Traffic channelization devices have found new application at highway-rail grade crossings with active warning devices. Numerous studies conducted at locations where they have been installed show positive changes in unsafe driver behavior as a result of the treatments. When meeting certain requirements, traffic channelization devices and median barriers are an approved supplemental safety measure for the establishment of quiet zones. Traffic channelization devices are low cost and this makes them an attractive option for improving safety at highway-rail grade crossings.
