A Safety Analysis Of Roundabouts In The Las Vegas Valley Clark County, Nevada, Michael J. Janssen Apr 2003

A Safety Analysis Of Roundabouts In The Las Vegas Valley Clark County, Nevada, Michael J. Janssen

UNLV Theses, Dissertations, Professional Papers, and Capstones

This professional paper reviews current research on the safety of modern roundabouts and studies the recent, widespread use of them in the Las Vegas valley of Southern Nevada. A roundabout is a form of intersection control (as opposed to a traffic signal or stop sign) that is common in Europe and Australia. Only recently have they been used significantly in the United States. A safety analysis of roundabouts in the Las Vegas Valley was conducted. The study reviewed accident data and hard copy accident reports, obtained average daily traffic counts, and compared these operational aspects of the roundabouts with intersections …

An Analysis Of Multiple Layered Networks, Kevin T. Kennedy Mar 2003

An Analysis Of Multiple Layered Networks, Kevin T. Kennedy

Theses and Dissertations

Current infrastructure network models of single functionality do not typically account for the interdependent nature of infrastructure networks. Infrastructure networks are generally modeled individually, as an isolated network or with minimal recognition of interactions. This research develops a methodology to model the individual infrastructure network types while explicitly modeling their interconnected effects. The result is a formulation built with two sets of variables (the original set to model infrastructure characteristics and an additional set representing cuts of interdependent elements). This formulation is decomposed by variable type using Benders Partitioning and solved to optimality using a Benders Partitioning algorithm. Current infrastructure …
