Research Reports
View AllLocal transportation agencies in the Salt Lake City (SLC) Metropolitan Area spent more than a decade working toward building a sustainable regional transportation system. Light Rail Transit (LRT) is an integral part of that system. Currently, three LRT lines operate along the Wasatch Front area. A new... Due to the recent oil boom, the Fort Berthold Reservation has experienced a dramatic increase in highway and local traffic. To support energy transportation and provide safe roads, the reservation needs cost-efficient and effective transportation planning for present and future needs. A quality road... Multitasking may diminish the self-awareness of performance that is often essential for self-regulation and self-knowledge. Participants in an experiment drove on a simulator while talking or not talking on a cell phone. The errors they made while driving were recorded. Following previous research, participants... This report presents an initial investigation of the mechanics of I-beams developed with plastic-aluminum composite technology. Plastic-aluminum composites in structural beam/frame/truss elements are a relatively new concept that has seen little, if any, application in modern construction. This technology... Grouted Splice Sleeve (GSS) connectors are being considered for connecting bridge columns, footings, and pier caps in Accelerated Bridge Construction (ABC). A repair technique for precast reinforced concrete bridge column-to-footing and column-to-pier cap joints constructed with GSS connectors has been... This report describes methods that potentially can be incorporated into the performance monitoring and planning processes for freeway performance evaluation and decision making. Reliability analysis was conducted on the selected I-15 corridor by employing congestion frequency as the performance measure.... This effort responds to a North Dakota League of Cities request for a study of the transportation needs of the largest 14 urban centers in the state. The study was funded by the North Dakota League of Cities and the North Dakota Department of Transportation. The North Dakota League of Cities, along with... Traffic congestion mitigation is one of the key challenges that transportation planners and operations engineers face when planning for construction and maintenance activities. There is a wide variety of approaches and methods that address work zone impacts, starting with simple equations, over spreadsheets... Because existing models have their limitations, there is a significant need for a model to estimate demand for intercity bus services, especially in rural areas. The general objective of this research was to develop an intercity mode choice model that can be incorporated into a statewide travel demand... Alan Dybing, Andrew Wrucke, Brenda Lantz, Bradley Wentz, Denver Tolliver, Kimberly Vachal, Timothy Horner, Dale Heglund, Thomas Jirik, Leanna Emmer, Doug Hoopman, Mark Berwick, and Robert Shannon This effort responds to the North Dakota Legislature's direction to North Dakota Department of Transportation (NDDOT) to collaborate with the Upper Great Plains Transportation Institute (UGPTI) to study the impacts in North Dakota of harmonizing truck size and weight regulations with states in the western... |
