ENLC: Embedded Based Vehicle Navigation and Lane Change Assistance System

Transportation has increasingly become an important component in the national economy and daily life. So it is necessary to build a modern intelligent vehicle navigation and lane change assistance system. The system will help to reduce the traffic congestion on roads, provide better lane changing assistance to drivers, prevent over speeding and over taking of vehicles and reduce accidents. The main objective of the proposed system ENLC (Embedded Vehicle Navigation and Lane Changing Assistance System) is to operate the vehicle in safe speed at critical zones and proper real time lane changing assistance. The data (speed of the vehicle, position, lane etc.,) capture takes place in the designed system for the purpose to monitor the driving behavior of the driver. When the vehicle is in danger of leaving the lane unintentionally the system will deliver a warning to the driver of that vehicle and also to the nearby vehicles. It is integrated with the technology of the GSM and the GPS for the accurate tracking of the vehicle. The system also sends faulty driving message and emergency warning message to the traffic monitoring authority. The micro-controller plays a crucial role in the system in terms of the implementation and the interfacing of the external modules and carrying out the lane-changing algorithm. The test bed is created on the present method where a lot of analysis takes place in the On Board Embedded System designed for Vehicle Navigation. The designed system was tested on a 4-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. We have compared the AODV and GPSR routing protocols in changing topology and high mobility with respect to our algorithm. The quality of service is studied on the basis of end-to-end delay and packet loss ratio.
