Express/local train plan optimization for urban rail transit in condition of full-length and short-turn modes

Operating the express/local train plan can meet the characteristics of imbalance of passenger volume temporal and spatial distribution, and satisfy the demands of long-distance commuters who want to travel fast. Although the program can improve the organizational operating efficiency and passenger service level, it will reduce the carrying capacity of system to some extent. Above all, based on analysing the factors of the express/local train plan and the composition of passenger travel time in detail, the 0-1 integer programming model of stopschedule plan problem was established by minimizing the passenger travel time. And combined with a simulation case, the immune genetic algorithm was designed to study the effect of line capacity.
