1 Oregon Statewide Integrated Model
Title slide option 1 Overview of Version 2.5 OMSC Modeling Program Coordination Committee Presented by: Becky Knudson, Senior Transportation Economist Transportation Planning Analysis Unit, ODOT April 19, 2017

2 Outline New Features Peer Review Application SWIM 2.5

3 SWIM Schematic

4 Why 2.5… 4. SWIM assignment with VISUM 2. Refined Economic Module
5. Generalized Transit 2. Refined Economic Module 3. New Commercial Travel Mode 1. Replaced PI module with PECAS-AA

6 PECAS AA Production, Exchange, Consumption Allocation System - Activity Allocation Module Spatial input-output model Integrated representation of spatially distinct markets Represents how activities of households, industries, business and government locate Location determined by developer space Location responsive to how activity interacts with each other Pricing mechanism clears markets Steps through time

7 Model area forecasts for output and employment
NED New Economics & Demographics Module Model area forecasts for output and employment Produces outputs by AA Activity, inputs & outputs, population in 5 yr age groups Uses DAS IHS-Global Insight forecast used for official revenue forecast

8 Generates freight flows for model area based on AA Module
CT Commercial Travel Module Calibrated to traffic counts Generates freight flows for model area based on AA Module Uses FAF data and Rail Waybill

9 CT Original recipe

10 CT Updates in place Revise using FAF4 OD data
and updated border truck counts

11 TS To VISUM Transport Supply (TS) replaced with VISUM
Highway and transit skimming and assignment Microsimulated trip subarea analysis Networks already maintained in VISUM All spatial input data managed by VISUM (zonal, highway and transit) Simplification of transit network representation No longer managing local bus networks Modeling local bus LOS with local transit functions borrowed from the California STDM Various revisions to process requested by ODOT

12 Generalized Transit Calculates local transit in-vehicle time and out-of-vehicle time skims Based on California Statewide Travel Demand Model local transit functions (LTF) Builds transit connectors to premium network using LTF matrices The Transit Assignment process reads transit demand data created by the previously run SWIM modules and assigns it to the transit network managed in the version file. In the process, various skims are created (time, wait, cost, etc.), as well as assignment results and reports. The module does not have a local transit network. Instead, it calculates local transit in-vehicle time and out-of-vehicle time skims according to the California Statewide Travel Demand Model Local Transit Functions (LTF). This step also builds transit connectors to the premium network using the LTF in-vehicle time and out-of-vehicle time matrices from the zone centroid to the zone of the nearest X transit stops. Finally, it adjusts the intracity skims so only the skimmed skims or the LTF skims are available for an OD pair.

14 Applications and Peer Review
On the same page because we did these simultaneously Applications and Peer Review

15 SWIM 2.5 Peer Review Frank Koppelman, Northwestern University, retired
David Simmonds, Simmonds & Assoc, Cambridge England Michael Wegener, Univ. of Dortmund, Germany Keith Lawton, Oregon, formerly Metro Julie Dunbar, Dunbar & Associates Kim Fisher, Univ. Of Maryland, formerly TRB Bill Upton, Oregon, formerly ODOT SWIM 2.5 Peer Review

16 Panel Topics SWIM 2.5 performance Use for applications
Refinement suggestions Lessons learned SWIM 2.5 Becky: ODOT wants this from Panel

17 Oregon’s Economy Relies on Freight Movement
History of analysis: RRA1 arose from a question prompted by a Minnesota study… We used SWIM 2.0 and had no bridge deterioration model, was an exploratory analysis to understand the potential risk to the economy. RRA2 refines the analysis, using better tools with more information – yet a major reveal was the need for more data… We included a TAC to refine the outreach and messaging aspects. 2014 2017
