Traditionally, there has been a general lack of bus-based origin-destination data for TMfS and indeed for other transport models. As a result, the collection of such data for Aberdeen, Dundee, Edinburgh, Glasgow and Inverness was seen as important in improving the public transport element of the new national model. Given that these were inter-urban surveys, the data also provided valuable data for a range of other important towns including Stirling, Falkirk, Dunfermline, Livingston, Ayr, Kilmarnock and Cumbernauld.

An initial desk based review of timetables and routes was undertaken to identify where data collection was required and a cordon was defined around each city designed to capture all bus-based movements into and out of the urban area. Passenger interviews and accompanying occupancy survey were conducted between 7am and 7pm on a typical weekday. The collected origin-destination data was processed and demand matrices prepared suitable for incorporation in the national model.

Please refer to the Public Transport Model Development Note 2 - Inter-Urban Bus Processing for the analysis of the survey data and the preparation of demand matrices.
