Active Tags: RFID for LBS

Report here shows where RFID might be headed: active tags. Seems like with a wireless grid and active tags, geolocation without GPS should be possible – and at a much lower cost.

Houston has contracted to have 600 square miles of WiFi. This should make it even easier to expand congestion based pricing beyond the toll roads.

What’s this got to do with GIS programming ?

Coming up with an algorithm that updates cost based on congestion levels could be interesting. Assuming pricing is based on time of day, writing a path finding routine could also become more complex.

Seems like taxi services could change too, perhaps allowing trips to be purchased through an eBay-like auction. I guess the unions would not allow this though. That’s too bad, if taxis were cheaper perhaps more people would choose not to own a car.
