Preferential and Managed Lane Signs and General Information Signs
2009 Edition Page 253 CHAPTER 2G. PREFERENTIAL AND MANAGED LANE SIGNS Section 2G.01 Scope Support: 01 Preferential lanes are lanes designated for special traffic uses such as high-occupancy vehicles (HOVs), light rail, buses, taxis, or bicycles. Preferential lane treatments might be as simple as restricting a turning lane to a certain class of vehicles during peak periods, or as sophisticated as providing a separate roadway system within a highway corridor for certain vehicles. 02 Preferential lanes might be barrier-separated (on a separate alignment or physically separated from the other travel lanes by a barrier or median), buffer-separated (separated from the adjacent general-purpose lanes only by a narrow buffer area created with longitudinal pavement markings), or contiguous (separated from the adjacent general-purpose lanes only by a lane line). Preferential lanes might allow continuous access with the adjacent general-purpose lanes or restrict access only to designated locations. Preferential lanes might be operated in a constant direction or operated as reversible lanes. Some reversible preferential lanes on a divided highway might be operated counter-flow to the direction of traffic on the immediately adjacent general-purpose lanes. 03 Preferential lanes might be operated on a 24-hour basis, for extended periods of the day, during peak travel periods only, during special events, or during other activities. 04 Open-road tolling lanes and toll plaza lanes that segregate traffic based on payment method are not considered preferential lanes. Chapter 2F contains information regarding signing of open-road tolling lanes and toll plaza lanes. 05 Managed lanes typically restrict access with the adjacent general-purpose lanes to designated locations only. -

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. -
DE MUTCD Page 3A-1 DRAFT Revision 3, October 2017
DE MUTCD Page 3A-1 CHAPTER 3A. GENERAL Section 3A.01 Functions and Limitations Support: 01 Markings on highways and on private roads open to public travel have important functions in providing guidance and information for the road user. Major marking types include pavement and curb markings, delineators, colored pavements, channelizing devices, and islands. In some cases, markings are used to supplement other traffic control devices such as signs, signals, and other markings. In other instances, markings are used alone to effectively convey regulations, guidance, or warnings in ways not obtainable by the use of other devices. 02 Markings have limitations. Visibility of the markings can be limited by snow, debris, and water on or adjacent to the markings. Marking durability is affected by material characteristics, traffic volumes, weather, and location. However, under most highway conditions, markings provide important information while allowing minimal diversion of attention from the roadway. Section 3A.02 Standardization of Application Standard: 01 Each standard marking shall be used only to convey the meaning prescribed for that marking in this Manual. When used for applications not described in this Manual, markings shall conform in all respects to the principles and standards set forth in this Manual. Guidance: 02 Before any new highway, private road open to public travel (see definition in Section 1A.13), paved detour, or temporary route is opened to public travel, all necessary markings should be in place. Standard: 03 Markings that must be visible at night shall be retroreflective unless ambient illumination assures that the markings are adequately visible. All markings on Interstate highways shall be retroreflective. -

Abstract Transportation agencies around the nation find themselves pushing the envelope of innovation to keep up with congestion caused by exploding demand for limited roadway space. Managed lanes provide a mechanism for harnessing the potential of the current infrastructure. Special-purpose lanes, including high- occupancy vehicle (HOV) and high-occupancy toll (HOT) lanes, allow engineers to manipulate roadway parameters to achieve varying levels of service. Managed lanes are controlled access facilities, and must somehow -
