Using the newly emerged technology of electronic toll collection (ETC) to combine information technology and superhighways not only gives a highway the quality of intelligence, making it no longer an ordinary highway, but also can open it to endless possibilities of development. With ETC to replace manual toll collection, vehicles no longer have to slow down to go through toll stations. This can save on petroleum consumption and wear and tear of parts from applying the brakes. The radio frequency identification (RFID) technology used by ETC can get hold of vehicle information on the superhighways in real time. Through system integration, it could even combine flows of people, money and goods to form a huge database system. Furthermore it can even enhance road user safety and comfort. In the future people can query traffic projections in the next few hours simply through a cell phone and get information on traffic congestion. On the other hand toll rates can be adjusted based on peak and off-peak hours to achieve the aim of quantity control with price. 

 

The current mode of toll collection based on trips has some unfairness lying beneath. City-bound vehicles do not need to pay, but long distance north- and sound-bound vehicles need to pay a toll. As there are more vehicles in the former than in the latter, long distance road users also pay for short distance road users. Therefore it is fairer to collect tolls based on distance. A sustained superhighway has to consist of the three aspects of economy (high efficiency), environmental protection (energy saving and carbon reduction), and society (justice) for it to achieve the traffic prospect of green intelligence.
