Traffic Jam
There is no doubt that traffic congestion becomes a growing worry for the residents of most urban areas. Some major roads are regularly choked with traffic in rush hours. The limited transport capacity contributes largely to the vexing problem. How to solve the headache?.
The existing solutions to traffic jam mainly aim at creating metro bus systems and broadening major roads. Widening the existing roads can solve traffic snarls on some level. Soaring car ownership compounds the chronic annoying problem, so we must sharply reduce the heavy reliance on cars and drive a shift to the mass transportation. It is a cheap and good way. We can create a system of customized bus routes and highlight the development of subways, trolleys and light rail. The effective combination of these solutions will enable the urban areas to possess a smooth traffic.
