Accurate traffic counts are important for budgeting, traffic planning, and roadway design. With thousands of centerline miles of roadways, it is not possible to install continuous counters at all locations of interest (e.g., intersections). Therefore, at the vast majority of locations, MnDOT samples axle counts for short durations, called portable traffic...

This report is part of the Human Factors for Connected Vehicles (HFCV) research program, whose goal is to minimize driver workload by eliminating connected vehicle (CV) device-related distractions. The research described in this document is part of an effort to develop initial design guidance for vehicle-to-infrastructure (V2I) safety messages provided using...

The purpose of this state-of-the-practice review is to identify the current use of data by metropolitan planning organizations to perform planning for operations activities. This information will be used to develop the virtual data access framework and to help establish requirements for the data that should be accessible by planning agencies via the framework....

Minnesota county engineers have sometimes observed heaves and dips near centerline culverts during cold winter months. In these instances, during the late winter and early spring, the area where a culvert has been replaced does not heave or heaves only slightly, while the roadway on either side of the replaced culvert heaves. The heave and dip disappear...

Anecdotal information indicates that private investment and property value increases are associated with featured Complete Streets projects. However, to date, little research has been done to confirm these benefits. Much of the relevant literature focuses on very real and important improvements to the safety of all who use Complete Streets: pedestrians,...

While pricing of managed lanes has been in place for over 20 years, most of the projects have been conversions of existing high-occupancy vehicle (HOV) lanes into high-occupancy-toll (HOT) lanes. These are the first generation projects.
This primer explores the evolution of first-generation pricing strategies into more complex express toll lanes using new...

Public agencies are required by state and federal laws to provide accessibility on their right-of-way (ROW). Failure of public agencies to provide accessibility on their ROW has resulted in costly settlements. Accordingly, the Illinois Department of Transportation (IDOT) needs to provide information for local public agencies, consultants, contractors, and IDOT...

This report presents a consistent methodology to evaluate and report ITS asset performance from the road user perspective.
It reviews current ITS performance evaluation practices amongst Austroads and road agencies. VicRoads methodology was adopted and generalised, and a five-step framework was established to retrieve, analyse and report on asset...

Rural communities cover much of the United States, but often grow at a slower rate than metropolitan areas. Smart growth approaches to development can help these places strengthen their economies while protecting their environment and residents’ health. For example, encouraging compact development allows people to drive less if they choose, reducing air...

This study evaluated alternatives to raised/non-traversable medians on driveways and approaches. Raised medians are often considered as an effective technique to limit direct left-turns that may be due to a significant number of conflict points. The raised medians provide an added benefit of improved corridor aesthetics. This research effort specifically...
