Our platform models travel behavior over time to show how people across the country live, move, and work. This data is used by planners, scientists, analysts, and policymakers who are working to make our cities more sustainable, equitable, and resilient. We contextualize hard choices so that our clients understand the trade-offs surrounding their decisions. Whether for a city planner increasing public transit to underserved neighborhoods or for a grocery chain evaluating where to open a new location, Replica enables cities and businesses to make more informed, people-centered decisions.
