Every day, road workers operate just feet away from live traffic, facing risks from speeding, distracted, and impaired drivers. In this episode of Unboxed: The SRF Podcast, host Nick Busse sits down with Jon Jackels (SRF Consulting), Reed Leidle (Safety Signs), and Brady Markell (Street Smart Rental) to discuss how portable traffic control signals are transforming work zone safety.

The conversation explores why many projects still rely on traditional flagging operations, despite the availability of proven technology that can reduce worker exposure, improve traffic flow, lower costs, and increase project efficiency. The panel discusses real-world deployments, barriers to adoption, misconceptions about temporary traffic signals, and why designers, agencies, and contractors should consider these systems earlier in project planning.

Topics include:

• Work zone safety challenges
• Portable traffic control signals
• Flagger safety and worker exposure
• Mental health impacts on field crews
• Connected work zone technology
• Real-time signal monitoring and remote management
• Construction staging and traffic control design
• Future integration with connected vehicles and navigation systems

If you're involved in transportation engineering, construction, traffic control, or roadway safety, this episode offers practical insights into a technology that could make work zones safer for both workers and the traveling public.

At SRF, we are dedicated to creating lasting solutions that strengthen our communities. However, many of the areas we serve face significant challenges, none more pressing than the issue of homelessness. In this episode of Unboxed: The SRF Podcast, we dive into how community partnerships and innovative housing models are making a measurable difference.

Our host, Nick Busse, sits down with Todd Polum, President and CEO of SRF Consulting Group, and Kelly Matter, President and CEO of Avivo.

In this episode of Unboxed: The SRF Podcast, host Nick Busse sits down with Cassie Champion (Metropolitan Council) and Abby Moore (Mississippi Watershed Management Organization) to discuss Sacred Water Shared Future. This regional campaign commemorates a century of restoration efforts on the Mississippi River in the Twin Cities.

In 1926, the river was so polluted that a survey found only three living fish in a 42-mile stretch. Today, we explore the engineering marvels, public policy shifts, and community stories that transformed an "ecological disaster" back into a thriving resource.

In this episode, we discuss:

• The harrowing state of the river in the 1920s and 30s.
• The construction of the Metro Water Resource Recovery Facility, the first treatment plant on the Mississippi.
• Modern challenges like microplastics, phosphorus, and chloride.
• How a bass drum auctioned by the band Semisonic helped kickstart the campaign’s branding.
