Innovative Winter Safety Research

Vertically Tilted Signs
The weather outside is frightful, and that can mean dangerous driving conditions. One danger is snow build up (accretion) on traffic signs. This has been a serious problem here in Nevada and elsewhere. Messages normally visible in non-snow conditions can be partially, or even entirely obliterated, causing a variety of problems for motorists, from inconvenience to life threatening. Distracted drivers pausing to read partially obscured signs and neglecting to pay attention to driving can also be dangerous. A completely missed sign such as “Stop” or “Do Not Enter” could be catastrophic.

One of the most innovative studies conducted by Nevada DOT examined the use of tilted signs to reduce snow accretion. Three sets of signs were installed each facing south, west and north. Each of the sign sets was vertically tilted at 0, 3, 6, 9 or 12 degrees. The sign messages contained the direction the sign faced and the degrees of vertical tilt. Findings indicated that, in fact, the degree of snow accretion decreased as the angle of tilt increased, although there were examples where little or no advantage was observed depending on wind direction or heavy snow fall. The study recommends the application of tilted signs in Nevada. The signs may still be seen year-round in Washoe Valley, just outside of Carson City.

Historical Resources

(Library Materials) Permanent link

The Research Library strives to deliver the most up to date information possible, through the latest publications and access to premium online databases.  But did you know, the library is also a treasure trove of historical information about NDOT (formerly the Department of Highways) and its important role in the development of the state? As NDOT approaches its one hundredth anniversary in 2017 the historical publications available in the Research Library will only become more relevant.

These four publications offer some of the most important insights into NDOT's past. 

Biennial Report of the Nevada Department of Highways (1917-1974)

Biennial Report of the State Department of Highways

Submitted by law every two years to the Nevada Legislature, the Biennial Report is rich with statistics and detailed descriptions of the accomplishments of each division.

 Laws Related to Highways and Roads (1937-2000)

Laws Relating to Highways and Roads

A go-to resource for researching the laws that shaped the Department and the state.

NDOT News (1964-2007)


The monthly newsletter of the Department, NDOT News offers a unique, behind the scenes look at the Department and its staff. 

Nevada Highways and Parks (1938-1983; became Nevada Magazine)

Nevada Highways and Parks

Published by the Department of Highways, Nevada Highways and Parks highlighted the wonders of Nevada, enticing tourists to venture out on its modern roads.


Interlibrary Loan

(Library Materials) Permanent link


Did you know that NDOT employees have the same access to high quality information enjoyed by students and faculty of large universities? It's true. Through our premier WorldShare Interlibrary Loan membership NDOT has borrowing access to literally BILLIONS of books, articles and industry standards, greatly expanding the reach of our library. 

To expand the reach of their own collections, libraries have long been eager to loan materials to one another, known as interlibrary loan. Now, with the all-electronic WorldShare, this process has become even quicker and more efficient than ever.

To date we have received academic journal articles on such topics as wind loads, prestressed concrete and accident prevention; books on bridge aesthetics, archaeology, sustainable street design and urban runoff; and industry standards from sound barriers to safety vests to escalators. 

We have received loans from other DOT libraries including California, Illinois, Iowa and Virginia, along with the US DOT Library; but we've also received loans from several academic libraries including the Naval Postgraduate School, California State University, Carnegie-Mellon and the College of the Siskiyous. We've even received loans form private corporate libraries.

So please make use of this important tool. To request an interlibrary loan call or email the Research Library.


Virtual Peer Exchange

 2015 Virtual Peer Exchange   2015 Virtual Peer Exchange Screen

The Nevada DOT Research Section is excited to join Idaho, South Dakota and Wyoming in the first state DOT virtual peer exchange. States are required to participate in peer exchanges every five years. This exchange is a pilot and is being watched and evaluated as a possible effective alternative to traditional face to face exchanges, that can be costly and time consuming.

New AASHTO Publications

(Library Materials) Permanent link

LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, 1st Edition          Mechanistic-Empirical Pavement Design Guide: A Manual of Practice, 2nd Edition

These new AASHTO publications represent significant updates to two important previous publications.  From the AASHTO website: 

LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, 1st Edition  
The first edition of the LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals incorporates and builds upon the design specifications found in the Sixth Edition of Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals, which it supersedes. The specification includes current research on LRFD calibration, loads, and resistances plus relevant specifications from other AASHTO documents. Completely new sections on Fabrication, Construction, Inspection, and Asset Management based upon best practices have also been added. 

Mechanistic-Empirical Pavement Design Guide: A Manual of Practice, 2nd Edition  
This manual describes a pavement design methodology, termed mechanistic-empirical (M-E) pavement design, that represents a major change from the pavement design methods in practice today. Based on engineering mechanics that have been validated through extensive road test performance data, the manual presents information necessary for pavement design engineers to begin using the MEPDG design and analysis method.”

Both books are available for checkout at the NDOT Research Library.
