The transportation sector poses a formidable challenge for decarbonization due to its sheer diversity and scale. Among the potential solutions, eco-driving through semi-autonomous vehicles offers an emerging opportunity to mitigate carbon emissions. By programming vehicles to reduce stop-and-go traffic using intelligent speed adjustments, significant reductions in emissions can be achieved. A comprehensive study explored the effects of eco-driving across a wide variety of traffic scenarios, employing advanced modeling techniques, including large-scale scenario analysis and multi-task deep rein…
