TRB Access Management YouTube Channel

The TRB Access Management committee now has a YouTube Channel devoted to sharing the best information from

We are exploring the idea of creating short videos that highlight some of the most useful information to share about access management. This will provide practitioners a tool to find and share best practices. YouTube will provide an additional channel for us to "get the word out" about how access management can save lives and improve the efficiency of our transportation system.

Rob Sanders is a graduate student of Grant Schultz, who has created these three test videos. We hope to create many more, and encourage other's to "find the gold" and contribute to further development of this idea. Please provide comments below to help us in this effort.

Current Videos (through 12/27/17) include:
