Installation instructions

These are also included in the MOVES2010InstallationSuite, as readme.txt.

The MOVES Installation Suite (Suite) will install MOVES2010 on your computer. MOVES2010 is a 32-bit application that may be run with the following operating systems: Windows 2000, XP, Vista, Windows 7, 2003 server and 2008 server.

Changes in this Revised Suite

This Suite includes a fix of 'Path not found' error found on machines running 32 bit Windows 7 operating systems. An enhancement was added to search for the MOVES java application and update its installation status. In addition, this Suite can fine-tune MySQL for better MOVES performance if the user clicks on the "Tune MySQL" button in the Setup MySQL 5.1.32 tab. No changes were made to the MOVES code or default database.

Note that if you have successfully installed the MOVES2010 system using the previous version of MOVES2010 Installation Suite (released in Dec. 2009), MOVES2010 should continue to run well without the use of this revised installation suite. However, we recommend you use this revised suite if you reinstall or modify the MOVES2010 system.

6. Copy the MOVESDB20100515 folder to your MySQL Data folder. The MySQL Data folder is likely located at
   c:\MySQL\data, unless you chose a different location when you originally installed MOVES.
7. Find the MOVES MOVESConfiguration.txt file. For most installations this should be located in the folder c:\Program Files\MOVES20091221. For Windows 7 and Windows VISTA users, this folder may be in the c:\Users\Public folder, in the Program Files (x86) or in the Program Files folder.
8. Open the MOVESConfiguration.txt file with text editor such as Notepad. On the second line, change in the line from defaultDatabaseName = MOVESDB20091221 to defaultDatabaseName = MOVESDB20100515. Save the file.
9. To confirm that the database has been installed correctly, launch MOVES. In the top menu bar of the GUI window, click on Settings, then Configure MOVES. You should see MOVESDB20100515 in the Default Database window.
10. When you run MOVES, the default database is reported in the output database. The movesrun table includes the field “defaultDatabaseUsed” that identifies the default input database used for each run.

Background Reports

• Proof of Concept Investigation for the Physical Emission Rate Estimator (PERE) to be Used in MOVES (PDF) (82 pp, 2.4MB, EPA420-R-03-005, February 2003) This report provides a proposal for the Physical Emission Rate Estimator (PERE) to be used in MOVES. By Dr. Edward Nam of Ford Motor Company
• An assessment of methods for developing emission rates based on the results on the on-board shootout discussed below is documented in Methodology For Developing Modal Emission Rates For EPA's Multi-Scale Motor Vehicle & Equipment Emission System (PDF) (286 pp, 1.09MB, EPA420-R-02-027, August 31, 2002) produced by North Carolina State University.
• An effort to inventory second-by-second data generated outside of EPA and process it for inclusion in MOVES analyses is documented in Mobile Source Observation Data (MSOD) Database Update, Interim Report (PDF) (60 pp, 684K, EPA420-R-02-033, October 31, 2002) Produced by Eastern Research Group, Inc.
• An onboard emission analysis "shootout" was conducted by EPA to evaluate potential methods for analyzing onboard emission data in MOVES. A pilot dataset of onboard data was provided to three contractors: University of California at Riverside, North Carolina State University, and ENVIRON Corporation. The contractors developed models with these data which were used to predict a set of independent operation on an additional set of vehicles. EPA also participated in the shootout. Methods and results for all approaches are summarized in (EPA420-R-02-033, October 31, 2002) EPA's Onboard Analysis Shootout: Overview and Results (PDF) (66 pp, 780K, EPA420-R-02-026, October 2002)  Individual contractor reports are posted below, including the test program report from Sensors, Inc.

General Background

• EPA's New Generation Mobile Source Emissions Model: Initial Proposal and Issues (PDF) (52 pp, 200K, EPA420-R-01-007, April 2001) This report outlines an initial approach for the model, for the purpose of eliciting comments from stakeholders and model users. The comment period ended July 1, 2001.
• The recommendations contained in the National Research Council's report "Modeling Mobile Source Emissions" (May 2000) are a major driver for the New Generation Model effort. To view this report on-line, go to http://www.nap.edu/books/0309070880/html/
