Hardware-Based Commute-Map Gadget
coreymetrics writes "Anyone have one of these things? While it's no substitute for an improved mass-transit solution in the Puget Sound area, TrafficGauge's new gadget sure looks like it beats any PDA or cell phone auto traffic map I've used. It uses the same data that powers the Washington State DOT's indispensable website. Now why can't auto makers put this kind of thing in a dash instead of mostly worthless GPS navigation and DVD units?"
California's Department of Transportation is working on a similar system and I am working on the backend to a web interface similar to WSDOT's.
If there are any users of similar systems for planning travel routes/times on slashdot, what features did you find valuable, superfluous, or altogether lacking?
Is it valuable to have historic data? If so, how far back? Archived hourly analysis of traffic volumes, average time of travel on predefined routes? As a user, would you be interested in data beyond delays and congestion. Site specific information giving visibility, weather, etc?
Thank you for any responses!
