Transport Assessment
Data Available in Northern Ireland

For those undertaking a Transport Assessment the type of analysis required will vary between proposed developments.
Data is of variable quality, with much depending on the type of area in which a development is proposed and the resources available to the developer undertaking the assessment. Data exists to analyse and predict modal split, but it may require significant resources and expertise to analyse, and the accuracy of forecasts may be unreliable.
Existing data sources will adapt over time to include additional data, and new data sources may be created so that in future developers will be able to draw on a wider range of information than currently exists.
Data on travel behaviour from which modal split predictions might be made is good at the national level, but only at the level of trip making for different journey purposes.  For journeys by non-car modes to specific developments (especially ‘new types’ of development such as multiplex cinemas) data is poor.
