Book Description
Several factors are considered within engineering studies when determining the posted speed limit, including the 85th percentile speed, which is based on the driving behavior of most drivers (85 percent). The 85th percentile speed is believed to represent a safe speed that would minimize crashes. The TRB National Cooperative Highway Research Program's NCHRP Research Report 966: Posted Speed Limit Setting Procedure and Tool: User Guide provides and explains a speed limit setting procedure (SLS-Procedure) that considers factors beyond the 85th percentile speed, including both driver speed choice and safety associated with the roadway. This report also provides instructions for using an automated version of the SLS-Procedure via a spreadsheet-based Speed Limit Setting Tool (SLS-Tool). Two versions of the SLS-Tool are available: N17-76 SLS-Tool (with macros) and N17-76 SLS-Tool (without macros). The "without macros" version is made available for users who are not able to use macro codes on their computers. Please see the User Guide for more detailed information on using both versions of the SLS-Tool. The report is also accompanied by NCHRP Web-Only Document 291: Development of a Posted Speed Limit Setting Procedure and Tool, which documents the research efforts of NCHRP Project 17-76 - Guidance for the Setting of Speed Limits and a Presentation that offers an overview of the project.

Book Description
Several types of speed limits exist, including statutory speed limit, posted speed limit, school zone speed limit, work zone speed limit, variable speed limit, and advisory speed. The TRB National Cooperative Highway Research Program's NCHRP Web-Only Document 291: Development of a Posted Speed Limit Setting Procedure and Tool documents the research efforts and findings from an NCHRP Project 17-76 to identify factors that influence a driver’s operating speed and the development of a Speed Limit Setting Procedure and Tool. The document is supplemental to NCHRP Research Report 966: Posted Speed Limit Setting Procedure and Tool: User Guide.

Book Description
TRB Special Report 254 - Managing Speed: Review of Current Practices for Setting and Enforcing Speed Limits reviews practices for setting and enforcing speed limits on all types of roads and provides guidance to state and local governments on appropriate methods of setting speed limits and related enforcement strategies. Following an executive summary, the report is presented in six chapters and five appendices.

Book Description
"This informational report describes four primary practices and methodologies (engineering approach, expert systems, optimization, and injury minimization) that are used in establishing speed limits. It also reviews the basic legalities of speed limits and presents several case studies for setting speed limits on a variety of roads"--Provided by publisher.

Book Description
Speeding is the number one road safety problem in a large number of OECD/ECMT countries. It is responsible for around one third of the current, unacceptably high levels of road fatalities. Speeding has an impact not only on accidents but also on the ...

Book Description
Traditionally, Minnesota's posted speed limits are determined using the Institute of Transportation Engineers methodology as well as other considerations. The ITE methodology uses field measurements to evaluate roadway segments for the speed at or below which 85 percent of free flowing vehicles are traveling. MnDOT has observed that the ITE methodology often determines a higher operational speed for two-lane rural highways than MnDOT believes is warranted by other engineering and safety considerations. Further, MnDOT is being asked to justify posted limits of 55 mph when statutory limits for such roadways in Minnesota are 65 mph. Consequently, MnDOT would like to identify alternative methods used for determining posted speed limits that produce greater compliance by motorists.
