This report analyzes how state-funded highway improvement projects in the seven county Twin Cities metropolitan area affected businesses in adjacent Census Tracts. We first identify demographic factors associated with the temporal and financial prioritization of some projects over others, finding that the per capita income of a Census Tract is associated with it featuring more heavily prioritized highway improvement construction. We then turn to the effects of highway improvement construction and operation, using results from the previous analysis to account for endogeneity of improvement timing. While we find largely null results of highway improvement on sales, employment, establishment counts, and turnover for both single-establishment and multiple-establishment firms, we also find that pooling data masks several sources of effect heterogeneity. Specifically, we find that single-establishment firms experience negative sales effects from construction when tracts are affected only by infrastructure replacement projects (improvements that do not affect traffic operations, i.e., a bridge replacement). Furthermore, negative sales and employment effects occur after construction is completed for single-establishment firms in urban areas and in tracts affected by longer bouts of construction. Meanwhile, in suburban areas, some modest gains accrue to multiple-establishment firms. These results suggest that regional planners need to account for potential externalities from highway construction on particularly nearby small business establishments

Transportation systems, as integral parts of human settlements, reflect the societal structures and cultural ideologies influenced predominantly by the dominant race or class. In the absence of prioritizing the transportation needs of underserved communities, transportation systems may perpetuate systematic inequities. This study aims to address the inequities present in current transportation systems by conducting a comprehensive examination of the transportation experiences of individuals belonging to ten specific underserved communities. These communities include eight within the Twin Cities metropolitan region (Latinx, African American, Hmong, people with disabilities, immigrants, people living with HIV, single mothers, and single fathers), as well as two communities in the Greater Minnesota area (transitioning home residents in Fergus Falls and tribal members of the White Earth Nation). This research adopts a mixed-method approach, incorporating both qualitative interviews and quantitative smartphone-based travel behavior surveys. The findings reveal that each community faces distinct transportation barriers, alongside shared themes in transportation inequities such as inadequate public transportation, difficulties related to car use, and the impact of transportation on significant life outcomes. Recommendations for future research and practice are provided.

Gender can have a significant influence on people’s behaviors and experiences. Hence, excluding gender diversity in transportation research and practices can result in biased or incomplete understandings of issues and perceptions about transportation and quality of life. This study examined whether and how gender, in a broader sense, can result in distinctly different activity-travel patterns and subjective well-being (SWB) outcomes using survey data. The study reviewed existing literature and found that gender was not binary meaning that some gender identities were not solely female or male. The literature also indicated a person’s gender typically intersected with their other social identities such as race and family type and created unique needs and experiences. To address the complex nature of gender, the team collected new data using the Daynamica smartphone application and included specific questions concerning (1) participants’ gender identities and attitudes toward gender roles, (2) their share of household-supporting tasks in 14-day travel diaries, and (3) their emotions during trips and activity participation. The team used 2021 Daynamica survey data and 2019 Travel Behavior Inventory data from the Metropolitan Council to extract activity-travel patterns before and after COVID-19. The team associated these patterns with participants’ gender and other identities and SWB outcomes through visual explorations and statistical analysis. The findings suggested the importance of capturing the complex, intersectional nature of gender, confirmed the persistent existence of gender differences in transportation needs, experiences, and SWB outcomes in Minnesota, and supported continuous efforts and investments to advance gender equity in transportation.

This study investigates the perceived safety risks and barriers that might prevent transit and shared mobility services from attracting post-COVID riders in Greater Minnesota. It includes an online survey of Greater Minnesota residents to understand their COVID-related safety concerns and their preferences and perceptions toward existing and potential safety protocols. The survey results show that, during the post-COVID era, driving alone continues to dominate, but desires to use transit and shared mobility modes remain strong. Lack of access, lack of interest, and lack of available better alternatives jointly affect transit-use behavior. Women, people with COVID concerns, urban residents, online shoppers, and transit users are associated with stronger preferences toward COVID safety measures. People with COVID concerns, online shoppers, and transit users are also associated with preferences toward general transit service improvements. We also find that elderly people, hesitant tech users, and transit-dependent users are unlikely to be positively affected by trip-planning tools and contactless payment technology. Furthermore, income and car ownership predict future transit use, and younger age is associated with more interest in carpooling. These results help to inform transit and shared mobility providers about what safety and communications strategies will be most effective in bringing users back.

Transportation is a crucial contributor to health. It not only directly shapes the social and physical environments but also determines the type of places where people can live, learn, work, and play in their everyday lives. This project develops a conceptual framework for collaborative and equitable health and transportation planning by extending the social determinants of health framework to include three major pathways through which transportation factors operate on health and equity outcomes. The three major pathways are behavioral health, environmental health, and social exclusion, which are identified via a thorough review of the academic literature and gray resources on health and transportation connections. Of the three pathway mechanisms, social exclusion and environmental health are intrinsically linked to social equity and justice issues. We further review state-level initiatives linking transportation to health and interview six state departments of transportation that are pioneers in advocating and implementing integrated health and transportation planning. The interview results are summarized and discussed in the report. Based on the interviews, we make recommendations for the Minnesota Department of Transportation to help further its efforts on integrated health and transportation planning.

In 1992 the ABC Ramps were completed in downtown Minneapolis as part of the I-394 construction project. The purpose of the ramps is to have programs that support efforts to reduce congestion and improve air quality by reducing SOV trips from the I-394 corridor. At the time the ramps were built; the ramp goals were aligned with the city of Minneapolis' parking system goals and the I-394 Corridor Management Plan. Since that time; however; the transportation modes; technologies; and plans surrounding the ramps have changed as well as the travel behaviors of the users. As the ramps reach the midpoint of their design life; this study examined the programs; policies; and goals developed for the ramps to ensure they continue to address current transportation challenges and align with regional stakeholder's goals and emerging trends; behaviors; and technology. The project culminated in a series of recommendations with implementation strategies for the ABC ramp management to improve its practice towards reducing congestion and improving air quality in downtown Minneapolis through innovative programming and marketing.

After a long period of system deployment of the auto-highway system, and several decades of maturity of that system, the surface transportation sector is facing a large number of technological shifts that could change whether and how people travel. While nascent, their prospects are potentially significant. This research proposed to explore these technologies - ascertain their potential market, consider their interactions, understand what that might do to travel demands, and address how planning and forecasting should respond. This research developed a series of white papers: high-level policy briefs based on our analysis of each technology, its direction, and its implications for Minnesota. This work extends and complements the MnDOT 50 year vision expressed in Minnesota GO. It also builds on the ideas developed in the NCHRP 750 project: Strategic Issues Facing Transportation. The timeframe on these technologies varies, and the authors looked at deployment paths over time rather than simple snapshots in time.

Transitways represent large public investments whose positive impacts must be maximized whenever possible to justify the expenditures they entail. Prominent among those looked-for positive impacts is the encouragement of automobile-to-transit mode shifts by attracting increased transitway ridership. This study explores the impacts of travel time, travel cost, and population density on mode choice, using the 2010 Travel Behavior Inventory. We found a monetary value of in-vehicle travel time of $17.5/hour and a transfer penalty of $10, equivalent to 35 minutes in-vehicle travel time. Density, especially at destinations, has important effects, but travel time is the key to promote the shift to transit. The research also employs a Direct Ridership Model (DRM) to predict boardings at the station level as a function of transit-supportive policies. We find that station-area focused policies promoting affordable housing and sidewalks on all streets in station areas or entire cities have a significant and positive impact on ridership if there are sufficient potential destinations in the immediate station area, measured as the number of Google places within 100 meters. Based on our results, we stress the importance of station area affordable housing as a transit system efficiency measure, as well as for the social equity reasons it is usually encouraged. We recommend strengthening pro-affordable housing policies and pro-sidewalk policies in Twin Cities station areas, supporting and encouraging for the neighborhood-scale commercial development that is required for their efficacy, and the continued implementation of pro-affordable housing policies and pro-sidewalk policies as the regional transitway system expands.

Using detailed travel surveys (the Travel Behavior Inventory) conducted by the Metropolitan Council of the Minneapolis/Saint Paul (Twin Cities) Region in Minnesota for 1990, 2000-2001, and 2010-2011, this report conducts an analysis of changes in travel behavior over time. Specifically looking at changes in travel duration, time, use, and accessibility; telecommuting and its relationship with travel and residential choices; transit service quality and transit use; effects of age and cohort; and changes in walking and bicycling. Much has changed in this period, including the size of the region, demographics, economics, technology, driver licensing, and preferences, examining in turn the effects of investment, development, and population change on behaviors for the Minneapolis-St. Paul region as a whole and for areas within the region. While this research cannot hope to untangle all of the contributing factors, it aims to increase understanding of what did happen, with some explanation of why. This will inform transportation engineers, planners, economists, analysts, and decision makers about the prospective effects of future changes to networks, land use, and demographics while also evaluating the effects of previous network investments.
