Ensuring Safe and Efficient Railroad Crossings

Railroad intersections are an essential component of a transportation network as they facilitate the movement of goods and passengers. However, they pose a significant safety risk if not properly designed and maintained. This is where engineering for railroad intersections comes into play. Engineering services for railroad intersections involve the design, construction, maintenance, and inspection of…

The Transformative Power of Transit

Transit systems play an important role in connecting individuals who lack access to personal vehicles or the ability to drive to employment, healthcare, and recreational opportunities. Access to reliable transit systems is deeply personal to me. One of my earliest memories was running with my mother (more like my mother dragging me) at a Milwaukee,…

Becoming a Drone Pilot

I recently became a licensed drone pilot after our team realized we had an opportunity to enhance our ability to gather information for traffic projects, whether through obtaining a more comprehensive understanding of the existing conditions within a project area or enhancing our deliverables to clients. Drone Use in Engineering While not all engineering projects…

Leveraging Vissim Modeling

Vissim modeling allows individuals to map various intelligent traffic management systems to stabilize traffic flow and increase traffic safety. Vissim is a microsimulation tool that models individual vehicles in the traffic stream, considering the actions of virtual drivers in response to other vehicles, the road network, and various traffic controls. Sain Associates built a Vissim…

Which Came First – Utilities or the Roadway?

When you’re looking at designing (or redesigning) a roadway, you need to think first about the impact that project will have on the utilities surrounding the road. If you don’t, you’ll likely find yourself grinding to a halt when you encounter a utilities-related roadblock in your next project. Utilities are the lines, wires, and pipes…

Transportation Funding 101

Formula and grant funding play a crucial role in the civil engineering industry, allowing for the development of innovative projects that improve infrastructure and support sustainable growth. Without these public funding sources, many engineering projects would not be possible. While infrastructure funding has typically been legislated on a formula basis, in recent years, we have…

10 Years of APPLE

What does a fruit have to do with engineering? Well, in this case, it’s one of the first steps in the preliminary engineering process. The Advanced Planning, Programming, and Logical Engineering (APPLE) program is administered by the Regional Planning Commission of Greater Birmingham (RPCGB). The goal of the program is to assist local governments in…

Why is it Important to Proactively Prevent Wrong-Way Driving?

In 2022, the United States Department of Transportation adopted a Safe System Approach as the guiding paradigm to address roadway safety. It recognizes that people make mistakes, and the road system should be designed to forgive those mistakes. This is especially true for wrong-way driving prevention – we must do something before people drive the…

Strategic Crash Mitigation – A Low-Cost Approach

A few weeks ago, I was traveling out of state to meet my newborn niece for the first time. My wife and I encountered many rural roadways that needed some TLC along the way. To my wife’s amusement, my engineer’s brain could not stop noticing all the deficiencies of the roadways. Abrupt curves with no…
