Advancing Equity in Accessibility and Travel Experiences: The Role of Gender and Identity

(c)1036342 (wo) 25Gender can have a significant influence on people\u2019s 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\u2019s 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\u2019 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\u2019 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

Cost Estimate of B vs. C Grade Asphalt Binders

(c) 1036342 (wo) 20Polymer-modified binders (PMB) have been shown over the decades to improve the mechanical properties of asphalt mixtures compared to unmodified binders. Considering the higher initial cost of PMB, selecting the best alternative is very important, especially for local agencies given their limited budgets. A challenge in the materials selection process for low-volume roads is the limited information available, which could allow engineers to determine whether using PMB is cost-effective. In this research, we investigate the use of PG 58H-34 PMB binders (grade C) and PG58S-28 unmodified binders (grade B) for low-volume roads in Minnesota. Historical pavement performance data are analyzed to compare the field performance of modified and unmodified mixtures. Laboratory experiments are performed to compare the low-temperature cracking properties of polymer-modified and unmodified binders and mixtures commonly used in Minnesota. Based on the experimental results, a life-cycle cost analysis (LCCA) is performed comparing the use of polymer-modified and unmodified binders for low-volume roads in Minnesota. The results show that using PMBs for new construction is expected to extend the pavement service life by 6 years, and that usin

Racial and Gender Diversity in State DOTs and Transit Agencies

This publication documents and analyzes racial and gender diversity in state departments of transportation (state DOTs) and transit agencies for purposes of establishing a baseline that reflects the current status of racial and gender diversity in state DOTs and transit agencies based on existing data. This report will be useful to Chief Administrative Officers of state DOTs, Chief Executive Officers of transit agencies, state DOT officials, transit officials, and other transportation professionals interested in workforce development
