MOT Work Zone Planning & Design Principles 4

Question 1

Under MUTCD guidelines, advance warning signs in a work zone are typically colored:

Accepted Answer

Orange and black

Answer

Temporary traffic control signs in work zones use orange backgrounds with black lettering/symbols, distinguishing them from permanent highway signs.

Question 2

When a work zone project spans several months, what type of plan is typically developed to address different phases of construction?

Accepted Answer

A phased TTC plan with different configurations for each construction stage

Answer

Long-duration projects require phased TTC plans that show separate traffic control configurations for each distinct stage of construction as conditions change.

Question 3

What is the minimum recommended spacing between channelizing devices (e.g., cones) in a taper on a 55 mph highway?

Accepted Answer

55 feet

Answer

Device spacing in tapers is generally equal to the posted speed limit in feet (e.g., 55 feet at 55 mph), ensuring adequate visual guidance for drivers.

Question 4

In a work zone traffic control plan, a 'pedestrian channelizing device' is used to:

Accepted Answer

Provide a safe, defined pathway for pedestrians through or around the work zone

Answer

Pedestrian channelizing devices create a physically separated, accessible path for pedestrians, including those with disabilities, through or around the active work area.

Question 5

Which type of work zone is defined as lasting more than 3 days in the same location?

Accepted Answer

Long-term stationary

Answer

The MUTCD classifies a work zone as long-term stationary when it remains in essentially the same location for more than 3 days.
