  1. EMME Users’ Group MeetingNSW Modelling Guidelines - Highway Assignment27 May 2011

  2. PROJECT SCOPE • Highway Modelling Techniques • Not Prescriptive or Detailed • Summary of Relevant Standards and Guidelines • Meso and Macro Level Models only • Topics were set at a workshop with RTA and BTS reps

  3. Key References • Traffic Modelling Guidelines, TfL Traffic Manager and Network Performance Best Practice, Transport for London. • Guidelines for Selecting Techniques for Modelling Network Operations, AustroadsResearch • Design Manual For Roads and Bridges, DOT (UK) • Economic Evaluation Manual. NZ Transport Agency. • A Primer for Dynamic Traffic Assignment. TRB

  4. Draft guideline contents • Model type selection using a suitability scoring method suggested by Austroads • Review the project context • A preliminary analysis to establish the need for modelling and to refine the functional specifications for the model solution. • Review the elements of the traffic system relevant to the functional specifications using a worksheet of suitability scores. • Assess the various model types by adding up the suitability scores.

  5. Draft guideline contents (cont) • Model scope and specifications • Model software • Broad model development procedure • Network familiarisation • Data acquisition • Typical traffic conditions • Traffic surveys • Passenger Car Units • Signal phasing and timing data • Bus vehicle and bus lane usage

  6. Draft guideline contents (cont) • Scale of study area and network • Zones, nodes, connectors and links • Intersection coding • Representation of tolls • Demand matrices • Assignment • Blocking back • Convergence • Base model calibration and validation • Scenario modelling and reporting

  7. Timing • Preliminary draft is currently with RTA • Workshop with RTA & BTS (within 2 weeks) • Final draft to RTA (mid June) • Full guideline draft for initial use and comment
