In April, a team of representatives from Sidewalk Labs — a subsidiary of Alphabet, which is also Google’s parent company — visited Columbus, Ohio, to pitch city officials on a sprawling, ambitious plan to overhaul the city’s transportation infrastructure.

Sidewalk proposed managing and expanding the city’s transportation data on transit routes, passengers, parking spaces, cars, and more. In the process, Sidewalk promised to give the city “new superpowers” and make it more accessible.

By mid-year, Sidewalk Labs had pitched at least six other tech-hungry cities — San Francisco, Austin, Pittsburgh, Denver, Kansas City, and Portland — on the same bold proposal.

In Columbus, the company’s representatives said, two systems called Flow and Link could “pinpoint the causes of congestion,” reduce the “emissions and distracted driving that results from circling for parking,” “encourage ride-sharing,” and provide “ultra-fast gigabit WiFi.” That could be a significant improvement in a city where an estimated 82% of commuters drive to work. And though Sidewalk’s presentation does not name the final cost of the systems — it’d depend on a range of factors — it claims that the new approach could ultimately return a profit to Columbus.

But outsourcing these traditionally municipal concerns to a private company — and a high-profile technological innovator, at that — would be a stark change that could have implications well beyond central Ohio.
