A1. When putting transport analysis into practice and when making choices on transport measures for travel plans various information sources will be useful. Those of particular relevance are set out below.
A2. Origin-Destination Statistics provided by the Census attempt to analyse flows of people, for example travel to work. Such data can then be expanded on to include the method of travel and age patterns. Of particular use would be the following data sets: Standard Tables, Census Area Statistics and Special Travel Statistics.
The Scottish Household Survey
A3. This survey of around 15,000 households per year across Scotland aims to provide accurate and up-to-date information on characteristics, attitudes and behaviour of Scottish households and individuals on a wide range of issues. Particular sections provide information on travel and transportation, for example household car availability; cycling, walking and use of public transport; travel to work and school. The survey also collects "travel diary" information. Results are available annually for the larger local authorities, and every 2 years for all authorities. These are based on interviews with a minimum of 500 or so households in each authority in each two-year period. Local authorities can obtain anonymised copies of the SHS data from COSLA, and the data are also deposited at the UK Data Archive.
A4. The SHS's transport-related results are published in three series of statistical bulletins:
- Household Transport - main results for Scotland;
- Transport across Scotland - main results for local authority areas;
- SHS Travel Diary results - includes some figures for local authority areas.
These are available from the Stationery Office Bookshop and the Scottish Executive Web site. For information or questions on Transport, contact Transport Statistics: Tel: 0131 244 1457.e-mail: email@example.com.
Scottish Transport Statistics
A5. This annual report looks at the trends over the last 10 years and provides information on different modes of travel (for example road, rail and air). It also provides specific statistics on related topics such as finance and injuries. Most of the figures relate to Scotland as a whole: only a few tables provide figures for local authorities. Copies are available from the Stationery Office Bookshop and it can also be found on the Scottish Executive Web site.
A6. This is a database containing site and development information for some 1,800 development sites in the UK. In each of these developments traffic entering and exiting is recorded, and from this information trip rate calculations are carried out, which can be used to estimate traffic flows for a variety of development types. This is becoming increasingly useful as it focuses less on traffic and more on multi-modal transport.
Local Travel Information
A7. In the preparation of Development Plans and Regional and Local Transport Strategies travel surveys will be undertaken by local authorities. They may be for the whole area or site specific. Collating and monitoring details of travel plans may also provide good base line data. Such information also enables comparisons to be made between sites in an area dependent on local circumstances. These are a valuable source of local information which can be utilised.
A8. Local authorities are not alone in collecting data on travel characteristics. Other agencies may be of assistance on more detailed aspects of travel, for example: neighbouring authorities, rail and bus operators, port authorities, Civil Aviation Authority, local businesses, walking and cycling groups, disability groups.
A9. Research completed at both a national and local level will provide useful information as will case studies where similar work has been undertaken elsewhere.
