Research Digest Item 1 Implementation of Electronic Appraisal System UNIVERSITY OF TEXAS AT AUSTIN. CENTER FOR TRANSPORTATION RESEARCH (CTR) CTR 1523-03-1 • 2009 Research project 9-1523 is a Texas-led study supported by national pooled funds which has developed a prototype Electronic Appraisal System (EAS). The EAS streamlines the review and approval process for real property acquisition by allowing the capture, transmission, storage, management, analysis and reporting of appraisal data in a secure electronic format. The prototype was unveiled at the May, 2006 AASHTO Right-ofWay Conference in Baltimore, and has met with wide acceptance by state DOT R/W personnel. However, the prototype is only a proof-of-concept for the EAS. It was built to demonstrate the key features of the proposed EAS with limited functionalities. In order to implement the EAS for TxDOT use, a new appraisal report template was provided by the ROW Division of TxDOT in April, 2009. Certain features of the prototype system must be customized to the local conditions of Texas while some other features of the prototype must be further enhanced and/or fine-tuned according to this new template. The resulting product is the Electronic Appraisal Reporting System (EARS). This report summarizes the work conducted under the implementation project.

Item 2 Field Test and Finite Element of I-345 Bridge in Dallas UNIVERSITY OF TEXAS AT AUSTIN. CENTER FOR TRANSPORTATION RESEARCH (CTR) CTR 4124-01-2 • 2009 This report documents a field test to determine the stresses at areas where fatigue cracks had formed in the bridges. Two bridges were instrumented and subjected to controlled truck traffic. In addition, the service fatigue stresses were evaluated by monitoring the stresses for a 1 week period after the controlled truck testing. A three dimensional finite element model was constructed of each bridge. The stresses from the field tests and the model were compared. The floor beams were found to behave as composite with the bridge deck when the truck loads were near floor beams. The local stress at the critical sections was in reasonable agreement between the field and analytical results. Proposed retrofit schemes were evaluated in the analytical model. In general, the proposed schemes appear to reduce the stresses at the critical locations, however high stresses are generated in other areas that have not cracked. The unsymmetrical support conditions of some of the girder units cause twisting of bridge section. Adding of additional supports to make the bridge support symmetrical will also improve fatigue performance of the bridge.

Research Digest Item 3 Development of the Texas Flexible Pavements Database : Implementation Steps for the Tour-based Model Design Option and the Data Needs UNIVERSITY OF TEXAS AT AUSTIN. CENTER FOR TRANSPORTATION RESEARCH (CTR) CTR 5513-2 • 2010 The goal of this research project was the development of the Texas Flexible Pavement Database (TFPD) to serve as a reference database comprising design, construction, structural and performance data for selected roadway sections in Texas. The database was designed as a project-level application with the purpose of developing, validating and calibrating mechanistic-empirical pavement design models. To achieve this objective it was necessary to evaluate pavement sections with performance data spanning a number of years and for this reason the database was initially populated with Texas sections from the Long Term Pavement Performance (LTPP) studies.

In addition, a number of newly constructed sections within Texas were included in the database. The performances of these new sections were monitored over a two-year period and performance data collected on these sections on two occasions have been included in the database. The TFPD comprises 70 sections (35 from LTPP and 35 new) spanning the climate, traffic, and structure types found in Texas. It is recommended that these sections continue to be monitored on an annual basis to track the performance of these pavements throughout their design life. It should be noted that the entire database consist of close to 200 sections, though few of them are missing information related to material properties and testing.

A second objective of this project was to provide guidelines for local calibration of the Mechanistic Empirical Pavement Design Guide (MEPDG). The performance models used in the MEPDG are calibrated using sections spread throughout the U.S. Hence, it is necessary to calibrate these models for specific states and regional conditions because of the differences in terms of materials, environmental conditions, and construction practices.

The regional calibration factors were obtained by minimizing the sum of squared errors between the observed and the predicted distresses. In this case, a simultaneous joint optimization routine was used because it is theoretically sound. Finally, an average of the regional calibration coefficients for AC and subgrade rutting was computed to obtain the set of state-default calibration coefficients for Texas. The report outlines the procedure followed and reports the initial local and statewide calibration factors determined based on the LTPP sections currently in the TFPD. 190pp.

Research Digest Item 4 Guidelines for Design and Safe Handling of Curved I-Shaped Steel Girders UNIVERSITY OF TEXAS AT AUSTIN. CENTER FOR TRANSPORTATION RESEARCH (CTR) CTR 5574-P1 • 2010 The purpose of this set of guidelines is to summarize recommendations from work completed as part of the Texas Department of Transportation (TxDOT) Research Project 0-5574 entitled “Curved Plate Girder Design for Safe and Economic Construction.” The research included field tests, three-dimensional finite element parametric studies, and software development. The full report for the study will be submitted by October 31, 2009 and includes a more detailed explanation of the recommendations given within this document.

The development of general guidelines to ensure girder stability during lifting, erection and early stages of construction is complicated by the wide range of variables that impact the behavior of the girder system. These variables include girder proportioning, partially installed bracing, crane positioning, the use and positioning of temporary supports, as well as several other factors. To aide in assuring girder stability, two analytical tools were developed as part of this research project. The analytical tools consist of a spreadsheet program (UT Lift) for evaluating girder behavior during lifting, and a finite element program (UT Bridge) for analyzing the behavior of I-girder bridges at various stages of erection and during construction of the concrete bridge deck. While the guidelines presented herein have been developed to assist in producing a stable system, the reader is encouraged to use the analytical tools, UT Lift and UT Bridge, or other suitable analytical packages, to evaluate bridge girder systems during construction. 13pp.

Item 5 Estimating Texas Motor Vehicle Operating Costs : Technical Report UNIVERSITY OF TEXAS AT AUSTIN. CENTER FOR TRANSPORTATION RESEARCH (CTR) CTR 5974-1 • 2009 A specific Vcost model was developed for Texas conditions based on a sophisticated fuel model for light duty vehicles, several excellent sources of secondary vehicle cost data, and the ability to measure heavy truck fuel consumption through both experimental and survey work. The basic model was designed to address the relatively narrow range of pavement roughness found on the Texas highway network and is free-flow, and does not accurately measure congestion effects. The team developed a vehicle classification scheme that was suitable for TxDOT planning and revenue forecasting. These resources led to the adoption of eight categories of light-duty vehicles and two heavy truck types. The current Texas fleet composition was determined from 2007 VTR data and was made a default for model use. Each cost item associated with the representative vehicle was calculated for each year of operation up to 20 years. Six main cost categories are included in the Vcost model: depreciation, financing, insurance, other fixed costs, repair and maintenance, and fuel. These costs fall into two categories: fixed and variable costs. The Vcost model can provide operating cost estimates for each specific representative vehicles as well as fleets of vehicles. The model allows the user to change key parameters so that the cost calculation is specific to any particular situation, and can be updated as the economic or technological landscape changes. The model was designed to provide the user with a program that looked, felt, and operated in a similar fashion to most Windows programs and would be intuitive for the typical TxDOT user. 230pp.

Item 7 Analysis of Large Truck Collisions with Bridge Piers. Phase 1 : Report of Guidelines for Designing Bridge Piers and Abutments for Vehicle Collisions TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 4973-1 • 2010 The American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications require that abutments and piers located within a distance of 30.0 ft of the edge of the roadway, or within a distance of 50.0 ft to the centerline of a railway track, shall be designed for an equivalent static force of 400 kip. Magnitude of the design force (400 kip) was established from data available at the time the LRFD specification was prepared. Supporting documentation for this design requirement, both its applicability and magnitude of the design force, was not extensive. Further detailed guidance for the design engineer is not available.

The objective of this research effort is to address the following questions: (1) What risks warrant application of this requirement? (2) Is the magnitude of design force (400 kip) appropriate? This is a report of work performed under Phase 1 of a multi-state pooled funds project entitled "Guidelines for Designing Bridge Piers and Abutments for Vehicle Collisions." 186pp.

Item 11 Balanced Mix Design Report for Lufkin's Crack Attenuating Mix (CAM) TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 5598-01-1 • 2010 Crack Attenuating Mix (CAM) designs are made according to the volumetric procedure defined in Special Specification 3109 (now 3165) where the optimal asphalt content (OAC) is computed as that which achieves 98 percent of the maximum density at 50 gyrations of Superpave Gyratory Compactor. Samples at the proposed OAC are then molded to 93 percent density and then subjected to performance testing in the Hamburg Wheel tracker and Overlay tester. A design was performed for the CAM mix to be placed on BUS 59 in Lufkin and using the specified procedure an optimum asphalt content of 8.3 percent PG76-22 was determined. This material was placed in the summer of 2008.

In this study an alternative mix design procedure was evaluated. In the balanced mix design procedure the performance tests are first run at several different asphalt contents, and an acceptable range of asphalt contents is identified where both the rutting and cracking criteria are met. An optimum asphalt content is then defined within the acceptable range, and volumetric checks are then made as the final step. Using this procedure the acceptable range of asphalt contents was defined to be between 7.0 and 8.0 percent (the upper limit tested in the balance mix design procedure). An optimum of 7.5 percent PG76-22 was proposed with the balanced mix design approach, substantially lower than that found with the current volumetric procedure. No acceptable design could be achieved with a PG70-22 binder. 14pp.

Research Digest Item 12 Guidelines for the Use of Pavement Marking Symbols at Freeway Interchanges : Final Report TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 5890-1 • 2010 Pavement marking technology has advanced to allow for the use of large multi-color symbols to be placed on the pavement as a means of providing drivers with another source of information from which they can make good driving decisions. This project focused on the use of such in-lane pavement markings to provide the driver with lane guidance and warning information near freeway interchanges. More specifically, researchers evaluated the design and application issues that are associated with the use of pavement marking symbols. The information gathered during this project was used to create a set of guidelines for the use of pavement marking symbols at freeway interchanges. 116pp.

Item 13 Potential Development of an Intercity Passenger Transit System in Texas : Final Project Report TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 5930-2 • 2010 This report describes the findings of a research study of the potential for development of an intercity rail and express bus system in the state of Texas. Rather than focus on regional commuter or light rail systems radiating from urban areas, this project examined long distance intercity and interregional corridors to determine which are most likely to need additional intercity travel capacity in the coming decades. Specific corridor characteristics for 18 intercity corridors were examined. Ranking of the corridors based upon these characteristics identify those that may need added intercity transit capacity in the future. The underlying analysis of corridors is based upon several factors related to: current and future population and demographic projections along 18 intercity corridors in the state; projected future demand based upon forecasts by the Texas State Demographer and other state agencies; and current transportation network capacity and routes for intercity highway, bus, air, and rail travel.

A preliminary concept plan was developed during the first year of the project, and the second year focused on determination of potential costs and benefits of implementing the concept plan or individual system components along each corridor. 208pp.

Research Digest Item 14 Video Library for Video Imaging Detection at Intersection Stop Lines TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 6030-P1 • 2010 The objective of this activity was to record video that could be used for controlled evaluation of video image vehicle detection system (VIVDS) products and software upgrades to existing products based on a list of conditions that might be difficult to find in a timely manner. This library allows the user to present a wide range of weather, roadway, and lighting conditions to a VIVDS product in real time. The idea involves capturing the video and playing the recorded video through a VIVDS processor to determine the accuracy or change in accuracy to compare against a test protocol and/or verify claims of manufacturers. The test conditions include situations that are not easily obtainable and that might be particularly challenging for current detectors.

This research task anticipates that TxDOT will encounter situations fairly often in which the desired conditions for full-scale field testing of VIVDS are not available or where quick turnaround tests are needed. There may be a need for a quick decision on a firmware upgrade or on a new product to establish at least an initial and preliminary basis for forming a decision on success or failure. There will probably be occasions where these initial results using the video library need to be verified by field testing if the desired conditions become available or if time and other resources allow such testing. TxDOT might want to establish a formal policy for the use of the library and conditions in which field testing might be desirable. [15]pp.

Item 15 Site Specific Wave Parameters for Texas Coastal Bridges : Final Report TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 6063-1 • 2010 There are about 20 coastal bridges located in hurricane evacuation routes in the State of Texas that are vulnerable to hurricane surge and wave action. Damage to these bridges could hamper emergency response and other services, and also cause tremendous economic loss. In recent devastating hurricane seasons of 2004, 2005, and 2008, several coastal highway bridges along the US coast of Gulf of Mexico suffered severe structural damages.

To prevent structural failure of coastal bridges, the magnitude of wave load on coastal bridges must be determined. The objective of this research is to determine site-specific design wave parameters (i.e., wave height and wave period) that are needed in computation of wave loads and evaluation of wave effects on coastal bridges.

In this project, we determined storm surge and wave parameters for four bridges using numerical models ADCIRC and SWAN. Simulation of water level including storm surge were performed with program ADCIRC, which also provides input to wave simulation. Wave parameters were determined by statistical analysis on simulation results performed with wave model SWAN at different storm surge and wind speed levels. Both wave and water level/storm surge simulations were vigorously validated with observed wave and water level data. The results of this research project will enable TxDOT to quickly implement the design methodology produced by an AASHTO/FHWA pooled fund study. 124pp.

Research Digest Item 16 Guidebook on Preserving and Enhancing the Functionality of Highways in Texas TEXAS DEPARTMENT OF TRANSPORTATION (TXDOT) TTI 6208-P1 • 2010 The purpose of this project was to identify the sources of deterioration of state highway functionality that occur over time and what actions can be taken to preserve, recover, and enhance functionality. Congestion and operational problems slow traffic, resulting in wasted fuel and time. Safety problems endanger goods and people and poor pavement can affect both travel speed and safety. In light of this, it is important that functionality be considered in all stages of a highway?s lifecycle and that it be protected, preserved, and where possible enhanced during the course of planning, growth and development, operations, and maintenance.

This report provides guidelines through an extensive list of actions for how TxDOT, MPOs, local jurisdictions, and other transportation stakeholders and agencies can protect, preserve, and enhance the functionality of the state highway system. It represents product P1 of TxDOT research project 0-6208, Preserving Functionality/Asset Value of the State Highway System. Relative to the full 0-6208-1 research report, this document is intended to serve as a reference document. 32pp.

Item 17 Integrating the Transportation System with a University Campus Transportation Master Plan : A Case Study TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 6608-2 • 2010 University campuses are considered major trip attractors. This intense level of activity generates significant congestion levels within the campuses and in their vicinity, particularly in urban campus settings. With university enrollment trends expected to increase substantially in the next decade, this problem can only be expected to become worse. In addition, university campus settings are multi-modal and complex in nature, incorporating vehicular traffic, transit, and pedestrians into one transportation system. This creates a significant challenge for university campus planners when trying to incorporate their campus master plan into the overall regional or metropolitan transportation system. Systematic approaches to planning for the interaction of the various transport modes (including auto, transit, bicycle, and pedestrians) within the university campus system, and for the integration of these different modes with the larger transportation system, have not been documented. The mix of concentrated levels of pedestrian and bicycle traffic with vehicular congestion in a campus setting creates a number of significant conflict areas that range from pedestrian and cyclist safety to traffic and transit operations.

These conflicts are exacerbated by the multijurisdictional nature of these interactions, which involve authorities at the campus, city, and state level. The objective of this research is to document a systematic approach to analyze the problems associated with the interaction and integration between university campus transportation systems and the larger metropolitan transportation system, in order to develop solutions to these problems. 138pp.

Research Digest Item 18 Integrating the Transportation System with a University Campus Transportation Master Plan : Best Practices and Lessons Learned TEXAS A&M UNIVERSITY. TEXAS TRANSPORTATION INSTITUTE (TTI) TTI 6608-3 • 2010 The University of Texas at El Paso (UTEP) is planning several projects that will have a substantial impact in the transportation network in El Paso. This research project conducted a study of the integration of the El Paso metropolitan transportation system with UTEP's transportation master plan and to develop a synthesis of best practices of transportation systems integration employed by universities from across the country. This research report presents a synthesis of these best practices and documents the lessons learned during the analysis of the UTEP campus found in Report 0-6608-2. The overall goal of the report was to provide guidance on the integration between transportation systems and a university campus master plan. Researchers used a two-pronged approach to document best practices in this report. First, researchers conducted a review of the state-of-thepractice on university campuses around the country. Second, researchers synthesized the lessons learned from the development of the case study analysis of the UTEP campus master plan and its integration with current and planned metropolitan transportation infrastructure, where the integrated application of practices from around the country could be tested. 24pp.
