Current guidelines and recommendations for the brightness of retroreflective road markings do not specifically address the emerging requirements of older drivers and range from a low of 90 mcd/m2/lux (Allen, O’Hanlon and McRuer, ) to a high of mcd/ m2/lux (Ethen and Woltman, ).

As the interstate highway system grew and engine size increased, horse trailers, particularly in North America, became more popular especially in the s and s.

[United States. Department of Transportation. Research and Special Programs Administration.;]. The evaluations indicated that any of the retroreflective systems tested improved rail car conspicuity when compared to a nonreflective marking.
The data suggest that bright colors distributed to give an indication of the size or shape of the rail car were most effective, and distributions that concentrated the markings along the lower side of Cited by: 2.

Edition Chapter 6F. Temporary Traffic Control Zone Devices Section 6F Types of Devices. Guidance: 01 The design and application of TTC devices used in TTC zones should consider the needs of all road users (motorists, bicyclists, and pedestrians), including those with disabilities.
Support: 02 FHWA policy requires that all roadside appurtenances such as traffic barriers, barrier. The retroreflective continuous delineation emphasizes lane shifts in low-visibility conditions.
As shown in the video above, applying wet reflective pavement markings for traffic changeovers can be critical to helping drivers navigate work zones safely—especially during rainy weather.
A decision by the Ohio Supreme Court illustrates the difficulty of fair application of the ACDA rule. The case involved a collision between a snowmobile and a dark flatbed rail car, which was blocking a grade crossing (Sharpe v.
Norfolk and Western, Sandusky, Ohio). The snowmobile traveled under the rail car killing the snowmobile by: Standard. Traffic control devices shall be defined as all signs, signals, markings, and other devices used to regulate, warn, or guide road users, placed on, over, or adjacent to a street, highway, private roads open to public travel (see definition in EPG ), pedestrian facility, or bikeway by authority of a public body or official having jurisdiction.
CHAPTER 6A. GENERAL Section 6A General. Support: Whenever the acronym "TTC" is used in this Chapter Part 6, it refers to "temporary traffic control.".

More importantly, the retroreflective markings attached to the limbs led to significantly longer (about %) recognition distances than when the retroreflective markings were attached to the torso.
or railroad stop procedures may be retroreflective material, as specified by each state. ROAD SPEED CONTROL When it is desired to accurately control vehicle maximum speed, a vehicle speed limiter may be utilized.
RUB RAILS A. There shall be one rub rail on each side of the bus located at, or no more than eight inches above, the seat cushion Size: 39MB. Section 3B (Curb Markings) states that retroreflective solid yellow markings should be placed on the curbs of islands that are located in the line of traffic flow where the curb serves to channel traffic to the right of the obstruction, and that retroreflective solid white markings should be used (on curbs) when traffic may pass on either.
Also, increasing the conspicuity of ONE WAY, WRONG WAY, and DO NOT ENTER signs by using larger-than-standard (MUTCD) size signs, and using retroreflective sheeting on these signs that provides for high brightness at the wide observation angles typical of the sign placements and distances at which these signs are viewed (e.g., + degrees) will.
The FHWA proposes to change the references to the book previously titled “Standard Highway Signs” to refer to the current “Standard Highway Signs and Markings.” This change is proposed throughout the MUTCD because the FHWA is changing the title of that book to more accurately reflect its content, which includes information regarding.
