Data
Three kinds of data are generally needed for traffic analysis. Demand or volume information specifies the turning movement flows (usually in vehicles per hour) at each intersection approach. Intersection geometry includes the number and configuration of lanes at an intersection and along an arterial. Control conditions include information about the traffic signal system, including signal timing and phasing data. For this particular case study, pedestrian, bicycle, transit, and intersection spacing and queuing data are also very important.
