At the 2004 workshop, confirmed at the 2007 workshop, we determined that no product in our line (or anyone else's line) would suffice. The needs of pedestrians with limited vision or mobility issues demanded new devices.
"Longitudinal Channelizing Devices shall be interlocked to delineate or channelize flow.
The interlocking devices shall not have gaps that allow pedestrians to stray from the channelizing path."
SafetyRail and SafetyWall can be used as individual barricades, or as interlocking Longitudinal Channelizing Devices.
