Since Hurricane Katrina, there has been an increasing focus on disaster relief efforts in the United States. In this paper, the authors examine the progression of transportation management under emergency conditions and opportunities for addressing disasters by leveraging the sharing economy. The sharing economy mobilizes the unused capacity and resources of individuals through mobile and Internet platforms. Notable examples include mobility and the housing sectors. The authors argue here that there is an opportunity to improve disaster preparedness, response, and recovery by...

Charging Infrastructure Demands of Shared-Use Autonomous Electric Vehicles in Urban Areas

Ride-hailing is a clear initial market for autonomous electric vehicles (AEVs) because it features high vehicle utilization levels and strong incentive to cut down labor costs. An extensive and reliable network of recharging infrastructure is the prerequisite to launch a lucrative AEV ride-hailing fleet. Hence, it is necessary to estimate the charging infrastructure demands for an AEV fleet in advance. This study proposes a charging system planning framework for a shared-use AEV fleet providing ride-hailing services in urban area. We first adopt an agent-based simulation model, called BEAM...

Joint Mobility and Vehicle-to-Grid Coordination in Rebalancing Shared Mobility-on-Demand Systems

Vehicle-to-Grid (V2G) technology enables plug-in electric vehicles (PEVs) to act as controllable loads and distributed energy resources for power systems. However, these resources, under the context of Mobility-on-Demand (MoD) market, have yet to be fully exploited for the grid services. This paper investigates how providing energy service from the shared PEVs affects both the power and transportation systems. We consider a shared MoD platform where PEVs can choose to provide either the V2G service or the traveling service when they are rebalanced to future high demand areas. In this...

Carsharing in Europe and North American: Past, Present, and Future

Most cars carry one person and are used for less than one hour per day. A more economically rational approach would be to use vehicles more intensively. Carsharing, in which people pay a subscription plus a per-use fee, is one means of doing so. Carsharing may be organized through affinity groups, large employers, transit operators, neighborhood groups, or large carsharing businesses. While carsharing does not offer convenient access to vehicles, it does provide users with a large range of vehicles, fewer ownership responsibilities, and less cost (if vehicles are not used intensively)....

More car sharing organisations are beginning to appear throughout Europe and North America. The use of existing and new technologies in an innovative way offers tremendous opportunities for this industry to grow.

A Short History of Carsharing in the 90's

From: A Short History of Carsharing in the 90's. Journal of World Transport Policy & Practice 5 (3), 18 - 40 The vast majority of automobile trips in U.S. metropolitan regions are drive-alone car trips. In 1990, approximately 90 percent of work trips and 58 percent of nonwork trips in the United States were made by vehicles with only one occupant (United States Department of Transportation, 1995). Vehicles are unused an average of 23 hours per day. This form of transportation is expensive and consumes large amounts of land. Private vehicles are attractive. Their universal appeal is...

CarLink—A Smart Carsharing System

Susan Shaheen
1999

CarLink is the use of short-term rental vehicles and intelligent communication and reservation technologies to facilitate shared vehicle access at transit stations or other activity centers for making local trips. CarLink vehicles, owned and operated by a transit district or third-party service provider, can be used by different drivers at many locations throughout a day. Using advanced communication and reservation system technologies, they can be reserved in advance or rented automatically upon arrival at a CarLink...

Dynamics in Behavioral Adaptation to a Transportation Innovation: A Case Study of Carlink-A Smart Carsharing System

Susan Shaheen
1999

Most trips in U.S. metropolitan regions are drive-alone car trips, an expensive and inefficient means of moving people. A more efficient system would allow drivers to share cars. Such a system is often less convenient for travelers, but convenience can be enhanced by deploying "smart" technologies in concert with shared-use vehicles and transit. The motivation for this research is to determine how the use of information and communication technologies can enhance flexibility and mobility-and what value travelers will place on these new transportation means.

Evaluation of UC Davis Long-Range Transportation, Land-Use, and Housing Plans: Examining the Potential for Innovative Mobility Pilot Projects

At present, the City of Davis, surrounding communities, and the UC Davis campus are struggling with many of the same transportation problems that plague larger urban centers including increasing traffic, limited parking, and challenges to effective operation of the public transit system. The campus is expecting to grow by 6,000 students in the next ten years (plus approximately 3,000 faculty and staff) and is developing a Long-Range Development Plan (LRDP) that will serve to guide this growth. This plan will include housing, traffic control, parking, alternative transportation modes, and...

Commuter-Based Carsharing: Market Niche Potential

Susan Shaheen
2001

The automobile accounts for more than 95 percent of all person miles traveled in the United States, whereas transit accounts for less than 3 percent of all trips. Between the private automobile and traditional transit, niche markets exist for other transportation services, such as airport and transit feeder shuttles and carsharing. Commuter-based carsharing, by which individuals share a fleet of vehicles linked to transit, could potentially fill and expand one such niche; complement existing services, mainly transit and feeder shuttles; and develop into a viable transportation alternative...
