It becomes an exigent issue of the traffic control how to lead the traffic effectively, exploit the traffic resource adequately, avoid jam and reduce traffic accidents. Often, when people buy cars, they never consider the city's environmental problems, daily traffic jams, and the limited amount of parking spaces. The road designer and engineers have not designed and built the new road to solve traffic jam, but instead introduced more jam. So people begin to thrash out the way of traffic crowding and jamming, now fremdness have developed intelligent system which measure the flux of vehicle to implement traffic command.
The right solution is to lay down more gallop bridges, overpasses and underpasses in big cities. The government not only needs to build more roads, but also encourage people to take public transport. You're doing your part for the environment by using public transportation, too.
