Benefits of Roadway Lighting

When: June 26, 2025 | 3:00 -- 4:00 PM ET

This webinar is led by the ITE Traffic Engineering Council.

Webinar Description:

This presentation aims to equip traffic engineers with actionable knowledge regarding roadway lighting, ultimately contributing to enhanced safety and operational efficiency. We will delve into the primary applications of roadway lighting, exploring how strategic illumination can mitigate risks at intersections, along high-speed corridors, and in pedestrian zones. Furthermore, the session will offer a comparative analysis of various lighting technologies, ranging from traditional high-intensity discharge lamps to modern, energy-efficient LED systems. This will empower engineers to make informed decisions based on performance, cost-effectiveness, and environmental impact.

Beyond applications and technology, a significant portion of this presentation will focus on essential design considerations. We will examine critical factors such as light levels, uniformity ratios, glare control, and pole placement, all of which play a vital role in creating safe and comfortable driving conditions. Moreover, we will discuss relevant standards and guidelines, ensuring that engineers are well-versed in best practices for roadway lighting design and implementation. By addressing these key areas, this presentation seeks to provide traffic engineers with the practical tools and understanding necessary to optimize roadway illumination for the benefit of all road users.

Learning Objectives:

• Explain how effective roadway lighting contributes to reducing nighttime crashes and improving pedestrian visibility.
• Identify and recommend appropriate lighting strategies for different roadway environments, including intersections, highways, and urban streets.
• Compare the energy efficiency, performance, and longevity of common lighting technologies such as LED, High-Pressure Sodium (HPS), and others.
• Apply best practices for achieving optimal lighting levels, uniformity, and glare control, including appropriate pole placement, to ensure safe and effective roadway illumination.
• Interpret and apply Illuminating Engineering Society (IES) standards to guide the design and evaluation of roadway lighting systems.
