World Durum Trade Model (Sep 1994, MPC-94-35)

The objective of this study was to assess the competitiveness of U.S. durum producers in supplying durum by estimating production levels and trade flows under alternative trade scenarios. Mathematical programming was used to compare production levels and distribution patterns for the durum market under...

This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the effect of construction Profilograph Index (PI) values on long-term roughness measurements of concrete pavements. The objectives of this study were to determine if increased...

In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut...

The primary objective of this research was to establish statistically valid mathematical models that can explain the variations in accidents as a function of geometric variables. Engineers and planners will be able to use these models to examine the sensitivity of accident rates to any of the independent...

This paper examines the effectiveness of applying chip seal friction courses in reducing accidents on low volume, rural roads. Chip sealing data from District 3 of the Utah Department of Transportation were used to examine accident rates before and after applying chip seal. Although accident rates generally...

This report describes the transportation workshops conducted during June 1993, under the Summer Experiential Learning Program for Diverse Student Populations. The goal of this project was to provide an opportunity to interest minority students in the region in pursuing a college education in the field...

The GEOTRANS (GEographical Optimizer for TRANSportation) is an implementation of a GDSS for rural transportation. Algorithms and specialized data structures were developed to accomplish accurate and efficient solutions of a suite of network flow optimization models for use in GEOTRANS. The design of...

The Wyoming loop tour program, as evaluated in this study, involved two components. One component dealt with the location criteria and an evaluation of the existing loop tours which is contained in a companion report, MPC 94-29. Included in this study is a discussion of models used in determining economic...

In this research, criteria were developed for designating and evaluating scenic loop tours based on roadway conditions, scenic beauty, number of local communities, population, and anchor attractions. Two existing scenic loop tours in Wyoming -- the Cheyenne and Oregon Trail Loop Tour and the Bighorns...

This project is ongoing at Colorado State University to study road dust suppressants with the objective of measuring the relative effectiveness in this semi-arid region as well as any water quality degradation resulting from this usage. Five test sections are being evaluated in this research project...
