Abstract
A method and system are provided for modeling and optimizing the performance of transportation networks, e.g. for traffic signal retiming. The modeling and optimization may be implemented by obtaining a video signal from a camera at a first intersection; processing data from the video signal to determine at least one value indicative of a corresponding traffic flow through the first intersection; sending the at least one value to a remote processing entity via a wireless network to enable the remote processing entity to update a model of the transportation network, the transportation network comprising the first intersection and at least a second intersection; receiving from the remote processing entity, an instruction for a controller at the first intersection, the instruction having been determined from an update of the model based on data from at least the second intersection; and having the instruction implemented by the controller at the first intersection to optimize at least a portion of the transportation network.
