      <title>A reinforcement learning approach to network-level maintenance planning of co-located road and water infrastructures with interdependencies</title>
      <link>https://trid.trb.org/View/2623421</link>
      <description><![CDATA[Due to co-location and spatial proximity, deteriorating transportation infrastructure (TI) and water infrastructure (WI) are geographically interdependent, exhibiting complex interactions both within and across systems. Failures from degradation or maintenance disruptions in one system can impair its own performance and cascade into the other. However, many existing studies address long-term maintenance only at the component, subsystem, or single-system level, without fully accounting for interdependencies both within and across co-located infrastructures. This paper proposes a network-wide joint long-term maintenance planning framework that integrates traffic and hydraulic simulations to capture interdependencies within and across multiple infrastructure systems. A reinforcement learning-based optimization model is formulated to minimize the expected cumulative costs of co-located TI and WI systems over a long-term planning horizon while accounting for future uncertainties in the deterioration of roads and pipes. The model jointly quantifies both short-term and long-term economic impacts of joint maintenance decisions at network level by comprehensively investigating diverse topological relationships and interactions between co-located roads and pipes. The framework is further validated through a realistic case study in Ybor City, Tampa, and benchmarked against alternative maintenance strategies, demonstrating cost savings achieved through proactive, coordinated decision-making across interdependent TI and WI systems.]]></description>

      <title>Data Driven Evaluation of the Transportation Barriers to Water Access on the Navajo Nation</title>
      <link>https://trid.trb.org/View/2652173</link>
      <description><![CDATA[ This project seeks to address water access challenges on the Navajo Nation by analyzing the intersection of transportation challenges, potential transportation risks, and related burdens faced by Diné (Navajo) households through the lens of obtaining water for household use. By leveraging data from the Diné Household Water Survey (DHWS), the project combines geospatial, economic, and water access data to explore the transportation barriers associated with hauling water and purchasing bottled water. The project aims to assess the impact of these barriers on public health, particularly in relation to vehicular accidents, financial costs, and access to safe drinking water in an analysis and evaluation using geospatial analysis, collected data from surveyed households (N=1,800), and existing transportation reports outlining the vehicular- and road-risks on the Navajo Nation. By mapping water hauling routes and analyzing road conditions, the project will identify high-risk areas for accidents, provide insights into transportation infrastructure needs, and estimate the financial burden of water hauling on Diné households. Additionally, this research will help inform the Navajo Nation's water delivery programs and transportation planning efforts, supporting sustainable improvements to water access. In relation to preserving the environment, this project examines how water hauling practices contribute to fuel consumption and road deterioration. By addressing the infrastructure and safety concerns of water hauling, this project aims to optimize resource utilization while promoting improved water accessibility and transportation safety, ultimately improving public health and well-being within the Diné community.  ]]></description>

      <title>Ontario Ministry of Transportation Stormwater Management Pond Sediment Beneficial Reuse Pilot Project</title>
      <link>https://trid.trb.org/View/2071853</link>
      <description><![CDATA[This Ontario Ministry of Transportation (MTO) stormwater management pond (SWM) sediment beneficial reuse pilot project demonstrated that asphalt contaminated sediment can be beneficially reused as a cost effective and environmentally sustainable alternative to landfill disposal. Thousands of engineered SWM ponds across Canada provide stormwater quantity and quality control for highways and urban centres. Overland runoff washes sediment and asphalt particle into SWM ponds, which accumulate in each basin over time. Environmental Compliance Approvals (ECAs) require routine sediment removal in order to maintain stormwater volume storage and quality treatment design requirements. Canadian federal and provincial legislation requires sediment chemistry analysis to identify waste disposal requirements. Dr. Francine Kelly-Hooper is running an ongoing 16-year Canada-wide study of sediment chemistry trends for over 200 SWM ponds. The growing database indicates that trace metals were generally low in 78% of the ponds. Sodium adsorption ratio (SAR) and electrical conductivity (EC) levels elevated in most ponds due to road salt and saline groundwater sources. However, road salt contaminated sediment can be a regulatory non-issue if a closed loop approach can reuse the sediment within roadside environments. 98% of SWM ponds in Ontario and 56% of SWM ponds located in other provinces would require landfill disposal due to elevated petroleum hydrocarbons (PHCs) and polyaromatic hydrocarbons from asphalt pavement sources. However, recycled asphalt is recognized as a valuable and inert resource by the Canadian paving industry and government regulators. This project was approved because the weight of research and forensics evidence supported a closed loop approach to the reuse of asphalt road runoff contaminated SWM pond sediment as roadside soil amendment materials.]]></description>

      <title>Rehabilitation of municipal infrastructure using risk-based performance</title>
      <link>https://trid.trb.org/View/1952902</link>
      <description><![CDATA[Municipal decision-makers struggle to reach effective solutions in asset management. The complexity of this issue increases when trying to consider more than one asset. This article proposes an approach that can optimize integrated decision-making for road, sewer, and water municipal assets. The proposed optimization is accomplished using risk assessment and a performance rating model. The model was tested on the infrastructure network of the city of Guelph and has resulted in a 36% risk dollar reduction under full integration. The model has also shown improved budget-savings when compared to the conventional silos approach. The findings aid municipal decision-makers in maximizing the benefits of their limited budgets, which will increase the number of infrastructure projects. Additionally, the results of the proposed model unveil more opportunities. Specifically, the use of more advanced computational methods along with exploring techniques that allow the user to consider multiple corridors within one repair scenario.]]></description>

      <title>Environmental assessment of a permeable pavement system used to harvest stormwater for non-potable water uses in a building</title>
      <link>https://trid.trb.org/View/1726458</link>
      <description><![CDATA[The objective of this work is to present and to apply a method to environmentally evaluate a permeable pavement system used to harvest stormwater for non-potable water uses in a building. Two pavement systems were compared through life cycle assessment (LCA). The first system consists of a permeable pavement; in this case, the stormwater filtered by the pavement is used for non-potable water purposes in a building. The second system consists of a flexible pavement (impermeable), with no stormwater harvesting, and with conventional water supply in the building. The method was applied in a case study in a public building in southern Brazil. Water consumption surveys were made and the potential for potable water and electricity savings in the building were estimated. In the inventory, input and output data related to each stage of the life cycle of the systems were gathered and quantified. In the impact assessment, it was found that, for both pavement systems, the most significant damages were related to the implementation and end-of-life stages. The permeable pavement system presented a lower potential for environmental impacts in most midpoint categories evaluated, and also lower overall potential impact in the endpoint approach. The results also showed that the categories with the greatest environmental impact for both systems were fine particulate matter formation and global warming. The method proposed can be used as a basis for guiding planning and decision-making to improve water infrastructure management through stormwater harvesting in urban centres.]]></description>

      <title>Tunneling under Howard County: Construction of a 36-Inch Water Transmission Main, Howard County, Maryland</title>
      <link>https://trid.trb.org/View/1639140</link>
      <description><![CDATA[As one of Maryland's fastest-growing regions, Howard County, a suburb of the Baltimore/Washington, DC, metropolitan area, has seen a 34 percent increase in population over the past decade. Projected population will grow to 328,000 by 2035. As a result, and as a means of improving reliability, the Howard County Department of Public Works completed a capital project to install 3.15 miles of 36-inch Diameter Water Transmission Main in the Columbia area. The water main alignment selected includes two crossings of U.S. Route 29, consisting of 1,225 feet of micro-tunneling, two river crossings, and what was considered the most challenging aspect of the project, installation of 7,500 feet of water main under one of the busiest roads in the region.]]></description>

      <title>Fill It Up—Getting Water to Port Miami in Time for Mega Cruise Ship Arrivals</title>
      <link>https://trid.trb.org/View/1639116</link>
      <description><![CDATA[Port Miami is one of the busiest cruise ship ports in the world, berthing larger cruise ships. Port Miami is facing water distribution system flow and pressure issues during cruise ship potable water filling activities.  In addition, Port Miami is preparing for the arrival of the largest mega cruise ships in the world, which will only worsen the water flow and pressure issues, if they are not addressed prior to their arrival. This paper will detail the planning work completed by the Miami-Dade Water and Sewer Department and the Miami-Dade Seaport Department.  In addition, it will review the subsequent activities to implement the planned water infrastructure and provide a status of the construction of the infrastructure and the arrival of the mega cruise ships. Hydraulic analyses were performed to identify transmission, distribution, and ship filling station improvements. Constructability was reviewed due to multiple ongoing construction projects as well as substantial subterranean structural components along the cruise ship wharf. This project included planning, utilizing one of the largest hydraulic models for one of the largest water systems in the U.S. It also included design coordination for various construction techniques, including microtunneling and horizontal directional drilling, due to a subaqueous crossing of Biscayne Bay, in Miami, Florida, and crossing of railways.]]></description>

      <title>Rehabilitation of a Critical High-Pressure Transmission Main underneath and in the Vicinity of a Major Highway</title>
      <link>https://trid.trb.org/View/1639101</link>
      <description><![CDATA[The joint transmission main (JTM) is part of the 38 mile long Joint Regional Water Supply System, operated and maintained by the South Coast Water District in California. The pipeline, made of 60 in. diameter PCCP manufactured in early 1960s, transports potable water to several service areas with limited redundancy. In 2010, the District started a condition assessment and repair program by performing an electromagnetic (EM) inspection of a 3 mile long section, of which a 1.5 mile long section was re-inspected in 2016. The EM inspections identified seven distressed pipes, one underneath a major highway (SR 133) with 19 ft of soil cover, one underneath the shoulder of the highway, two in the vicinity of the highway adjacent to a major new development, and three others in difficult to access wooded areas. The distressed pipes have a design working pressure of 150 psi to 200 psi and operate at pressures close to design. Considering high consequence of failure, the distressed pipe under the highway was repaired proactively using carbon fiber reinforced polymer (CFRP) liner in Phase 1 of the project. Phase 2 was performed on two pipes to verify the EM results by external inspection, reevaluate failure risk, and perform external post-tensioning repairs if necessary in the same shutdown. External inspections indicated that the EM inspection had significantly overestimated the number of wire breaks, and repair of the two investigated pipes was not necessary at this time. While the district and its consultants spent significant effort in planning and execution of Phase 2, the results proved such efforts worthwhile by avoiding unnecessary repairs and providing valuable information for planning of future inspections and repairs of the JTM. This paper presents planning and execution of both phases of the project from both the district’s and the consultant’s perspectives.]]></description>

      <title>Opportunistic Pipeline Condition Assessment: More Bang for Your Capital Buck!</title>
      <link>https://trid.trb.org/View/1639095</link>
      <description><![CDATA[The city of Virginia Beach made a proactive decision to evaluate the condition of existing subsurface utilities in coordination with an upcoming roadway improvements project along a well-travelled corridor within Virginia Beach. Approximately 5,111 linear feet of 20-inch cast iron water main was inspected using pipeline condition assessment (p-CAT). The collected condition assessment data was utilized to develop a risk profile for the entire length of the tested pipeline based on a comparison between the original and remaining wall thicknesses. This data ultimately allowed for DPU staff to prioritize various sections of the water main within the anticipated envelope of roadway improvements. The higher priority subsections were located outside of these limits eliminating the need for rehabilitation prior to the planned roadway construction. The opportunistic condition assessment performed allowed for the city to gain a robust understanding of specific logistics and/or lessons learned for deploying p-CAT and/or similar technologies.]]></description>

      <title>Not Everything Is Broken: The Future of U.S. Transportation and Water Infrastructure Funding and Finance</title>
      <link>https://trid.trb.org/View/1490904</link>
      <description><![CDATA[This report examines current U.S. policy related to transportation and water infrastructure funding, finance, and project selection and suggests possible improvements to modernize federal policies. It examines trends in public and private-sector spending; finance mechanisms currently in use; federal policy and impact on infrastructure investment; and policy options. It finds that U.S. infrastructure is not in as dire a state as sometimes reported. In general, public spending on infrastructure has been stable since 1956 with State and local governments stepping in when federal spending declined. However, serious problems do exist and recommendations to maintain stable financing for infrastructure include: tax exempt and taxable bonds, sustainable revenues, targeting long-term projects, focusing on capital investment, prioritizing maintenance of federal assets, making resilience to natural disasters a condition for spending, improving efficiency, and funding technological innovations.]]></description>
