ABSTRACT: A lane exclusively for transit is one measure to reduce urban congestion
and intelligent transportation systems (ITSs) are expected to make this policy
more effective. However, the advantage may be limited if a transit agency does
not provide sufficient vehicles. This study
evaluates the effect of transit capacity on a dedicated transit lane
policy by examining the morning commute problem, by defining user equilibrium
and system optimisation considering transit capacity. It was confirmed that
reduced transit capacity under user equilibrium smoothly increases the transit
cost per person, which decreases the duration period of the dedicated transit
lane and increases the number of early and delayed car commuters. However, the
effect of reducing transit capacity under a system optimum depends on the
initial solution of the system optimum.
