The goal of this study is to evaluate light rail priority strategies along the 400 S / 500 S corridor in Salt Lake County through analyzing benefits and impacts of the priority on transit and vehicular traffic through microsimulation. The results show that the existing priority strategies have no impacts...
This study evaluates the impact of proposed replacement on the travelers in Summit County. The purpose of this research is to provide UDOT an estimation of possible delay costs due to congested traffic resulting from the proposed work zone scenarios. The VISSIM micro-simulation tool is used to build...
This paper is a summary of work performed by the Utah Traffic Lab (UTL) to develop training programs for the Utah Department of Transportation (UDOT) Traffic Operations Center (TOC) operators at both the basic and advanced levels. The basic training is designed to train operators in the basic knowledge...
Occupant protection is one of the easiest and most inexpensive ways to protect yourself when riding in a motor vehicle. Yet many North Dakota youth, especially rural youth, fail to wear their seat belts, even with a primary seat belt law for children under the age of 18 in the state of North Dakota....
Modeling and developing different evacuation scenarios gained significant interest in recent years, where the management of the transportation system in support of evacuation efforts proved to be critical in mitigating the impacts of regional emergency events. However, most of the evacuation modeling...
With ever-increasing traffic demand and price of fossil fuels public transit becomes more popular transportation mode than ever before, especially in the fast growing regions such as Salt Lake City Metropolitan Region. Wasatch Front Regional Council (WFRC) (a local Metropolitan Planning Organization)...
Improving roadway safety is an ongoing priority for transportation agencies. However, addressing safety issues in rural areas is difficult for local governments due to the limited resources available for maintenance and improvement projects. Traffic Safety Evaluations (TSE's) have emerged as an effective...
Earthquakes damage transportation infrastructure. In addition to replacement and repair costs for damage to transportation structures, large earthquakes can increase time delays resulting from a network component's loss of function. Damage to the network can severely disrupt traffic flows for several...
The impetus of this research is to meet the growing need for accurate and practical methods to support traffic analysis in work zones. This research examines the application of two classes of traffic analysis models, macroscopic sketch analysis and microscopic traffic simulation, to work zones. The research...
An integrated mobile testing study that utilized a large truck equipped with various testing equipment was conducted on Interstate I-70 in Colorado. The field study integrated wind measurement, vehicle dynamic monitoring and geospatial multimedia technology on a real-time and synchronized basis. Essential...
