The Traffic Control & Safety crew controls both vehicular and pedestrian traffic at Opening Ceremonies, and traffic control and safety along the route as needed. This crew will maintain safe traffic flow, manage parking lots and staging areas, and keep an eye out for participants needing guidance, and provide an open access for emergency vehicles. The volunteers on this crew must be on their feet for long periods of time, and must be able to physically navigate and transport oneself from one point to another, often at very short notice.
Route marking is part of the Traffic Control & Safety crew. This crew is responsible for marking the entire Walk route with directional signs, safety cones, and clearing the signs/cones after the walkers have passed and the route is closed.
Sweep is part of the Traffic Control & Safety crew and consists of several vehicles, each with a driver and navigator that patrol a section of the route between the Pit Stops and lends a hand to injured/disabled participants.
