Additionally, current work zone TL-3 and TL-2 approved positive protection devices were summarized including longitudinal barriers, mobile barriers, vehicle arresting systems and end protection systems. Next, a nation-wide survey of state highway agencies was conducted to summarize current guidance relating to positive protection or changes in guidance to comply with Temporary Traffic Control Devices 23 CFR 630 Subpart K.
