The relationship between energy consumption and train delay in railway traffic
《Chinese Physics B》2010年第10期194-198,共5页李克平 范红强 
Project supported by the National Natural Science Foundation of China (Grant Nos. 60634010 and 60776829);the Changjiang Scholars and Innovative Research Team in University (Grant No. IRT0605);the State Key Laboratory of Rail Traffic Control and Safety of Beijing Jiaotong University (Grant No. RCS2008ZZ001)
Based on deterministic NaSch model, we propose a new cellular automation model for simulating train movement. In the proposed model, the reaction time of driver/train equipment is considered. Our study is focused on t...
