Filter by Keyword31 report(s) found with operations in the keywords field In an ever-evolving world characterized by environmental challenges and technological advancements, the confluence of natural disasters, particularly increasing wildfire threats, and the role of connected and autonomous vehicles (CAVs) stands as a critical focal point for research and innovation. This... Airport operational data are necessary for aviation decision-makers to quantitatively prepare airport master plans and fairly distribute national funds throughout the country. These data have other important applications, such as safety and security applications. Interestingly, most airports (i.e., typically... Urban traffic networks consisting of partially blocked roads often need to remain open to traffic before, during, and after disasters because of their vital roles to hazard preparation, emergency response, and recovery of urban communities. Conducting effective traffic planning of disrupted transportation... An efficient and timely rescue of injured people by emergency medical services (EMS) is essential to saving as many lives as possible following disasters. Disrupted traffic networks due to the failures of transportation infrastructure (e.g., bridges) following major disasters like earthquakes affect... Innovative intersections and interchanges have proliferated in the State of Utah over the past several years. Continuous flow intersections and diverging diamond interchanges seem to offer improved traffic performance and safety due to their innovative designs. However, there are no clearly defined guidelines... Many Native American tribal governments are lacking in emergency preparedness, a part of the emergency management cycle where planning for disasters happens. These governments need assistance planning for future disasters. Federal, and state governments, along with other agencies and organizations, have... Street networks designed to support Transit Oriented Development (TOD) increase accessibility for non-motorized traffic. However, the implications of TOD supportive networks for still dominant vehicular traffic are rarely addressed. Due to this lack of research, decision making in favor of TOD supportive... This report presents an analysis of freeway incidents on the Salt Lake Valley freeway network. Different types of incidents at the most common/difficult locations are analyzed through traffic microsimulation using VISSIM simulation software. The analysis focuses on incident induced freeway delays, but... This report is a summary of work performed by the Utah Traffic Lab (UTL) to develop training programs for Utah Department of Transportation (UDOT) Traffic Operations Center (TOC) operators. The report includes training materials that are already in service and those additionally developed, at both basic... This report documents the research underway at the Utah Traffic Lab (UTL) that will contribute to the development of the user cost manual. This study evaluates the impact of various work zone scenarios caused by roadway rehabilitation projects in Utah. The results for different scenarios are tabulated... |
