The Rational Length of the Center Loop Line of Urban Rail Transit

摘要

The urban transit becomes serious because of the city getting larger and larger. The loop line is a special kind of line in urban rail transit.Because of its special features.It must be calculated the rational length of the center loop line of urban rail transit.The function of distribute the passenger flow of the loop line is used to calculate the rational minimum length.Distributing area is used to calculate the rational maxima length in the paper.With the successive steps of derivation, the rational minimum length and the rational minimum maxima length are worked out.It has make great effect on the practical planning.
