Most low-cost retrofits for bicycle and pedestrian improvements involve pavement markings, whether striping a crosswalk or a bike lane or colorizing a conflict zone. This presentation will examine the effectiveness of different pavement marking materials including factors like durability, winter maintenance issues, retro-reflectivity, slip resistance and accessibility with a particular focus on application for innovative markings such as colorized paint and specialized symbols. The session includes an overview of MUTCD guidance on pavement marking materials, a presentation from Los Angeles that discusses an evaluation and comparison of different materials for green lanes, and information from Chicago related to the effect of winter conditions on pavement markings.

Presenters are Zaki Mustafa, Executive Officer, Project Delivery, LADOT; Nathan Roseberry, Senior Transportation Engineer, T.Y. Lin; and Bill Schultheiss, Senior Engineer, Toole Design Group.
