Abstract: | 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. |
