Carsharing is a service in which individuals gain the benefits of private vehicle use without the costs and responsibilities of ownership. Individuals typically access vehicles by joining an organization that maintains a fleet of cars and light trucks. Fleets are usually deployed within neighborhoods and at public transit stations, employment centers, and colleges and universities. Typically, the carsharing operator provides gasoline, parking, and maintenance. Generally, participants pay a fee each time they use a vehicle (Shaheen, Cohen, Zohdy, 2016). Carsharing includes three types of...

Shared Mobility Policy Playbook - Microtransit | 1Microtransit is a privately or publicly operated, technology-enabled transport service that typically uses multi-passenger/pooled shuttles or vans to provide on-demand or fixed-schedule services with either dynamic or fixed routing (Cohen & Shaheen, 2016; SAE International, 2018. This tool kit identifies potential use cases for microtransit and provides case studies of pilot programs, public-private partnerships, and permit programs for private operators. The tool kit concludes with a summary of opportunities and challenges for...

Ridesharing (Carpooling and Vanpooling)

Ridesharing allows travelers to share a ride to a common destination and can include several forms (Shaheen & Cohen, 2019; Chan & Shaheen, 2011; SAE International, 2018). Ridesharing differs from for-hire vehicle services (i.e., transportation network companies (TNCs), ridesourcing, and ridehailing) in its financial motivation. When a ridesharing payment is collected, it partially covers the driver’s cost and is not intended to result in financial gain. Additionally, the driver has a common origin and/or destination with the passengers. In this toolkit, readers will find a summary...

Social Equity Impacts of Congestion Management Strategies

2019

This white paper examines the social equity impacts of various congestion management strategies. The paper includes a comprehensive list of 30 congestion management strategies and a discussion of equity implications related to each strategy. The authors analyze existing literature and incorporate findings from 12 expert interviews from academic, non-governmental organization (NGO), public, and private sector respondents to strengthen results and fill gaps in understanding. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework (...

Zero-Emission Vehicle Exposure Within U.S. Carsharing Fleets and Impacts on Sentiment Toward Electric-Drive Vehicles

Reducing carbon emissions from the United States (U.S.) transportation sector has emerged as a priority action to combat climate change. Carsharing and zero-emission vehicles (ZEVs) could be integral to creating a more sustainable transportation system. This paper presents the results of a study that evaluated the impacts of ZEV exposure on U.S. carsharing users. Surveys were administered to control and experimental groups of carsharing members that used shared PHEVs or EVs. Results showed that users who drove shared PHEVs or EVs more frequently were more likely to exhibit improved ZEV...

Shared mobility can include roundtrip services (a vehicle, bicycle, scooter, or other mode is returned to its origin); one-way station-based services (a vehicle, bicycle, scooter, or other mode is returned to a different designated station location); and one-way free-floating services (a vehicle, bicycle, scooter, or other mode can be returned anywhere within a geographic area). To help manage free-floating services, cities and shared mobility operators may use technologies like geofencing. Geofencing is a technology that uses GPS or RFID technology to create a virtual boundary, enabling...

The Mobility on Demand (MOD) Sandbox Demonstration Program provides a venue through which integrated MOD concepts and solutions, supported through local partnerships, are demonstrated in real-world settings. For each of the 11 MOD Sandbox Demonstration projects, a MOD Sandbox Independent Evaluation was conducted that includes an analysis of project impacts from performance measures provided by the project partners and an assessment of the business models used. This document presents the Evaluation Report for the BART Integrated Carpool to Transit Access Program project. The project tested...

Review of California Wildfire Evacuations from 2017 to 2019

2020

Between 2017 and 2019, California experienced a series of devastating wildfires that together led over one million people to be ordered to evacuate. Due to the speed of many of these wildfires, residents across California found themselves in challenging evacuation situations, often at night and with little time to escape. These evacuations placed considerable stress on public resources and infrastructure for both transportation and sheltering. In the face of these clear challenges, transportation and emergency management agencies across California have widely varying levels of preparedness...

This report provides Mobility on Demand (MOD) planning and implementation practices and tools to support communities. The report discusses different stakeholders in the MOD ecosystem and the role of partnerships in filling spatial, temporal, and other service gaps. Additionally, the report discusses how MOD can be integrated into transportation planning and modeling. The report also discusses shared mobility implementation considerations, such as rights-of-way management, multimodal integration, data sharing, equity, labor impacts, and the role of pilot evaluations. Finally, the report...

Fleeing from Hurricane Irma: Empirical Analysis of Evacuation Behavior Using Discrete Choice Theory

This paper analyzes the observed decision-making behavior of a sample of individuals impacted by Hurricane Irmain2017(n = 645) by applying advanced methods based in discrete choice theory. Our first contribution is identifyingpopulation segments with distinct behavior by constructinga latent class choice model for the choice whether to evacuate or not. We find two latent segments distinguished by demographics and risk perception that tend to be either evacuation-keen or evacuation-reluctant and respond differently to mandatory evacuation orders.Evacuees subsequently face a multi-...
