Figure 14 Work Zone Decision-Making Engine Process

On top are the three work zone categories: planning, pe/design, and construction. Below these labels are three decision-making engines for each category. The planning engine is the smallest. The pe/design engine is the second biggest. The construction engine is the largest. Each engine has the circles of different finality indicating how many decisions have been made. Below the engines is an arrow indicating the decision evolution pointing from left to right. Below the arrow is a rectangular box with a diagonal line going from the bottom left corner to the upper right corner. The upper section are modeling opportunities. The bottom section are data requirements.
