17.2.1 Summary

In general, all the UK data sources are held by the Department for Transport (DfT) and all the Scottish sources by the Scottish Government.

United Kingdom Transport and Travel Databases

The DfT has a number of national data sources including:

• TEMPRO Planning Data - National Trip End Model (NTEM);
• National Travel Survey (NTS);
• Census Journey To Work (JTW) trip matrices;
• Rail Passenger Trip Matrices (station to station) from LENNON; and
• National Index and Depository of Roadside Interview Survey Data;
• Traffic counts (see SRTDb summary for details).

Summaries of these national data sources are included in this Appendix.

Scottish Transport and Travel Databases

In addition to the national data sources outlined above, there are also a number of Scottish Government data sources and other Scottish based data sources available. These can be categorised under the following headings:

• Network (Supply) Data;
• Travel (Demand) Data; and
• Combined Network/Travel Data.

Network (Supply) Data

Network (Supply) Data includes:

• Road Network descriptions (links, junctions, tolls);
• Public Transport Services (routes, frequencies, capacities);
• Parking data (on/off street, short/long term, spaces by location); and
• Zones - land-use areas (e.g. shopping/employment centres, residential estates).

Sources of Scottish Network (Supply) Data include:

• Road Accidents Scotland;
• TREAD - Trunk Road Economic Assessment Database; and
• Public Transport timetables - Traveline Scotland.

Travel (Demand) Data

Travel (Demand) Data includes:

• Trip End data (based on car ownership/land-use planning data);
• Trip Distribution data (private/public transport origins to destinations); and
• Traffic/Passenger Count data (traffic flows by vehicle type, public transport passenger volumes by service / location).

Sources of Scottish Travel (Demand) Data include:

• SRTDb - Scottish Road Traffic Database, maintained by Transport Scotland;
• Scottish Household Survey (SHS);
• Scottish Transport Statistics (STS);
• Bus & Coach Statistics; and
• Public Transport Survey & Ticket Data.

Network/Travel Data Combined

In addition to the above sources comprising Network or Travel Data, there are sources which contain both, including:

• Land-use and Transport Integration in Scotland (LATIS); and
• SITM -  Strathclyde Integrated Transport Model.

Land Use and Services Databases

To allow transport supply and demand to be considered in relation to the spatial pattern of land uses and services, for example in the accessibility analysis, national and local data may be needed. These include:

Locations where jobs, education and training are available;

• Locations where health services are provided;
• Locations of shops; and
• Other opportunities which may be of local significance such as post offices, chemists, leisure opportunities, banks and building societies.

Table 17.1 summarises the transport data contained within the various sources detailed in this section.
