1 Getting on the MOVES: Using Dynameq and the US EPA MOVES Model to Measure the Air Pollution Emissions TRPC – Smart Corridors Project Chris Breiland Fehr & Peers September 16, 2011

2 Outline Project Overview, Background and Objectives Dynameq Model Development Estimating Air Pollution Emissions Motor Vehicle Emission Simulator (MOVES) Comparison Conclusions Q&A

3 TRPC - intergovernmental board made up of local government jurisdictions County area sq miles population - 245,300 The county’s population is expected to be 373,000 in 2030 The county is the home of the State’s Capitol, City of Olympia Overview

4 Project Background Congestion Mitigation and Air Quality (CMAQ) grant Options to reduce PM10 through ITS deployment – coordinated signal timing and optimization – transit signal priority (TSP) Two strategic corridors were chosen from the Regional Transportation Plan (RTP) that are problematic for Intercity Transit’s on-time performance goals

5 Study Corridors

6 To improve multi-modal transportation operations on the two corridors To evaluate signal coordination and optimization To evaluate transit signal priority options To reduce PM10 (particulate matter) emissions in the corridors. Project Objectives

7 NETWORK –Entire network brought into DTA model from EMME Travel Demand Model –Refined the Dynameq network to add missing intersections on the corridors –Modified all centroid connectors for the zones around two corridors to reflect field conditions –Verified link attributes –Network properties in DTA model: – 800 centroids – 2,500 regular nodes – 8,000 links – 20 transit lines TRIP TABLES –Trip tables brought from EMME Travel Demand Model –The modes are SOV, HOV & Truck Model Development

8 INTERSECTION CONTROLS –Focused on corridors and a several-block buffer –81 signals & 67 stop controlled intersections INTERSECTION GEOMETRY –Approaches to the intersections were modified to reflect field conditions –Added right and left turn lane pockets where needed

9 Model Development Validation / Calibration –Validated and calibrated the existing year model (study corridors and I-5 primarily) Based on link counts Based on turn move counts Based on travel time on corridors –Queuing at hot spots

10 Model Validation

11 Air Pollution Emissions and Model Detail Air Pollution Highly Sensitive to: VMT Speed Vehicle Type Drive Cycle DTA versus Static Models

12 How are Emissions Estimated? Air Quality Analysis tools – EMFAC, Mobile6, MOVES

13 Motor Vehicle Emission Simulator (MOVES) State-of-art tool for estimating emission from highway vehicles developed by US Environmental Protection Agency (EPA) Highly detailed Perfect for Dynameq

14 MOVES Input Data Data needs from Dynameq DTA Model Link

17 OpMode Uh-oh!

18 OpMode Uh-oh!

19 New Component for Dynameq to Extract the Necessary MOVES Input Data

20 OpMode 300,000 rows

21 Emissions Calculation Comparisons 2010 Base VMTPM 10 (g)CO 2 (g) EMME + EMFAC 25,2101,30912,420,539 EMFAC 30,029 2,22417,883,106 Mobile61,28216,591,022 MOVES99717,051,387

22 Concluding Thoughts MOVES is new standard MOVES is built for a tool like Dynameq INRO Dynameq-MOVES component enables analysis MOVES very difficult to run
