Multiple flux difference effect in the lattice hydrodynamic model
《Chinese Physics B》2012年第2期210-217,共8页Wang Tao Gao Zi-You Zhao Xiao-Mei 
supported by the National Natural Science Foundation of China (Grant Nos.70631001 and 71071012);the Fundamental Research Funds for the Central Universities (Grant Nos.2009JBM045 and 2011YJS235)
Considering the effect of multiple flux difference, an extended lattice model is proposed to improve the stability of traffic flow. The stability condition of the new model is obtained by using linear stability theory...

Efficiency promotion for an on-ramp system based on intelligent transportation system information
《Chinese Physics B》2010年第8期247-256,共10页谢东繁 高自友 赵小梅 
Project partially supported by the National Basic Research Program of China(Grant No.2006CB705500);the National Natural Science Foundation of China(Grant Nos.70631001 and 70701004);the Innovation Foundation of Science and Technology for Excellent Doctorial Candidate of Beijing Jiaotong University(Grant No.141046522)
Effect of cars with intelligent transportation systems （ITSs） on traffic flow near an on-ramp is investigated by car-following simulations. By numerical simulations, the dependences of flux on the inflow rate are in...

Traffic dynamics of an on-ramp system with a cellular automaton model
《Chinese Physics B》2010年第6期77-82,共6页李新刚 高自友 贾斌 姜锐 
Project supported by the State Key Development Program for Basic Research of China (Grant No.2006CB705500);the National Natural Science Foundation of China (Grant Nos.70631001,70501004 and 70701004);Program for New Century Excellent Talents in University (Grant No.NCET-07-0057);the Innovation Foundation of Science and Technology for Excellent Doctorial Candidate of Beijing Jiaotong University (Grant No.48025)
This paper uses the cellular automaton model to study the dynamics of traffic flow around an on-ramp with an acceleration lane. It adopts a parameter, which can reflect different lane-changing behaviour, to represent ...

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...

Cascading failures in congested complex networks with feedback被引量：2
《Chinese Physics B》2009年第11期4754-4759,共6页郑建风 高自友 傅白白 李峰 
Project partly supported by National Basic Research Program of China (Grant No 2006CB705500);National Natural Science Foundation of China (Grant Nos 70631001, 70671008 and 70801005);the Innovation Foundation of Science and Technology for Excellent Doctorial Candidate of Beijing Jiaotong University (Grant No 48033)
In this article, we investigate cascading failures in complex networks by introducing a feedback. To characterize the effect of the feedback, we define a procedure that involves a self-organization of trip distributio...
