Portland smart city mobility tracking 

The US city of Portland, Oregon, has decided not to go ahead with a plan to track mobility patterns of how people move throughout the urban area. The plan had been to use mobile tracking data to inform decision-making about bike lane, road repair and bus service planning. 

According to reports, Portland Metro decided to pull out largely because as a series of disputes with Google's Sidewalk Labs spin-off Replica over data quality, transparency, and privacy. Conversely, Replica says it was unwilling to share data to the level of detail requested by the city.

Last year, a Sidewalks Lab project to build a smart city in a disused waterfront area of Toronto also fell apart. An independent review panel had criticised the plan as 'tech for tech's sake', with some of the proposed elements 'irrelevant or unnecessary'.
