Minnesota Department of Transportation Speed Limit Post-implementation Driver Evaluation Study


Book Description

The Minnesota Department of Transportation (Mn/DOT) raised speed limits on selected highways in September 2005. In conjunction with increased speed limits was an increased presence of enforcement. The overall objective of this market research project was to conduct a pre and post evaluation of drivers' reactions to these increases. The initial phase of this two-phase approach was conducted to establish a benchmark of selected measures. The second phase was conducted in August of 2006 after it was determined that the speed limits had been increased and driving conditions has stabilized.

Connected Vehicles for Safety, Mobility, and User Fees


Book Description

In 2007 Minnesota legislature approved a 5,000,000 project in order to demonstrate technologies which will allow for the future replacement of the gas tax with a fuel-neutral mileage charge. The Minnesota Department of Transportation (MnDOT) organized a study to examine the implementation and operation of a mileage based user fee program (MBUF), which might allow for the supplementation or replacement of traditional gas taxes. The primary objectives of the study were to: assess the feasibility of using consumer devices for implementing Connected Vehicle and MBUF applications. These applications included localized in-vehicle signing for improving safety, especially for rural areas, and the demonstration of the proposed Connected Vehicle approach for providing location-specific traveler information and collecting vehicle probe data. The study consisted of 500 voluntary participants, equipped with an in-vehicle system comprised of entirely commercially available components, primarily a smartphone using an application capable of tracking participant vehicle trips. Successfully meeting its primary objectives, the system was capable of assigning variable mileage fees determined by user location or time of day, as well as presenting in-vehicle safety notifications which had measureable effect on the participants driving habits. MnDOT contracted Science Applications International Corporation (SAIC) to perform research for the project and an evaluation of its findings. This document is the final report from SAIC, providing a summary of the study, its findings and an evaluation of the project as a whole.
