Traffic operations studies are undertaken to determine the characteristics of transportation system users, to monitor system operation, to identify problem areas, and to assist in developing appropriate remedial actions. ITE’s Manual of Transportation Engineering Studies provides in-depth discussion of 18 different types of transportation engineering studies. This module focuses on statistical analysis and principle types of traffic operations studies, including volume, speed, travel time and delay, parking, pedestrian studies, traffic impact studies, and urban and regional planning studies.
