So in the case of multiple intersections, there are a few differences: after the delay time was calculated by the algorithm in single intersection model, NeverStop will not set up the delay time immediately. Instead, it asks for the information about the neighbor intersections from the central server. When the data was received by the EBox, NeverStop can get a micro adjustment according to the fuzzy control, and then get the accurate time that the current phase should delay. For example, if the neighbor intersection is in heavy jam, the delay time of current phase should be shorter. On the contrary, if the neighbor intersections have no congestion, the time of green light can be increased accordingly. Fig. 6 describes the relations between the classes.
