Construction Project Traffic Impact Analysis Methodology and DTA Model Validation

MnDOT has been working toward better understanding of traffic impacts and Road User Costs associated with reduced system capacity during construction activities. In an effort to quantify those impacts, a Dynamic Traffic Assignment (DTA) / Mesoscopic Travel demand model was developed within the DynusT/DynuStudio software platform. This model has been useful for quantifying these impacts among various construction phasing ...more »

Enhancement and Integration of the TeTRIS and TICAS Freeway Performance Tools

This project would integrate the TeTRIS and TICAS Freeway Performance Tools into one system. The Traffic Information & Condition Analysis System (TICAS) was developed for the RTMC several years ago to help extract RTMC freeway data and develop performance measures for the metro freeway system. TeTRIS is currently being developed to be able to monitor travel time reliability on metro freeways. This project would combine ...more »

Spatial Analysis of Agriculture Supply Chain to Assess Transportation Impacts

Efficient agriculture movement is critical to Minnesota’s economic health. In the past two decades, the agriculture supply chain experienced a number of market, technological, and policy innovations that have directly influenced the way producers and wholesalers navigate their local freight networks. With producers’ reliance on rural and urban roadways projected to grow, so too are concerns for accelerated pavement degradation, ...more »

Maintenance Operations

Implementation of Wet or Soft Soil Crossing Technology

Maintenance and construction operations need to cross and stage over wetlands or low bearing capacity soils to perform necessary state work. Various permits require wetland avoidance or minimization of impacts. Additional environmental commitments include minimizing or preventing soil compaction, preservation of soil function and structure, preservation of the native plant community, preservation of soil habitat for ground ...more »

Unmanned Aircraft Systems (UAS) - Pond and Stormsewer Inspection and Data Collection

MnDOT Metro District has over 600 stormwater ponds to manage. Unmanned Aircraft Systems (UAS) have proven beneficial for the inspection and maintenance of bridges. Could the same technology be used to assist Metro District in the management of these ponds? The ponds tend to be very difficult to survey. Most are overgrown with vegetation and to survey pond bottom a boat is required. We would like to develop a ...more »

Tactile Mapping Options for Increased Accessibility and Compliance

Evaluate methods to increase accessibility for the visually impaired to MnDOT information and products such as maps and information for public outreach for projects. Assemble a demographically diverse population of visually impaired individuals (low vision to no vision) and discuss with them their needs regarding transportation and transportation information. From these results develop a list of possible approaches ...more »

Frost/Heave addition to the MnPAVE Flexible Pavement Design Software

Addition of a frost model added to MnPAVE will allow users to review the pavement layers/design that were selected in MnPAVE and then verify if the pavement layers being considered are frost susceptible and may affect the long term performance over time. Local roads will benefit the most by having this module added to MnPAVE. MnROAD has worked with Sweden (Trafikerket) personnel to compare MnROAD low volume road test ...more »

Training Module for the Tailgate Test for Determining Appropriate Sediment-reducing Chemicals/Dosage

A training module for construction site field personnel is needed for a recently-completed project that developed a practical sediment control method for fine silt/clay sediment that is especially difficult to manage in runoff from construction sites. The Tailgate Test Kit quickly and easily identifies flocculants that reduce turbidity in construction stormwater discharge. The mobile test setup efficiently determines ...more »

Understanding Pedestrian Travel Behavior & Safety in Rural Settings

The purpose of this research is to improve our understanding of walking behavior and safety in rural MN communities by building upon MnDOT's success in creating a program to count people walking and biking. In particular, four tribal nations (Bois Forte, Fond du Lac, Mille Lacs, and Grand Portage) are collaborating with researchers at the University of Minnesota, as well as MnDOT district engineers and planners to: ...more »

Automated Weather-Savvy DMS Messages

According to the FHWA, “On average, there are over 5,748,000 vehicle crashes each year. Approximately 22% of these crashes - nearly 1,259,000 - are weather-related.” Inclement weather causes visibility impairments, as well as traction, stability, and maneuverability challenges for drivers. Together, these factors often result in a major increase in traffic collisions and incidents during winter storms and other weather ...more »

New Pedestrian Crossing and Gateway Treatment Idea

The pedestrian placard used on lower speed streets to remind drivers that they must stop for pedestrians (R1-6a and R1-6b) in the crosswalk has shown to be fairly effective at getting drivers to yield when used in series across the street (see power point presentation). This idea would be to add flashing lights around the border and tie these together with some type of RFID that will have them light up (either in strobe ...more »
