 The growth demand and safety awareness of transportation are getting more and more important. Nowadays, the society can't function without transportation, whether by rail, port, air, ground, or sea. The transportation is a combination of infrastructure, vehicles and operations. Infrastructure is made of transport networks by roads, railways, airways, waterways and canals; vehicles generally running on the networks like automobiles, rail rapid transit, aircrafts and heavy vehicles. The operations deal with the way the vehicles operated on the networks and the procedures. Along with technical progress, people start to use Advanced Management Technology Systems to monitor and manage the ongoing traffic congestion in a better way. The purpose is to allow traffic engineers and emergency personnel to monitor traffic flow and predict trouble spots before the event occurs. The Rail Rapid Transit, a quite common city
transport network, provides frequent and convenient passenger services to transport large numbers of people in metropolitan
areas. Thus, assuring the system stability and passenger safety makes the most critical mission in rail transit system. |
