SafetyQuestion 697 of 700
A temporary traffic control (TTC) zone is typically divided into four areas. Which sequence correctly lists them in the order a driver encounters them?
a.Advance warning area, transition (taper) area, activity area (with buffer space), and termination area
b.Activity area, advance warning area, termination area, transition area
c.Termination area, activity area, transition area, advance warning area
d.Buffer area, activity area, advance warning area, transition area
Explanation
Correct: a driver first meets the advance warning area (signs), then the transition area where the taper moves traffic over, then the activity area where work occurs (including the buffer space that separates traffic from workers), and finally the termination area returning traffic to normal. The other sequences scramble this order and would place work or termination before drivers are warned, which is unsafe and incorrect.

- On a 40 mph roadway you must shift traffic laterally by 10 feet with a merging taper. For speeds of 40 mph or less the taper length formula is L = W x S squared / 60 (L in feet, W = offset in feet, S = speed in mph). What is the MINIMUM taper length?
- In a taper on a 45 mph roadway, a common rule of thumb for the maximum spacing between channelizing devices (cones) in the taper is that the spacing in feet should be about equal to the speed in mph. Roughly what maximum cone spacing does that give?
