考虑交通出行惯例的双向行人流模型研究被引量：3
《物理学报》2011年第10期42-49,共8页杨凌霄 赵小梅 高自友 郑建风 
国家自然科学基金(批准号:70701004;71071012)资助的课题~~
推广了Baek等人最近提出的一个双向行人流模型,提出了两种改进策略,并从行人平均速度-密度关系、行人空间分布密度和位置分布等方面进行了数值分析.研究发现,引入的两个新策略不仅可以提高行人流的平均速度,而且可以提高道路系统(尤其...

Combined bottleneck effect of on-ramp and bus stop in a cellular automaton model
《Chinese Physics B》2009年第12期5242-5248,共7页宋玉鲲 赵小梅 
Project supported by the National Basic Research Program of China (Grant No 2006CB705500);the National Natural Science Foundation of China (Grant Nos 70631001,70701004 and 70501004)
The combined bottleneck effect is investigated by modeling traffic systems with an on-ramp and a nearby bus stop in a two-lane cellular automaton model. Two cases, i.e. the bus stop locates in the downstream section o...
