Intelligent Transport System Today, there are many ways to travel around a large metropolitan area, for work or pleasure. You could walk, although the range is admittedly low. You could bicycle, but you still do a lot of work, and it's dangerous. You could drive a car, which takes concentration and sobriety and a license. You could ride a bus, and let someone else drive. You could take a train, and let a computer drive you. Or you could fly, and wait a long time for the plane to take off and land. All modes of transportation have advantages, and disadvantages. However, in recent decades, the single system that has won over all others is the private automobile. This allows you to go from your starting point to your destination point, with your complete control, at a reasonable speed in a reasonable time. Unfortunately, apart from the pollutants created by the vehicle itself, the fact that so many other people seem to enjoy its perceived freedom causes major traffic jams, and the requirement for traffic control devices. Too many people using too little road space at the same time causes traffic jams. It is most profound on large grade separated roads, that have limited access. There have been various solutions tried out, including high occupancy vehicle lanes, ramp metering, or road widening. Unfortunately, they simply don't solve the problem of lack of capacity. Traffic control devices impose certain controls on the flow of traffic. Most common are traffic lights. These meter the flow of traffic between two or more roads so that at no time is any vehicle in conflict with any other. However, they also impose that traffic comes to a complete stop, requiring vehicles to stop and then start again. This not only slows vehicles down, but also is the prime cause of wasted energy in urban settings. Unfortunately, cities are very reluctant to spend money. Therefore any future transport system has to be cheap for cities. This implies that current infrastructure is kept as much as possible, or improved. Using roads, the prime infrastructure available today would mean the form. factor for vehicles would stay the same, but each individual vehicle could be made more intelligent. So for tomorrow, we need to design a transport system that uses roads or a very slight improvement on roads to provide a high capacity system that provides service for everyone. This could be achieved by implementing the following eight systems, each of which provides more of a burden on the car manufacturer, but would eventually provide a system, which is automatic, safe and efficient. Firstly, all cars should have intelligence brakes and cruise control. These would remove the driver from the responsibility of having to follow along behind somebody. By pressing a button, the driver would give control of the distance between his car and the car in front. If the car in front slowed down, you would not have to wait for the brake lights to light up, the driver to see them, Wen press the brake pedal the right amount, and continuously monitor the distance. Instead the car would be programmed to continuously monitor the distance to the car in front and instantly alter its speed to match and maintain the distance. By speeding up the feedback circuit, you can close the distance of cars, and therefore increase the capacity. You also remove driver error so reducing the number of accidents. Also, cars could communicate locally with each other and ware ahead of time that following cars need to slow down. Next, you need to remove the driver from the responsibility of steering the vehicle. Having complex vision systems on a car seems over the top as they not only dramatically increase the cost of the car, but also the complexity of the control software. Instead you could build detector into the front of the car that detect the middle of a lane of t A．Y B．N C．NG
