The assessment of transit oriented developments using microsimulation models

Liveable and sustainable cities are the key focus of urban planning in the twenty-first century, leading to policies to reduce car use, increase the model share of public transport and promote sustainable forms of transport. High-density mixed-use developments are a common and convenient design option, integrating sustainable modes of transport. Assessment and comparison of transit oriented developments (TODs) can improve existing areas, determine the best approach and allow better urban designs in the future. This chapter looks at some existing ways in which to assess a TOD, briefly examining progression of assessment methods, various indicators available, and methods currently used by academics and within the urban and transport planning industry. Following this, microsimulation modelling is introduced as an additional concept that could be used to assess TODs using vehicle, pedestrian and combined microsimulation models. The role of visual presentation of results can help to sway policy-makers and stakeholders. With no existing TOD modelling criteria or guidance, there is scope for these to be developed by stakeholders, experienced modellers and members of the academic community. Sustainability is a key agenda in most environmental and government strategies, providing a holistic assessment method would enable faster improvements to urban areas.
