CIE Workshop on a New Vision of Visibility for Roadway Lighting

Why do we light our roads? All road users should be able to see objects on the road and should be visible to each other. Good visibility conditions are assumed for this. Different methods have been developed for the description of visibility conditions, unfortunately these methods have been never used in practical lighting design processes, often due to the omission of some variables relevant to the models, for example: measurement methods for the road surface reflection, optimization tools for the reflector or lens design of luminaires, consideration for luminaries with adjustable light distribution, and lack of imaging luminance measurement systems.

Now however, there are new ways of lighting with LED based luminaires and imaging luminance measurement systems are available, given these this workshop will analyse the potential of the different visibility concepts. In addition, the area where scientific creativeness overlaps the uptake of new technologies both in pragmatic and economic ways will be discussed.
