The Calculation Points – Roadway command is available from within the main Model Mode environment of AGi32. Similar to the Roadway Optimizer, it performs calculations based on any of the supported international standards. However, in the model environment, the command can be used to place composite roadway calculations in position on top of 2-dimensional CAD created backgrounds considering all luminaires placed within the environment. This provides designers the flexibility to consider any luminaire type and position in the various roadway specific calculations. For example: luminaires can be considered not only along the roadway, but from intersecting roadways, adjacent site lighting, pedestrian lighting or any off-roadway source. Roadway specific calculation point grids can also be stretched across more than one pole cycle to encompass any distance. AGi32 makes every attempt to adhere to the various international standards when grid size exceeds that specified in the standard.


Steps to use AGi32’s Calculation Points – Roadway command

Each step references Figure 1 below

  1. Enter a Label and Description for this calculation
  2. Select the Roadway Standard to be used as the calculation basis
  3. Enter the number of lanes in the direction of travel
  4. Select the R-Table to describe the pavement surface characteristics
  5. Standard calculation metrics for the selected standard are shown on the left. They can be deselected. Specifics associated with each metric will appear in the area on the right
  6. Various aesthetic settings can be adjusted if necessary

By clicking OK in the dialog, control is transferred back to the graphics cursor in the Model view. Locate the grid using three points as shown below.

  • Point number one (pt1) is on the curb line at the beginning of the analysis zone.
  • Point number two (pt2) is on the same curb line at the end of the analysis zone.
  • Point number three (pt3) is directly across the roadway from point 2 defining the width of the road in the direction of travel.

The end result can be a series of calculation areas within the project, each in position to analyze the specifics at that location. All luminaires in the project are considered in the final calculation.
