Solar Power Street Lighting
Why use solar powered highway lighting when vehicles have headlights?
According to the Federal Highway Administration (FHA) Office of Safety, lighting on highways has benefits. It can significantly reduce pedestrian injuries, night-time crashes, and injury crashes on both rural and urban highways.
The FHA reports that the number of daytime and nighttime crashes are similar. The difference is that the number of fatal nighttime crashes is three times the number for daytime crashes. The reach of headlights is limited, and, on highways, cars are typically traveling faster at night. This gives drivers little time to react to pedestrians, changes in the road’s direction or other hazards.
Our transportation system is evolving to embrace public transportation as well as shared bicycle and pedestrian access. Solar powered road lights will become more important in the future.
Lighting to Meet Highway Standards
Fonroche’s application team is ready to provide design assistance to provide solar power street lighting that will meet recognized lighting guidelines. Configurations with break-away poles are available to avoid fixed-object crashes as well. Fonroche's Smartlight is the preferred solar lighting choice for DOT projects by multiple state departments of transportation, including Utah, Rhode Island, and New Hampshire.
In some areas light pollution is a concern. Fonroche will use fixtures with dark-sky certification and lighting shields to create your solar roadway lighting layout.
According to the Handbook of Road Safety Measures, highway lighting can reduce nighttime injury crashes on rural and urban highways by 28%.
Solar Lighting for Residential Streets
Increasing Safety with Solar Outdoor Street Lights
Lighting for Security
There is some debate about whether lighting directly impacts crime prevention. But most people agree that lighting can make people feel more secure.
Why does that matter? People venture out into the community because they feel more secure. They create what the law enforcement officials call “informal surveillance.” In civilian terms, "more eyes on the street".
The Department of Justice lays out additional ways that street lighting can reduce crime1.
In Darkness
- Lighting increases the risk that offenders will be seen and/or recognized. This acts as a deterrent.
- Police are more visible and offenders are less likely to act knowing they are there.
- If lighting helps in the arrest of offenders at nighttime, it can reduce daytime offenses too.
In Daylight
- An investment in improved lighting shows that the city government and police are focused on security. This changes the perception that the neighborhood is "easy pickings."
- A greater feeling of commuity pride and social connection can lead to a greater willingness to intervene in and report crimes.
- If offenders commit crime in both light and darkness, nighttime arrests and subsequent imprisonment would reduce both daytime and nighttime crime.
Mobility and Accessibility
It doesn't matter if you are lighting a cul-de-sac or a city street. Quality street lighting makes it safer and easier to navigate streets by foot, bike, or wheelchair. By providing lighting, you also extend the hours that residents can connect, play, and exercise outdoors.
What Can Solar Street Lights Mean for You? Confidence to take the bus to the grocery store? An hour at the playground with your kids after work? Visiting with neighbors after dinner? Or training for your next marathon in the pre-dawn hours?Â
Solar Lighting for Roundabouts and Intersections
Commercial Solar LED Street Lights are a fast and easy to implement way to improve safety at roundabouts and intersections. Per the FHA, lighting can reduce nighttime injury pedestrian crashes at intersections by 42%. Michael D. Rogers, of the Georgia Transportation Institute, researched crashes at roundabouts with and without lighting. He found that roundabouts with lighting experience about 60%-64% lower nighttime crash rates compared to unlit roundabouts.
Solar powered roundabout lighting can often overcome the cost and logistical barriers that leave some of these junctions unlit.
Solar powered street lighting provides an added safety benefit. Stand-alone solar lighting is capable of providing light during electrical power outages. This means intersections stay safe during evacuation and rescue activities.
Lighting Rural Intersections with Solar Power
The Insurance Institute for Highway Safety (IIHS) compares rural and urban crash fatalities. In 2020, crash deaths were much higher in rural areas per 100 million miles traveled than in urban areas (1.84 for rural areas and 1.08 for urban areas). Solar street lighting for intersections is especially important. A light pole at one of these locations can literally save a life.
Grid-connection at rural intersections is often expensive and difficult, including trenching or moving power lines. Autonomous solar lighting can be easily installed without any additional infrastructure.
