Transportation modelling software is a handy tool with respect to transportation planning. Admittedly, any practitioner needs to be careful that models are applied properly, based on good data and reasonable assumptions. As the old adage goes – garbage in, garbage out – if one fails to apply models properly. Are models perfect? Of course not, but they are still beneficial to the planning process.
Over the past several decades, transportation models have evolved tremendously from pen-and-paper plots and computer mainframe processing to microsimulation models with car-following algorithms on multiple processor computers. So to have the uses for transportation models evolved over time. Continue reading
