Project Summary

Microtransit offers an alternative approach to public transportation, and California's public transit agencies have embraced it to address specific challenges. Typically, government entities or nonprofits operate these services, although private microtransit programs also exist. Public transit agencies and municipalities across California have implemented, tested, and/or considered microtransit services. The degree of success in these endeavors varies based on the specific goals and metrics they assess. However, there is a research gap in understanding how to effectively scale microtransit across different regions in California. This entails optimizing transit services for efficiency, improving social equity, enhancing job access, and appropriately tailoring resources. Additionally, apart from identifying and evaluating microtransit systems in various scenarios, it's crucial to define and measure what constitutes success. This includes considering factors like cost and time savings, shifts in travel behavior, changes in vehicle miles traveled, and their impact on vehicle ownership, among other aspects. This project will investigate microtransit usage patterns among individuals, delving into who utilizes this service, for what types of trips, and whether it leads to changes in transportation choices. Additionally, the study will utilize simulation models to assess how different service configurations (such as the number of vehicles and route options) impact various outcomes, such as passenger service quality (including wait times and detour times), service equity, and overall costs. Furthermore, the research will evaluate these outcomes in relation to different levels of fixed-route transit. Throughout the project, the team will collaborate with transit agencies and other entities involved in providing microtransit services for each case study. The goal is to identify and refine performance metrics, taking into account the diverse service models and geographic contexts of these cases. The project involves three distinct, Via-supported microtransit case studies, each in different land use and built environments. These locations span the Central Valley and East and South Bay regions and feature different service models, including blended approaches like paratransit and integrated overall mobility solutions.

Project Summary

California has set ambitious goals to transition all drayage trucks to zero-emission vehicles (ZEVs) by 2035 and, where feasible, transition the remaining medium- and heavy-duty vehicles (M/HDVs) to ZEVs by 2045. However, ZEV adoption in the M/HDV sector has been slow, primarily due to significant challenges faced by fleet operators. These challenges include the high initial expenses associated with vehicle acquisition and the construction of fueling/charging infrastructure. They also involve the complexities of infrastructure installation and maintenance, along with concerns about the operational and financial risks linked to ZEVs. These barriers can be particularly acute for specific fleet segments, notably those with limited physical space for charging/fueling facilities or those characterized by lower risk tolerance, a common trait among smaller fleets and owner-operators. To address these barriers effectively, it is necessary to explore innovative solutions for ZEV procurement, beyond conventional buying or leasing methods. Accordingly, the Innovative Small e-Fleet Program by the California Air Resources Board (CARB) supports such solutions, including flexible leases, short-term rentals, Truck-as-a-Service (TaaS), and other mechanisms. TaaS is an application of a “servitized” business model where customers pay for the service on a per-use basis, encompassing both the usage of trucks and the associated fueling/charging. The servitized model has the potential to reduce the total cost of ownership; however, the implications of TaaS on the transition to zero-emission M/HDVs is unknown. This research aims to comprehensively assess the role of TaaS in California’s ZEV transition from various perspectives. By enhancing an existing tool created by the research team in a previous project and by leveraging fleet survey and interview data from ongoing projects, this project will explore diverse TaaS offerings. The researchers will assess their cost-effectiveness across fleet segments and analyze long-term implications on the overall fleet transition. Equity and job considerations will also be addressed as well, with a focus on equity issues for disadvantaged fleets and implications for job creation and worker training. The research findings will fill a knowledge gap and generate practical insights for promoting ZEV adoption through innovative solutions.
