In contrast to the conventional single-channel detection which uses all the detectors across all the lanes as a single input to a signal phase, the lane-by-lane detection monitors the gaps/headways on a lane-by-lane basis. In the conventional actuated control detection, detectors transmitted information to the signal control machine as long as they were triggered, but signal control machine can not distinguish which lane are they from. In the lane-by-lane detection proposed in this paper, detectors of each lane worked independently and transmitted information of each lane to the signal control machine separately. Based on the probability theory, models were derived for estimating the green extensions with various geometric configurations. Using the proposed models, green extensions for actuated signal controls can be obtained. By comparing the required green extensions of buses and social vehicles to determine whether to give priority to the bus signal. The lane-by-lane control strategy proposed in this paper were simulated by VISSIM. The simulation results showed that the lane-by-lane control strategy has a better control effect in different situations compared with the fixed time control strategy and conventional actuated control strategy.
