1. Combining EMME/2 and ArcView GIS: The CAPITAL Model Case Study

2. Introductions Richard HopkinsTransport for London (TfL) Nigel RobbinsBrown & Root David JamesBrown & Root

3. CAPITAL Presentation Overview s Purpose of Presentation s What is CAPITAL? s Software/Applications s The Calculator  Overview  Key Components  Stages of the Calculator s Examples of output

4. Purpose of presentation s What is CAPITAL? s What is Railplan? s The EMME/2 and GIS approach

5. definition C alcul a tor (for measuring) P ubl i c T ransport A ccessibility in L ondon What is CAPITAL?

6. s To provide a planning tool for calculating detailed and accurate measures of real ‘clock’ travel time accessibility, from an area, to a specific location (or the reverse movement). e.g.  Town centres  Development sites  Hospitals  Supermarkets

7. CAPITAL - Software / Applications

8. Software Overview s Emme/2 - Railplan s ArcView GIS s Network Analyst Reporting Queries Customised Interface ArcView 3.2 ( + Network Analyst ) GIS CAPITAL Model ArcView 3.2 ( + Network Analyst ) GIS CAPITAL Model Database tables TfL Spatial Layers and Base mapping layers Data transferred into emme/2 (via macros) Data transferred into GIS (via ASCII files)

9. Railplan PT model s EMME/2 software s Strategic ‘PT Network/Assignment’ model  Stations, TOC, LUL, DLR, Bus services/network  Amended zoning structure

13. Example of Origin and Destination selection OSCAR network ED boundary ED Centroid Railplan zone Railplan network Railplan nodes (Selected within buffer) Buffer Area Min.Cost route(s)

14. Railplan zone and Census ED boundaries OSCAR network ED boundary ED Centroid Railplan zone Railplan network Railplan nodes (Selected within buffer) Buffer Area Min.Cost route(s)

15. Railplan zone and Census ED boundaries (+ OSCAR links) OSCAR network ED boundary ED Centroid Railplan zone Railplan network Railplan nodes (Selected within buffer) Buffer Area Min.Cost route(s)

16. How does CAPITAL link the walk and PT networks? s Bus and Light Rail Stops s Station Entrances s PT access/ egress points are the key link between GIS and Railplan  SAP - S ervice A ccess P oint  SEP - S ervice E gress P oint

18. Demonstration of CAPITAL

19. Demonstration s Simple ‘Windows-style’ interface s Menus linked to CAPITAL processes s Management of the Railplan scenarios s Show how SAPs/SEPs imported into the GIS s Create a walk file s Specifying a CAPITAL ‘run’ linking with Emme/2 s Results shown in GIS

20. Achievements s Improved performance s Improved network modelling capability s Modelling of Walk access and egress with improved algorithm for egress s Multiple destinations s Choice of access/egress mode speeds s File management structure based on projects

21. Next steps..?? s Tools to display route choice s Multi-modal networks (cycle, car etc) s Improved management of SAPs/SEPs via Emme/2, including node specific penalties s extend access modes (e.g. cycle, car etc) s integrate CAPITAL the Planning Information Database for TfL. s Modelling of mobility impaired access/journeys
