Adaptable Lighting

Lighting that learns the city

Cities are dynamic — traffic changes, weather shifts, and conditions evolve throughout the night. Yet most street lighting still runs on fixed schedules, creating a gap between planned lighting and what's actually happening on the ground.

Traffic and Weather Adaptable Lighting is designed to close that gap. It enables lighting levels to be dynamically adapted in response to changing traffic and weather conditions¹ — supporting visibility where and when it's needed, and dimming during lower-demand conditions to help reduce energy consumption compared with calendar-based operation.²

→ Are your streets lit for real-world conditions?

How it works

Adaptable lighting is powered by a rule-based system that uses traffic and weather data.¹

Data from traffic and weather sources informs the system
Predefined rules determine the appropriate lighting levels
Lighting profiles adjust automatically — enhancing existing dimming schedules without fully turning lights off¹

Example scenarios:

Lighting levels increase or are maintained during higher traffic or challenging weather conditions¹
Lighting dims during low-traffic, stable conditions — helping reduce energy consumption compared with calendar-based operation²

Work with your data - your way

Traffic and Weather Adaptable Lighting is designed to integrate with compatible smart streetlighting platforms and leverages compatible existing infrastructure — which may help reduce the need for replacement.

It works alongside your existing schedules, events, and rules, enhancing them rather than starting over.

Why it matters for cities?

Aligned with Real-World Conditions

Lighting strategies reflect how streets are actually used—rather than fixed assumptions.

Energy efficiency

Lights dim during lower-demand conditions, helping reduce energy consumption compared with calendar-based operation.²

Operational simplicity

Lighting profiles adjust automatically based on predefined rules — designed to reduce the need for manual intervention.

Future-ready infrastructure

Makes more of the streetlighting infrastructure you already have — designed with future smart city needs in mind.

Powered by Signify Interact

Interact enables cities and communities to manage street lighting through a powerful rule engine.

By integrating adaptable lighting:

Lighting levels are dynamically adjusted in response to changing traffic and weather conditions¹
Rules can be configured to match local priorities and policies
Cities can balance energy use, operational needs, and lighting requirements

Together, this supports a more responsive and scalable approach to urban lighting — designed to help cities progress toward their sustainability objectives.¹
