Abstract:

The Code of Federal Regulation (CFR) Title 23 Part 630 Subpart K - Temporary Traffic Control (630.1102–630.1110) rule states that positive protection shall be considered where work zone conditions place workers at increased risk from motorized traffic and where positive protection devices can significantly improve safety. This project developed Idaho-specific work zone positive protection guidelines that Idaho Transportation Department (ITD) staff can use when designing work zone traffic management plans. The guidelines address conditions where positive protection device (i.e. devices that contain and/or redirect vehicles and meet the federal crashworthiness evaluation criteria) application can be recommended on the basis of reduced work zone crash costs. For sites where such conditions do not exist, guidelines are provided regarding intrusion and crash reduction countermeasures (e.g., closer channelizing device spacing and supplemental speed management devices) that could be employed. These guidelines are based on the theory of encroachment hazard analysis, which was conducted using the Roadside Safety Analysis Program (Version 3, NCHRP 22-27, 2012).
