In recent years, innovative mobility and shifts in travel and consumption behavior are changing how people access and use the curb. Shared mobility—the shared use of a vehicle, bicycle, scooter, or other mode—coupled with outdoor dining, curbside pick-up, and robotic delivery are creating new needs related to the planning, management, and enforcement of curb access. This study examines curb planning and management from several angles, such as safety, social equity, and multimodal connections. This research employs a multi-method approach to identify the changing needs for curb space...

Shared Micromobility: Policy and Practices in the United States

2021

Shared Micromobility - the shared use of a bicycle, scooter, or other low-speed mode - is an innovative transportation strategy that enables users short-term access to a transportation mode on an as-needed basis. Shared micromobility includes various service models and transportation modes that can meet diverse traveler needs, such as station-based bikesharing (a bicycle picked-up from and returned to any station or kiosk) and dockless bikesharing and scooter sharing (a bicycle or scooter picked up and returned to any location). Shared micromobility has the potential to offer communities...

Local Government Strategies to Improve Shared Micromobility Infrastructure

Shared micromobility (bikesharing and scooter sharing) experienced market growth since 2021, rebounding from the pandemic across markets in the US, Mexico, and Canada. In partnership with the North American Bikeshare and Scootershare Association (NABSA) and Toole Design, researchers at the Transportation Sustainability Research Center (TSRC) at UC Berkeley have collaborated on the data collection and analysis of the shared micromobility industry metrics through a series of annual reports beginning in 2019. This includes a series of operator and agency surveys.1 Most recently, TSRC...

Lead with the Helmet

Bikesharing systems offer access to a shared network of bicycles deployed on public streets. Present-day systems use information technology to manage user interactions, and to manage the fleet of bicycles. Bikesharing systems can be station-based, in which users access bicycles at kiosks with automatic locks, or free-floating, in which self-locking bicycles are accessed within a geo-fenced area. Bikesharing generally permits point-to-point travel, providing users with flexibility to use the service as a first-mile/last-mile connection or as its own means from origin to destination....

Bikesharing and Bicycle Safety

The growth of bikesharing in the United States has had a transformative impact on urban transportation. Major cities have established large bikesharing systems, including Boston, Chicago, Denver, Minneapolis-Saint Paul, New York City, Salt Lake City, the San Francisco Bay Area, Seattle, Washington DC, and others. These systems began operating as early as 2010, and no fatalities have occurred within the US as of this writing. However, three have happened in North America—two in Canada and one in Mexico. Bikesharing has some qualities that appear inherently unsafe for bicyclists. Most...

Public Bikesharing in North America During a Period of Rapid Expansion: Understanding Business Models, Industry Trends & User Impacts, MTI Report 12-29

Public bikesharing—the shared use of a bicycle fleet—is an innovative transportation strategy that has recently emerged in major cities around the world, including North America. Information technology (IT)-based bikesharing systems typically position bicycles throughout an urban environment, among a network of docking stations, for immediate access. Trips can be one-way, round-trip, or both, depending on the operator. Bikesharing can serve as a first-and-last mile connector to other modes, as well as for both short and long distance destinations. In 2012, 22 IT-based public...

Public Bikesharing In North America : Early Operator and User Understanding [research brief].

Public bikesharing—the shared use of a bicycle fleet—is an innovative transportation strategy that has recently emerged in North America. Bikesharing systems typically position bicycles at docking stations for immediate access. Trips can be one-way or round-trip. As of January 2012, 15 information technology (IT)-based, public bikesharing systems had emerged in the United States—accounting for 172,070 users and 5,238 bicycles, and four IT-based programs accounted for 44,352 users and 6,235 bicycles in Canada. This study documents the state of public bikesharing in the U.S. and Canada and...

What Should Agencies Measure to Decide If Microtransit Is Working?

2026

California state agencies, public transit agencies, and cities have invested in dozens of microtransit pilot programs, often with the stated goals of improving access, filling gaps in fixed-route public transit service, and serving communities that are difficult to reach by traditional bus or rail. As microtransit services mature, agencies increasingly face decisions about whether to expand, modify, or discontinue microtransit services—and how to allocate scarce operating funds across competing transit priorities.

UAV Scheduling Strategies in Multi-modal Last-Mile Urban Parcel Delivery

2023

Urban parcel delivery has emerged as a high growth market, and the resulting delivery traffic can pose great challenges in dense urban areas. There is growing interest in supplanting the conventional model of a dedicated delivery person operating a van to alternatives featuring new classes of vehicles such as drones, autonomous ground vehicles, cargo bikes and non-motorized vehicles. This work proposes combined delivery strategies using trucks, cargo bikes and drones. We develop and compare multi-modal delivery strategies with various mode combinations. We work on zone-based multi-modal...

Pilot Models for Estimating Bicycle Intersection Volumes

Schneider, Robert J.
2011

Bicycle volume data are useful to practitioners and researchers to understand safety, travel behavior, and development impacts. This paper describes the methodology used to develop several simple models of bicycle intersection volumes in Alameda County, California. The models are based on two-hour bicycle counts performed at a sample of 81 intersections in the Spring of 2008 and 2009. Study sites represented areas with a wide range of population density, employment density, proximity to commercial property, neighborhood income, and street network characteristics. The explanatory variables...
