DASITS: Driver Assistance System in Intelligent Transport System

The growing number of vehicles on the roads worldwide, lead to increase in the number of road traffic accidents. These are recognized as a major public safety problem. In this context, connected vehicles are considered as the key enabling technology to improve road safety and the emergence of next generation cooperative intelligent transport systems (ITS). In ITS, 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 could play a crucial role in the applications of ITS, safeguarding both the drivers and the passengers and thus maintaining a safe on-road environment. In this paper we propose a Driver Assistance System in Intelligent Transport System based on the speed of vehicles, for effective lane changing in the dynamic mobility model. In our approach we present the lane changing based system on speed and minimum gap between the vehicles. The paper focuses towards the development of an Intelligent Transportation System that provides timely, reliable information to the drivers and the concerned authorities. The test bed is created on the techniques used in the proposed system where the analysis takes place in the On Board Embedded System designed for Vehicle Navigation. The designed system was tested on a Four Lane road at Neemrana in India. Successful simulations have been conducted along with real time network parameters to maximize the QoS (quality of service) and performance using SUMO and NS-2. The system implementation together with our findings is presented in this paper. To illustrate our approach we present some results of the simulation using NS-2.
