This paper examines the problem of planning an Electric Vehicle (EV) charging facility that provides a high quality of service in charging EVs and incurs a low cost to the facility manager. This problem is challenging because a facility with a larger charging capacity (hence better service quality) can be more expensive to build and operate. This paper contributes to the literature by planning an EV charging facility that overcomes this trade-off and achieves Pareto optimality, i.e. a facility with a higher quality of service but at a lower cost. We propose an optimization model to size an...

Regional seismic hazard analyses are necessary to assess the infrastructure performance within a region and ensure that mitigation funds are utilized effectively by probabilistically considering the suite of potential earthquake events. This research aims to efficiently represent the regional seismic hazard through a compact set of seismic inputs in the form of spectral acceleration (SA) maps by considering the spatial cross-correlation of SA at a wide period range. The SA maps can then be used to probabilistically estimate the performance of a portfolio of spatially distributed structures...

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...

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...
