Model For Predicting The Impact Upon Economic Development Resulting From Highway Improvement Projects, Eric Thompson, Kanou Comlavi, Mallory Dimmit
Model For Predicting The Impact Upon Economic Development Resulting From Highway Improvement Projects, Eric Thompson, Kanou Comlavi, Mallory Dimmit
Nebraska Department of Transportation: Research Reports
The Nebraska Department of Roads (NDOR) has an interest in integrating state economic development impact as another factor in prioritizing transportation investments. Such efforts require the development of a comprehensive model that can be used to estimate a consistent final measure of economic development impact that can be readily integrated into existing prioritization formulas. This report summarizes the efforts of the University of Nebraska-Lincoln Bureau of Business Research (UNL-BBR) to develop such a model, by measuring the impact of expressway, viaduct, and other major investments projects around the state. Specifically, UNL-BBR developed an economic model to predict the economic impact …

Non-Nuclear Method For Density Measurements, Yong-Rak Kim, Yong Cho
Non-Nuclear Method For Density Measurements, Yong-Rak Kim, Yong Cho
Nebraska Department of Transportation: Research Reports
Quality control (QC) and quality assurance (QA) are necessary to ensure fulfillment and compliance to specifications, guidelines, manuals, and programs which outline methods and requirements during construction. Density, an important part of quality control, can be used to evaluate the quality of Hot Mix Asphalt (HMA) and soil compaction. This study investigated new technologies used for QC and QA by comparing the Pavement Quality Indicator (PQI) model 301 with a nuclear gauge and core sample measurements for HMA. For soil QC and QA, non-nuclear technologies—the Electrical Density Gauge (EDG), the Moisture Density Indicator (MDI), and the Light Weight Deflectometer (LWD)—were …

Effectiveness Study On Temporary Pavement Marking Removals Methods, Yong Cho, Jae-Ho Pyeon
Effectiveness Study On Temporary Pavement Marking Removals Methods, Yong Cho, Jae-Ho Pyeon
Nebraska Department of Transportation: Research Reports
This study was conducted to identify effective temporary marking removal methods and procedures on concrete and asphalt pavements. Pavement markings provide guidance to road travelers and can lead to accidents when not properly removed. Current state guidelines on removal do not provide clear and objective methods of measurement. After testing the most common removal methods, this research concluded that removing markings by chemical was not only cost and results-oriented effective compared to other methods, but it was also safe to the environment and road users. Finally, a baseline of measurements was developed by the research team for this project, along …
Analysis Of Existing Work-Zone Sign Supports Using Manual For Assessing Safety Hardware Safety Performance Criteria, Jennifer D. Schmidt, Ronald K. Faller, Karla A. Lechtenberg, Dean L. Sicking
Analysis Of Existing Work-Zone Sign Supports Using Manual For Assessing Safety Hardware Safety Performance Criteria, Jennifer D. Schmidt, Ronald K. Faller, Karla A. Lechtenberg, Dean L. Sicking
Department of Civil and Environmental Engineering: Faculty Publications
Over the years, numerous work-zone, portable sign support systems have been successfully crash tested according to the Test Level 3 safety performance guidelines provided in the National Cooperative Highway Research Program Report 350 and accepted for use along our nation’s highways. For this study, several crashworthy sign support systems were analyzed to predict their safety performance according to the new evaluation criteria provided in the Manual for Assessing Safety Hardware (MASH). More specifically, this analysis was conducted to determine which hardware parameters negatively affect a system’s safety performance. To verify the accuracy of the analysis, eight systems, four with the …

Mid-America Transportation Center: Final Reports and Technical Briefs
Provisions for the design of roadside foreslopes are not readily available. As a result, engineering judgment is often employed. Unfortunately, this can lead to inconsistent designs, where, inevitably, some designs will be too costly and other designs will be too dangerous. Therefore guidance has been compiled to lend consistency to the design of these foreslopes while maintaining the most economical and safe design.
This guidance was prepared after conducting a benefit-cost analysis using the Roadside Safety Analysis Program (RSAP). A large test matrix was developed in an attempt to simulate the most possible scenarios, leaving interpolation to a minimum. However, …
