Curb space has been traditionally designed for private vehicle parking, public transit, and passenger and commercial loading. However, in recent years, a growing number of newservices and activities have increased the demand for limited curb space, including passenger pick-up and drop-off; last-mile delivery (e.g., courier network services, personal delivery devices); electric vehicle (EV) charging; micromobility parking and use (e.g., personally owned and shared bikes and scooters); and carsharing services. The curb serves a variety of functions such as vehicle and device storage (...

Generic Time- and Method-Interdependencies of Empirical Impact-Measurements: A Generalizable Model of Adaptation-Processes of Carsharing-Users' Mobility-Behavior Over Time

Firnkorn, Jörg
Shaheen, Susan, PhD
2016

The purpose of this article is to advance empirical sustainability-evaluations of carsharing-systems. Carsharing, a frequently cited example of a product–service system (PSS), is currently morphing from a niche into a mainstream mode of transportation. Carsharing has the potential to provide a more sustainable mobility-option compared to private car usage, for example by reducing the overall motor-vehicle traffic in cities. However, the quantification of this potential is complex, and few studies have analyzed the fundamental impacts of the chosen measurement-methodology on the results of...

Shared Mobility: A Sustainability & Technologies Workshop: Definitions, Industry Developments, and Early Understanding

Shared mobility - the shared use of a vehicle, bicycle, or other mode - enables users to gain short-term access to transportation modes on an “as-needed” basis. Shared mobility includes carsharing, bikesharing, ridesharing, and on-demand ride services. It can also include alternative transit services, such as paratransit, shuttles, and private transit services. Smartphone “apps” are available to aggregate options and optimize routes. New ways of transporting and delivering goods also have emerged with the potential to change the nature of the package and food delivery industry. Shared...

Mobility on Demand (MOD) Demonstration: Chicago Transit Authority (CTA) Ventra-Divvy Integration Case Study

Cohen, Adam

Martin, Elliot
2021

The Federal Transit Administration’s (FTA) Mobility on Demand (MOD) Sandbox Program provides a venue through which integrated MOD concepts and strategies, supported through local partnerships, are demonstrated in real-world settings. This case study documents lessons learned from the Chicago Transit Authority (CTA) MOD Sandbox Demonstration, called Ventra–Divvy Integration. The case study is a part of an independent evaluation of the MOD Sandbox Demonstrations sponsored by the USDOT Intelligent Transportation Systems Joint Program Office (ITS JPO) and FTA. The case study includes...

One-Way Electric Vehicle Carsharing in San Diego: An Exploration of the Behavioral Impacts of Pricing Incentives on Operational Efficiency

Shaheen, Susan, PhD
Martin, Elliot, PhD
Bansal, Apaar
2018

This project is a two-year evaluation of pricing/incentives applied to the one-way, all electric carsharing system operated by car2go in San Diego, CA. This system is the only electric vehicle-based, one-way carsharing system with instant access (i.e., accessible without reservation) operating in the U.S. The goal of this project is to work with car2go and the San Diego region to develop and evaluate pricing/incentive structures for their members, which improve system operational efficiency (vehicle redistribution, state-of-charge management, use of vehicles placed at public transit...

Automated Vehicles, On-Demand Mobility and Environmental Impacts

Greenblatt, Jeffery
Shaheen, Susan, PhD
2015

We review the history, current developments, projected future trends and environmental impacts of automated vehicles (AVs) and on-demand mobility, and explore potential synergies. Many automobile manufacturers and Google plan to release AVs between 2017 and 2020, with potential benefits including increased safety, more efficient road use, increased driver productivity and energy savings. Estimates of AV energy use and greenhouse gas (GHG) emissions range from an ~80 % or greater decrease to a threefold increase; however, we argue that net decreases are likely. On-demand mobility services...

Mobility on Demand (MOD) Sandbox Demonstration: Bay Area Rapid Transit Integrated Carpool to Transit Access Program Evaluation Report

2020

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...

Public Bikesharing in North America: Early Operator Understanding and Emerging Trends

Shaheen, Susan, PhD
Cohen, Adam
Martin, Elliot, PhD
2013

Public bikesharing—the shared use of a bicycle fleet by the public—is an innovative mobility strategy that has recently emerged in major North American cities. Bikesharing systems typically position bicycles throughout an urban environment, among a network of docking stations, for immediate access. Approximately five years ago, information technology (or IT)-based bikesharing services began to emerge in North America. Between 2007 and March 2013, 28 IT-based programs have been deployed–24 are operational, two are temporarily suspended, and two are now defunct in the United States (U.S.)...
