Identification of priority rail projects for Texas: initial methodology/user manual and guidebook

Identification of priority rail projects for Texas: initial methodology/user manual and guidebook

Date: February 2012
Creator: Morgan, Curtis Alan
Description: "This project developed a system of evaluative tools for the Texas Department of Transportation (TxDOT) to prioritize its investments in rail-related projects on a statewide basis. This work is meant to ensure that the limited available funding for rail projects is applied in the most beneficial and efficient manner and is focused upon addressing TxDOT's strategic goals. From the findings, researches recommend a transparent methodology for evaluating proposed rail projects and establishing an initial process through which rail-related investments can periodically be re-evaluated."

Evaluation of traffic control devices : year 3

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

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."

Positive feedback :  exploring current approaches in iterative travel demand model implementation

Positive feedback : exploring current approaches in iterative travel demand model implementation

Date: January 2012
Creator: Reeder, Phillip
Description: This report looked at the current Texas Department of Transportation Travel Demand Model (TxDOT TDM) and found that they do not include any impedance or accessibility measures in the trip generation step and found that the best approach is to feed back the output from the traffic assignment step to the trip distribution step.
