17.2.2 TEMPRO and the National Trip End Model (NTEM)

TEMPRO is a computer program used to access the National Trip End Model forecasts of growth in person trips on most modes of surface transport, and the underlying car ownership and planning data projections. TEMPRO enables the user to retrieve data for any year from 1991 through to 2041, and calculate the growth rate between a selected base and future years.

The ‘NTEM zoning system' divides Great Britain into around 2,500 zones. In Scotland (region) the zoning system is broken down into local authority areas and zones. Settlements under 10,000 population are generally not distinguished as separate zones but are included within the rural area (if any) of each Local Authority.

Sources:

The main sources of information contained within TEMPRO are:

• Census 2001;
• Mid-year population estimate and Office for National Statistics (ONS) population projections;
• Office of the Deputy Prime Minister (ODPM) housing projections;
• Inter Departmental Business Register and Annual Business Inquiry (ABI) employment data; and
• Regional planning bodies.

Data Availability:

Data can be output from TEMPRO/NTEM at a Great Britain, local authority and zonal level. In addition, data can be output for a user defined study area, made up of one or more counties and/or zones.

The following base and forecast data can be output:

• Total Trip Ends;
• Trip Ends split by Purpose (Home based work, non-home based work, employer's business, personal business, education, shopping, recreational/social, visiting and holidays/day trips);
• Trip Ends split by Time Period (weekday am peak, inter-peak, PM-peak, off-peak, Saturday, Sunday, average weekday and average day);
• Trip Ends split by Mode (walking, cycling, car driver, car passenger, bus/coach, rail/underground);
• Trip Ends split by Car Availability;
• Number of Households with 0, 1, 2, 3+ cars;
• Total Households;
• Total Cars;
• Population;
• Workforce; and
• Jobs.

The format of trip end forecast data is available as:

• Growth Factors ( = future year data/base year data);
• Future Year - Base Year ( = growth expressed in terms of the absolute increase/decrease in the displayed data values);
• Base Year Data ( = absolute data for the selected base year); and
• Future Year Data ( = absolute data for the selected future year).

Format of the data:

TEMPRO is a WINDOWS based program. Exported data is in comma separated variable (csv) format.
