CONTENTS

This is basically a GPS system which is designed with the intention of reducing the road mishaps.

Vehicular network can be deployed by network operators and service providers or through integration between operators, providers, and a governmental authority.

Recent advances in wireless technologies and the current and advancing trends in ad hoc network scenarios allow a number of deployment architectures for vehicular networks, in highway, rural, and city environments.

INTRODUCTION

Accidents have been taking thousands of lives each year.

The main motivation for vehicular communication systems is

safety and eliminating the excessive cost of traffic collisions. Study shows - “About 60% roadway collisions could be

avoided if the operator of the vehicle was provided warning at least one-half second prior to a collision”

Vehicular networks can help in avoiding congestion and finding better routes by processing real time data.

MOTIVATION

Vehicular communications is mainly motivated by the desire to implement Intelligent Transport Systems (ITS) because of their key benefits in safety and traveling ease.

Vehicle Infrastructure Integration (VII), seeks to increase safety by providing vehicle to vehicle and vehicle to roadside units communications through Dedicated Short Range Communications (DSRC).

Development

V2V (short for vehicle to vehicle) is an automobile technology designed to allow automobiles to "talk" to each other.

V2V is currently in active development by General Motors.

In 2001, it was mentioned in a publication [8]

that ad hoc networks can be formed by cars and such networks can help overcome blind spots, avoid accidents, etc.

Safety Traffic management Travel-related information Nearest Petrol Pump, Workshop etc.. Information about Blind Crossing, School

proximity, Railway crossing etc… Presence of obstacles on road Traffic Safety can be improved if drivers have the ability to see further down the road.

Applications

Warnings on entering intersections. Warnings on departing the highways Obstacle discovery Sudden halts warnings Reporting accidents Lane change warnings

SAFETY

Providing safety is the primary objective of vehicular communication networks.

Traffic management is utilized by authorities to ease traffic flow and provide a real time response to congestions.

Variable speed limits Adaptable traffic lights Automated traffic intersection control[10]

Accommodating ambulances, fire trucks, and police cars

Traffic management

Roadside units can provide drivers with information which help them in controlling the vehicle.

Parking a vehicle Cruise control Lane keeping assistance Roadsign recognition

Driver assistance systems

For reaching a destination there are usually many different routes. By collecting relevant information system can find the best paths in terms of travel time, expenses (such as toll and fuel).

Cars can talk to each other to inform you about traffic jams before you reach them so that you can take less congested road.

Direction and route optimization

In an unfamiliar town drivers may be assisted to find relevant information about available services:

Maps Business locations Car services

Travelled Related Information

The system will be ineffective when there is a large snowfall, high precipitation, as there is a possibility of faulty interpretation of data especially while using laser or ultrasonic sources for sensing , in these cases the system will be automatically turned off.

The system is also turns off when there is a fault in the program or hardware.

Automatic deactivation of system

Use of radar, laser, ultrasonic sensors have certain limitations and will not offer communication between large number of vehicles, such as vehicles at a junction, etc.

GPS and wifi are the two methods by which any type of communication can be achieved in all types of conditions.

Future developments

Artificial Passenger Dedicated Short Range Communications Intelligent transportation system Radio Wireless LAN

Front to rear and front to front collisions are identified on straight and curved roads.

Algorithm runs and calculates the expected trajectory of the vehicle and relative distances and velocities of surrounding vehicles.

Based on the analysed information, it sends information to driver about the safest path that can be taken.

Summary of vehicular communication systems

IVC communication is an emerging area and important source of research thanks to the improvements of in-vehicle computing and processing capabilities and also the advancements in mobile and wireless communication.

Design a protocol for IVC is extremely challenging, since it has to deal with the high mobility of vehicles, and also offer a secure communication.
