CIE Workshop on a New Vision of Visibility for Roadway Lighting

May 24, 2018 to May 25, 2018
Berlin Germany


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 visiblity 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 ommission 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 are new  ways of lighting with LED based luminaires and imaging luminance measurement systems are avaialbe, given these this workshop will analyse the potential of the different visibility concepts. In addition, the area where scientifc creativeness overlaps the uptake of new technologies both in  pragmatic and ecconomic ways will be discussed. 
The result of the workshop should be a decision, whether the CIE needs a new technical report about this topic. If you are interested to discuss this exciting topic with leading researchers in this area then is is a workshop not to be missed.

Event Summary

o    Who should come: We invite researchers from the Industry, Government and Academia, who have been dealing with visibility or are interested in visibility for roadway lighting.

o    What you will learn at the workshop: Invited presenters will provide an overview about Characterization of Traffic Safety, on why should we use visibility, what are the basic ideas about visibility, which models are known, why this concept has not been used for the lighting design process in the past, which mesurement technique is necessary to use the concept of Visibility, and so on.

o    How you can inspire and be inspired at the workshop: Submit an abstract of up to 1000 words to describe what work you have done or are doing in this field.
We are interested in test methods for Visibility and results in laboratory or field tests. It is very important that you present results if you had no matching between your calculations and experimental data! The abstracts will be screened by the scientific committee. We want to be sure that we don't lose any research on this topic. There will be no reqirment to send a final complete paper as proceedings for the workshop will not be published! You will have the possiblity to present your research in an oral presentation or in a poster presentation.
Abstracts should be prepared using the CIE Abstract Template  and submitted to  - deadline for this is February 22, 2018.
