Minnesota Research Test Section Tracking
The purpose of this Web tool is to assist the engineering community in the design of hot mix asphalt (HMA) pavements. The system archives information for others to build upon with the use of other test sections or performance or material testing databases being developed within the state.
Heavy Truck Impact Calculator
This Excel-based tool calculates the impact of a variety of heavy vehicles on local asphalt roads. The tool will help local agencies make informed decisions when developments such as construction, distribution centers or hauling routes create an unexpected increase in heavy vehicle traffic on a temporary or permanent basis, and it will aid in planning if these traffic increases can be predicted.
Training Module for Pavement
Over a period of many years, LRRB and FHWA Investigations have produced information relating to selecting the most effective Pavement Rehabilitation Strategies. In addition to these efforts, the FHWA has produced training modules incorporating Pavement Rehabilitation Selection methods. The objective of this task was to synthesize these efforts and develop a training module summarizing the best practices suitable for use by local agencies in Minnesota.
Implementation of Pavement Management in Minnesota
This resource will help local agencies without a Pavement Management System to evaluate, select, and justify the purchase and operational costs of a PMS; additionally, it will help local agencies who have a PMS to better use and enhance their capabilities.
Minnesota’s Best Practices and Policies for Safety Strategies on Highways and Local Roads
This handbook aims to reduce the number of severe crashes on the state’s highway system by helping agencies design, operate, and maintain their systems of roads and highways. A spinoff from the ongoing County Road Safety Plan efforts, this resource contains traffic safety strategies, sample policies and best practices information to support agencies as they implement their own policies.
Roundabout Myths (10-myth version)
In this video, we address common roundabout myths and demonstrate why they are a viable alternative for intersection traffic control.
Rumble Strips Noise Difference: Traditional vs Sinusoidal Designs
This video, shot near Thief River Falls, Minnesota, shows a comparison between traditional rumble strip designs and the newer sinusoidal rumble strips (a.k.a. “mumble strips”). Researchers are investigating whether sinusoidal rumble strip designs, which are much quieter, are effective enough to combat drowsy or inattentive driving.
Flashing Yellow Arrow Tool for Time-of-Day Use Instructional Video
This video accompanies a spreadsheet tool, which aims to assist local agencies in determining which hours of the day to consider using flashing yellow arrow (FYA) phasing.
Temporary Traffic Control
The documents that emerged from this research will help local agencies identify the appropriate work zone layout for low-volume roads based on the maintenance activity that will be performed.
LRRB Announces New Research Projects
The Minnesota Local Road Research Board (LRRB) recently announced its fiscal year 2017 projects. Together with the Minnesota Department of Transportation’s Transportation Research Innovation Group (TRIG), the two organizations selected […]
Flashing Yellow Arrow Tutorial Video
The LRRB recently developed a spreadsheet tool to help local agencies determine which hours of the day to consider using flashing yellow arrow (FYA) phasing. An instructional video has now been published to help agencies understand the methodology used to develop the spreadsheet, as well as how to use it.
Effects of Implements of Husbandry on Local Roads
The LRRB has produced a brochure that provides background information on the history of implements of husbandry; summarizes neighboring states’ weight restrictions; and provides links to recent research data on the damaging effects that large machinery has on pavements.
Guide for Rural Intersection Safety Technologies
A new guidebook is intended to help engineers select and deploy LED stop signs and ICWS at stop-controlled intersections.
Young Drivers Toolkit
This task aimed to integrate best practices from local, state and federal safety partners and help Minnesota cities and counties effectively address driver behavior.
