Social Mobility Sharing

Traffic congestion, dominated by single-occupancy vehicles, reflects not only transportation system inefficiency and externality, but also a sociological state of human isolation. Advances in information and communications technology are enabling the growth of real-time ride sharing to improve system efficiency. Lesser understood, however, are the expectation and experience of social interactions and social prejudice during ride sharing. JTL investigates the nature of shared rides: impromptu, captive for a considerable duration, and even intimate in a confined space, particularly its unique juxtaposition of spontaneity and intensity; develops human-centric ride sharing systems that respect both network efficiency and individuals’ preferences (or lack of) for human interaction; and explore the opportunities of shared mobility as a tool to foster and strengthen human interactions.

Perspectives on the Ridesourcing Revolution : surveying individual attitudes toward Uber and Lyft to inform urban transportation policymaking, Dawes, Margo , Department of Urban Studies and Planning, Volume MCP, Cambridge, MA, (2016)

Media coverage of ridesourcing services such as Uber and Lyft has described a rivalry between new technology and the established taxi industry. Individual users and non-users of ridesourcing, however, may have more nuanced perspectives, but policymakers have little guidance on how to best represent these interests. This thesis uses a standardized questionnaire distributed across the United States by an online survey company to understand individual attitudes toward Uber, Lyft, and...

The Tradeoff Between Efficiency and Fellow Passenger Preference: a Preference-Based Ridesharing Model, Zhang, Hongmou, and Zhao Jinhua , Transportation Research Board 96th Annual Conference, Washington, D.C., (2017)

Advances in information technology are enabling the growth of real-time ridesharing—whereby passengers are paired up on car trips to improve system efficiency by using fewer cars. Lesser known, however, are the opportunities of shared mobility as a tool to foster and strengthen human interactions. The nature of shared car rides is impromptu, captive for a considerable duration, and remarkably more intimate, representing a unique juxtaposition of spontaneity and intensity. While ridesharing...

To Share or Not to Share: Investigating the Social Aspects of Dynamic Ridesharing, Morales-Sarriera, Javier, lvarez German Escovar Á., Blynn Kelly, Aylesbury Andrew, Scully Tim, and Zhao Jinhua , Transportation Research Record: Journal of the Transportation Research Board, (2017)

Transportation Network Companies (TNCs) have recently introduced shared ride versions of their ordinary services, such as UberPool or Lyft Line, in a number of cities around the world. At base, the concept is simple: passengers pay less in fares for an incremental increase in time spent picking up and dropping off other riders. Time and cost trade-offs related to mode choice in transportation have been studied extensively; however, the social and behavioral considerations of shared rides...

User Identification of and Attitude Toward Dynamic Ridesourcing Services, Dawes, Margo, and Zhao Jinhua , Transportation Research Board 96th Annual Conference, Washington, D.C., (2017)

Media coverage of ridesourcing services such as Uber and Lyft has described a rivalry between new technology and the established taxi industry. Individual users and non-users of ridesourcing may have more nuanced perspectives, but policymakers have had little guidance on how to best represent these interests.

Social Mobility Sharing: Faceless Efficiency or Emerging Mode of Human Interaction, Zhang, Hongmou, Rosenfield Adam, and Zhao Jinhua , (2017)

Traffic congestion, dominated by single-occupancy vehicles, reflects not only transportation system inefficiency and externality, but also a sociological state of human isolation. Advances in ICT are enabling the growth of real-time ride sharing—whereby passengers are paired up on car trips with similar Origin-Destinations and proximate time windows—to improve system efficiency by moving more people in fewer cars. Lesser known, however, are the opportunities of shared mobility as a tool to...

Abstract 


Regulating Social Prejudice in Shared Mobility (proposal), Middleton, Scott , (0)

This research proposes to answer three questions related to discrimination among drivers, passengers, and co-passengers in the ridesharing industry. The first question asks to what extent ridesharing exacerbates or facilitates pre-existing social prejudice, according to the literature on discrimination and ridesharing. The second question considers appropriate strategies for reducing discriminatory behavior through policy and system design. To answer this question, this research will compile...

Humanizing Travel: How E-hail Apps Transform Stakeholder Relationships in Taxi Services, Li, Corinna, and Zhao Jinhua , Transportation Research Board 94th Annual Meeting, Washington, D.C., (2015)

Efficiency benefits of the increasingly popular taxi-hailing (e-hailing) apps have been widely discussed - reduction of search time, convenience for passengers, and higher income for drivers. However the project proposes that there is a qualitative difference that e-hailing apps are engendering in the United States (U.S.) taxi industry above and beyond their quantitative impacts. E-hailing establishes direct connections between drivers and passengers, making ride requests person-to-person...

Behavior and Policy: Connection in Transportation

This course examines the behavioral foundation for policy design, using urban transportation as examples. We introduce multiple frameworks of understanding travel behavior, rational or irrational, contrasting the perspectives of classic economic theory with behavioral economics and social psychology, and suggest corresponding policy interventions: a behavior--theory--policy mapping. Then we present a spectrum of ten instruments for positively influencing behavior and improving welfare: from...
