Autonomous Vehicles: What Should Local Agencies Expect?
A new FAQ interactive resource guide helps local agencies prepare for and respond to Connected Autonomous Vehicle (CAV) changes.
System Preservation Guidance & Tools
This project produced an interactive guide that helps local agencies evaluate their transportation network preservation needs, communicate these needs to elected officials and the public, and select and implement strategies to address funding gaps.
Gravel Road Management Tool
A new spreadsheet tool was designed to help local agencies manage their gravel roads. It can be used to track maintenance and construction data, as well as to track costs and optimize spending.
Personal Protection Equipment Poster & Website
A technical resources website, with posters, fact-sheets and online resources, has been developed for the LRRB by the Minnesota LTAP program.
Tool for Prioritizing Pavement Markings on Low-Volume Roads
This spreadsheet-based decision-making tool will help local agencies establish effective maintenance practices to preserve pavement markings on low-traffic volume roads.
Fleet Management Tools for Local Agencies
This guidebook compares the eight most widely used fleet management software tools by Minnesota agencies. It also contains a survey of agencies’ fleet practices and replacement cycles.
New Video, Website Invite Kids to Explore World of Civil Engineering
Students can learn more about the field of civil engineering and how to become an engineer in a new video and website produced by the Local Road Research Board.
Sign Retroreflectivity: A Minnesota Toolkit
The Minnesota LRRB has developed a Sign Retro Reflectivity Toolkit to provide local governments,
especially small cities and townships, with guidance and resources to meet FHWA’s sign retroreflectivity deadlines.
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.
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.
Best Practices: Managing Interactions Between Local Authorities and Major Traffic Generators
This document presents guidelines for Minnesota county
engineers on how to interact with developers of “wind farms” (technically known as large wind energy conversion systems or LWECS). However, county engineers in other states, other road authorities, and wind power developers themselves also may find this information valuable.
Crash Mapping and Analysis Tool (Software)
The Minnesota Crash Mapping Analysis Tool (MnCMAT) enables users to analyze crash data based on a number of attributes.
Hot-Mix Asphalt Design Tool
The purpose of this Web tool is to assist the engineering community in the design of hot mix asphalt (HMA) pavements.
