One last follow up before Monday’s meeting

Kevin Green from Adams asked that I pass along this information related to ambient light.  Looking forward to seeing everyone on Monday!


Brightness – Digtal Signs vs Other Illuminations


Documents for Monday’s Meeting– Illumination

Attached to this post is information to review ahead of Monday’s meeting.  The first three documents are from the guest speaker, Michael Woznicki.  Michael was recommended by industry folks, though he does not work for Adams or anyone in Kalamazoo directly, and was used by other municipalities in understanding how the industry measures illumination.  Here is his description of the information from Michael:

“I’ve attached a couple of documents that give examples of typical light levels for different areas, as well as the Illumination Engineering Society’s standard for acceptable light trespass in an urban setting. I’ve also included a study I did last year that depicts the addition of illuminance from a proposed billboard onto both the expressway and adjacent residential area, relative to existing roadway lighting.

Basically these documents will help give a framework of the type of lighting levels we’re looking at.”

Here are the documents:

And I spoke with some board members from Scenic Michigan to get a point-counterpoint idea about illumination as it relates to the surrounding environment, and they passed along this study:

Digital Billboard Illumination Study

And finally, Kevin Green from Adams asked that this information be passed along:


Photometric units

Please let me know if you have any questions, and we look forward to seeing you on Monday!

Follow Up From Last Meeting

There are a couple of loose ends from the March 25th meeting to address.  The first is a request for the Philadelphia study which talks about traffic safety that Brian Peterson referenced.

The second is the full text of the AASHTO ( American Association of State Highway and Transportation Officials) guide to digital advertising:

And finally, there was discussion about the Highway Beautification Act.  It was very difficult to find a discrete PDF of the act itself, but I found this site very helpful, with a lot of great links:  Federal Highway Administration Overview of the HBA

Additionally, here is a PDF of the agreement between the federal government and Michigan, related to enforcement of the HBA:

1965 Agreement HBA

We will update this site tomorrow with an agenda for the meeting on Monday, April 8th with information about illumination.
