About Infrastructure Insights: Engineering Explained
Infrastructure Insights features casual conversations (and some geeking out) about the infrastructure supporting the world around us. Our innovative problem solvers are engineers, geologists and environmental scientists who are passionate about creating a better tomorrow. On Infrastructure Insights, we will share stories, best practices, and trends that span the world and range from complex technical topics to the latest developments in technology applications. Get ready to geek out with us.
Ep 36: The Roundabout Debate: Capacity, Comfort and Safety for All Users
Roundabouts are often praised for improving traffic flow, reducing severe crashes and enhancing roadway safety. But as communities invest more in active transportation, accessibility and multimodal transportation networks, questions remain about how roundabouts serve people walking, biking, rolling and navigating with disabilities. Are roundabouts truly safer for everyone, or does their success depend on how they are designed?
In this episode, B&N roundabout expert Brian Walsh and active transportation expert Amy Rosepiler explore the balance between traffic operations, pedestrian and bicycle safety, accessibility, and user comfort. Together, they examine the perception that roundabouts are "good for cars but bad for bikes and pedestrians" and discuss how features like raised crosswalks, rapid-flashing beacons (RRFBs), pedestrian hybrid beacons (PHBs), separated bike treatments and lower-speed design can help create safer, more inclusive transportation systems without sacrificing performance.

Ep 35: Alternative Delivery: Approaches From Across the Country
Alternative delivery methods like design-build, progressive design-build and CMGC are becoming more common across the country, but this shift isn’t happening by accident. Owners are under increasing pressure to deliver projects faster, manage risk earlier and provide greater cost certainty, all while projects grow more complex.
In this episode, we're joined by B&N’s Kevin Jasinski, John Kilgore and Steven Bronzell to explore what’s driving the rise of alternative delivery methods, from funding challenges and accelerated timelines to evolving risk and the need for stronger collaboration. We also discuss what this shift means for different types of owners, from those just getting started to more experienced agencies, and what separates teams that succeed from those that struggle.

Ep 34: Simulation Analysis: Testing Pedestrian Safety Before It Hits the Street
On this episode of Infrastructure Insights, we’re joined by Ethan Meszaros to explore how traffic simulation models serve as a practical, decision support tool for evaluating pedestrian crossing treatments in complex, multimodal environments. Ethan walks us through how simulation can be used to test real-world questions — such as how a crossing treatment may affect pedestrian delay, vehicle operations, safety tradeoffs or interactions between different modes — before changes are implemented in the field.
We also talk about what makes traffic simulations useful: clear assumptions, careful calibration, and a model that reflects how people actually move through a corridor or intersection. And for cities and agencies with limited time or resources, Ethan shares how traffic modeling does not have to be an all-or-nothing effort. When used selectively, it can support phased implementation, compare practical alternatives, and help teams focus on their investment where it adds the most value.
