Designing and Implementing Advanced and Efficient Roadway Lighting

Last updated May 12, 2023

This 2016 paper by Adam Sedziwy and Leszek Kotulski is an essential for street lighting designers and engineers. The authors propose methodologies that drive savings by LED retrofit projects, advanced (aka Smart) lighting control and design, and operational & management cost savings available from advanced networked lighting systems.

This paper is ideal for lighting designers and city engineers responsible for implementing and managing advanced street lighting solutions. It addresses methods for optimizing the reduction of energy use and related GHG footprint, but also details out the cost of ownership and available savings from LED retrofit projects, the effective lighting design enabled by smart lighting controls.

Note however that this case does not address the operational and management cost savings

Key Findings

  • In the global perspective of electric energy usage, lighting’s share reaches 19% on a global scale and 50% on a Europe-only scale 
  • LED retrofitting enables the reduction of energy consumption by at least 40%
  • Advanced lighting controls can reduce baseline costs by 15%
  • Effective design of the lighting profiles by controls capable of optimizing in response to traffic and area conditions can reduce baseline costs by 15%

The presented case study shows that, thanks to applying the proposed method, one can design a lighting system which has the energy consumption reduced by up to 70%.

The baseline lighting costs from the study are based on HID lighting. For scenarios where the baseline costs are based on existing LED lighting, the available savings suggested by the study then become:

  • A 25% reduction in energy consumption from advanced lighting controls
  • A 25% reduction from effective design of the lighting profiles enabled by the advanced lighting controls

In this respect, we can see that it is reasonable to estimate the potential savings of adaptive dynamic lighting controls may be able to drive a savings of:

  • 30% of the total energy costs from an existing HID-based lighting system, independent from the 40% savings available from an LED retrofit
  • 50% of the total energy cost from an existing LED-based lighting system

It is important to note the distinction noted in this study that the savings from advanced lighting controls requires solutions that are capable of sensor connectivity that can dynamically monitor the ambient light and adapt to provide consistent illumination that avoids over-lit or under-lit roadways.

The Business Case for Smart Street Lighting as the Smart City Network

Owners and managers of street and area lighting need high quality, reliable information to support informed decisions about Smart Lighting and Smart City-related projects. Until now, most of this information has either been scattered across a vast number of academic studies, or websites with unsourced information and marketing-speak.

This article is intended to provide a supportable, accurate framework to help answer these questions:  “Why should our organization care about Smart Street Lighting? What do street lights have to do with our Smart City vision? “

The Health Effects of Light Pollution

A growing body of scientific research suggests that light pollution can have lasting adverse effects on human health, and wildlife health, habitat, and migration.

Factors Affecting Perceived Safety in Railway Stations

Feeling safe in public transport is essential for mobility, and fear of crime can be a larger problem for the individual than crime itself.

Among the most important characteristics affecting passengers’ safety are lighting, surveillance, other persons’ behaviour, time of day, and one’s own gender.

Creating safe spaces for railway and public transit facilitates increased use, which has follow-on socio-economic benefits for cities.
