The post-pandemic "new normal" is characterized by increased adoption of telework and a decline in transit use, with a growing uncertainty about the long-term effects of these trends. This study investigates the impact of telework adoption on commute mode choice and the factors influencing individual preferences in the new normal, using data from the 2022 Seattle Commute Survey, capturing mode choice on each day in a typical workweek, providing a mixture of modes and the frequency of use for each respondent. Using the Multiple Discrete-Continuous Extreme Value (MDCEV), the study provides timely insights into the factors influencing commute mode choice, highlighting the significant influence of sociodemographic, job-related, and built environment characteristics on mode choice and the nuanced difference between modes, raising concerns about potential inequities in the new normal. The findings highlight the need to prioritize access to public transit, adapt transportation infrastructure to telework, and address rising inequities.

Transit Incorporating Mobility-on-Demand (TIMOD) represents the public-private partnerships in which transit agencies incorporate MOD services to supplement fixed-route transit. This study evaluates the cost-effectiveness of TIMOD compared to buses, driving, and ride-hailing in suburban settings. For each alternative, it estimates the marginal costs for travelers, service providers, and transportation externalities, which constitute the marginal social cost. In the study cases, TIMOD is the least cost-effective option, with marginal social cost approximately 20% higher than TNCs and over three times higher than driving. For travelers, TIMOD costs more than driving but less than buses and ride-hailing when considering time value and fare. The cost of TIMOD declines as population density increases. Suburbs with less bus services and higher income residents benefit more from TIMOD, realizing greater reductions in time costs compared to buses. Transit agencies should explore alternative ways to improve mobility for disadvantaged suburban residents by offsetting driving costs and subsidizing TNCs fares.

Public transit services, which provide a critical lifeline for many essential workers, were severely interrupted during the COVID-19 pandemic. As institutions gradually return to normal in-person operations, it is critical to understand how the pandemic affected essential workers' commute and what it will take to ensure the effective recovery of transit ridership and enhance the long-term resiliency and equity of public transportation systems for those who need it the most. This study used focus group discussions with essential workers who were pre-pandemic transit riders to understand how the COVID-19 pandemic has impacted their commute perceptions, experiences, motives, and challenges and explore the potential changes in their travel behavior post-pandemic. We used NVivo 12 Pro to conduct a thematic analysis of the transcripted discussion data and examined patterns of commute mode change with respect to participants' attributes, including job type, home location, and gender. The results show that public transit had multiple reliability and frequency challenges during the pandemic, which resulted in most participants switching away from public transportation. With the increased availability of hybrid remote work and pandemic-related parking policies, driving emerged as a safer and more affordable commute mode for many pre-pandemic transit riders, rendering transit services less efficient for those who continued to rely on it. Planning for post-COVID resilient and reliable mobility requires a major rethinking of providing an efficient and effective transport system and a more fundamental approach to long-term public transport policy. To recover transit ridership, transit agencies need to ensure transit service availability and provide reliable transit information through smartphone apps. Similarly, transit agencies need to coordinate with other employers to provide free or heavily subsidized transit passes, to facilitate the recovery of transit demand effectively.

During disruptive events and major crises such as the COVID-19 pandemic, essential workers, defined in this study as employees who must continue to make frequent commute trips, play a critical role in maintaining the basic function of society. It is therefore vital for transportation planners and policymakers to ensure that adequate mobility services are provided to meet the travel needs of this group of workers. To better understand essential workers' mobility barriers and inform future transportation policy, this research examines their pre- and during-pandemic commutes, as well as prospects on future commuting, using data from the Transportation Needs Assessment Survey conducted by the University of Washington in Seattle. The results show that, first, over 60% of pre-pandemic public transit riders switched to other modes, especially driving alone. In contrast, almost all the essential workers who drove alone, biked, or walked before the pandemic continued to do so during the pandemic. Second, the shift to driving alone was most pronounced among essential workers with high incomes, whereas public transit remained as a primary mode choice of lower-income groups. As travel distance increased, the probability of driving alone over public transit also went up, although the relationship was not linear. We did not find consistently significant associations between mode choice and other sociodemographic variables. Finally, our analysis indicated that most essential workers anticipated to return to their pre-pandemic commute frequency and mode choice when the pandemic is under control. Transportation planners and policymakers can facilitate mobility for essential workers through planning and policy innovations, especially during disruptive events and major crises.

Paratransit services developed under the Americans with Disabilities Act are a critical transportation means for persons with disabilities to meet their basic needs, but the COVID-19 pandemic posed an unprecedented challenge to service providers. To safeguard transportation equity, this study used complete records of service trips and riders obtained from the Access Transportation Program in the Seattle region for an empirical analysis aimed at answering two research questions. First, how did the ridership and trip purposes of paratransit change after the outbreak of COVID-19? Second, what factors explained the users' changing levels of service usage in response to the pandemic? Statistical methods, including a Hurdle model, were employed as the analytical tools. The results show that paratransit ridership dramatically decreased during 2020 with the most substantial reductions of working and non-essential personal trips, and that most of the remaining trips were for medical purposes. The results also indicate that riders' service usage during the pandemic was associated with their sociodemographic characteristics, disability conditions, and pre-pandemic travel demand. When controlling for other factors, riders who lived in neighborhoods with lower income and lower access to personal vehicles were more dependent on the service. Based on the empirical findings, we recommend that when developing plans for future disruptive events, public transit agencies should promptly implement safety measures, identify and prioritize neighborhoods that are most in need of mobility services, and actively pursue collaboration with other organizations for innovative service delivery options.

The Americans with Disabilities Act (ADA) requires public transit agencies to provide an equivalent transportation service for people with disabilities, known as ADA paratransit service. As the U.S. population continues to grow and age, the demand for paratransit service keeps rising, posing many challenges for transit agencies due to its high operational cost. In response, a growing number of transit agencies are looking to incorporate alternative paratransit services by forming partnerships with transportation network companies (TNCs) to provide what is known as same-day service (SDS). However, most of these partnerships are still in the pilot phase, and scant research investigates the opportunities and barriers of SDS or provides guidelines and measures for transit agencies interested in such partnerships. Considering both the characteristics of paratransit trips and riders and the operational norms of TNCs, this paper explores different conditions under which SDS trips are most appropriate and estimates potential trip diversion from conventional paratransit to SDS operated by TNCs. Trip diversion conditions include (1) trip length, which is impacted by the subsidy amount for SDS and the dynamic pricing of TNC trips, (2) level of service, which depends on the level of mobility assistance required by paratransit riders, and (3) the operational efficiency of conventional paratransit. Different settings and combinations of these conditions help transit agencies explore the potential trip diversion of SDS while considering significant barriers to the service. Using 2019 ridership data of Access paratransit, the ADA paratransit services in the Seattle region, this research finds that without an excessive subsidy amount, transit agencies can divert up to 18% of paratransit trips to SDS. This percentage can drop to as low as 11% of paratransit trips if transit agencies further limit the SDS service area to ensure the efficiency of conventional ADA paratransit. This paper concludes that although SDS provides many benefits, significant barriers inherent to TNC business models and paratransit users should be carefully examined when pursuing ADA paratransit-TNC partnerships.

INTRODUCTION:Along with all public transit services, paratransit services for people with disabilities experienced substantially reduced demand and an increased need to provide equitable services while protecting their clients and staff's safety during the COVID-19 pandemic. Paratransit services provide a lifeline for their clients' essential mobility needs, including access to medical appointments and grocery stores. In the absence of pre-existing pandemic response plans, examining transit agencies' responses to provide paratransit services during the pandemic can help inform planning for post-pandemic recovery and future disruptive events.METHODS:In September 2020, we conducted semi-structured interviews with 15 decision-makers, planners, and drivers working for the primary transit agency in the Seattle region - King County Metro - and its paratransit contractors. Interview questions were designed to identify current services, policy gaps, and critical challenges for recovery planning and post-pandemic paratransit services. Interview transcripts were analyzed using NVivo software to obtain essential themes.RESULTS:The interviewees provided insights about (1) paratransit service changes in response to the pandemic, (2) anticipated impacts of a returning demand on paratransit service efficiency, equity, and quality during the recovery period, and (3) innovative approaches for maintaining post-pandemic equitable paratransit services while balancing safety measures with available resources.CONCLUSIONS:Study findings suggest that paratransit service providers should consider (1) developing guidelines for future disruptive events, (2) examining alternative methods for food delivery to clients, (3) planning scenarios for delivering equitable services in the post-pandemic recovery period, and (4) increasing resilience possibly by establishing partnerships with transportation network companies.
