Master Planning & Smart Cities
Peña Station NEXT
The proposed sign luminance thresholds for Peña Station NEXT were developed with consideration for clarity and legibility of signs, while controlling the visual impacts of glare for drivers and pedestrians, and light trespass for residents.
Using a range of objective and subjective measures such as high dynamic range imagery analysis and community surveying, Clanton & Associates determined max luminance metrics for common visual conditions, including nighttime, overcast, and sunny conditions as well as the angle of view and activity of observers. This sign code overlay also created new standards for electronic signage to define acceptable frequency of changing ads, fade rate between ads, and full motion video.
It was found that in order to provide for visual clarity and legibility during the day, the sign luminance must be controlled with local light sensors to automatically brighten and dim the sign to adapt to the changing ambient daylight conditions from bright clear sky conditions to overcast sky conditions. Recommendations were also made specifying that maximum sign luminance should be bright enough to be clearly legible against background sky luminance, without becoming too bright or glaring.
Clanton & Associates has developed street and pedestrian lighting master plans, lighting criteria, tours, pilot demonstrations, surveys, lighting measurements, and lighting research projects. Our extensive experience in creating street lighting master plans and guidelines for cities, assists our clients in making informed decisions regarding street lighting design to plan for the future of smart cities.
