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.

Benchmarks for vehicle delay performance include Webster's optimized fixed-time control, vehicle-actuated control, and an adaptive fixed-time policy derived from SCOOT.
Webb1 jan. 1987 · PRODYN is a real time method for finding the optimal settings on an urban network. Its basic characteristic is the use of dynamic programming for intersection optimization. In that paper, we investigate and compare two main directions for the control of a network : hierarchical control and decentralized control. curly bob hairstyles for womenWebbThe maximum total delay time decreases from 96.15 h to 83.77 h, as low as 12.9%.
