Development of a model performance-based sign sheeting specification based on the evaluation of nighttime traffic signs using legibility and eye-tracker data
Date: September 2010
Creator: Carlson, Paul J.
Description: "This report focused on the evaluation of traffic sign sheeting performance in terms of meeting the nighttime driver needs. Using the luminance requirements derived from the study and market-weighted headlamp flux matrices, the researchers developed an approach to sigh sheeting specification that is based on nighttime driver needs."

Evaluation of traffic control devices : year 3
Date: March 2012
Creator: Carlson, Paul J.
Description: This project was established to provide a means of conducting small-scale research activities on an as-needed basis so that the results could be available within months of starting the specific research. This report summarizes the research activities that were conducted between September 2010 and August 2011. There were five primary activities and five secondary activities. The five primary activities were evaluating nighttime visibility along rural highways with bright signs, continuing the evaluation of lead-free thermoplastic pavement markings, evaluating contrast pavement marking layouts, continuing the evaluation of accelerated pavement marking test decks, and providing district support for hurricane evacuation routing. In addition, the researchers also started to evaluated criteria for setting 80 mph and 85 mph speed limits, evaluated bridge clearance signing, narrowed the focus of a rotational sign sheeting study, provided technical support for the Texas Manual on Uniform Traffic Control Devices (MUTCD), and provided technical support for the Texas Department of Transportation (TxDOT) sign sheeting specification.

Research and recommendations for a statewide sign retroreflectivity maintenance program
Date: April 2012
Creator: Carlson, Paul J.
Description: "This report evaluated Texas Department of Transportation's (TxDOT) current sign retroreflectivity maintenance practices, assessed their effectiveness, and recommended statewide sign retroreflectivity maintenance practices that could be easily and effectively implemented to ensure that TxDOT would be in compliance with the new Manual on Uniform Traffic Control Devices (MUTCD) language related to minimum sign retroreflectivity."

Development of warrants for installation of dual right-turn lanes at signalized intersections
Date: April 2012
Creator: Chen, Xiaoming
Description: "Right-turn lanes provide space for the deceleration and storage of right-turn vehicle, and separate turning vehicles from through movements. Dual right-turn lanes are increasingly used at urban intersections primarily for two reason: (1) to accommodate high right-turn demands and avoid turn-pocket overflows, and/or (2) to prevent right-turn vehicles that exit from a nearby upstream freeway off-ramp (on the left of the roadway) from abruptly changing too many lanes toward the right-turn lane at intersection."

Transit management certificate program
Date: July 2012
Creator: Cherrington, Linda
Description: "In this report Texas Transportation Institute(TTI) worked closely with the Landscape Architecture and Urban Planning Department (LAUP) of Texas A&M University (TAMU) to develop a transit management certificate focus for the current Graduate Certificate in Transportation Planning (CTP) housed in the College of Architecture at TAMU. This program is the first step in the development of future educational opportunities in public transportation in Texas."
