[pgrouting-dev] Travel Time Analysis

Hi,

While searching for ways to generate good time dependent data, I came across Travel Time Analysis[1]
The Travel Time Analysis project aims to provide more accurate travel time estimation based on GPS traces. It takes as input OSM map and GPX files and provides tools to generate travel time models. One drawback is: All utilities require .NET runtime or MONO runtime installed on the computer.

Anyways, I am not sure from where we can obtain GPX files and corresponding map data for free. Any sources?

Also, their results are in form:

<models-db>
   <model node-from="1" node-to="2" way="100" freeflow="58.8" avg-delay="11.9">
     <traffic-delay from="00:00:00" to="04:45:00" day="Monday" delay="0.7" />

     <traffic-delay from="07:00:00" to="14:00:00" day="Monday" delay="14.3" />
     <traffic-delay from="14:00:00" to="16:00:00" day="Monday" delay="33.1" />

     <traffic-delay from="16:00:00" to="19:30:00" day="Monday" delay="19.5" />
   </model>
 </models-db>

So, a converter would be needed to convert the data format into pgRouting data format. Any such tools already available?

You can download OSM raw data, if it was uploaded by the users.

But I don’t know it’s really useful or not.
