The National Origin-Destination Transport Survey Project has been developed by the DfT to assist organisations involved in the identification, selection and use of appropriate origin-destination transport data. Collection of this type of data is often expensive. For this reason, whenever possible, transport modellers should ensure that they make the best use of existing survey data. However, it is often time-consuming identifying potential sources of movement data and can cause duplication of effort.
In recognition of the need for a consolidated source of information, the National Origin-Destination Transport Survey project was developed by the DfT in association with the Highways Agency. The project originally began in 1997 and has undergone a number of changes since then.
Sources:
The National Origin-Destination Databank now contains information about transport origin-destination surveys for:
The resultant database contains information collected from questionnaire returns sent to local authorities and consultants covering England, Scotland and Wales. The database contains information on the location and type of data available, including organisation central contact details.
Data Availability:
The database provides a list of site locations for existing RSI datasets held by UK public authorities, including summary data (contact name, telephone number, date of survey etc.).
Public transport survey sites are represented in the mapping application as location-based, route-based or area-based, depending on the surveying methods.
Home interview surveys are represented on an administrative boundary level so when a user selects an area they are presented with a listing of all surveys taken.
Format of the Data:
Outputs from the datasets can be spreadsheet listings, printouts of GIS maps, or a GIS point dataset. Detailed maps showing site locations are also available.
Data Use:
The National Origin-Destination Databank contains details of what RSIs have been carried out to date, along with their locations and date of survey etc. The information can be used to augment local RSI survey data during matrix building.
Accessing Data:
The Database File, Index Files and Survey questionnaires can be downloaded from the DfT website: http://www.dft.gov.uk/pgr/econ
