  • 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.

  • Font Design for Street Name Signs
    PennDOT LTAP technical INFORMATION SHEET Font DesigN for Street Name SIgns #174 The Federal Highway Administration (FHWA) has terminated its approval of the Clearview Highway font, summer/2016 which PennDOT had specified as the standard font for freeway guide signs and conventional highway street name signs. Standard Alphabets for Traffic Control Devices, more commonly referred to as Highway Gothic, is now the only approved font for the design of traffic signs. FHWA has not issued a mandate on the replacement of signs using the Clearview font, but all future sign installations are to use the Highway Gothic font. This means existing signs may remain in use for their normal service life but should be replaced with a sign using Highway Gothic, when appropriate, as part of routine maintenance. Highway Gothic is a modified version of the standard Gothic font and was originally developed in the late 1940s by the California Department of Transportation. The font has six configurations known as letter series (B, C, D, E, E (modified), and F). Each series increasingly widens the individual letter sizing and expands the spacing between the letters. D3-1 street name sign with Street name signs (D3-1) and most other guide signs must be Highway Gothic font. designed separately because of variability in the message or legend that limits the ability to standardize sizes. PennDOT Publication 236, Handbook of Approved Signs, provides the minimum requirements for street name signs (D3-1). Additionally, the 2009 Manual on Uniform Traffic Control Devices (MUTCD) states that letters used on street name signs (D3-1) must be composed of a combination of lowercase letters with initial uppercase letters.

  • Change List for the 2003 Edition of the MUTCD
    Change List for the 2003 Edition of the MUTCD This change list was developed to acquaint readers of the 2003 Edition of the Manual on Uniform Traffic Control Devices (MUTCD) with the significant changes that have been incorporated into the MUTCD since the Errata Version of the 2000 MUTCD was placed on FHWA’s MUTCD website on June 14, 2001. This change list compares the 2003 MUTCD to the Errata Version of the 2000 MUTCD, which was the version that was printed and sold by AASHTO, ATSSA, and ITE. The changes regarding the application of accessible pedestrian signals that were incorporated into the 2000 MUTCD in July 2002 as Revision 1 are included in this change list and are clearly marked as “Revision 1 changes”. All references to Parts, Chapters, Sections, figures, tables, paragraphs, items, and pages in this change list refer to the 2003 MUTCD, unless specifically stated otherwise for a particular reference. General Items A new cover design was developed for the 2003 Edition of the MUTCD in order to make it easily distinguishable from the 2000 Edition. An individual cover design (with a similar theme as the overall cover) was developed for each of the ten Parts. The format of the pages was changed in order to significantly reduce the overall number of pages in the MUTCD. Margins were decreased and the amount of space between lines and paragraphs was decreased. All text is now in 11-point font size, including Standards and Guidance, which were in 12-point font size in the 2000 MUTCD. As a result of these various format changes, there is a lot less “white space” on most of the pages.
