84、A crash analysis reveals that a rural intersection has a crash rate of 80 crashes per 100 million vehicle miles.
The segment is 2.5 miles long, with an AADT of 10,000 vehicles per day over 3 years. How many crashes occurred?

85、The MUTCD requires that a “STOP HERE ON RED” sign be used when the stop line is offset from the intersection by more than:

86、For a signalized intersection, the ITE procedure recommends a yellow change interval based on a perception- reaction time of 1 second and a deceleration rate of 10 ft/s². For a 45 mph approach with a 60-foot intersection width, what is the minimum yellow change interval?

87、An intersection is STOP-controlled on the minor approach. The design speed of the major road is 50 mph.
