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...

The information in this report is Phase I of a three-phase study, which provides for identification and discussion of North Dakota's direction for state freight planning, important freight gateways, and relationships that are instrumental in the state's economic productivity.

This paper evaluates the impact of various I-15 reconstruction closure scenarios on the travelers in the Ogden area. The purpose of the research was to investigate the impact of the scenarios and facilitate decisions about future maintenance of traffic during the reconstruction.

This report identifies several factors critical to the success of short line rail roads. Success was measured and analyzed by looking at variables related to traffic volume, backhaul traffic, reliance on industries and/or commodities, number of shippers, flexibility of labor, track conditions, management...

This report examines the potential role of a new form of transportation intermodal truck-rail container transportation in the state's expanding manufacturing and value-added agricultural base. It explores the general advantages of intermodal container transportation, examines factors that make intermodal...

Executive Summary of DP-150

This study examines signal timing in inclement weather conditions. With the completion of the Utah DOT's Advanced Traffic Management System (ATMS), UDOT will have the capability to change signal timing plans from a central location by communicating with each controller through fiber optic technology....

This study compares the performance of left-turn phasing to provide quantifiable benefits of one phasing over another. From the analysis, guidelines are developed for determining the type of left-turn phasing based on left-turn volume, opposing through volume and lane geometry.

This paper presents a prototype safety improvement program (SIP), which was developed specifically for unpaved roads. The combination of high mileage, low traffic volume, and limited budgets make it difficult for local agencies to adopt traditional safety improvement programs. The SIP for unpaved roads...
