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

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

Date: May 2010
Creator: Qu, Tongbin
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."

Texas Urban Triangle: creating a spatial decision support system for mobility policy and investments that shape the sustainable growth of Texas

Texas Urban Triangle: creating a spatial decision support system for mobility policy and investments that shape the sustainable growth of Texas

Date: November 2010
Creator: Bright, Elise M.; Morgan, Curtis Alan & Neuman, Michael
Description: "This project came into being due to the dramatic transformation of the four core Texas metropolitan areas into an emergent megalopolis: Dallas-Fort Worth, Houston, San Antonio, and Austin. Its aims are two-fold: to provide a framework for decisions about future growth in the fastest growing region of Texas, and to spur further research into the complexities of this vast and rapidly emerging mega-region. The Texas Urban Triangle - 17 million persons spread over 58,000 square miles - is a new urban phenomenon, a triangular megalopolis whose development is not linear and contiguous. This report gives policy makers and investors from all sectors of society the critical knowledge they need to make decisions that will shape the future of Texas. The Texas Urban Triangle is one of the most dynamic urban regions in the nation, and to ensure it continues to flourish, we must build a future based on sustainable growth principles. Our preliminary findings suggest that this is not always the case. Further research needs to be conducted to obtain a complete, detailed, and comprehensive portrait. Nonetheless, even these preliminary findings are robust and point to more sustainable options for the future. Now that this preliminary analysis has been completed, ...

Intercity passenger rail: implications for urban, regional, and national mobility

Intercity passenger rail: implications for urban, regional, and national mobility

Date: December 2011
Creator: Sperry, Benjamin R. & Morgan, Curtis Alan
Description: Recent policy and regulatory actions by the U.S. government have revived interest in intercity passenger rail among transportation planners, policymakers, and the general public. As part of a fully integrated multimodal intercity corridor, passenger rail can provide a number of measurable impacts on urban, regional, and national mobility. This research examines these impacts using the Milwaukee-Chicago Hiawatha Service intercity passenger rail route as a case study. In addition to providing competitive travel times with automobile travel and frequent daily service, rail passengers can also seamlessly connect to airline service via a station at the Milwaukee airport. Two data sources--an on-board survey of Hiawatha Service passengers and a more detailed survey of air-rail transfer passengers at the Milwaukee airport--were used to identify the mobility impacts of rail service. If the rail service did not exist, most Hiawatha Service passengers would travel via personal vehicle, which indicates that the Hiawatha Service is providing congestion relief for the highways parallel to the route. The airport link allows for sustainable ground access to the Milwaukee airport and also extends the market area for the airport into the Chicago region, providing those residents with greater choices in air travel. The findings of this project provide ...

Creating the next generation of transportation professionals

Creating the next generation of transportation professionals

Date: November 2011
Creator: Finley, Melisa D. & Jasek, Debbie
Description: The transportation industry, like every other profession that relies heavily on the science, technology, engineering, and mathematics (STEM) fields, faces a growing shortage of professional engineers. The purpose of this project was to investigate new methods for conducting educational outreach activities for kindergarten through twelfth grade (K-12) students and compare the effectiveness of various implementation methods. During this project, Texas Transportation Institute (TTI) researchers developed two in-class educational outreach modules and several displays that they could easily transport and exhibit at various educational outreach activities. The first in-class module introduces intermediate school students to the world of transportation and transportation engineering and teaches students about the principle of retroreflectivity. The second in-class module teaches kindergarten students about sign shapes and colors. TTI researchers also participated in 12 educational outreach activities. These activities included: Four in-school events, four field trips to TTI facilities, three summer activities, and one engineering day event. The students participating in these activities ranged from kindergarten to twelfth grade. The educational outreach activities conducted introduced the fields of transportation and engineering to over 2000 students.
