Version 3 of the Sydney Strategic Travel Model (STM3) incorporates a wide range of behavioural choices, but the model does not explicitly represent time period choice. BTS are considering whether the mode-destination models within STM3 should be extended to model time period choice. Therefore a review of time period choice modelling literature was undertaken with two objectives. First was to undertake a broad review of the time period choice literature to understand how researchers and practitioners have modelled time period choice, and the practical lessons learnt from those studies that have implemented time period choice in a strategic model. The second more targeted objective was to provide recommendations on how to incorporate time period choice within the current Sydney Strategic Travel Model.
