This presentation, presented by Jeremy Stretz, aims to provide an accessible introduction to the principles, standards, and technologies that guide modern roadway and intersection lighting. The presentation covers foundational lighting terminology and design principles. It explains how industry standards like IES RP‑8 shape design decisions, highlights key fixture and light‑source characteristics, and walks through the general design process for roadway, intersection, and pedestrian lighting. Practical examples using photometric software demonstrate how these concepts are applied in real‑world scenarios, offering attendees a clear understanding of both the science and practice of effective street lighting design.
