Abstract A real-time, on-line control algorithm is proposed that aims to maintain the adaptive functionality of actuated controllers while improving the performance of traffic-actuated signal control system. To be consistent with the operation logic of existing signal control devices, only those four basic control parameters that can be found in modern actuated controllers are considered: phase sequence, minimum green, unit extension and maximum green. Microscopic simulation is used to test and evaluate the proposed control algorithm comparing with free-mode actuated, actuated-coordinated and volume–density control in a calibrated signalized network. Simulation results indicate that the proposed algorithm has the potential to improve the performance of the network at different traffic demand levels.
