Turning movement count
A turning movement count or TMC is a type of traffic count that counts the flows of people and vehicles through an intersection. As with other traffic counts, they may be conducted on either a temporary or permanent basis and may use a variety of different technologies such as recorded video processed with image recognition algorithms or manual field collection assisted by tools like turning movement counters.
Classifications
TMCs may classify different users of the intersection and provide separate counts for each. For example a TMC could provide separate movement counts for trucks, buses, other motor vehicles, cyclists, and pedestrians.Pedestrians, who don't use turning lanes in the roadway, may be counted differently such as when they cross the street in marked or unmarked crossings.
