Research Abstract
This study provides a methodology to incorporate the dynamic bus stop simulation into a proposed static
transit assignment model. It tries to combine the merits of
the realism of dynamic models and the simplicity of static
models in a single framework. An algorithm is developed
to simulate any load profile of both passenger and bus
arrivals. Then, the simulation results are used within the
transit assignment process to allow a better line choice
representation. A detailed illustrative example is given to
validate the proposed assignment methodology performance. The resulted flows in some cases exceed lines
capacity while conserving the static equilibrium principles.
This capacity violation interprets the fact that some passengers may fail to board the first incoming bus of their
desired line due to insufficient capacity. However, they
wait until a vacant space is offered on the same line. In
addition, a benchmark problem is solved to ease the
comparison between the proposed methodology and the
existing methodologies. It shows the methodology capability of incorporating different waiting time models to
produce passengers’ flow on transit lines. It also indicates
the importance of lines that might be neglected in other
transit assignment models. This would highlight the
methodology interpretation of passengers’ behavior in
transit networks.
