We measure how many stops we’ve saved for drivers, and its impact on traffic patterns. We then use industry standards models to calculate the climate impact of these changes. We share this with the partner city and continue monitoring for any future needed changes.

Building on our decades-long effort to map cities across the world, we can infer existing traffic light parameters including: cycle length, transition time, green split (i.e. right-of-way time and order), coordination and sensor operation (actuation).

What isbacklight in photography

Green Light only shares recommendations about how a city should optimize traffic light timing - for example if they should add additional seconds of “green time” to a particular part of the traffic light cycle. User data is never shared with the city or any other third party.Â

Backlight, or back lighting, is any light source that comes from behind your subject. However, backlighting is a more general term, and can be used to describe a broad range of lighting from rim light to a “kicker” light. Whether it is technically correct or not to use the term backlight to describe any and every form of lighting that comes from behind is not as important as simply understanding what another photographer is referring to.

No. Our system offers better plans based on aggregated anonymous data to improve traffic flow for everyone: Google and non Google users, car drivers, taxi drivers, buses and all other users of the road.

Once a city signs an agreement with Green Light, they get access to our interface, where city officials can view suggested recommendations, supporting information, and monitor their measured impact on emissions and traffic flow.

In post-production, dealing with backlighting can be difficult, if your subject is in deep shadow, however both silhouette images and brightly exposed images can work, if the editing fits the mood of the scene, pose, etc.

Lighting design

When we start working with a city, the Green Light algorithm investigates driving patterns through the city, uses insights from Google Maps, and provides recommendations for intersections to optimize, based on the expected impact of the optimization. For example, if a traffic light at a certain intersection is already on the best possible plan, the system would not provide a recommendation for it.

Backlight can definitely come from any light source, including the sun on a bright day, or a wireless flash on a dark night.

Green Light algorithms will continue to monitor all relevant metrics, and two weeks after implementation a full impact analysis report will be uploaded to the interface for city engineers to review.

Since the actual technique is relatively simple, these tips are going to help you think creatively to get the most out of what is otherwise known as a silhouette. In the first example, when faced with a rather mundane hotel room, we first imagined what the room would look like underexposed, and then set our ambient exposure to the desired settings to create a backlit photo using this screen door. You can see the full tutorial on how we arrived at the final image on the right in Photographing the Couple.

Silhouettes are much more interesting when the subjects are placed against the brightest portion of the scene. If that doesn’t exist, then create a highlight with your backlight. If you are using your backlight to bring light into a darker part of the scene like the sample above, then find a unique composition that draws the attention to that point like we did with this mural.

The goal of backlighting, from an artistic and technical standpoint, is usually to help separate a subject from a background, and bring emphasis to that subject in dark conditions, having a backlight can be especially helpful, and sometimes it can actually serve as the ONLY major light source in a dramatic silhouette photo.

No, all recommendations are based on driving trends from Google Maps and are then implemented by the city using the city’s existing systems and equipment.

When faced with challenging scenes or short on time, pulling out a pocket strobe and placing it behind our subjects creates something pretty spectacular.  Here are a the steps to using a flash as a backlight for impactful Images

We create a model to understand how traffic flows through the intersection. This helps us understand typical traffic patterns including patterns of starting and stopping, average wait times at a traffic light, coordination between adjacent intersections (or lack thereof), and how traffic light plans change throughout the day.

We are currently in the early research phase and offering Green Light to partner cities at no cost. Our primary goal of this product is to support cities’ sustainability goals.

Color: Will it be gelled for creative or corrective effect? Depending on your in-camera white balance setting, you can gel your flash to match your existing light or work against it.

Green Light uses AI and Google Maps driving trends, with one of the strongest understandings of global road networks, to model traffic patterns and build intelligent recommendations for city traffic engineers to optimize traffic flow. Early numbers indicate a potential for up to 30% reduction in stops and 10% reduction in greenhouse gas emissions (1). By optimizing each intersection, and coordinating between adjacent intersections, we can create waves of green lights and help cities further reduce stop-and-go traffic. Green Light is now live in over 70 intersections in 14 cities, 4 continents, from Haifa, Israel to Bangalore, India to Hamburg, Germany – and in these intersections we are able to save fuel and lower emissions for up to 30M car rides monthly.Â

Power: How strong will your light source be? You can zoom your strobe to use the light as a bounce/fill or you can power up to create flare lines.

The Green Light dashboard provides city-specific actionable recommendations, showing supporting trends for each recommendation, with the option to accept or reject the suggestion. After a recommendation has been implemented, the dashboard shows an impact analysis report.

Using AI, we identify possible adjustments to traffic light timing. We share these adjustments as actionable recommendations with the city. The city’s traffic engineers review the recommendations, approve them, and they can easily implement them in as little as 5 minutes, using the city's existing policies and tools.

Road transportation is responsible for a significant amount of global and urban greenhouse gas emissions. It is especially problematic at city intersections where pollution can be 29 times higher than on open roads.  At intersections, half of these emissions come from traffic accelerating after stopping. While some amount of stop-and-go traffic is unavoidable, part of it is preventable through the optimization of traffic light timing configurations. To improve traffic light timing, cities need to either install costly hardware or run manual vehicle counts; both of these solutions are expensive and don’t provide all the necessary information.
