Stage 1: Assessing the Travel Characteristics of a Development: Estimating modal split
Modal split estimates can draw on catchment area analysis, comparing travel behaviour with activity elsewhere and supported by data on the likely travel behaviour. However, it may be possible to make good estimates with less emphasis on these techniques by comparisons with similar existing developments, and including the effect of proposed measures to influence travel in the proposal. In seeking suitable sites, one should look for comparable locations, scale, public transport provision and non-car accessibility.
Using these techniques should provide estimates of the numbers travelling to the site, their choice of mode, and the overall modal split.
Realistic estimates of access by non-car modes should be provided.
