The General Transit Feed Specification Makes Trip-Planning Easier – Especially During a Pandemic – Yet its Use by California Agencies is Uneven

Abstract

Developed in 2005, the General Transit Feed Specification (GTFS) is making transit trip planning easier by allowing public transportation agencies to share transit schedules in an electronic format that can be used by a variety of trip-planning applications, such as Google Maps. The GTFS can be used to share static transit schedules (GTFS-s) or provide real-time information on transit vehicle arrivals and departures (GTFS-r). Providing real-time updates has proven to be exceptionally valuable during the COVID-19 pandemic. For example, between January 13th and April 25th of this year Apple estimates that transit use in the United States decreased by 75%1 , which caused many public transit providers to modify their services. The California Integrated Travel Project (CITP) recently called for widespread adoption of GTFS-s and GTFS-r2 ; however, little is known about GTFS use across agencies and, in turn, the barriers to widespread adoption.

Synthesis of State-level Planning and Strategic Actions on Automated Vehicles: Lessons and Policy Guidance for California

Abstract

This synthesis provides a summary and comparative analysis of actions states across the United States are taking in response to automated vehicles (AVs). The research focuses on state-level stakeholder forums (e.g., task forces, committees) and state-level strategic actions (e.g., studies, initiatives, programs) initiated by a state legislature, governor, or state agency. The analysis found that automated vehicle stakeholder forums and strategic actions address a diverse set of focus areas, but they pay minimal attention to the implications of automated vehicles on the environment, public health, social equity, land use, public transit, goods movement, and emergency response. Also, forums and strategic actions commonly include members from state transportation departments, the legislature, and academia; however, representatives from industry and non-governmental organizations (NGOs) are included less often. Academia and researchers participate in the majority of automated vehicle forums and actions, either in an advisory capacity (i.e., sharing expertise and experience) and/or through conducting research. Based on this analysis, the synthesis concludes with a recommendation for California to form a state-level working group representing leaders from the public sector, industry, non-governmental organizations, and academia to advise the Governor and the Legislature on automated vehicle policy across a range of focus areas.

Estimating the Pollution Abatement Potential of Electric Vehicle Subsidies

Abstract

The true net environmental benefit of an electric vehicle is relative to the vehicle that an electric vehicle buyer would have bought and driven had they not opted for an electric vehicle. This “counterfactual” vehicle cannot be observed, but its fuel economy can be estimated. We use a quasi-experimental variation in a generous California electric vehicle subsidy program to show that buyers of electric vehicles would have, on average, purchased fuel-efficient gasoline-powered cars had they not gone electric.
