Easy Python tools for EPA MOVES project-level analysis

Project Description

movespy simplifies interaction with MOVES and traffic microsimulation for project-level analysis.

Dependencies

movespy depends on:

Installation

Download the installer and run it.

Also edit the movespy_settings.py file:

  • moves_dir: a string that is the path to you MOVES installation directory
  • moves_db: a string that is the name of your MOVES database (assumed to be local)

Usage

The following code executes a complete MOVES run and calculates the total CO emissions:

>>> links = {1: {'grade': -1.2,
...              'length': 0.25,
...              'road_type': 5,
...              'source_distr': {21: 1.0},
...              'speed': 34,
...              'volume': 400}}

>>> activity =  {'age_distr': {21: {5: 1.0}},
...              'county': 50027,
...              'day_type': 5,
...              'hour': 16,
...              'month': 6,
...              'year': 2015,
...              'links': links}

>>> options = {'detail': 'average'}

>>> import movespy.moves
>>> moves = movespy.moves.Moves(activity, options)
>>> emissions_out = moves.run()
running MOVES ...
>>> total_CO = sum([row['quantity'] for row in emissions_out if row['pollutant'] == 2])
>>> print total_CO
102.772

This code calculates VSP and operating mode for a vehicle trajectory dataset:

>>> veh = [1,1,1,1,2,2,2,3,3,3,3,3]
>>> speed = [3.,6.,1.,3.,8.,5.,6.,3.,9.,1.,3.,9.]
>>> grade = [1.,2.,-3.,1.,2.,1.,3.,1.,-2.,3.,-4.,-2.]
>>> mass, mass_factor, alpha, beta, gamma = 2., 1.5, 0.16, 0.0020, 0.00049

>>> import movespy.trajectory

>>> vsp, opmode = movespy.trajectory.getVSPOpMode(veh, speed, grade, mass,
... mass_factor, alpha, beta, gamma)
>>> print vsp[:3]
[ 0.1462389   5.79980985 -1.45965811]
>>> print opmode[:3]
[12 13  0]
