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
