Figure 9 Work Zone Data Spectrum

There are three sections representing Planning, PE/Design, and Construction. A long triangle traverses these three sections from low precision to high precision. The planning section uses Demand Templates and Archived Data. The PE/Design section uses Field Traffic Count Data Collection. The Construction section uses Field Observations and Validation. Below the triangle and words is a bar indicating rough estimation on the left and detailed data on the right.
