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

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

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

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

CAPITAL - Software / Applications

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)

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

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

Demonstration of CAPITAL

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

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

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
