Regional Trip Rates Variation in TRICS Owen Edwards Consortium
Past research by Owen Edwards Consortium on trip rates variation in TRICS regions led to the initiation of a new research phase to confirm or confront previous findings. The importance of factors like location type, local population, and vehicle ownership in determining regional selection was highlighted. True compatibility in site and development data was emphasized over the exclusion of regions to ensure accurate site selection.

REGIONAL TRIP RATES VARIATION IN TRICS OWEN EDWARDS TRICS CONSORTIUM
Often brought up by users requesting guidance on trip rates survey samples Basic regional variation research was carried out in the past OWEN EDWARDS TRICS CONSORTIUM
Previous work suggested less regional variation than generally assumed TRICS would like to confirm or confront previous findings OWEN EDWARDS TRICS CONSORTIUM
New research split into two phases leading to a final technical note Initial phase to look into trip rates across a variety of popular land uses OWEN EDWARDS TRICS CONSORTIUM
CURRENT GOOD PRACTICE GUIDANCE OWEN EDWARDS TRICS CONSORTIUM
Regional selection is not as important a factor as location type and other important factors The importance of compatibility in terms of local population, vehicle ownership, location type, etc, cannot be stressed enough OWEN EDWARDS TRICS CONSORTIUM
No obvious reason why some data from Glasgow cannot apply to some data from Greater Manchester Similarly, some site scenarios in parts of London may be compatible with sites in other large cities OWEN EDWARDS TRICS CONSORTIUM
It is in the areas of site and development data where true compatibility should be sought, rather than just through the exclusion of regions, which could unnecessarily remove many compatible sites from a user s selected set OWEN EDWARDS TRICS CONSORTIUM
TRICS REGIONS OWEN EDWARDS TRICS CONSORTIUM
1 Greater London 2 South East 3 South West 4 East Anglia 5 East Midlands 6 West Midlands 7 Yorkshire & North Lincolnshire 8 North West 9 North 10 Wales 11 Scotland 12 Connaught 13 Munster 14 Leinster 15 Greater Dublin 16 Ulster Ireland 17 Ulster Northern Ireland OWEN EDWARDS TRICS CONSORTIUM
GROUPED REGIONS OWEN EDWARDS TRICS CONSORTIUM
Number of surveys in each TRICS region varies massively Where possible, similar regions are grouped together to see how these results compare to the rest OWEN EDWARDS TRICS CONSORTIUM
Certain regions were grouped together for calculating trip rates 5 East Midlands, 6 West Midlands ---------------- 7 Yorkshire & North Lincolnshire, 8 North West, 9 North ---------------- 12 Connaught, 13 Munster, 14 Leinster, 15 Greater Dublin, 16 Ulster Ireland, 17 Ulster Northern Ireland OWEN EDWARDS TRICS CONSORTIUM
Using grouped regions results in six major regions to focus on 1 Greater London 2 South East 3 South West 5-6 Unified Midlands 7-9 Unified North 12-17 Unified Ireland OWEN EDWARDS TRICS CONSORTIUM
LAND USES OWEN EDWARDS TRICS CONSORTIUM
Most popular land uses selected 01/A Food Superstore 02/A Office 03/A Houses Privately Owned OWEN EDWARDS TRICS CONSORTIUM
01/A Food Superstore split into Friday only and Saturday only surveys 02/A Office and 03/A Houses Privately Owned will use only weekday surveys OWEN EDWARDS TRICS CONSORTIUM
SELECTION PARAMTERS OWEN EDWARDS TRICS CONSORTIUM
As many surveys wanted to keep the samples as large as possible Vehicles Only surveys Looking at surveys from the past 20 years, minimum date set to 01/01/1999 All location types included OWEN EDWARDS TRICS CONSORTIUM

Different land uses give significantly different results For these data samples regions can be top of a ranking for one land use but bottom of a ranking for another OWEN EDWARDS TRICS CONSORTIUM
Rather than regional variance, other important factors such as location type, public transport levels, local population, car ownership can be much more significant All these are adjustable parameters within the TRICS software OWEN EDWARDS TRICS CONSORTIUM
Using the four data samples, it is possible to view each major region s variance ranges from the average of all surveys The two tables are based on total peak figures and total trips figures OWEN EDWARDS TRICS CONSORTIUM
