Summer 2024’s record heat creates problems for transportation infrastructure, from roads to rails. When temperatures rise, rails expand due to the heat. This expansion can create high pressure and tension within the rail material. Combined with the forces exerted by moving trains, this pressure can cause the tracks to buckle to the side and become misaligned. It is sometimes referred to as a “sun kink.” Designing for resiliency is becoming the primary imperative in how we build and upgrade of critical infrastructure. https://bityl.co/Rpo8

Arlington, TX / August 5, 2024 / The Conversation US / Suyun Paul Ham — The record-breaking heat of summer 2024 is wreaking havoc on America’s aging #infrastructure, with #transportation systems across the country struggling to cope. Incidents like New York's Third Avenue Bridge being stuck open due to metal expansion and #roads buckling in states like #Washington and #Wisconsin highlight the growing challenges posed by extreme temperatures. Amtrak has also warned passengers of potential heat-related disruptions, with risks to power lines and rails causing significant delays. This heat wave is exacerbating existing issues within the U.S. infrastructure, which the American Society of Civil Engineers rated a C- in its latest report. Despite some improvements, much of the nation's infrastructure, including bridges and roads, remains in poor or mediocre condition, with rising maintenance costs further complicating efforts to keep the system operational.

Honored to contribute to a story by NBC News covering the impact of the latest #heatwave on NJ transit. Here are a few highlights on the effects of #heatwaves on the rail transportation system: * Heatwaves cause steel rails to expand, leading to track misalignment or buckling, increasing derailment risks. * Overhead catenary wires can sag in the heat, becoming entangled with railcar equipment and causing disruptions. * This requires more frequent inspections and reduced train speeds, which can lead to service delays. * As #climatechange results in more frequent and prolonged #heatwaves, we may see more delays in transportation systems affecting commuters.

What is tunnel convergence and how will implementing a monitoring regime prevent potential disaster? 👇👇 Tunnel convergence monitoring is crucial in identifying any deformation within a tunnel's structure. Caused by ground displacement or material failure, construction activities can often exacerbate these issues. Early detection is key for prompt repairs and avoiding potential disruptions. As part of our monitoring services, our team can install and monitor sensors to ensure any structural issues are identified, and safely addressed.

Check out our latest article, “Emergency Management Plan for Electric Vehicles During Floods Using Daily Routing Patterns”, published in the 2024 IEEE International Conference on Smart Mobility. This paper provides a framework for #prioritizing #EV_routes and the corresponding #EV_charging_locations during floods. *Should we target highly serviced EV trips? *What if EV usage data at the charging locations is not easily accessible? *Should we aim for a high prevalence of charging locations on EV trip routes? *Is “prevalence” enough? The findings of this paper aim to support policymakers in: 1) Planning alternative EV charging locations during emergencies. 2) Developing rerouting plans for EVs while ensuring sufficient mobility requirements are available. I would like to thank my supervisors, Dr. mohamed zaki and Prof. Ashraf El Damatty for their insightful guidance and support.

When we say we need a lot more transmission lines to connect and deliver clean power, we mean a LOT. The U.S. needs to build or upgrade around 75,000 miles of transmission lines to meet our climate goals – the equivalent of building *30 transmission lines connecting Los Angeles to New York City.* Finding faster ways to build transmission where it causes the least impact to communities and the environment – like using existing routes for highways and railroads – is going to be key.

Rail & Climate Change: CP7. With our infrastructure battered by 14 unprecedented named storms last year and forecasts of the same or worse, Network Rail has released it's next 5 year plan to invest to better protect our railways. £2.8bn has been committed to activities and technology to help our infrastructure cope with extreme weather, thus delivering a more reliable and better performing railway for both Passengers and Freight. Examples include: - More than 600,000 meters of drains will be built, rebuilt, redesigned or see increased maintenance to enable our railway to cope with much heavier rainfall and reduce flooding. - Targeting over 20,000 cuttings or embankments for attention, with over 300 miles being strengthened through renewal and refurbishment and over 900 miles seeing planned maintenance. - Recruiting almost 400 drainage engineers who will increase the care and maintenance of assets to be able to better handle increased and intense rainfall. - Installing significantly more ‘smart’ movement sensors to cuttings and embankments giving early warning of any changes enabling engineers to react, hopefully before a full landslip. - Installing CCTV at high-risk flooding sites to enable better and faster response. Amongst much more... The investment has already begun, will you be a part of it's journey? #EnvironmentalManagement #CP7 #Infrastructure #ClimateChange

Updating Intensity-Duration-Frequency (IDF) curves is crucial for designing resilient stormwater networks, especially in light of evolving climate patterns. With climate change, rainfall patterns have shifted, impacting both the frequency and intensity of rainfall events. Consequently, relying on outdated IDF curves for design purposes can yield unreliable outcomes, potentially jeopardizing infrastructure and safety. Regular monitoring and analysis of rainfall data are essential to accurately capture these changes and inform future design decisions. By incorporating updated IDF curves into design processes, engineers can ensure that stormwater networks are equipped to withstand the increasingly variable and intense precipitation events expected in the future. Updating IDF curves involves assessing historical rainfall data and utilizing advanced modeling techniques to predict future precipitation patterns. By aligning design storms with the most current IDF curves, engineers can mitigate risks associated with climate change, enhance the resilience of stormwater infrastructure, and safeguard communities against the impacts of extreme weather events. In summary, prioritizing the update of IDF curves is imperative for developing robust stormwater management strategies that can effectively adapt to changing climate conditions and ensure the reliability and longevity of infrastructure projects. #StormwaterManagement #ClimateChange #InfrastructureDesign
