re: Traffic monitoring system uses Bluetooth sensors over ZigBee

A great idea in theory, but it presumes that everyone who has a bluetooth interface on their phone or car is using it. I tend to only turn mine on when I need to use it as opposed to having it on 24/7.

I agree. The system is either not fully explained, or there are some serious issues to be worked through. However, there definitely needs to be major improvement in the measurement of traffic flows, both vehicular and pedestrian in most cities, and in the control of that traffic flow, and the more systems and ideas we have to that end will lead to doing those things better.

Given size of the bluetooth radio coverage, there will be a large quantity of bluetooth receivers needed to be installed. The big city which has more than 3 lanes will be a challenge as well. In downtown area, how does the system filter out pedestrians?

Will look forward to the reports from those two Smart Cities Events. If a person carries multiple blue-tooth enabled devices in a car...won't cause the system to detect misleading info about the traffic? May be I don't understand this system yet.
