Shared Mobility

Access to transit stations is a significant barrier to transit use in many urban regions. Parking during peak hours is often limited, and many individuals are only willing to walk about a quarter mile to transit stations (Cervero, 2001). While there are some effective feeder services (e.g., shuttles) that help extend the range of transit access, these systems are limited because of fixed routes and schedules. A number of strategies have recently been implemented to improve transit access and transit use, including bicycles, electric bicycles, carsharing, and personal neighborhood electric...

We examine special lanes used by taxis and other shared-ride services to drop-off patrons at airport and rail terminals. Vehicles are prohibited from overtaking each other within the lane. They must therefore wait in a first-in-first-out queue during busy periods. Patrons are often discharged from vehicles only upon reaching a desired drop-off area near the terminal entrance. When wait times grow long, however, some vehicles discharge their patrons in advance of that desired area. A train station in Eastern China is selected as a case study. Its FIFO drop-off lane is presently managed by...

Commuter rail is known to have a “first- and last-mile” problem (i.e., a lack of options for getting commuters to and from a rail station). The first- and last-mile dilemma creates inequalities in access. For example, high-income commuters drive to work (forgoing transit altogether), middle-income commuters drive to a rail station and pay to park, and low-income commuters rely on feeder buses or walking to reach a rail station. Transportation network companies (TNCs), like Uber and Lyft, are a viable option for connecting travelers to rail stations, especially for those who don’t own a car...

Shared-use vehicle services provide members access to a vehicle fleet for use on an as needed basis, without the hassles and costs of individual auto ownership. From June 2001 to July 2002, the authors surveyed 18 U.S. shared-use vehicle organizations on a range of topics, including organizational size, partnerships, pricing, costs, and technology. While survey findings demonstrate a decline in the number of organizational starts in the last year, operational launches into new cities, membership, and fleet size continue to increase. Several growth-oriented organizations are responsible for...
