Turning Moving Counts
Description
Studies counting the numbers of vehicles making turns. Data goes back to 2003. Can use the traffic research tool to investigate certain areas by using the research rectangle on a specific location.
Turning movement counts are done by visually counting the vehicle passages through an intersection. By documenting the direction of each vehicles approach and departure from the intersection, the traffic demand on each lane of the roadway can be ascertained. This helps to determine if improvements to the intersection are needed.
Data is collected by different companies and can include pedestrian, bike, heavy vehicle and other counts as well.
