Replica is:  “a user-friendly modeling tool that uses anonymized mobile location data to give planning agencies a comprehensive portrait of how, when, and why people travel in urban areas.” Here is a preview of the Replica dashboard showing a section of Main Street in Kansas City. I hope the animated GIF shows up for you. The platform uses a combination of mobile location data (~5% of the population) and on-the-ground checks, typical stuff like manual traffic counts and transit boardings. The goal is to understand in real-time who is using a street, as well as how (driving? cycling?) and why (going to work?). Their introductory blog post obviously stresses the importance of personal privacy, but I am curious how they determine where people are going. I suppose if they pair journeys with destinations (and the durations at those destinations) they can make reasonable assumptions around the why. I think the benefits to all of this are clear. But does any or all of this worry you from a privacy standpoint?
