FIXED-TIME TRAFFIC CONTROL FOR SIGNALIZED DIAMOND INTERCHANGE COMPLEXES

A comparison was made between a fixed-time 'before' operating condition and an 'after' condition using the Design Manual procedure. The 'before' condition was developed using a time-space diagram and other traffic engineering techniques. Stop per vehicle, delay per vehicle, and speed were the measures of effectiveness used in the comparison. Time-lapse photography was used to collect the data. A statistical analysis was used to determine the significant values. A savings associated with these significant values was then determined.
