It’s been two years since Google first debuted<\/a> Project Green Light<\/a>, a novel means of addressing the street-level pollution caused by vehicles idling at stop lights. At its Sustainability \u201823 event on Tuesday, the company discussed some of the early findings from that program and announced another wave of expansions for it.<\/p>\n

Green Light uses machine learning systems to comb through Maps data to calculate the amount of traffic congestion present at a given light, as well as the average wait times of vehicles stopped there. That information is then used to train AI models that can autonomously optimize the traffic timing at that intersection, reducing idle times as well as the amount of braking and accelerating vehicles have to do there. It’s all part of Google’s goal to help its partners collectively reduce their carbon emissions by a gigaton by 2030.<\/p>\n

When the program was first announced in 2021, it had only been pilot tested in four intersections in Israel in partnership with the Israel National Roads Company but Google had reportedly observed<\/a> a “10 to 20 percent reduction in fuel and intersection delay time” during those tests. The pilot program has grown since then, spreading to a dozen partner cities around the world, including Rio de Janeiro, Brazil; Manchester, England and Jakarta, Indonesia.<\/p>\n

\u201cToday we’re happy to share that\u2026 we plan to scale to more cities in 2024,\u201d Yael Maguire, Google VP of Geo Sustainability, told reporters during a pre-brief event last week. \u201cEarly numbers indicate a potential for us to see a 30 percent reduction in stops. We believe green light is unique because it is more scalable and cost effective for cities than alternative options.\u201d Ideally, cities would deploy the models across grids of neighborhood blocks to create \u201cwaves\u201d of propagating green lights.<\/p>\n

\u201cOur AI recommendations work with existing infrastructure and traffic systems,\u201d Maguire continued. \u201cCity engineers are able to monitor the impact and see results within weeks.\u201d Maguire also noted that the Manchester test reportedly saw improvements to emission levels and air quality rise by as much as 18 percent. The company also touted the efficacy of its Maps routing in reducing emissions, with Maguire pointing out at it had “helped prevent more than 2.4 million metric tons of carbon emissions \u2014 the equivalent of taking about 500,000 fuel-based cars off the road for an entire year.”<\/p>\n
