Investigation    \nCaltrans Division of Research and Innovation Produced by CTC & Associates LLC  \nFreeway Exit Gore Signage:  \nA Survey of State Practice and Related Research  \nRequested by  \nDonald E. Howe, PE, Signs Functional Manager, Caltrans Division of Traffic Operations  \nDecember 12, 2013  \nThe Caltrans Division of Research and Innovation (DRI) receives and evaluates numerous research problem statements for funding every year. DRI conducts Preliminary Investigations on these problem statements to better scope and prioritize the proposed research in light of existing credible work on the topics nationally and internationally. Online and print sources for Preliminary Investigations include the National Cooperative Highway Research Program (NCHRP) and other Transportation Research Board (TRB) programs, the American Association of State Highway and Transportation Officials (AASHTO), the research and practices of other transportation agencies, and related academic and industry research. The views and conclusions in cited works, while generally peer reviewed or published by authoritative sources, may not be accepted without qualification by all experts in the field.  \nExecutive Summary  \nBackground  \nThe Manual on Uniform Traffic Control Devices (MUTCD), published by the Federal Highway Administration (FHWA), defines the standards used by road managers nationwide to install and maintain traffic control devices on all public streets, highways, bikeways and private roads open to public traffic.  \nSection 2E.37 of the MUTCD,“Exit Gore Signs,” defines the gore as “the area located between the main roadway and the ramp just beyond where the ramp branches from the main roadway.”1 The exit gore sign indicates the exiting point, or place of departure from the main roadway. The MUTCD further specifies that an exit gore sign “shall be located in the gore and shall carry the word EXIT or EXIT XX (if interchange numbering is used) and an appropriate upward slanting arrow.”  \nInstalling and repairing exit gore signs are high-risk activities for Caltrans maintenance personnel, requiring field personnel to perform the work on foot, with limited protection and in close proximity to traffic. The space for working is small, making it difficult to use barriers or shadow vehicles for protection without closing lanes. Caltrans would like to identify options for relocating exit gore signs or using innovative products that can improve safety for field personnel while complying with California MUTCD requirements.  \nIn support of Caltrans’ inquiry, this Preliminary Investigation aims to identify alternative placement methods or other practices for signing freeway exits through a survey of state departments of transportation (DOTs) and an examination of related research.  \n1 Chapter 2E,“Guide Signs—Freeways and Expressways,” Manual on Uniform Traffic Control Devices, 2009 Edition including Revisions 1 and 2, FHWA, page 222, May 2012; [http://mutcd.fhwa.dot.gov/pdfs/2009r1r2/mutcd09r1r2editionhl.pdf](http://mutcd.fhwa.dot.gov/pdfs/2009r1r2/mutcd09r1r2editionhl.pdf).  \nSummary of Findings  \nThis Preliminary Investigation is organized into three sections:  \n• Exit Gore Sign Policy.  \n• Survey of Current Practice.  \n• Related Research.  \nFollowing is a summary of findings by section.  \nExit Gore Sign Policy  \n• National guidance on exit gore signs appears in the 2009 edition of the MUTCD.  \n• California MUTCD, published January 13, 2012, provides state-specific guidance for exit gore signs.  \n• Sign specifications are provided for numbered exit gore signs described in the MUTCD and the two in use in California, per the CA MUTCD.  \nSurvey of Current Practice  \n• Eighteen state DOTs responded to an eight-question survey that addressed alternatives used by these agencies for exit gore sign placement.  \no Two-thirds ofthe respondents shared practices for alternative exit gore sign placement.  \no Brief follow-up interviews with seven survey respon","cbCaidHnzGiAamyC","https://ap.wps.com/l/cbCaidHnzGiAamyC","pdf",931827,28,"English","# Executive Summary\n## Background\n## Summary of Findings\n### Exit Gore Sign Policy\n### Survey of Current Practice\n### Related Research","[{\"question\":\"What does the MUTCD define as the gore area for exit gore signs?\",\"answer\":\"The MUTCD defines the gore as the area between the main roadway and the ramp just beyond where the ramp branches from the main roadway.\"},{\"question\":\"What are the key requirements for exit gore signs under the MUTCD?\",\"answer\":\"An exit gore sign shall be located in the gore and carry the word EXIT or EXIT XX when interchange numbering is used, with an appropriate upward slanting arrow.\"},{\"question\":\"Why does Caltrans seek alternative placement or innovative products for exit gore signs?\",\"answer\":\"Installing and repairing exit gore signs is high-risk for Caltrans maintenance personnel due to work on foot with limited protection in close proximity to traffic, combined with small working space that complicates barrier or shadow-vehicle protection.\"}]","Freeway Exit Gore Signage - A Survey of State Practice and Related Research | PDF",1789723731,71]
