ETIS+ TRANSTOOLS 3 link

• ETIS+ will be the most important data source for TRANS-TOOLS3

• In general very valuable data (hopefully) • But,… modellers have almost infinite desires for data

–Therefore also some data work in TRANSTOOLS3

TransTools 3 - Overview

• 3 year project, lead by DTU Transport• 2011-2013 (1/3 2014)• 1.95 Million Euro• Improve and upgrade TransTools• Will heavily build upon the new ETIS+ data• Re-estimate the model to 2010 data

TransTools 3 – Model interface

• Different purpose specific configurations of the model

– Fast for strategic purpose– Mode and sector (passenger/freight) specific configurations– Detailed (slow) version

• Two user interfaces– Simpler stand alone interface with predefined configurations– A detailed ArcGIS Modelbuilder-based for full control and flexibility

in model design

• =>Three model usage levels– Planners (pre-defined set-up)– Experts (changing configurations, parameters, filter criterias,…)– Researchers (changing utility functions, functional forms, stochastic

elements, statistical distributions,…)

TransTools 3 – Main Modelling tasks• Re-estimate passenger demand models• New freight and logistic models

– Including containerized transport• Tuned solution algorithms for traffic assignment (network

models)• Merged rail networks and new rail assignment models

TransTools 3 – Geography

• Geographic scope– Extension of air transport model to include

intercontinental flights– Extension of freight models to intercontinental freight

• Geographic resolution– More homogeneous zone system

• Merge very small zones• Split very large zones

– Explicit handling of main terminals• Rail freight terminals• Stations• Harbours• Inland waterway harbours• Airports

Some general success criteria for TT3

• Shorter run times, and (much) better convergence (less stochasticity)

• More thorough validation–Special WP (½ year only for validation)– Internal and external review and validation process

• Better documentation–Scientific documentation report–Validation report–User guide
