This was meant to happen, via the LinkedIn OpenStreetMap group I learned about the OpenTraffic project.
Here's their introduction: "OpenTraffic is a open data project initiated by doroga.tv to create open traffic jam map of the world. We use OpenStreetMap vector graph and data feeds from various fleet management systems to calculate the traffic. Each contributor and every developer may use the traffic APIs for mapping and navigation projects and researches. […]
If you'd like to start OpenTraffic project in your area, you need to do the following steps:
- Contact us so we could install the vector OpenStreetMap data for your region
- You need to provide datafeeds from GPS-equipped vehicles so we can calculate traffic based on that data
- Enjoy! Access the traffic data by API and use it on any web or mobile map"
