This research develops a two-stage approach for estimating a statewide truck origin-destination (O-D) trip table. The proposed approach is supported by two sequential stages: one estimates the commodity-based truck O-D trip table primarily derived from the commodity flow database, and the other refines...
Urban freight planning is more complex than urban passenger transport in many respects. The complexity of the planning process arises from the fact that (i) movement of freight in an urban area is part of a logistics chain for diverse goods moved from points of production via warehouses and distribution...
The main objective of rural roadway pricing is revenue generation, rather than elimination of congestion externalities. This report presents a model that provides optimum tolls accounting for pavement deterioration and economic impacts. This model contains multiple components, because imposing tolls...
Two-dimensional, depth-averaged flow models are used to study the distribution of flow around spill-through abutments situated on floodplains in compound channels and rectangular channels (flow on very wide floodplains may be treated as rectangular channels). The study leads to useful insights regarding...
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)...
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...
In 2005, the Utah Department of Transportation (UDOT) installed the Sydney Coordinated Adaptive Traffic System (SCATS) in Park City, Utah, on its network of 14 signalized intersections. A field evaluation compared previous time-of-day actuated-coordinated signal timings with those dynamically computed...
This research evaluates the effectiveness of the future Utah Department of Transportation (UDOT) adaptive signal control system on the arterial street network in Park City, Utah, that experiences both everyday and unpredictable changes in traffic flow. This report contains the planned methodology for...
Increasing traffic congestion is a constant source of frustration, time loss, and expense to users and managers of transportation systems. Cities, counties, and state transportation agencies are persistently searching for ways to mitigate urban traffic congestion, while minimizing costs and maintenance...
