# MATSim Runner Script
|
|
## Requirements
|
|
- [x] [JDK 17](https://www.oracle.com/java/technologies/downloads/#java17)
|
|
- [x] Python 3
|
|
|
|
## Goal
|
|
Estimate city pollution coming from people driving in vehicles.
|
|
|
|
## Setup
|
|
Make sure to have JDK 17 installed and clone this repository.
|
|
|
|
## Usage
|
|
The file `main.py` is essentially a replica from MEB workflow. It constructs a city and then allows the user to apply characteristics to that given city.
|
|
|
|
The difference is in the implementation of MatSimEngine. This engine should create the following files:
|
|
- facilities.xml
|
|
- network.xml
|
|
- population.xml
|
|
- config.xml
|
|
|
|
Facilities and network are quite simple as the facilities file can be built from our city object and the network file can be built using a matsim utility along with OpenStreetMaps data. The population file must be generated via other ways and the config file can be generated once the first 3 files are created.
|
|
|
|
Additionally, it may be interesting to include public transport in the simulation. This is a potentially simple task. Montreal offers the GTFS files for its public transport for free and the project [PT2MATSim](https://github.com/matsim-org/pt2matsim) allows you to create the MatSim xml files from the initial GTFS files.

|
|
## Visualization
|
|
|
|
Given we want to be able to visualize the results similar to the way the Munich scenario did it: https://www.matsim.org/gallery/munich.
|
|
|
|
The repository also has the code to visualize these results. It's a very basic implementation, but it basically uses matplotlib and nx to plot the network and how much traffic exists on a given link at a given time.
