1. A diagnosis system for an adaptive signal control system in a network, said system comprising: a processor; and a memory, the memory storing instructions to cause the processor to: estimate a traffic state by identifying a relationship between real time data feed from a plurality of sensors and a control strategy of said adaptive signal control system; store a probability that a supply-demand mismatch of the traffic state will propagate from a first sensor to a second sensor; and train the control strategy of the adaptive signal control system to adjust signal control actions to reduce the probability that the supply-demand mismatch will propagate from the first sensor to the second sensor.
