MOT Work Zone Planning & Design Principles 5

Question 1

During the planning phase of a work zone, a road safety audit (RSA) is best described as:

Accepted Answer

A formal examination of a proposed work zone plan to identify safety issues before implementation

Answer

A Road Safety Audit is a formal, proactive review of the TTC plan by an independent team to identify and correct safety deficiencies before the work zone opens to traffic.

Question 2

On an Interstate highway work zone, what is the required minimum clearance between the edge of the nearest open travel lane and stationary workers or equipment?

Accepted Answer

It varies based on traffic volume and speed

Answer

The required clearance between open travel lanes and stationary workers/equipment varies and is specified in the project's TTC plan based on traffic speed, volume, and site conditions.

Question 3

Which of the following is a key reason for conducting a traffic study before designing a work zone on a heavily traveled urban arterial?

Accepted Answer

To understand peak traffic volumes and identify the least disruptive times for lane closures

Answer

A pre-construction traffic study reveals peak periods and volume patterns, enabling planners to schedule lane closures during off-peak times to minimize congestion and safety risks.

Question 4

What is the purpose of the 'work space' within the activity area of a work zone?

Accepted Answer

To contain all workers, equipment, and materials needed for the construction activity

Answer

The work space is the portion of the activity area exclusively reserved for construction workers, equipment, and materials, kept physically separated from moving traffic.

Question 5

When a work zone requires contraflow operations (reversing the normal direction of travel in a lane), what is a critical design element that must be included?

Accepted Answer

Positive separation barriers between opposing traffic streams

Answer

Contraflow operations require positive separation (such as temporary concrete barriers or water-filled barriers) between opposing traffic flows to prevent head-on collisions.
