Portland ponders pilot of powerful transportation data tool – UPDATED

A powerful new data collection tool has local transportation agencies salivating.

Replica by Sidewalk Labs (owned by Alphabet, the company that owns Google) bills itself as a “next-generation urban planning tool.” Using location data gleaned from cell phones and other sources, Replica creates a “synthetic population” based on aggregate U.S. Census data. The promise of this tool is that it can give planners and engineers unprecedented insights into the traffic patterns and mobility behaviors of urban residents.

From regional trends to fine-grain analysis of travel to-and-from specific destinations, this data has vast potential. But it also requires trust from a wary public fearful of privacy breaches and government/corporate overreach.

At this morning’s Portland City Council meeting, the Portland Bureau of Transportation urged Mayor Ted Wheeler and his colleagues to approve an intergovernmental agreement (PDF) between PBOT, Metro and TriMet that would enable the agencies to enter into a 12-month pilot with Sidewalk Labs. Here’s more from the official city ordinance under consideration:

“The more information we have about how, when, and why our streets being used, the better we are able to plan for and accommodate those demands and make our city work better for everyone.”
— Chloe Eudaly, city commissioner

“Sidewalk Labs is seeking metropolitan regions to pilot test Replica, a data tool developed by Sidewalk Labs, a subsidiary of Alphabet, Google’s parent company, that provides a high-fidelity, synthetic representation of how people travel during a typical week… As designed, Replica is capable of providing the City of Portland with rich data pertaining to transportation supply (the configuration of the roadway network, transit service, bicycle routes, and footpaths), transportation demand (representations of all personal travel that takes place in the region), land use (estimates of how land is used, for example, estimates of spatially-specific employment and school enrollment estimates as well as spatially and temporally-specific estimates of other activities, e.g., shop, eat, recreate), and demographics (including income, race, and household size). This data is not currently available to PBOT at the volume, depth, or frequency that the Replica tool is able to provide; and, access to this data, once validated, has the potential to greatly enhance PBOT’s ability to understand how people are moving through our transportation system as well as if and how investments in this system ultimately impact mobility and motivate transportation choices.”

PBOT Commissioner Chloe Eudaly said she’s “very excited” about the project. “The more information we have about how, when, and why our streets being used, the better we are able to plan for and accommodate those demands and make our city work better for everyone.”

Eudaly addressed the privacy issue by saying all the information (before it even reaches Sidewalk Labs) would be “de-identified.” “This is not about tracking individuals,” she assured council prior to the staff presentation.

“This tool can fundamentally change the game for us.”

The PBOT staffer who pitched the concept to City Council said the data provided by Replica would be “core to the work we do.” The idea is being sold as a way to measure whether current transportation investments are working, or whether or not future investments would result in desired outcomes. If Sidewalk Labs can meet the City’s privacy regulations, the PBOT staffer said Replica could be, “game-changing.” “Today we do it via surveys and hand-counts. It’s expensive and labor intensive,” he shared. “This tool can fundamentally change the game for us.”

The 12-month pilot would cost $457,300 (based on total population if the Portland metro area at a cost of 20 cents person), which would be split three ways by PBOT, Metro and TriMet.

It might seem like a slam-dunk decision for Council, but privacy concerns are sure to take center stage. Three members of the public testified at this morning’s hearing with strong opposition to the idea. Between now and the second reading of the ordinance where a vote could happen, Mayor Wheeler and others might look to Toronto where Sidwalks Labs is in the middle of a major debate over how their Replica tool will be used to plan an entire neighborhood.

Portland isn’t new to the big data/urban planning space. PBOT already has a contract with local firm Ride Report that offers a data dashboard showing bike counts and bike/scooter share locations. And in 2016, PBOT pitched then US DOT Secretary Anthony Foxx on their “Ubiquitous Mobility” concept that was a finalist for a major “smart city” prize (which we ultimately lost to Columbus, Ohio).

Margi Bradway, a former staffer at the Oregon Department of Transportation who brokered a deal to use GPS data from Strava, a popular cycling app, brought her love of data to PBOT when she was hired to lead their Active Transportation Division in 2014. Bradway now works at Metro where she’s deputy director of transportation planning. Metro will be the lead agency on the Replica project if and when it’s approved by Portland City Council.

Learn more about Replica here and stay tuned for its next hearing.

UPDATE, 12/13: City Council passed the ordinance yesterday. Here’s a report from OPB.

    Massive privacy concerns here. Google uses this excuse all the time, that your data is “de-identified” and not directly traceable to you, but the fact of the matter is that Google is a company that profits off of aggregating data and actions to build a comprehensive knowledge network able to make predictions about human behavior and to show you more ads. Google literally profits off of your personal information, through free services like Gmail, Search, Chrome browsing history, Android phone assistants, etc. This is a massively lucrative business and Google just can’t wait to get their hands on more public data from governments. This is all done to show you increasingly personal and invasive ads, and to gain more control over the free internet.

    Eudaly caving to Google here goes against everything she campaigned for, although is not surprising since people like her tend to play the part of representing “the people” but always caving to business interests or personal gain in the end. City governments should be saying no to Google and their invasive tactics.

    Well, Google gets a cookie for finally using the mountain ranges of aggregate data they have for public projects. That said, I do wonder about blind spots in their data. How many people are not on smart phones at all? Where this data would be most useful is how people react to ever new pattern PBOT introduces to the network.

      “De-identified mobile location data” has nothing to do with smart phones. Any 3g/4g mobile device contributes this data as a fundamental part of transiting a mobile network, whether you have an iPhone XS or a $40 burner flip-phone. It’s the same data that drives things like traffic overlays in Google Maps, which comes directly from Verizon/AT&T/etc towers. The only way to opt-out is to turn your phone off.

        Google has to have access to that data first to collect it. Last I checked, Google is not Verizon, AT&T, et al. They do have the Google Fi network for high-end Android phones, but I’m not on it.

          They buy it. “telco data as a service” is a multi-billion-dollar industry, notwithstanding Ron Wyden’s recent efforts to clamp down on some of the shadiest actors.

        The “de-identified mobile location data” means they’ve removed any identifiable, traceable information to you. Again, unless Google is buying that info from the wireless telcos (they may be), they don’t have access to data like this without apps installed on smartphones which are using location services.

          “de-identified mobile location data” is specific jargon for exactly that – mobile networks selling cell tower location data.

    Google is already tracking you. Those apps running in the background on your phone give them everything they need. This simply gives the city access to something Google already has.

      If you’re using iOS and you’ve changed your default search engine, don’t use YouTube, and don’t use Google Maps or Waze — then they’re not collecting any data from your phone. It is possible to go dark on Google with a smart phone. If you’re using Android, you’re probably fudged — I bet there’s ubernerds out there that go dark that really want to, but it’s likely exceedingly convoluted.

      But yeah, most everyone that cries “privacy!” has probably already given away their privacy to any number of data collectors — Amazon, Google, Facebook, Twitter. That ship sailed long ago. And until our Congress is willing to create regulations like the EU’s GDPR, they’re going to keep owning our personal data. As long as that aggregate data is out there, I’d rather have it used to improve civil design than to sell me more doodads I don’t need.

        We as consumers, as voters, and as individuals haven’t valued privacy enough to retain it. We traded privacy for convenience, speed, and other features. That was and is our individual day- -to-day choice. If you’re not using non-mainstream privacy-specific products for email, messaging, phone calls, and web browsing, then you have given up your privacy voluntarily.

        Even with concerted, extensive effort, it is very, very difficult to retain privacy. But that doesn’t necessarily mean we should throw our hands and the air and give up.

          Agreed. And at the same time, as long as the data is there, can it not be used for the public good by public agencies (that cannot reverse engineer the data to track you down or other nefarious practices) as useful model data for planning? Because this is exactly what we’re talking about.

    I’m more concerned about accuracy than privacy. Even Ride Report, which should be prejudiced in favor of bike rides, guesses I’m driving to work much of the time. (I’ve driven to work a total of once in the last five years. Google, start seeing bicycles.

      Ditto on where my concerns lie. I say I correct about half of my entries on Ride myself; most recently it thought a bus ride was a train ride for some reason. I also worry about who and what isn’t represented by data that Google isn’t capturing in that mega set. You can only analyze that which you capture, not that which you fail to capture.

    As long as they match drinking establishment data with auto driving data in real time and make that available to the police, I’m thinking it will be worth it.
