MASTER OF SCIENCESnow coverage of streets in Anchorage, Alaska, can visually block pedestrians and
drivers from viewing painted crosswalk demarcations. This study investigates the
potential of utilizing light projected onto the snow’s surface to mimic the intended
demarcation of the painted demarcation during snow coverage.
This is investigated via hypothetically fitting an existing crosswalk location with
available-for-purchase manufactured light projectors. The configuration is then
evaluated for angle of light projection, discomfort glare, and contrast.
The proposed installation is found to be theoretically acceptable. However, further
analysis could be performed regarding effective visual detection of contrast during
driving conditions and regarding acceptable levels of disability glare.Signature Page / Title Page / Abstract / Table of Contents / List of Figures / List of Tables / Introduction / Terms and Definitions / Existing Dimensions / Proposed Projector Installation / Light Analysis / Conclusion / Reference
