Demonstration shows off barriers
The Federal Highway Administration (FHWA) further addressed the need for longitudinal channelizing barricades by partnering with the American Traffic Safety Services Association to sponsor the first-ever Pedestrian Accommodation and Delineation Devices Demonstration. This outdoor event took place at the FHWA Turner-Fairbanks Research Center on Sept. 22, 2004, in Washington, D.C.
Various longitudinal channelizing barricades were displayed in a simulated work zone walkway; visually and physically disabled individuals then walked or used wheelchairs in the simulated work zone area and tested the effectiveness of different devices. Manufacturers demonstrated existing, modified, or prototype devices in an effort to create safer work zones for all pedestrians. They were also encouraged to enhance or modify existing products to adapt to the new FHWA guidelines.
