols...
New communication technologies integrated into modern vehicles offer a better assistance to people injured in traffic accidents. Recent studies show how hybrid communication capabilities should be supported and improve overall rescue process. There are a variety of areas, where in a need exists for a system capable of identifying and characterize the severity of the accidents using KDD process. In...
The invention relates to the sphere of traffic congestion detection, and relates to a traffic congestion detecting system and technique. Vehicles will directly communicate with each other and with infrastructure; a wholly new paradigm for vehicle safety applications will be created. New challenges are created by high vehicle speeds and extremely dynamic operational environments. New necessities, necessitated...
This paper proposes a design and implementation of the On-Board Unit (OBU) in the Vehicular Ad Hoc Network (VANET) for highways, and realizes vehicle-to-vehicle (V2V) communication. The system is divided into four parts including central control module, wireless communication module, GPS module, and human-machine interface module. The hardware platform is consisting of an ARM11-based embedded development...
In this paper a novel Vehicular cooperative map matching method is presented. This map matching method uses the V2V communication in a VANET to exchange GPS information between vehicles. Then vehicles can apply the road constraints of other vehicles in their own map matching process and acquire a significant improvement in their positioning. The dependency of GPS measurements between different vehicles,...
A vehicle-mounted GPS receiver used for localization can suffer from signal blockage. To remedy to this problem, GPS/ INS integration can be considered as a solution in some cases. However, in the case of urban areas where there are severe multipath conditions, the performance degrades considerably. The last decade have seen many proposals of techniques aiming at improving the accuracy of GPS positions...
Vehicle position is one of the most valuable pieces of information in a Vehicular Ad-hoc Network (VANET). The main contribution of this work is a novel approach to enhancing position security in VANETs. We propose a general active detection architecture including two components: eye-devices and ear-devices. Eye-devices include radar, infrared, camera, etc. Ear-device is the wireless transceiver. We...
VANET (Vehicular Ad-hoc Network) that is used for vehicular-to-vehicular and vehicular-to-roadside communication is well known as one of the representative application of ad hoc networks. One of the representative mechanisms is Epidemic Routing that adopts the concept of Store-Carry-Forward. However, in Store-Carry-Forward mechanism, each node stores data packets in the buffer, and whenever the node...
A novel vehicular driving navigation system based on VANET is presented. The hardware of the system is an ARM9 embedded device with GPS, 802.11 communication module and human machine interface (HMI). The HMI displays the driving states of the adjacent vehicles and the emergency road information to remind the driver of safety driving. A power control mechanism is also applied in this system to increase...
Safety is one of main goals of VANET (Vehicular ad hoc Network). In Vehicle Interactive Navigation System, according to vehicle-to-vehicle (V2V) communications vehicle can share its own location within the lane and other information (speed, velocity, acceleration) to the neighboring vehicles so that it allows vehicles to coordinate maneuvers for safety goal such as collision avoidance. Traditionally,...
VANET has become an interesting research field because we can get a lot of benefit from VANET such as to enhance road safety, reduce traffic congestion and etc. However VANET has some drawbacks such as broadcast storm disrupting network communication, rapid topology changes. These problems need solutions to improve VANET's performance. In this paper we propose a new approach to reduce broadcast storm...
