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.</p> <p><a target="_blank" href="https://blog.google/outreach-initiatives/sustainability/google-ai-reduce-greenhouse-emissions-project-greenlight/">Green Light </a><a target="_blank" href="https://blog.google/outreach-initiatives/sustainability/google-ai-reduce-greenhouse-emissions-project-greenlight/">uses AI</a> 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 13 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. </p> <p>Green Light reflects Google Research's commitment to use AI to address climate change and improve millions of lives in cities around the world.</p> </div> </div> </div> </div> <div class="_container_3mwgq_1"></div> <div id="how-it-works" class="_container_1xa7h_1"> <div class="_item_1xa7h_67" style="--grid-item-start: 2; --grid-item-end: 11;"> <div class="_container_1ntli_1"> <figure class="_frame_1wolg_15 _frameFullbleedMobile_1wolg_15"> <div class="_imageContainer_1wolg_10"><a class="_playVideoButton_1yq74_1" data-yt-modal-video-id="T6c_NdpbUvE?si=yucp8mkPUMxpzX6b" title="Play video" tabIndex="0"><svg width="49" height="48" viewBox="0 0 49 48" fill="none" xmlns="http://www.w3.org/2000/svg" role="presentation"> <g clip-path="url(#clip0_2785_5974)"> <path fill-rule="evenodd" clip-rule="evenodd" d="M43.6667 8.06667C45.808 8.58476 47.44 10.2427 47.9333 12.3333C49 16.1429 49 24.0667 49 24.0667C49 24.0667 49 31.9905 47.9333 35.8C47.44 37.8907 45.808 39.5486 43.6667 40.0667C40.1259 41.0967 26.0168 41.1321 25.5322 41.1333C25.515 41.1333 25.515 41.1333 25.5333 41.1333C25 41.1333 10 41.1333 6.33333 40.0667C4.192 39.5486 2.56 37.8907 2.06667 35.8C1 31.9905 1 24.0667 1 24.0667C1 24.0667 1 16.1429 2.06667 12.3333C2.56 10.2427 4.192 8.58476 6.33333 8.06667C10 7 25 7 25.5333 7C25.524 7 25.5195 7 25.5195 7.00001C25.5195 7.00032 40.0639 7.01859 43.6667 8.06667ZM19 17V31L32 24.5385L19 17Z" fill="white"></path> </g> <defs> <clipPath id="clip0_2785_5974"> <rect width="48" height="48" fill="white" transform="translate(0.5)"></rect> </clipPath> </defs> </svg><img src="https://lh3.googleusercontent.com/jyjL3SbrwV8nAOlaUl6c9uwa0ZcXuG4_52Aitv3gLCqR1KLnym6rJv0SKNdTtINMYlYeGQK0C2d9VIsgeSkO8ddw2Hj9qJHGihIz8avZ=w2880-e365-pa-nu" loading="lazy" alt /></a></div> </figure> <div class="_frame_13anx_99 _container_1r2da_1 _body_13anx_63 _bodyLarge_13anx_71"> <h3 size="3" class="_heading_1mjz1_1"> <div class="_frame_13anx_99 _heading3_13anx_32">How it works</div> </h3> <h4 size="4" class="_heading_1mjz1_1"> <div class="_frame_13anx_99 _heading4_13anx_47">1. Understanding the intersection</div> </h4> <p>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).</p> <h4 size="4" class="_heading_1mjz1_1"> <div class="_frame_13anx_99 _heading4_13anx_47">2.
