A study on the effects of the transit parking time on traffic flow based on cellular automata theory 下载免费PDF全文
This paper mainly deals with the effects of transit stops on vehicle speeds and conversion lane numbers in a mixed traffic lane.Based on thorough research of traffic flow and cellular automata theory,it calibrates the cellular length and the running speed.Also,a cellular automata model for mixed traffic flow on a two-lane system under a periodic boundary condition is presented herewith,which also takes into consideration the harbour-shaped transit stop as well.By means of computer simulation,the article also studies the effects of bus parking time on the traffic volume,the transit speed and the fast lane speed at the same time.The results demonstrate that,with the increase of the bus parking time,the traffic volume of the transit stop and the transit speed decrease while the fast lane speed increases.This result could help calculate the transit delay correctly and make arrangements for transit routes reasonably and scientifically. 相似文献

Analysis of the influence of occupation rate of public transit vehicles on mixing traffic flow in a two-lane system 下载免费PDF全文
Based on the existing classical cellular automaton model of traffic
flow, a cellular automaton traffic model with
different-maximum-speed vehicles mixed on a single lane is proposed,
in which public transit and harbour-shaped bus stops are
taken into consideration. Parameters such as length of cellular
automaton, operation speed and random slow mechanism are
re-demarcated. A harbour-shaped bus stop is set up and the vehicle changing
lane regulation is changed. Through computer simulation, the
influence of occupation rate of public transit vehicles on mixed
traffic flow and traffic capacity is analysed. The results show that
a public transport system can ease urban traffic congestion
but creates new jams at the same time, and that the influence of
occupation rate of public transit vehicles on traffic capacity is
considerable. To develop urban traffic, attention should be paid
to the occupation rate of public transit vehicles and traffic
development in a haphazard way should be strictly avoided. 相似文献
