Going My Way? The Evolution of Shared Ride and Pooling Services

May 29, 2020

man driving vehicle

Sharing rides is a longstanding tradition that predates even horse-and-buggy travel. Recent innovations, however, make sharing a ride easier, more convenient, and more efficient. Innovative mobility services premised on pooling — getting multiple riders into the same vehicle — can lower travel costs, mitigate congestion, and reduce greenhouse gas emissions. They also offer travelers more mobility choices...

Chapter 13 - Sharing strategies: carsharing, shared micromobility (bikesharing and scooter sharing), transportation network companies, microtransit, and other innovative mobility modes

2020

Shared mobility—the shared use of a vehicle, bicycle, or other mode—is an innovative transportation strategy that enables users to gain short-term access to transportation modes on an “as-needed” basis. It includes various forms of carsharing, bikesharing, scooter sharing, ridesharing (carpooling and vanpooling), transportation network companies (TNCs), and microtransit. Included in this ecosystem are smartphone “apps” that aggregate and optimize these mobility options, as well as “courier network services” that provide last mile package and food delivery. This chapter describes...

Lyft CEO Juggles Growth Ambitions With Social Ideals

March 7, 2019

As an environmentally minded college student in California, Logan Green led a campaign to raise campus parking rates to discourage driving. Some 15 years later, as CEO of Lyft, Mr. Green has continued to promote the idea of reducing automobile ownership. “It’s time to redesign our cities around people, not cars,” he and Lyft co-founder John Zimmer wrote in a letter to investors unveiling the company’s IPO plans.

Casual carpooling is an informal form of commuter ridesharing operating in Washington, D.C.; Houston, Texas; and San Francisco, California. In contrast to new forms of shared-use mobility, casual carpooling has been in existence for over 30 years and uses no information communication technology, and is entirely run informally by its users. Researchers have been fascinated by this phenomenon and have conducted studies in the past, but there remains a lack of up-to-date quantitative data. This study examines the motivations and behaviors of casual carpoolers in the San Francisco Bay Area to...

Carpooling allows travelers to share a ride to a common destination and can include several forms of sharing a ride, such as casual carpooling and real-time carpooling. Because carpooling reduces the number of automobiles needed by travelers, it is often associated with numerous societal benefitsincluding: 1) reductions in energy consumption and emissions, 2) congestion mitigation, and 3) reduced parking infrastructure demand. In recent years, economic, environmental, and social forces coupled with technological innovations are encouraging shared and pooled services. Shared mobility is...

Uber and Lyft are driving toward IPOs

October 18, 2018

Uber and Lyft already compete in ride-hailing, ride-sharing, bike-sharing and e-scooters. Next year, they'll be competing for investors, too: Both companies are reportedly planning initial public offerings for early 2019.

For years, the companies have subsidized rides to keep costs low for customers. That fueled their growth, which in turn pumped up their expected valuations: as much as $120 billion for Uber...

2017

This chapter examines the characteristics and practices of ridesharing users in France. In May 2013, the authors surveyed members of BlaBlaCar, the largest online and app-based carpooling service in France, to analyze the sociodemographic characteristics and usage patterns of the respondents. The survey results identify correlations between socio-demographic characteristics and usage elements. Notably, users with a lower income level are more inclined to be passengers, while higher income users employ carpooling mainly as drivers. Students are shown to be more frequent users as well...

Ridesharing as a Complement to Transit

Paul Minett
2010

Transit and carpooling/vanpooling (ridesharing) can be powerful allies – especially if leveraged together creatively. By embracing ridesharing, transit agencies have been seen to expand their market base, as well as enhance transit operations. Ridesharing can supplement transit services in the high-cost peak period, can serve marginal routes that are costly for transit, and can increase the justification for HOV designations that serve transit as well. If ridesharing and transit alternatives are packaged together, they can attract an even larger market share, displacing the single...
