This paper compares the operation of a decentralized Nash bargaining traffic signal controller (DNB) to the operation of state-of-the-art adaptive and gating traffic signal control. Perimeter control (gating). based on the network fundamental diagram (NFD). was applied on the borders of a protected urban network (PN) to prevent and/or disperse traffic congestion. https://mabelandfoxs.shop/product-category/building-blocks/
