    Eco-friendly Cooperative Traffic Optimization at Signalized Intersections
    Hao, Peng ;
    Oswald, David
    2023-02-01 | PDF
    Surface transportation systems (e.g., arterial roadways with signalized intersections) are inherently inefficient, particularly at higher traffic volumes. In general, both the infrastructure (e.g., traffic signals) and the vehicles operate independently, with little coordination between them. Previous research has shown that implementing strategies ...
