Sumo Code Snippets

1. Introduction

This repository contains code snippets that I have developed with the intention of automating some of the processes that I have come across when developing SUMO simulation models.

2. Usage

You are most welcome to use thesee code snippets for your projects. If you need any assistance, please write to me ([email protected]). Also let me know if you think the codes/functions can be further improved.

3. Code Snippets

3.1 Matching traffic counts to the random routes generated by SUMO

This scripts is useful if you have actual counts at few edges of your network and you want to make a .rou.xml file that matches those counts. Here, the script routeSampler.py has been used.

3.2. Generate Bus Flows with Random Stop Times

Using static stop times at a bus stop are not realistic to use in a simulation. Here, I have tried to generate random stop times at a bus stop based on different types of busses. For example, in Sri Lanka, there are 1) Short Distance Busses, 2) Long Distance Busses, and 3) Other Busses (office transport etc.)

3.3. Adding Vehicle Type to a Route File

The idea of this script is to add vehicle type to a rou.xml as the route file doesn't have vehicle type in general (there is a method to do this if you have different percentages of modes - via an .add.xml file).

In this script, the .rou.xml file is first converted in to a .csv file and then based on the time stamp (given that you have aggregated counts for 5 mins intervals + the vehicle type) a 'vehicle type' is allocated (in a random fashion) to the .csv file and convert the .csv back to an SUMO compaticle .rou.xml file.
