A traffic signal control is being designed for a four-leg intersection on a divided highway with the characteristics shown in the table below. Determine an appropriate length of the yellow interval for each approach and how you will provide it.
N-S Approaches E-W Approaches
Intersection Width, (ft) 84 96
design Speed, mi/h 45 50
Grade 2.5 % 3%
Assume the average vehicle length L is 20 ft, and the perception-reaction time is 1.5 Sec.
