The prodyn real time traffic algorithm
Webb1 apr. 1983 · PRODYN is an algorithm able to compute in real time the best signal settings with respect to the delay criterion for any flow demand in traffic networks. The hierarchical algorithm uses Forward Dynamic Programming (FDP) to compute controls at the lower level (intersections) and decomposition coordination technics at the upper level. Webb22 juli 2024 · PRODYN [ 11] is a decentralized and adaptive system developed by CERT in France. It is used to optimize online traffic by using a dynamic program to minimize delays at intersections by relying on a model of traffic flow over the entire horizon. Its system allows communication with a neighbor intersection in order to anticipate the incoming …
