Tracking and mapping

Upbeat article in USA Today on how aggregated location data from cell phones could be used inform solutions to urban congestion problems. Also examples of how phones could receive location-based information to help in everyday tasks such as
- finding parking spaces (or avoid full car parks)
- hailing taxis
- finding new meeting location, when meeting venue is changed at last minute.

On a more emotive note Christian Nold has created aggregated mappings of people's galvanic skin response (GSR) in different locations (GSR is an easily measurable indicator of people's emotional arousal, but doesn't explain the nature of the arousal). Some maps are easier to interpret than others, like the peak in emotional arousal at a busy road junction in Greenwich. (Via Mindhacks)
