Description
Technical Field
The invention relates to the technical field of urban rail transit, in particular to a flexible grouping rail transit train system operated at low cost and equal intervals.
Background
One of the characteristics of urban rail transit is that tidal passenger flow, i.e. passenger flow is particularly large in the early and late peak and suddenly drops in the low valley. In order to meet the operation purpose, passengers are quickly transported to a destination, more vehicles are needed to be put into, meanwhile, the time interval for vehicle operation is shortened, and the train with large capacity and high density can meet the car use requirement of the morning and evening peaks, but the train is obviously wasted in the period of the valley period, so that the problems of serious vehicle abrasion, high power consumption, more personnel input and the like are caused.
In order to solve the contradiction, in the prior art of the rail transit at present, an operation management mode of shortening an operation interval in a peak period and elongating the operation interval in a valley period is mostly adopted to adapt to the change of passenger flow, so that the operation cost is reduced. However, this operation mode can make the waiting time of passengers in the valley period too long, reduce the riding experience, and cannot avoid the abrasion condition of redundant vehicles. In the prior art, the other solution is to set a shift of the express bus, so that the express bus can only run among a plurality of core stations with larger passenger flow, and other stations can pass through. However, the fast car needs to be provided with an override line, the feasibility of certain existing rail transit lines is not high, a lot of extra input cost is increased, meanwhile, the passenger flow of each station needs to be accurately estimated by the shift setting of the fast car, the situation of sudden passenger flow cannot be dealt with, and the fast car shift is stable and regular, so that passengers need to accurately identify the fast car and the common car when riding, and the riding experience of the passengers is reduced.
