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...
A regional traffic operations center (TOC) is center for coordinating and supporting transportation system operations by bringing together various jurisdictions to focus on a common goal of optimizing the performance of the system and maximizing its safety and service to the traveling public. A TOC is...
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...
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...
In this paper, findings from a national survey on technology use by agencies providing transit service to rural areas are presented. The survey collected data on agency use of information and communications technologies, transit-specific technology, as well as characteristics of its manager. The survey...
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...
The objective of this project is to examine the feasibility of developing a new transit vehicle, or vehicle specifications, to meet the needs of transit operators and riders. A transit vehicle designed to meet the specific needs of systems will lead to gained efficiencies by transit providers because...
This study reviewed the operations of eight state-run vanpool programs and another seven programs that are run by local units of government. This review focused on the size of each program, funding sources, passenger fares, and overall operations. Some of these services are run with in-house personnel...
This paper reports on a two-year study evaluating HOV lane performance. The analysis assesses the freeway operations before the HOV lanes opened with continued assessment throughout the first year of operation. It looks at automatic data from traffic monitoring stations and manual data from roadside...
