The Flagstaff Snow Play app is a comprehensive source for winter recreation activities in Northern Arizona, with its own custom traffic map. There are thousands of motorists traveling our roads every day with mobile devices in tow. Traffic flow data is based on real-time movement of active Maps users, other proprietary sources, and 3rd party traffic data providers. The Flagstaff Snow Play map shows the main traffic veins through Flagstaff and indicates where traffic flow is good, and where it is congested. This enables travelers to plan alternate routes and navigate around congested areas.
