Roadway Optimizer Settings

The Roadway Optimizer Settings dialog allows you to specify the allowable precision and spacing ranges for Roadway Optimizer as well as some display and printing options. These settings are applied towards all new job files.

General

Symbol Scaling Factor - The default value is one; the symbol will be displayed at the same scale as the rest of the layout. You may increase the size of the luminaire symbol to make it easier to see by entering a different value in this field (whole numbers only).

Symbol Line Weight Factor - Changing this value will make the lines used in the luminaire symbol thicker or thinner.

Photometric Web Scaling Factor - This value will increase or decrease the size of the photometric web for each luminaire (visible only by clicking on the Photometric Web button on the top menu bar).

Include Surfaces In Display - This is checked by default, causing a gray colored area to be displayed within one luminaire cycle in the graphics display area, representing the pavement surface. Removing the checkmark removes the gray colored area.

 

Comparison

This section allows you to choose the information to display on the Comparison tab. All are selected by default. Click in the check box to add or remove a checkmark.

 

Calculation Metrics

In this section, you may select which metrics will be included on the Comparison tab and in printed output. All are selected by default, but only those that are calculated (as determined by the selected roadway standard) will be included. Click in the check box to select or deselect a metric.

You may also set the number of displayed decimal places for results. Note: These apply to the basic metrics only (e.g., Max and Min), not to averages or ratios. The displayed decimal places for averages and ratios are controlled in the System Settings dialog (AGi32's main tool bar), Units tab.

To change the color of the metric in the graphic display, click in the Color box for that metric (initially black). Select a color and click OK to return to the Settings dialog.

 

Optimizer

Precision - Average (Avg) - This setting allows you to set the acceptable precision range (+/- percent) for the calculated average value of luminance and illuminance when calculating spacing to achieve desired values. Calculations stop once the value falls within the acceptable range. Ranges are 5% to 50% above the desired value, and 0% to 50% below the desired value. For example: If the calculated average value is to be ≥ to the desired value, set the (-) range to 0%.

Precision - Minimum (Min) - This setting allows you to set the acceptable precision range (+/- percent) for the calculated minimum value of luminance and illuminance when calculating spacing to achieve desired values. Calculations stop once the value falls within the acceptable range. Ranges are 5% to 50% above the desired value, and 0% to 50% below the desired value. For example: If the calculated minimum value is to be ≥ to the desired value, set the (-) range to 0%.

Precision - Ratio- This setting allows you to set the acceptable precision range (+/- percent) for the calculated Avg/Min, Max/Min, Min/Avg, Min/Max, and Max Lv Ratio when calculating spacing to achieve desired values. Calculations stop once the value falls within the acceptable range. Ranges are 0% to 5% above the desired value, and 0 to 5% below the desired value. The default precision range for any of these ratios is +0% to -3%; for a 0.3 Value this range corresponds to 0.3 to 0.291.

Maximum Allowable Spacing - This setting defines the maximum allowable spacing in units of mounting height up to 30. Calculations stop when the spacing exceeds this value. For example: Maximum Allowable Spacing = 10 and Mounting Height =30 ft. The actual maximum allowable spacing = 10 x 30 = 300 ft.

Minimum Allowable Spacing - This setting defines the minimum allowable spacing in units of mounting height down to 1. Calculations stop when the spacing falls below this value. For example: Minimum Allowable Spacing = 1 and Mounting Height =30 ft. The actual minimum allowable spacing = 1 x 30 = 30 ft.

Maximum Number of Iterations - This setting determines the maximum number of iterations (up to 30) that Roadway Optimizer will perform in order to achieve each desired criteria. Calculations will stop once this value is reached. In this case, the last iteration results will be displayed.

Round Spacing to Nearest - This setting specifies the rounding to apply to the calculated spacing value. For example: A rounding of one results in possible spacing values of 130,131,132,etc. A rounding value of 5 will yield spacing values of 130, 135, 140, etc. A rounding value of 0.25 will yield spacing values of 130.25, 130.5,130.75, etc. The units will be feet or meters, depending on the units selected in Model Mode.
