Investigating the effect of freeway congestion thresholds on decision-making inputs

Description: "This research investigated the differences inherent in the threshold choices using detailed freeway data from seven metropolitan areas. Congestion performance measures of delay per mile, Travel Time Index and Planning Time Index were evaluated. This research specifically examined: 1) the ranking values of congestion measure for different congestion thresholds under a variety of real-world travel time distributions, 2) the relationship between change of congestion threshold and change of performance measure, and 3) the appropriateness of using speed limit as a congestion threshold choice by evaluating the peak and off-peak average speed changes in relation to speed limit change in Houston, Texas."

Evaluating the Use of Transfers for Improving Rural Public Transportation Systems

Description: "In this report researchers consider a variation of the regular demand responsive transit system that adopts the transfer practice to reduce operating costs.Researchers evaluated the effect of different transfer operating policies by developing a simulation model of several plausible scenarios. The results indicate that zoning with transfer can provide significant benefits paratransit operations that are managing zoning structure."

The Short-Run Impact of Gas Prices on Toll Road Use

Description: One of the primary functions of transportation planning is to predict future travel behavior. Using estimated travel patterns, planners can then help decision makers select the array of projects that will best suit the needs of their community. Travel behavior is a function of many variables, with cost being among the most important. Recent fluctuations in the price of gas provide an excellent opportunity to observe the impact of the price of gas on travel behavior. This project goes a step beyond looking at the elasticity of travel with respect to gas price by examining how recent changes in gas prices have impacted travel on specific facilities: toll facilities. Data from around the US was used to examine how traffic levels on toll roads have been affected by fluctuations in gas prices over the last several years. This study developed models that account for the many other exogenous factors influencing toll road use (such as local economy, population, and toll rates), and provide an elasticity of toll road demand with respect to gas price independent of those other factors. This study will provide planners and toll road authorities with valuable information on how travelers react to increasing cost of travel when already selecting a mode with an added cost (the toll). The research findings indicated that travel demand elasticity estimates with respect to gas price were inelastic and mostly negative. Elasticities found here for the period from 2000 to 2010 ranged from -0.36 to +0.14, similar to those found in the literature for non-toll facilities. However, the average value of the elasticities found here were much smaller (closer to -0.06) than those found for non-toll facilities.

The 2011 Mileage-Based User Fee Symposium

Description: The fuel tax is rapidly losing its ability to support system needs. Federal environmental regulations and the escalating price of fossil fuels have created a strong incentive to develop and utilize more fuel-efficient vehicles, which will drive down fuel tax revenues relative to use of the nation's roadway network. Given the challenges associated with the declining sustainability of the fuel tax, the likely successor is a road user fee largely based on actual usage. This project sponsored the third annual two-day Symposium on Mileage-Based User Fees that brought together professionals in the field of mileage-based fees for the purpose of sharing information on current applications and exploring their potential as a supplement or replacement for the fuel tax.

Development of a Special Topics Course on Civil Engineering Project Finance for the Zachry Department of Civil Engineering of Texas A&M University

Description: A project finance course integrated into the core curriculum for graduate civil engineering students. Even fewer programs treat project finance as a truly interdisciplinary topic. In fact, the topic of project finance often constitutes only a small part of the structured finance curricula. The purpose of this project was to bridge this gap by developing educational and teaching materials for an interdisciplinary course in project finance. This course communicates the implications of financial decisions on engineering choices and vice versa. The course is directed toward graduate students at the Master of Science level to better prepare them to deal with real-world transportation financing.

The Value of Public Transportation for Improving the Quality of Life for the Rural Elderly

Description: "This report focuses on non-medical transportation; medical transportation is addressed in the literature and is more widely available to the elderly. Because expanded rural transportation systems likely will be funded by taxpayers, an understanding of their preferences and willingness-to-pay for non-medical transportation options is essential."

Facilitating creation of transit system technology user groups

Description: "In recent years, a number of rural transit providers in Texas have purchased computer software to enhance trip scheduling and dispatching. However, many of these agencies are using the software primarily as a recordkeeping system, not as a management tool. Rural providers report that staff too often is not sufficiently familiar with the software capabilities, and the agency is not receiving a good return on the technology investment. The purpose of this research was to inventory current technology applications and vendors by transit agency and to assess the current use(s) of these applications. The researchers also documented plans for technology upgrades or expansions and identified the current technology issues faced by providers. Texas Transportation Institute (TTI) researchers contacted the rural and state-funded urban transit districts in Texas to determine the types of technology currently used or in procurement. Researchers provided the results of this research to all rural and state-funded urban transit districts to enable providers to share and gain from their mutual experiences and to leverage influence with software vendors to address mutual concerns and interests. Researchers facilitated a panel discussion at the Texas Department of Transportation, Public Transportation Division's Semi-Annual Transit Provider Meeting in July 2010 as a way to share experiences about technology implementation. TTI researchers recruited transit agency representatives to serve on the panel. Based on the panel discussion and research findings, researchers recommend technology mentoring and Web-based user community support programs. These programs will support the continued and expanded implementation of technology among rural and small urban transit agencies."

Developing an Interdisciplinary Certificate Program in Transportation Planning

Description: This proposal extends the delivery of the recently developed graduate Certificate in Transportation Planning to a wider audience through the establishment of an Executive Certificate Program by distance (eCertificate). While the need for an interdisciplinary approach to transportation is widely recognized by the professional community, there are few educational programs that address the field of transportation in a truly comprehensive, interdisciplinary manner. Texas A&M University's (TAMU's) university-wide graduate Certificate in Transportation Planning was established in August 2008 to address this need. This program has proved to be very successful. A limitation of the existing certificate program is that it is available only to graduate students at TAMU in College Station. The eCertificate program extends the delivery of the existing certificate to a wider audience of professionals interested in transportation in selected metropolitan areas in Texas. Preliminary indications suggest that an audience for the certificate exists in major metropolitan areas in Texas, especially Austin, Dallas, Houston, and San Antonio. The certificate will increase access, expand Texas A&M's transportation curriculum, and enhance the university's position as a national leader in transportation education.
