About the Event

In a follow up to a March webinar, Economic Impacts of Freeway Corridors, this in-person event will share preliminary findings from an ongoing MnDOT research project studying the economic impacts of freeway corridors. There are many discussions about rethinking freeway corridor designs in Minnesota and nationally. Economic impacts should be considered when selecting a design alternative, but these are difficult to quantify. This research aims to provide a framework to better estimate the impacts of freeway corridor alternative projects by also considering mode, scale, land uses, community engagement practices, and environmental impacts.

Sponsored by the Institute for Urban and Regional Infrastructure Finance (IURIF) at the Humphrey School of Public Affairs, this event will focus on community engagement around infrastructure transformation. Presenters will discuss the intersection of 38th and Chicago in Minneapolis and share insights about how MnDOT approaches engagement for projects in Northeast Minnesota. In addition, IURIF researchers will lead an open discussion of each facet of the research around the economic impacts of freeway corridors, including community engagement, land use, environmental aspects, and socioeconomic impacts.

Preparing the Transportation Workforce for Emerging Technologies: A Guide

Leave a comment

Transportation agencies are facing rapid technological change—from artificial intelligence and machine learning to connected and automated vehicles, data governance, cybersecurity, advanced communications, and emerging analytical tools. These technologies are transforming how transportation systems are planned, operated, and maintained, while simultaneously reshaping workforce needs. This guide from the National Cooperative Highway Research Program offers practical strategies and resources to recruit, develop, and retain a workforce capable of adopting and leveraging emerging technologies.

Industry Challenges

As new technologies proliferate, agencies struggle with a number of overlapping challenges.

  • Outdated organizational structures and siloed departments
  • Skill gaps in advanced technical areas
  • Difficulty competing with private-sector salaries
  • Limited awareness of transportation tech careers among students
  • Pipeline shortages due to retirements and evolving skill demands

The guide categorizes these challenges into three core areas: Institutional Agility, Staffing Adaptability, and Workforce Pipeline.

1. Institutional Agility

Agencies must evolve organizational flexibility to integrate new technologies into their existing practices. There are a number of steps they can take to help with this.

  • Build multidisciplinary teams to break down silos and improve collaboration across planning, operations, IT, and field staff.
  • Modernize organizational structures and culture, including job rotations, co-location, communities of practice, refreshed licensure requirements, and skills-based management.
  • Develop business cases for new positions, such as data analysts, AI specialists, cybersecurity roles, and system engineers.
  • Enhance benefits packages beyond salary—highlight flexibility, professional development, hybrid schedules, innovation opportunities, and mentorship.

2. Staffing Adaptability

While the agency must modernize its processes, it must also provide a way for staff to develop the required skills to navigate new requirements. Should they hire, contract, or provide development channels for existing staff? The report has some suggestions.

  • Identify and formalize emerging positions across traffic operations, data analysis, IT/OT, hardware maintenance, policy/innovation, and design/construction.
  • Use a decision tool to determine whether to upskill current staff, hire new staff, or outsource work based on urgency, core function, and internal capacity.
  • Develop and promote new career paths that incorporate technical and soft skills, including leadership, communication, and innovation.
  • Leverage vendor contracts to include staff training, system handoff support, and access to vendor training sessions.
  • Recruit from adjacent industries with transferable skills—IT, telecommunications, military, emergency management, gaming, and manufacturing.
  • Connect staff to professional organizations and national training programs to keep technology skills current.

3. Long-term Workforce Pipeline

In addition to responding to immediate needs in the organization, the agency should look at strengthening the long-term talent pipeline with education partners.

  • Build partnerships with K–12, community colleges, trade programs, and universities through advisory committees, career fairs, mentorship, and public awareness campaigns.
  • Expand internships, apprenticeships, faculty exchanges, and hands-on training opportunities in emerging technology areas.
  • Collaborate on curriculum modernization, integrating interdisciplinary programs that blend engineering, IT, data science, and policy.
  • Invest in or share technology labs, equipment, and research opportunities to expose learners to real-world systems.
  • Support research initiatives that incorporate workforce development, outreach, and student engagement.

Conclusion

Emerging technologies offer transformative benefits for transportation systems but realizing those benefits hinges on the workforce. Agencies must take proactive, structured steps to evolve their organizations, strengthen recruitment and retention strategies, and build sustainable talent pipelines. This guide provides a flexible, practical framework to help you look at your organization and think about how some of these ideas apply to it, and how they may help you develop your own strategy for improving how you prepare for emerging technologies.

New Project: Understanding How Parking Space Requirements Affect Vehicle Miles Traveled

Leave a comment

Minimum parking requirements were established in the mid-20th century to mitigate increased motor vehicle congestion but have the potential to contribute to urban sprawl, hinder development, and curb incentives for drivers to choose alternative travel modes. Eliminating or reducing these requirements can help remove excess parking supply, increase alternative modes such as transit ridership, reduce vehicle miles traveled (VMT), and enhance economic productivity. Decreasing VMTs directly mitigates emissions by reducing car travel distances and many VMT reduction strategies hold additional benefits such as increasing accessibility and reducing traffic congestion.

VMT reduction also plays a significant role in Minnesota’s efforts to reduce greenhouse gas emissions from the transportation sector. New legislation passed in 2023 requires reducing VMT up to 20% per capita by 2050. The impacts of parking space requirements or long-term benefits and challenges associated with modifying or removing these requirements have not been studied in Minnesota. This project will investigate, document, and advance the understanding of minimum parking requirements in Minnesota and the region and their impact on VMT reduction.

Researchers aim to establish recommended values based on differing types of land use and community context, e.g., urban, suburban, and rural within Minnesota. Specifically, this project will examine the long-term benefits and challenges presented by reducing and/or removing currently established parking space requirements with new or redevelopment projects, and opportunities for parking space reallocation with existing uses.

“This research aims to fill a critical knowledge gap, will modernize minimum parking requirements reduce vehicle miles traveled, and provide communities with more flexible land‑use options,” said Mark Vizecky, state aid operations engineer, State Aid for Local Transportation at MnDOT.

The Objectives:

  1. Perform literature reviews of historical and current practices, policy and requirements regarding parking space requirements in Minnesota and the Upper Midwest and of current best practices regarding parking space requirements and the impact parking has on land use and travel behavior.
  2. Interview local agencies and the League of Minnesota Cities to gain insight into current parking space practices, policies, and requirements across Minnesota.
  3. Conduct an online survey of business stakeholders to assess the potential economic impacts of parking policy changes regarding customer behavior, business density, operating costs, opportunity cost and sunk cost, and accessibility.
  4. Conduct a travel behavior and mode choice survey using a diverse group of daily commuters from Minnesota’s urban, suburban, and rural communities to understand the influence of parking policies on traveler behavior.
  5. Analyze survey responses using discrete choice modeling to develop utility equations for different parking requirements, which will help predict mode shifts and associated VMT reductions.
  6. Utilize travel demand model data from eight metropolitan planning organizations in Minnesota to assess how changes in parking requirements could impact VMT reduction.
  7. Analyze the sensitivity and data requirements for a parking space requirement that will be effective for local use and develop a toolkit for local municipalities to assess parking needs and the economic impacts of parking policies in local communities.

Research Partnership Award honors mobility planning app

Leave a comment

Reprinted from CTS News May 6, 2026

The limited public transit infrastructure often found in rural areas can make it difficult for residents to access essential services such as healthcare, education, and grocery shopping—especially those without personal vehicles or who are unable to drive. Mobility-as-a-Service (MaaS) is a platform that integrates multiple transportation options and booking/e-ticketing with a smartphone app. While MaaS has primarily been developed and deployed in urban areas, it also offers potential benefits for rural area residents, such as improving transportation access, reducing social isolation, and simplifying the passenger experience.

A study sponsored by the Minnesota Department of Transportation (MnDOT) assessing the benefits of deploying its MaaS app in southern Minnesota was honored with this year’s CTS Robert C. Johns Research Partnership Award.

MnDOT’s MaaS platform was implemented in southern Minnesota in March 2023 to streamline and promote transit use, incorporating features such as interactive trip planning and mobile payment. The study area is served by seven different transit agencies, covering seven small cities and the surrounding rural areas.  

Led by University of Minnesota Department of Civil, Environmental, and Geo- Engineering associate professor and CTS scholar Alireza Khani, the research team aimed to learn how residents benefited from having access to a variety of mobility options through the MaaS platform, as well as if the platform increased transit ridership and how it could be improved. 

“This work represents a collaborative effort to better understand how people, especially those in rural Minnesota without many transportation options, might engage with emerging transportation technologies, mainly mobility-as-a-service,” Khani said when accepting the award. “This project is about people, their mobility options, their choices, and how technology can support more efficient, equitable, and sustainable transportation.”

The research team worked closely with MnDOT’s project management team and the platform development team to address the unique challenges of rural MaaS. Recognizing that existing data was insufficient to capture rural transit nuances, the team developed specialized data-collection spreadsheets and protocols. By training local transit service providers to use these tools for one week for both pre- and post- MaaS deployment phases, the team obtained primary data to analyze rider behavior across both fixed-route and demand-responsive transit (DRT). They also used the data to evaluate equity and service quality for disadvantaged populations. This collaboration between the University and the providers ensured that the MaaS implementation was not only technically sound but also tailored to the specific operational realities of southern Minnesota’s transit landscape.

Analysis of booking and ride data provided a clearer picture of how people use transit and how both riders and providers felt about their experiences, informing areas for improvement by deploying MaaS. Results showed a notable ridership increase of 4.2 percent for DRT and paratransit services following MaaS deployment, compared to a marginal 0.2 percent increase in the control group. In addition, a before-and-after study of trip location data showed MaaS’s ability to boost transit service rates in areas with lower-income residents.

“This is a great example of academic partnership with the public and private sector in a really practical way,” McFadden said during the awards ceremony. “We have brought rural transit up to parity with a lot of the technology that has been common in urban settings for about the last decade. This project has been a leader and driven both the public and private sector to bring along our rural transit systems. And so everybody is getting access to the same information.”

The research results provided a thorough evaluation of the pilot and have been key in shaping future rural transit projects. The evaluation served as a proof-of-concept for MnDOT, directly informing the decision to expand the MaaS system to the entire state. Additionally, the methods and findings have been widely shared with the professional community and received national attention, “highlighting the broader relevance of what started here in Minnesota,” Khani added. By bridging the gap between a regional pilot and a statewide initiative, this research serves as a strategic roadmap for modernizing rural transit in Minnesota and beyond.

The Research Partnership Award is named in honor of former CTS director Robert Johns. The award is presented annually to a team of individuals who have collaboratively drawn on their diverse expertise to achieve significant impacts on transportation.

Rough roads? How everyday cars might help flag trouble spots

Leave a comment

Reprinted from CTS News, May 11, 2026

To assess pavement conditions throughout the state, the Minnesota Department of Transportation (MnDOT) uses a van specially equipped with advanced technology that measures roughness, cracking, and other signs of distress on a roadway’s surface. That system has its limitations, however. The vans cost about $800,000 each, and the data collection requires extensive coordination, trained personnel, and sensitive equipment that is limited to operating in warmer summer months. In addition, the data collection takes place once a year on MnDOT routes and every other year on County State Aid Highways.

Could there be a more efficient and more timely way to assess the state’s road pavement conditions? To find out, researchers at the University of Minnesota (UMN) explored whether data already being generated by everyday vehicles could enhance MnDOT’s current method. 

To test this, UMN researchers equipped study vehicles with a simple plug-in scanner that captured onboard diagnostics data, explains CTS scholar Raphael Stern, the project’s co-investigator and UMN associate professor of civil, environmental, and geo- engineering. Modern vehicles already have sensors that collect this data, which can be used to monitor and optimize vehicle performance. That same data could provide clues to how a vehicle is responding to pavement beneath it, he says.

“If we could show that this can be done in Minnesota, MnDOT or local agencies can implement this technology,” says lead investigator and CTS scholar Mihai Marasteanu. “They could have a very good idea about the conditions of pavement every day—not just once a year.”

For this project, researchers adapted methodologies from Denmark’s Live Road Assessment (LiRA) project, considered to be the most comprehensive effort to use onboard vehicle sensors for continuous pavement monitoring. That initiative provided insights into both the technical feasibility and practical challenges of extracting meaningful pavement quality metrics from standard vehicle data.

Researchers tested a similar approach on three routes in Minnesota to capture a diverse range of pavement conditions under real-world driving scenarios. One route was a 15-mile loop in the northeast Twin Cities metropolitan area that covered urban and suburban road segments with consistent traffic flow. Another was a 96-mile loop between Minneapolis and Northfield, comprising a mix of urban, suburban, and rural roadways. The third was the 2.6-mile loop at MnROAD, MnDOT’s research facility near Albertville.

The plug-in scanner collected data on vehicle location, speed, and 3D acceleration; the last measures the intensity and complexity of vibrations transmitted from the road through the vehicle’s suspension system.

Across the three routes, researchers collected more than 9,000 data points. Machine learning models used 694 data values to predict pavement quality using the International Roughness Index (IRI) for a given pavement section.

Researchers compared and validated predictions against data from MnDOT and a commercial pavement‑monitoring system. Results demonstrated a correlation across diverse road conditions, although accuracy decreased in areas where pavement conditions changed quickly or road surfaces had defects. Predictions were also more accurate on highway segments than local roads because of variable urban driving environments.

Of the eight learning models evaluated, one achieved 94 percent accuracy on predicting pavement roughness. The performance of each model varied based on environmental factors, data collection conditions, and road types.

The research successfully demonstrated that vehicle sensor data can effectively support continuous infrastructure monitoring, Marasteanu says. “It could save money in the long run and give a much more accurate representation of pavement conditions over the entire year,” he notes.

The project, funded by MnDOT, included implementation guidelines for large-scale deployment, equipment standardization protocols, data-processing pipelines, and risk-mitigation strategies.

MnDOT is now exploring how to extend the research beyond the study vehicles, says Curt Turgeon, director of MnDOT’s Office of Materials and Road Research. One way will be to use commercial data sources that already collect similar information from everyday vehicles. For example, NIRA Dynamics, headquartered in Sweden, partners with automakers Volkswagen and Volvo to collect anonymized sensor data from consumer vehicles. These data streams are captured continuously throughout the year.

“MnDOT has a contract with NIRA to determine how this data might enhance our pavement management decisions as well as potentially document snow and ice response,” he says. “They also have a module that may flag potholes or other in-road hazards based upon vehicles swerving.”

New Project: Using Satellite Technology to Monitor Ground Deformations Adjacent to Roads

1 Comment

Geohazards generated by ground movements (e.g., landslides, subsidence, sink holes, etc.) cause substantial damage and interruptions to Minnesota’s highway network. Reactive monitoring approaches and borehole-based instrument sensing both have limited spatial coverage and are limited to sites already known to be in distress. This research explores the establishment of continuous satellite-based InSAR monitoring of ground deformations adjacent to roads on a broad geographic scale that would enable detection of pending hazards before they develop into large failures.

To receive email updates about this project, visit MnDOT’s Office of Research & Innovation to subscribe.

This warning system will combine data from high spatial resolution InSAR measurements, optical remote sensing data, and deep learning algorithms to automatically detect and continuously monitor deformations across large spatial regions. The research team will create MnDOT training modules to demonstrate the utility of the deformation data and automated warning system.

InSAR monitoring is expected to improve the safety and reliability of Minnesota’s transportation system and reduce costs and delays associated with emergency repairs. It would also support the state’s geotechnical asset management program by assessing the feasibility of InSAR for tracking performance of geotechnical assets (e.g. retaining walls, slopes, pavement foundations, etc.).

“This research project will help us determine if InSAR technology is ready for prime time for transportation agencies as a remote sensing tool to track performance of assets,“ said Raul Velasquez, geomechanics research & deployment engineer at MnDOT’s Office of Materials and Road Research.

The Objectives:

  1. Develop an automated warning system that can alert MnDOT staff of areas where abnormal ground deformation (e.g., landslides, subsidence, and sinkholes) is occurring along Minnesota interstate highways, allowing them to proactively intervene.
  2. Assist MnDOT in continuing to build its geotechnical asset management program by assessing the feasibility of InSAR for tracking performance of geotechnical assets such as retaining walls, slopes, and pavement foundations.

Tuesday, May 19, 2026, 12:00–1:30 pm Virtual

REGISTER

About the Event 

Improving pedestrian safety requires a deeper understanding of how people interact with roadway design and infrastructure. This webinar will highlight two recent research efforts examining how transportation infrastructure influences driver behavior and pedestrian safety outcomes.

Curtis Craig, a research associate in the Human Factors Safety Laboratory, will present findings from two complementary studies examining infrastructure at intersections. The first study explored how right turn lane configurations affect pedestrian safety using a combination of behavioral analysis and multiple research methods. The second project examined how drivers and pedestrians respond to different infrastructure treatments and how those designs influence behavior in real-world environments.

These study findings offer transportation agencies, planners, and engineers practical considerations as they work to create safer and more accessible pedestrian environments.
