Equity evaluation of vehicle miles traveled fees in Texas

Equity evaluation of vehicle miles traveled fees in Texas

Date: March 2012
Creator: Burris, Mark
Description: "This report used 2009 National Household Travel Survey (NHTS) Texas data to consider the equity impacts surrounding four vehicle miles traveled (VMT) scenarios. Results indicate that all of the VMT fee scenarios are essentially as equally vertically equitable as the current state gas tax system."

Use of Micro Unmanned Aerial Vehicles for roadside condition assessment

Use of Micro Unmanned Aerial Vehicles for roadside condition assessment

Date: December 2010
Creator: Gharaibeh, Nasir G.
Description: "Micro Unmanned Aerial Vehicles (MUAVs) that are equipped with digital imaging systems and global positioning systems provide a potential opportunity for improving the effectiveness and safety of roadside condition and inventory surveys. This study provides an assessment of the effectiveness of MUAVs as a tool for collecting condition data for roadside infrastructure assets using three field experiments."

Managing commodity risks in highway contracts: quantifying premiums, accounting for correlations among risk factors, and designing optimal price-adjustment contracts

Managing commodity risks in highway contracts: quantifying premiums, accounting for correlations among risk factors, and designing optimal price-adjustment contracts

Date: September 2011
Creator: Damnjanovic, Ivan
Description: "The main goal of this report is to investigate the impact of commodity price risk on construction cost and the optimal risk hedging of such risks using price adjustment clauses. More specifically, the objective of the report is to develop models that can help highway agencies manage commodity price risks. In this report, weighted least square regression model is used to estimate the risk premium; both univariate and vector time series models are estimated and applied to simulate changes in commodity prices over time, including the effect of correlation; while genetic algorithm is used as a solution approach to a multi-objective optimization formulation. The data set used in this report consists of TxDot bidding data, market-based data including New York Mercantile Exchange (NYMEX) future options data, and Engineering New-Record (ENR) material cost index data. The results of this report suggest that the optimal risk mitigation actions are conditional on owners' risk preferences, correlation among the prices of commodities, and volatility of the market."

How fast is a fast train? : comparing attitudes and preferences for improved passenger rail service among urban areas in the South Central high-speed rail corridor

Date: December 2011
Creator: Morgan, Curtis Alan
Description: "Using data from an Internet-based survey of residents in three communities in Central Texas-Waco, Temple, and Hillsboro-this research project examined the potential impacts of new intercity passenger rail service on small-or medium-sized communities located in the intermediate area between two larger urban areas that form the endpoints of a federally designated intercity high-speed rail corridor."

Potential connected vehicle applications to enhance mobility, safety, and environmental security

Potential connected vehicle applications to enhance mobility, safety, and environmental security

Date: February 2012
Creator: Balke, Kevin N.
Description: "Researchers first conducted a comprehensive review of the state-of-the-art connected-vehicle research and technologies. Once researchers had a thorough understanding of the technology, they focused on selecting and developing the near-term practical applications that use connected vehicle technology. The research team then sought expert opinions from the Texas Transportation Institute working group during two brainstorming sessions, which produced two lists of potential applications and prioritized the applications based on deployment feasibility. In particular, a total of five applications were selected for development of the full concept of operations, including two in safety, two in mobility, and one in environmental security. These applications address various problems, including wrong-way driving and unprotected-grade-crossing crashes (safety): work-zone merge efficiency and safety, and freeway speed harmonization (mobility): and slippery pavement-related crashes (environmental security)."
