Local Use of TRICS: A Case Study from a User’s Perspective

1. Ewan Anderson, Fore Consulting Limited Local Use of TRICS: A Case Study from a User’s Perspective

2. Contents • Two examples of recent projects: • Harlow Grange, Harrogate (124 dwellings). • Clifton Gate, York (3,400 dwellings). • Look at where TRICS works well and where it is currently limited. • Is TRICS appropriate when working on large/strategic sites? • Some questions for TRICS (and users) going forward.

3. Project 1: Harlow Grange, Harrogate

4. Overview • Proposed development of 124 residential dwellings. • Approximately 3.0km southwest of Harrogate Town Centre. • Immediately north of B6162Otley Road.

5. Use of TRICS • TRICS used to derive average person trip rates (‘Multi-Modal Total People’) for the proposed development. • Database interrogated for sites based on the following criteria:

6. Use of TRICS • Estimation of vehicular trip rates: • Person trip rates from TRICS applied to the car driver mode share for the local ward. • Harlow Moor ward (‘Method of Travel to Work’, 2011 Census) = 64%. • TRICS is considered to work well for projects of this type. • Large number of similar sites available. • Options to tailor search criteria to match proposed development.

7. Project 2: Clifton Gate, York

8. Overview • Located: • North of the A1237 Outer Ring Road at Clifton Moor. • Approximately 5.0km northwest of York City Centre. • 140 hectares of land.

9. Overview • Proposed development of 3,400 residential dwellings. • A draft allocation in the City of York Local Plan. • Sustainable new settlement, including: • Local facilities. • Social infrastructure. • Convenience retail. • Park & Ride and regular bus service to city centre.

10. Use of TRICS • Used the same approach to deriving person trips rates as for the previous example. • Provides similar search criteria: • Residential, Houses Privately Owned, Edge of Town, etc. • However, very few large residential sites within TRICS database. • Comparison of vehicular trip rates between the two projects:

11. An Alternative Approach • Origin-Destination Survey of proxy area. • ANPR cameras covered all vehicle routes into Haxby and Wigginton. • Excluded ‘through’ traffic movements. • Counted all residential dwellings. • Site (Red) • Proxy (Blue)

12. Comparison of Trip Rates

13. Issues from the comparison • Does the use of TRICS accurately provide trip rates for large/strategic developments, at present? • If not, can TRICS respond to this challenge moving forward, or do we need to adopt a different approach to deriving trip rates for these sites? • For example, by desegregating trips by journey purpose.

14. A Local User’s Perspective • Increasingly working on more large-scale, strategic sites. • Brought about by changes to the national policy framework. • Changes to planning policy through NPPF. • DfT Circular 02/2013 • Sites being promoted through the Local Plan process. • If not, does the use of TRICS become a barrier to development? • Overestimating the traffic generation and traffic impact on the highway network. • Extent of study area to be assessed. • Mitigation schemes required.

15. Questions for TRICS going forward • Does TRICS need to expand its database to include more large/strategic sites? • If so, how feasible is the collection of accurate data for these sites? • The internalisation of trips. • Multi-modal trip rates. • Phasing and build-out (10- years). • And how can these sites be integrated into TRICS?
