Dynamic Metering in Connected Urban Street Networks: Improving Mobility

As traffic congestion increases on urban street networks, a network’s ability to process vehicles decreases because of queue spillovers and gridlock. Traffic metering can help regulate the flow of vehicles entering congested areas to allow the network to operate at its optimum level. This study sought to develop a traffic metering method for urban street networks and to study the effects of metering on traffic operations.
