This paper proposes a mathematical approach that can increase energy saving in timetables. The energy-efficient timetabling method, we use, maintains the planned traveling time between stations, but coordinates the train departure times at the starting station from current timetable.We formulate this problem as a multi-criteria mixed integer programming to minimize the peak energy and simultane...

The distance from the origin or destination to subway station is defined as access egress distance, which determines service coverage of station. However, little literature studies distances at level, and they may vary Therefore, this study aims explore influencing factors spatial variation level by using mobile phone positioning data more than 1.2 million anonymous users in Chengdu, China. Fir...

The coupling airflows of platform piston wind and station air-conditioning supply air is the most typical airflow organization non-screen door subway platform. By establishing a CFD software model process between in platform, velocity field coupled under different vehicle conditions numerically simulated. It has been found that: when train enters station, maximal can reach 8 m/s with near appro...

Based on the sand and pebble stratum in Beijing area, this paper studies interaction between deep-foundation-pit excavation for subway stations surrounding buildings using an orthogonal test. Moreover, it considers relative position relationship how foundation pit is set up as well different design schemes pits buildings. Results show that horizontal distance s building stiffness of itself have...

The escape of pedestrians in the subway station is hampered by floods created heavy rain. In order to explore critical flood level a so that can safely, case study Mingxiu Road Nanning, China, was conducted using numerical simulation techniques. total, 30 groups sample with different walking speeds and numbers were randomly generated Monte Carlo method, 3D software used for simulation. simulate...
