Development and Preliminary Testing of an Automatic Turning Movements Identification System

It is important for many applications, such as intersection delay estimation and adaptive signal control, to obtain vehicle turning movement information at signalized intersections. However, vehicle turning movement information is very time consuming to obtain and usually the data can only be counted manually. Previous efforts were focused on solving the problem using an O-D matrix but the result is not accurate and reliable. Limitations with the existing methods to handle shared-lane situations have prevented them from being used for many intersections. Motivated by the need to identify vehicle turning movements for many real time applications without being constrained by the intersection configuration, the University of Akron’s transportation research group has developed an Automatic Turning Movement Identification System (ATMIS) and tested it through lab and field evaluation. The results from those experiments are very encouraging with small errors compared with the ground truth. This project has demonstrated the great potential of ATMIS to be used for other applications after further testing and enhancement.
