TPAR workshop and demonstration
In June 2010, MnDOT, partnered with ATSSA (American Traffic Safety Services Association) and Northland Chapter of ATSSA, conducted a training session to discuss the latest standards for providing TPAR facilities through work zone areas. The two-day event also included a TPAR device demonstration and provided an opportunity for people with disabilities to talk about the issues for disabled pedestrians in work zones. Attendees included representatives from several stakeholder groups including disabled pedestrians and/or their representatives, manufacturers of devices, public agencies responsible for pedestrian facilities, private contractors, and engineering organizations.
TPAR devices such as an audible message device, several types of pedestrian channelizers and two types of temporary curb ramps were on display for review. Attendees' opinions on the various devices were collected and will be used to develop future TPAR product specifications. Read a summary report (PDF) of the comments.
TPAR device focus group evaluation
To assist MnDOT and the Temporary Traffic Control Industry in developing compliant devices for TPAR applications, several known ADA products were gathered for the demo. The devices were reviewed by three focus groups of people with disabilities and professionals who train people with disabilities to be mobile. The market research interviews gathered information and opinions on the needs of the disabled pedestrians regarding the usefulness of the various TPAR devices (or how they may be improved) and their thoughts on work zone walkway detours.
