Intelligent Vehicle Highway Systems

Mobility is very important in our society. People live in one city and work in another. They go to visit friends and family living in different parts of the country. Even leisure time is not always spent in their residence. Despite the Indian government’s efforts to increase the use of public transportation, the car is still a widely used means of transportation. Every time someone travels from one location to another (by car), he or she first determines the best route to reach the destination. Depending on the time of day and the day of the week, this route may be different. For example, the driver may know that a certain road is always congested at a particular time and day. As a consequence, he chooses to use a different route to avoid this congestion.

Car navigation systems (or Intelligent Vehicle Highway Systems) are being offered as a special feature of new cars of an increasing number of car-brands. These car navigation systems are capable of taking over some of the tasks that are performed by the driver such as reading the map and determining the best route to the destination. They should also take daily congestion patterns into account. Because a car navigation system uses a built-in computer to determine a route, it can compare many different routes and the user expects the system to determine the best possible or optimum route fast. This report is concerned with presenting the role of GIS- GPS integration in intelligent vehicle highway systems besides giving an in depth role of route planning algorithms that enable a car navigation system to plan optimum routes on very large real-world road networks in very little time, taking daily congestion patterns into account.
