Dynamic and responsive transportation systems are a core pillar of equitable and sustainable communities. Achieving such systems requires comprehensive mobility data, or data that reports the movement of individuals and vehicles. Such data enable planners and policymakers to make informed decisions and enable researchers to model the effects of various transportation solutions. However, collecting mobility data also raises concerns about privacy and proprietary interests. We argue that a middle-ground approach, in which data are shared in specific contexts and managed by a trusted third party, can capture the benefits of data sharing while minimizing risks. This brief provides an overview of the top needs and challenges surrounding mobility data sharing and presents relevant policy strategies.
