I'm curious as to the technical details. I can't imagine why investigators couldn't get access to the raw Sun Pass database, which records tag id, toll booth, and a timestamp, if it works anything like my EZ-Pass system. From that, it's trivial to match up enter/exit records and divide the distance by the time to come up with an average speed. The article says they got the data from 12 police departments. I wonder what kind of records they obtained.
- ajtaylor 13y agoI wondered the same thing. Perhaps the distance between toll booths is what they measured in the 2500 miles driven? It seems like you should be able to get the data from OSM as well, with a lot less time required!
- treerock 13y agoJust guessing here, but I'd imaging they they would have to request the police car transponder details from the police departments, so they could filter police from other drivers.
