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...
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...
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...
The study surveyed small to medium size agencies, ranging from 700 to 17,000 trips per month. The results clearly indicated that all of the agencies in this range benefited from low cost computer software for the purposes of making trip reservations, scheduling trips, dispatching trips, record keeping...
This paper summarizes the results of a study on direct assessment of rural user needs in Montana, North Dakota and South Dakota. The objective was to assess rural road users and providers perceptions of rural road needs. Different rural road user groups were identified to obtain a representative sample...
Voluntary turnover rates among truckload carriers are extremely high, ranging from 50 to more than 100 percent annually. These high turnover rates result in elevated costs for carriers in terms of recruitment and training as well as costs associated with reduced productivity and decreased customer satisfaction...
This research focuses on real-time congestion monitoring, a unique direction, as most other cities focus solely on freeway operations as they are easier to monitor. Once surface street congestion is monitored successfully, recurring problematic locations can be identified, and solutions can be developed...
This report contains a brief description of Intelligent Transportation Systems (ITS) and ITS technologies for Commercial Vehicle Operations (ITS/CVO). Second, it discusses previous literature regarding benefits of ITS/CVO for motor carriers, as well as managing the change due to technology. In addition...
