Department of Transportation A3 - United States. Department of Transportation. Federal Highway Administration AB - In 1993 and 1994, the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) initiated regulations that radically altered practices in the paint industry. Many of these measures apply to lead abatement, practices devised to eradicate lead-based paint hazards. These changes in legislation are designed to promote domestic, worker and environmental safety. The organizations that must implement these changes are finding that complying with the new rules are complicated and extremely expensive. The Oklahoma Department of Transportation (ODOT) selected seven bridges to overcoat with coating systems that meet the new standards for evaluation. The systems selected require minimal surface preparation, that is, removal of loose debris and dirt instead of the removal of an existing paint system on the steel beams, prior to application. Research, Development and Technology Transfer of ODOT monitored the application of several different paints to these bridges. An eighth bridge was cleaned using an abrasive cleaning method then coated with a lead-based paint that no longer meets the new regulations; this will be the control bridge for this study. This construction report presents the observations and application procedures of these coating systems to the above-mentioned bridges with emphasis on compatibility testing, SSPC SP2, SSPC SP3 and SSPC SP6 standard cleaning methods, construction procedures, and cost analysis.

A2 - University of Oklahoma A3 - Oklahoma. Department of Transportation AB - Urban areas considering major transportation investments evaluate alternatives using various techniques such as benefit-cost analysis and cost effectiveness measures. A comprehensive benefit-cost analysis is the least biased method of judging project merit when cross-modal impacts are significant. Using Oklahoma City data, five build alternatives in two corridors were examined using three different evaluation methodologies: (1) user benefit analysis, described in a 1977 American Association of State Highway and Transportation Officials manual; (2) cost effectiveness, which employs the Federal Transit Administration's average cost per new transit rider index; and (3) benefit-cost analysis, developed specifically for this study. The alternatives included light rail transit and high occupancy vehicle lanes. The study illustrates how benefit cost analysis can incorporate important cross-modal interactions by distinguishing between passenger and commercial traffic, and trip purposes and vehicle types. The study demonstrates several innovative methodologies including procedures for calculating user benefits when the travel forecasting model uses a fixed trip table, estimating congestion relief to highway modes resulting from transit investments, and incorporating non-user costs such as air quality, noise, and parking subsidies. When properly applied, benefit-cost analysis reveals important transfer payments which are not apparent from other, more aggregate, evaluation techniques. A major finding is that the overall quality of an investment study is heavily dependent on the travel modeling procedures.

TY - Tech Report AU - Lampert, David AU - Ahmadvand, Maryam A2 - Oklahoma State University. School of Civil & Environmental Engineering A3 - Oklahoma Department of Highways AB - Construction projects typically require mass clearing and grading, causing many site areas to be unstable. As a result, they lack ground cover to protect against rainfall and runoff, which results in soil degradation and erosion. Erosion introduces nonpoint source suspended solids pollution (NPS) into water bodies that diminish water quality and reduce the lifetime of water resources. In the past few years, there has been a significant improvement in water quality by using erosion and sedimentation best management practices (BMPs). Due to the complexity of the sources of pollution caused by NPS, many challenges remain. Desirable environmental protection and appropriate drainage and erosion control are only achieved when drainage, erosion, and sediment control (ESC) work together. However, proper implementation of construction site erosion and sedimentation BMPs and post-construction maintenance minimize alterations in water quality throughout construction. Most construction storm water violations are the result of lack of properly implemented BMPs.

Federal Highway Administration AB - The Oklahoma Department of Transportation (ODOT) Research and Development Division (R&D) installed field data acquisition systems in 1992 on five test pavement sections with a view to evaluate the performance of the drainable base and edge drain systems in Oklahoma. Rainfall, outflow and other data have been collected continuously since that time. The University of Oklahoma (OU), in association with ODOT, analyzed the field data, developed appropriate computer programs (written in SAS 6.08 language) to analyze the data, developed a simple, quick and efficient field test scheme to evaluate the drainage efficiency of the existing pavement sections, and conducted a number of field tests for this purpose. This report presents the results of these studies. The useful data, containing rainfall values and the corresponding outflow values reflecting the drainage characteristics of the pavement drainage system. were identified and grouped into a number of "events." The events were studied to establish any relationship between outflow and rainfall magnitudes, flow rates, time required to initiate flow in different types of pavements, and time required for drainage. This information was combined to determine the drainage efficiency of the corresponding drainable base and edge drain system. Finally, the time for 50% drainage was computed and compared with the AASHTO guidelines to determine the drainage quality of the pavements under investigation. This report presents the steps involved in grouping, analyzing and interpreting the field data, and explains the findings with appropriate textual and graphical illustrations. A field test procedure was developed to facilitate a quick examination of the quality of a pavement drainage system. The procedure for this field test, results of the field tests performed, and a comparison with regular rainfall and outflow data are also presented in this report.

State of practice research highlights the reasons why this lack of participation in the workforce occurs. Fortunately, there are also identified strategies for alleviating the workforce challenges. This report highlights measures that transportation organizations can take to combat some of the workforce challenges they are facing. When organizations are willing to have candid conversations and invest in meaningful policies, this can accelerate a shift in the trust and culture within an industry, making that industry more attractive to the talent pool that exists. Beyond the extensive literature review, this report describes the findings from an industry survey. The survey was distributed for a three-month data collection period, which concluded in July 2024, resulting in 996 usable survey responses. Additionally, the research team interviewed 15 transportation professionals in 2024 to gain deeper insights into the challenges and solutions to the workforce participation in the transportation industry.

Milkweeds are weedy plants that frequently occur along roadsides, and they are the only food used by caterpillars of the monarch butterfly, whose populations have sharply declined in recent years. Conservation actions aimed at stabilizing populations of the monarch must thus identify the locations of milkweed plants. We conducted a pilot study using drones flown over three milkweed populations and determined that an artificial intelligence model aimed at identifying objects successfully identified individuals of two species of Western milkweed, although different methods were needed to identify flowering plants, whose nectar is needed by adult monarchs. This study also revealed that the abundance of narrowleaf milkweed predicts monarch presence. We conducted another study using images from the NDoT Roadviewer database and again successfully used object-based artificial intelligence to identify milkweed occurrence along Nevada roadways. It was, in general, easier to identify showy milkweed, which has a more distinctive architecture, than narrowleaf milkweed. Both studies revealed the importance of study timing relative to the life cycle of the milkweeds and monarchs.

The methodology involved expanding and annotating two large-scale image datasets, each containing more than 6,000 self-collected images. Faded pavement markings were classified into white and yellow categories, while roadside litter was divided into four classes: white litter, black litter, leaves, and dirt. Two deep learning detection models were trained using the You Only Look Once (YOLO) architecture. In addition to object detection, researchers developed a counting algorithm to quantify the number of detected objects within roadway segments or video clips. A geolocation model was also created by integrating GPS data through time-based interpolation, achieving precise spatial localization of detected assets. Finally, an interactive visualization interface was implemented using the Folium Python library to display the georeferenced inspection results, enabling intuitive mapping and data-driven asset management.

A2 - Texas A&M University System. Texas Transportation Institute A3 - Texas Department of Transportation. Research and Technology Implementation Office A3 - United States. Department of Transportation. Federal Highway Administration AB - Historically, pedestrian signal heads have been internally illuminated using incandescent lamps. However, with the current widespread use of light emitting diodes (LEDs) in pedestrian signal heads, concerns regarding the visibility of LED devices have emerged. Research was needed to develop measurable visibility performance requirements for pedestrian signal heads, as well as test methods to verify compliance with these requirements. Researchers solicited expert opinions concerning the minimum luminance necessary for the daytime recognition of the walking person and upraised hand indications. The findings indicated that the minimum luminance values proposed by the Institute of Transportation Engineers (ITE) (5300 cd/sq m and 3750 cd/sq m) should provide an adequate level of brightness for daytime recognition of the walking person and upraised hand indications, respectively. Through a nighttime discomfort glare study, researchers determined the median glare threshold for the walking person and upraised hand indications to be approximately 3100 cd/sq m and 2600 cd/sq m, respectively. Since these values are less than the minimum luminance levels proposed by ITE, researchers recommended that pedestrian signals be dimmed at night. In addition, the discomfort glare study findings indicated that the ITE minimum dimmed luminance requirement (i.e., 30% of the minimum luminance values) will provide an adequate level of brightness for nighttime recognition of the walking person and upraised hand indications. Researchers also evaluated two test methods by which to measure the luminance of pedestrian signal indications. The ITE proposed test method measures the luminance of a pedestrian signal indication at nine separate points on the indication's surface, while the full indication method measures the luminance of an entire indication in one measurement. Researchers recommended the use of the full indication test method to verify compliance with the recommended visibility performance requirements.

This project implemented the TRPS mode at four locations in Texas using customized versions of the guidelines developed in research project 0-4421. Customization of the guidelines was necessary to account for the differences in certain site characteristics (e.g., available system detectors) between the implementation sites and the general site for which the original guidelines were developed. Locations were selected to represent a range of traffic conditions, arterial and detector configurations, and the two common controller types (Eagle and Naztec) used by TxDOT. The performance of the TRPS mode was evaluated by a comparison of average instantaneous and link speeds and delays determined before and after the implementation of the traffic responsive control. The before-after analyses indicated that the performance of the TRPS mode was in most cases better or at least as good as the existing systems. A step-by-step field manual to guide field technicians through the process of configuring their controllers to run a TRPS control was also developed and delivered to TxDOT to facilitate the implementation of the TRPS guidelines.

Federal Highway Administration AB - Texas Department of Transportation (TxDOT) research project 0-4421 "A Simplified Approach for Selecting Optimal Traffic Responsive Control Parameters" developed a novel scientific and computationally based procedure and guidelines for operating coordinated systems with traffic responsive plan selection (TRPS) mode. Since its development in the 1970s, TRPS mode remained an underutilized resource due to the complexity of its configuration. Numerous parameters (i.e., detector weights, thresholds, timing plan look-up tables, TRPS timing plans, etc.) had to be set up correctly for the system to work as intended. As a result, traffic engineers have typically preferred to use the time-of-day mode of operation for its ease of setup. This project will implement the guidelines developed in research project 0-4421 and document a before and after comparison summary for five locations in Texas. Locations are to be chosen to represent a wide range of traffic and/or arterial configurations. This progress report documents the efforts thus far for fiscal year 2005.

Our previous MPC-funded project (Report No. MPC-668) demonstrated the strong potential of using artificial intelligence (AI) and mobile phone imagery to identify various transportation assets. However, that initial effort was limited in scale, using only ~1,000 images for training and validation. Building upon this foundation, the present project focuses on two targeted assets: pavement marking issues and roadside litter, while expanding the capability of the previously developed AI packages. In this study, the dataset increases to over6,000 images for each asset type. Using the You Only Look Once (YOLO) deep learning architecture, two detection models are trained and achieved strong accuracy metrics, with F1-scores of 0.88 for pavement marking issues and0.84 for roadside litter. In addition, counting and geolocation models are developed to quantify detected objects within a road section or video clip and to determine their precise locations by integrating data from a phone-based Global Positioning System (GPS) tracker. The geolocation model demonstrates high spatial accuracy, achieving an average positional error of only 0.27 meters. To facilitate practical application, an interactive mapping interface is implemented to visualize the geolocation, object class, inspection time, and cropped image of each identified object. This interface enables clear and intuitive assessment of pavement conditions, specifically faded markings and roadside litter. Overall, this project enhances our prior work by extending capabilities in detection, counting, geolocation, and visualization, which supports regular asset inspection, informs maintenance planning, and ultimately improves roadway safety.

Bumblebee species have complex life histories, interacting with different obligatory habitat requirements across the ontogeny of the colony. Transportation corridors present unique opportunities for interventions to configure the quality and spatial configuration of local bumblebee habitats. We identify the particular vulnerabilities of an RPBB colony in each life history stage and how avoidance, minimization, and mitigation actions can be designed at each stage to meet project-specific objectives. We offer suggested mitigation actions that target specific objectives in the U.S. Fish and Wildlife Service’s “Species Recovery Plan for Rusty Patched Bumblebee.” Finally, we identify information gaps that could be filled with targeted scientific research to answer questions relevant to the management of bumblebees in transportation corridors.

A significant barrier to research on police traffic enforcement has been the lack of a detailed and comprehensive database. California’s Racial and Identity Profiling Act (RIPA) confidential dataset offers an unparalleled resource to address this gap. This report documents the process undertaken as the first external researchers to access and process the confidential RIPA data. Information is provided on the rigorous process required to access the data, including extensive documentation of information technology security. Details are provided on the methodology to process, clean, standardize, and restructure the large dataset into a stop-person analytic file for use in traffic safety research. Descriptive findings from over 17 million traffic stops (2018-2023) reveal key characteristics of enforcement patterns but also highlight data quality challenges and limitations, such as ambiguities in determining the travel mode for nearly 40% of individuals stopped. Despite substantial administrative and technical hurdles, the confidential RIPA dataset is an indispensable tool for traffic safety research. Forthcoming mandated improvements to data collection, combined with the data processing framework presented here, will enhance the dataset’s utility for traffic safety researchers.
