An apparatus and system for monitoring and managing traffic flow. The system includes a plurality of remote sensor devices arranged in a plurality of vehicles, a plurality of remote communication hub devices operatively arranged along one or more roadways and in communication with the plurality of remote sensor devices, a central server, a network interface in communication with the central server and the plurality of remote communication hub devices over a network, and a shared database in communication with the central server. The central server is configured to receive traffic data from the plurality of remote sensor devices over the network, update traffic data in the shared database, periodically calculate an optimal traffic flow for one or more of vehicles traveling along the one or more roadways based on the updated traffic data, and transmit timing adjustments over the network to one or more traffic light intersections based on the optimal traffic flow calculations. The network interface is configured to send and receive traffic data. The traffic data includes vehicle location information and network traffic congestion information.
