Roadway Calculator

The Roadway Calculator evaluates selected intensity distributions in selected roadway scenarios. It calculates roadway lighting criteria such as luminance, illuminance, uniformity, and glare-related values according to EN 13201-style valuation fields configured in the scenario.

Scenario Selection

Use the scenario list to select the preview scenario and check one or more scenarios for calculation. Checked scenarios are recalculated against the currently selected intensity distributions.

Calculation Mode

• Luminaire Flux Mode: calculates with each luminaire's current luminous flux.
• Minimum Luminous Flux Mode: scales flux to the minimum value needed to meet average luminance or illuminance requirements, then reports whether all criteria pass.
• Lamp Luminous Flux Mode: uses the entered lamp luminous flux and applies the luminaire light output ratio.
• Set Luminous Flux Mode: directly sets the luminaire flux to the entered lumen value.

The lumen input is enabled only for the two set-flux modes.

Results

The results table groups calculations by scenario and intensity distribution. Each criterion displays the required value, actual value, and pass/fail state. In minimum-flux mode, the table also shows the required luminous flux.
