Transportation Impacts Of The Chicago River Closure To Prevent An Asian Carp Infestation, Aaron Strong Ph.D., Nikhil Sikka Ph.D., Lindsay Salvatore Ph.D.

Mid-America Transportation Center: Final Reports and Technical Briefs

This project develops a simple linear programming model of the Upper Midwest regions rail transportation network to test whether a closure of the Chicago River to freight traffic would impact the capacity constraint of the rail system. The result suggest that the rail network in the Upper Midwest regions are nowhere near approaching capacity and that a closure would have little impact on the rail network. Two noteworthy sets of commodities may be adversely affected, cereal grains and other agricultural product and gravel and crushed stone.

Development & Application Of The Transportation Index For Sustainable Places (Tisp), Jason Zheng

Master's Theses

The purpose of transportation systems go beyond the movement of people and goods. These systems shape the natural and built environment which subsequently affects social and economic interactions. However, conventional metrics typically only address the mobility aspect of transportation via measures such as level of service and congestion. Metrics are needed to evaluate the broader impacts of transportation.

This work describes the Transportation Index for Sustainable Places (TISP), a performance metric designed to assess the sustainability of transportation systems with respect to environmental, social, and economic outcomes. The development of the TISP was guided through literature review focused on understanding …

The Impacts Of Road Capacity Removal, Jason E. Billings

Master's Theses

The road infrastructure of North America is aging, and many governments are faced with a critical decision:  do we repair or remove freeways from our urban centers?  Freeway repair is exceptionally expensive, but removing a freeway is widely seen as a risky venture which may result in negative traffic effects.  Therefore, it is necessary to gain a clearer understanding of how removing road capacity effects traffic distribution.  Three freeway segments were ultimately selected for case study analysis: two in San Francisco and one in Milwaukee.  This analysis consisted of identifying changes in the traffic volumes and volume-capacity (V/C) ratios in …

This report looks at the potential financial impact of LD 1725 on the estimated 30,000 stream crossings in the State of Maine that would be affected by the law. Our research for this report included the analysis of nearly 2000 stream crossings and the data collection necessary for the development of extensive stream crossing replacement cost models. We found that the 1.2 bankfull requirements in LD 1725 would result in a 75% ‐ 250% increase in structure widths for stream crossing projects across the state. An upsize of this magnitude would increase the cost of replacing stream crossings statewide by …

Safety Evaluation Of Work Zone Practices In Utah, Tomás Ernesto Lindheimer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Work zones present a risk to drivers and to personnel constructing the roadway. In 2005 work zones accounted for 2.5% of fatalities nationwide, 3.5% for the state of Utah. The goal of this research is to make work zones safer by quantifying the risk that they present to drivers. The approach of this research has been to review part 6 of the Manual of Uniform Traffic Control Devices (MUTCD) and compare the differences from the 2003 and 2009 editions, conduct field studies of Utah work zones, and develop a tool for measuring risk in work zones. In the 2009 MUTCD …

Evaluation Of Utility Relocation Costs And Best Management Practices, Michael Reinke

All Theses

In recent years, the SCDOT has experienced a significant variation in estimated costs for the relocation of utilities on many projects. This has led to cost overruns and caused concerns for the district engineers responsible for the projects. Through meetings with SCDOT personnel and utility company representatives it was determined that a standardized cost estimate form combined with improved change order management and cost management strategies was needed. Recently submitted estimates were analyzed and rated by a panel on multiple criteria to generate a list of 'poor', 'good', and 'excellent' estimates. The 'excellent' estimates provided insight into the development of …

Transportation Network Resiliency: A Fuzzy Systems Approach, Nayel Urena Serulle

Traffic Safety Investigations For Local Agencies, Jacob D. Hudson

Master's Theses

National and statewide (California) collision numbers are currently on the

decline; however, the U.S. is declining at a much slower rate than most other

developed countries, and in some aspects is actually regressing in terms of traffic

safety. Although state highway safety is improving, local roadway safety may

actually be regressing. Approximately three-quarters of all U.S. public roadways,

and approximately 80% of all injury accidents fall under the jurisdiction of cities.

However, cities may not be allocating the proper level of resources, or operating

under the proper administrative methodologies to adequately address these

safety issues.

This research finds that on …

Analyzing The Effectiveness Of Safety Measures Using Bayesian Methods, Daniel J. Thurgood

Theses and Dissertations

Recent research has shown that traditional safety evaluation methods have been inadequate in accurately determining the effectiveness of roadway safety measures. In recent years, advanced statistical methods have been utilized in traffic safety studies to more accurately determine the effectiveness of roadway safety measures. These methods, particularly hierarchical Bayesian statistical techniques, have the capabilities to account for the shortcomings of traditional methods. Hierarchical Bayesian modeling is a powerful tool for expressing rich statistical models that more fully reflect a given problem than a simpler model could. This paper uses a hierarchical Bayesian model to analyze the effectiveness of two types …

Developing A Sustainable Freight Transportation Framework With The Consideration Of Improving Safety And Minimizing Carbon Emissions, Margaret Rita Neff, Yong Bai, Steven Schrock, Thomas E. Mulinazzi

Mid-America Transportation Center: Final Reports and Technical Briefs

Despite the difficulties of the American economy in recent years the transportation sector continues to expand. Freight transportation alone has been projected to increase enormously even if the economy as a whole only manages a very moderate growth. Not only does freight transportation use a large percentage of resources but it contributes significantly to America’s share of carbon emissions and affects the safety of the transportation system and all its users. These problems are only expected to increase as the volume of freight transportation is already reaching the limit of the American transportation infrastructure’s capacity and demand continues to increase. …

The Impacts Of Biofuels On Transportation And Logistics In Indiana, Frank Dooley, Wallace Tyner, Kumares C. Sinha, Justin Quear, Lydia Cox, Maria Cox

JTRP Technical Reports

Like the rest of the US, the ethanol industry in Indiana has rapidly expanded, growing from one plant in 2006 to a projected 13 by 2010. One result of this expansion is that truck and rail traffic flows in Indiana are shifting, as more corn and beans are processed in state. Most of the change in transportation requirements will likely be concentrated in regions of Indiana where the ethanol plants are constructed.

The goal of this work was to determine how the entry of ethanol and biodiesel plants changes the inbound and outbound transportation flows of corn, soybeans, DDGS, and …

A Prioritization Process For Access Management Implementation In Utah, Kordel T. Braley

Theses and Dissertations

Appropriate access management techniques can improve the safety and efficiency of arterial roads. In order to determine which roads can most benefit by the implementation of access management techniques, a prioritization process was developed to recommend various access management treatments such as limiting access points, installing raised medians, and ensuring adequate signal spacing along corridors. To serve as the basis for the performance index, a database was created including identifying features, characteristics, and crash history for 175 arterial road segments on Utah state routes. Stepwise linear regression was applied to the data collected to determine which characteristics of the roads …

Culture, Justice And The Arnstein Gap: The Impact Of Structured Public Involvement On U.S. Transportation Infrastructure Planning And Design, Keiron Bailey, Ted H. Grossardt

Kentucky Transportation Center Faculty and Researcher Publications

Enormous quantities of public money are spent on transportation infrastructure (TI). According to the Bureau of Transportation Statistics this infrastructure spend in the U.S. amounted to almost $90 billion in 2001. In most political spheres, when public money is spent, the public demands a measure of accountability. The dimensions of this accountability depend on the character of the political system that funds TI. In most participatory democracies, ultimate accountability is exercised through a balloting system that ensures elected officials represent, to some degree, stakeholder views and preferences. However, despite enormous expenditure of public monies on TI, this type of accountability …
