MOVES5

EPA's MOtor Vehicle Emission Simulator (MOVES) is a state-of-the-science emission modeling system that estimates emissions for mobile sources at the national, county, and project level for criteria air pollutants, greenhouse gases, and air toxics, available under EPA's Open Source Software policy.

MOVES5 (available at https://github.com/USEPA/EPA_MOVES_Model and https://www.epa.gov/moves/latest-version-motor-vehicle-emission-simulator-moves) is the latest version of MOVES available for regulatory purposes. For more information, see MOVES5 Policy Guidance: Use of MOVES for State Implementation Plan Development, Transportation Conformity, General Conformity, and Other Purposes (EPA-420-B-24-038).

For additional information on MOVES, visit EPA's MOVES website. A standard installer for MOVES is available here. Or, to compile and MOVES from source, follow the instructions below.

Requirements and Set Up

This repository contains all of the source code and data required to compile and run MOVES.

MOVES uses MariaDB, Java, and Go. To run MOVES from the source code (i.e., without running the installer), you will need the following:

MariaDB (version 10.11 is recommended)
Java JDK (version 17 is recommended)
Go (version 1.13 or later)

To get set up:

Clone or download this repository.
Make sure MariaDB, Java, and Go are all installed and available on your system path (i.e., make sure the \bin folders for each of these are in your PATH environment variable). You can test this by running each of the following lines in a command prompt:
- mysql.exe --version
- java.exe -version
- go.exe version
MOVES has some specific MariaDB configuration requirements. Locate the MariaDB configuration file (on Windows, this is my.ini located in your data directory; see #4 of Quick Start Guide to Accessing MariaDB Data for help on finding your data directory), and ensure the following lines are saved in the file:
```
[mysqld]
default-storage-engine=MyISAM
secure-file-priv=''
sql_mode=STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
lower_case_table_names=1
character-set-server=utf8mb4
collation-server=utf8mb4_unicode_ci
init-connect='SET NAMES utf8mb4'
```
Restart the MariaDB service after modifying this file.
If MariaDB is running on a non-default port (i.e., any port other than 3306), create a file called MySQL.txt in the root MOVES directory, and save the port number to this text file. This file should contain no whitespace, just the port number.
Uncomment line 2 of setenv.bat and comment out line 3 to set the JDK and JRE paths to match your environment (i.e., remove REM from the beginning of line 2 and add it to the beginning of line 3). Then, set JAVA_HOME to your JDK path on line 6.
Unzip the default database dumpfile from the .zip file in the \database\Setup directory to the same directory.
Edit \database\Setup\SetupDatabase.bat to use the MariaDB root user's password, and then run it. This batch file creates the MOVES database user by running \database\Setup\CreateMOVESUser.sql, and then installs the default database by running the dumpfile you extracted in the previous step.

Note: if MariaDB is running on a different port, you will need to edit SetupDatabase.bat to add the command-line flag --port=XXXX, where XXXX is the port number.
Open a command prompt, navigate to your MOVES source code directory, and run the following commands to compile MOVES and launch the GUI:
```
setenv
ant crungui
```
For additional information about compiling MOVES, see CommandLineMOVES.md.
Hereafter to run MOVES, simply navigate to the MOVES directory and run:
```
MOVESMain.bat
```
