Growing traffic congestion is choking most of the world s overloaded roads. Intelligent vehicles and automated highways could solve this problem. Anyone who drives to work in any metropolitan areas knows that highway traffic congestion is getting worse. Average travel speed on a crowded commuter corridors near large cities drop to about 36 miles per hour at rush hour, leading annually to some 5 billion collective hours of delay and estimated productivity loses of about 50 billion dollars nationwide. Meanwhile the cars. trucks and buses caught in chronic traffic janis waste vast amounts of fi!el as they emit copious quantities of exhaust. Although the public may be loathe to face it, the unimpeded mobility of the automobile is threatened by traffic choked roadways.
The traditional solution has been to construct more and larger roadways, but that is no longer seen as viable option by transportation planners due to high fmanÃƒÂ©ial, social and environmental costs of such giant project and implimentations. Only other method was the efficient use of the existing road network using advanced road technology. But the diverse group that comprise the countries transportation community such as federal, state and local govermnent agencies, industries, academia, trade associations and consumer and public-interest groups where always on intense debate as to what form that system should take.
It was needed to better meet the seemingly unsatisfiable demand or the freedom and mobility provided by cars and other vehicles. For this it was necessary to find ways to operate the existing system more efficiently and effectively. One approach would be to develop automated highways that features a lane or a set of lanes on which vehicles equipped with specialised sensors and wireless communication systems could travel under perhaps in small convoys or platoons. Vehicles could be temporarily linked together in communication networks, which would allow the continuous exchange of information about speed, acceleration, braking, obstacles and so forth. Small networks of computers installed in vehicles and along selected roadways could closely co-ordinate vehicles and harmonise the traffic flow maximising highway capacity and passenger safety.

AUTOMATED GUIDED VEHICLES
-AGVs increase efficiency and reduce costs by helping to automate a manufacturing facility or warehouse.
-AGVs can carry loads or tow objects behind them in trailers. The trailers can be used to move raw materials or finished product. The AGV can also store objects on a bed. some AGVs use fork lifts to lift objects for storage. AGVs are employed in nearly every industry, including, paper, metals, newspaper and general manufacturing. .
- An AGV can also be called a laser guided vehicle(LGV) or self-guided vehicle (SGV). In Germany the technology is also called Fahrerlose Transport system (FTS) and in Sweden Forarlosa trucker.
- AGVs are available in a variety of models and can be used to move products on an assembly line, transport goods throughout a plant or warehouse.
History of AGV’S
The first AGV was brought to market in the 1950s, by Barrett Electronics of Northbrook, and at the time it was simply a tow truck that followed a wire in the floor instead of a rail. over the years the technology has become more sophisticated and today automated vehicles are mainly Laser navigated ex: LGV.
In an automated process, LGVs are programmed to communicate with other robots to ensure product is moved smoothly through the warehouse, whether it is being stored for future use or sent directly to shipping areas. Today the AGV plays an important role in the design of new factories and warehouses.
