Fixed time or variable: does it matter? [Microsimulation modelling]
Microsimulation modelling is a tool that is able to guide the decision making process at various stages of a project, from concept, pre-planning, environmental impact assessments, development applications, detailed design through to final construction approval. In the development, coding and building of models, there are many input variables that have an impact on the outcome of the model. Traffic generation characteristics, mode choice, parking provision, distribution, and driver behaviour are examples of such inputs into models that play a significant role in the model outcome. One such key input is signal control. Microsimulation models can include basic and/or complex signal control set-ups including fixed timing, vehicle actuation and third party variability such as SCATSIM. Is it possible to arrive at the same outcome with each of the differing signal control? This paper demonstrates that the network results for two models may differ with each type of control, however will it change the answer that the model provides? This paper discusse some of the requirements for developing models and queries the impact that differing levels of assumptions and inputs can have to the model outcome.
