  • Improvements in Surface Transportation Signing
    Improvements in Surface Transportation Signing A chronological overview of designs, research and field studies that includes the development of the Clearview type system and related application concepts to improve the consistency, performance, and visual quality of traffic control devices. Prepared for: Mr. Gregory Nadeau Mr. Mark Kehrli Administrator Director Office of the Administrator Transportation Operations Federal Highway Administration Federal Highway Administration Mr. Jeffrey Lindley Mr. Kevin Sylvester Associate Administrator MUTCD Office Office of Operations Federal Highway Administration Federal Highway Administration Prepared by: March 21, 2016 Donald T. Meeker, F. SEGD Meeker & Associates, Inc. Larchmont, NY This body of work started at this sleepy intersection off of I-84 in the state of Oregon. As part of a motorist information project for the Oregon Department of Transportation (ODOT), I was finally forced to look for the answers to questions that I had wondered for years. Why? 1) Why is the structure of this information so eclectic and seemingly dysfunctional? 2) We are taught that mixed case would be more readable (why isn’t book/magazine/newspaper text published in all upper case?); so why are conventional road guide sign destination names in all upper case letters? 3) Why is the destination name on that freeway guide sign so fat? Why does it appear that you can’t fit your finger through the center space of the small “e” and the letterforms chunk up when viewed at a distance? 2 3 A lot of information competing for your attention yet created as if it is to stand alone! And Oregon is not alone.

  • Chapter 2 Signs
    Chapter 2 Signs 2-1 General Effective signing is the primary method to provide regulatory, warning, and guidance information to transportation system users (motorized vehicles, pedestrians, and bicyclists). Signing that is clear, concise, and accurate supports safe behaviors and safe operation, legal, and orderly travel on public roadways and transportation facilities. Sign use must be limited and conservative since signs can lose their effectiveness when used to excess. Signs are not typically used to confirm Rules of the Road. This chapter contains information about signing on the state highway system and is intended for persons involved in traffic operations or traffic design. Specific policies and guidelines are included that clarify the Manual on Uniform Traffic Control Devices (MUTCD) information. Situations not addressed in this chapter or the MUTCD may need to be determined on a case-by-case basis using engineering judgment. Where a change to the current sign installation is indicated by information in this chapter, replace as the current sign’s service life is reached. For MUTCD Target Compliance Dates, see page I-4, Table I-2 for required sign replacements. State law requires the department to adopt uniform standards for traffic control devices, including signs, along public roadways. WAC 468-95 adopts the MUTCD and Washington State Modifications to the MUTCD as these standards. The MUTCD and WSDOT modifications provide guidance on the intended use and placement of regulatory, warning, guide, and motorist information signs, as well as specific information on sizes and installation. This chapter supplements the MUTCD and WSDOT modifications with specific interpretations and unique applications for signs on the state highway system.

  • Specific Service Signs Shall Be Defined As Guide Signs
    Proposed Revision No. 2 Page 2F-1 CHAPTER 2F. SPECIFIC SERVICE SIGNS Section 2F.01 Eligibility Standard: Specific Service signs shall be defined as guide signs that provide road users with business identification and directional information for services and for eligible attractions. Guidance: The use of Specific Service signs should be limited to areas primarily rural in character or to areas where adequate sign spacing can be maintained. Option: Where an engineering study determines a need, Specific Service signs may be used on any class of highways. Guidance: Specific Service signs should not be installed at an interchange where the road user cannot conveniently reenter the freeway or expressway and continue in the same direction of travel. Standard: Eligible service facilities shall comply with laws concerning the provisions of public accommodations without regard to race, religion, color, age, sex, or national origin, and laws concerning the licensing and approval of service facilities. The attraction services shall include only facilities which have the primary purpose of providing amusement, historical, cultural, or leisure activities to the public. Guidance: Distances to eligible services should not exceed 5 km (3 mi) in either direction. Option: If, within the 5 km (3 mi) limit, facilities for the services being considered are not available or choose not to participate in the program, the limit of eligibility may be extended in 5 km (3 mi) increments until one or more facilities for the services being considered chooses to participate, or until 25 km (15 mi) is reached, whichever comes first. Page 2F-2 Proposed Revision No. 2 Guidance: If State or local agencies elect to provide Specific Service signing, there should be a statewide policy for such signing and criteria for the availability of the various types of services.
