PeMS utils

This repo contains some scripts I used during my PhD at Università degli Studi di Firenze.

The dependencies are:

  • scikits-timeseries
  • python2-scipy
  • svmlight
  • python2-numpy
  • python2-yaml
  • python2-matplotlib

The folder can be of some interest for other is scripts/ and contains some python command line scripts to download and preprocess traffic data from

Those scripts are building blocks for some more complex pipeline, so loops on more stations periods are demanded on a higher level tool, as GNU make or plow.

To download the PeMS data you'll need a valid account and set <username> and <password> in the file, for example a you can download one month of data from the District7 with:

$ -d pems/d07 7 5min 2008-04

Once you have downloaded the needed dbx archives, you can run the scripts in seasonal/sh, before you have to add the scripts folder to your PATH.

For example executing:

$ sh/ five-stations.list >

will generate the script to execute the lag experiment

Examples of the usage can be found in seasonal/sh scripts. No docs, sorry.
