The example presented is quite simple and works properly. At this time, you may want to consider altering the model and its parameters to study the effects. The following suggestions are made:
● Add the capability for a policeman to manually change the traffic lights in time of heavy traffic or an accident. This may be accomplished by changing the label on theN_S.GREEN_LIGHT to
N_S.YELLOW_LIGHT
transition to:tm(en(N_S.GREEN_LIGHT),N_S_GREEN_TIME) or SWITCH
whereSWITCH
is an event generated by the policeman.
● Note that during the malfunction, all lights begin flashing immediately. During this period, no time advances. And when the lights are repaired, the lights return to their default configuration. You may want to change the model to reflect more realistic traffic situations.
● These traffic lights perform the same cycle 24 hours a day. At night, it might be unrealistic to have the same light delays as appear during daylight hours.
