How to implement a Change Events File

by L Marquez on 2017-05-04 03:51:58

I have been unsuccessful in adding an inputChangeEventsFile (representing closures of congested roads) to my Matsim project. As per documentation, I have created a changeEvents.xml file containing:

	<link></link>

....

I have also added the required entry in the configuration file:

.....

.....

However, the new Matsim run produces the same results as the previous run without the change events file. What am I missing here? Thanks in advance for any help. Regards, Leorey

Here are the deleted parts in my question.

The changeEvents.xml file contains:

<?xml version="1.0" encoding="UTF-8"?> <networkChangeEvents xmlns="http://www.matsim.org/files/dtd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.matsim.org/files/dtd http://www.matsim.org/files/dtd/networkChangeEvents.xsd">

 <networkChangeEvent startTime="00:28:00">   <link refId="1837925"/>   <flowCapacity type="absolute" value="0"/>   <freespeed type="absolute" value="0.0"/>  </networkChangeEvent>

The entry in the config file shows:

<module name="network" >

  <param name="inputChangeEventsFile" value="./examples/evac/changeEvents.xml" />

Hi,

this is a bit tricky, but in addition to adding the file, you also need to enable the timeVariantNetwork in the same config group, i.e.:

<module name="network" >

  <param name="inputChangeEventsFile" value="./examples/evac/changeEvents.xml" />

  <param name="timeVariantNetwork" value="true" />

...

I hope that helps!
