Select only the four correct answers. For the dissipation of queue, the average saturation flow should be smaller than arrival flow. Intergreen is the time duration from the end of green time of a particular phase to the beginning of green time for the other phase. Average saturation flow is smaller than saturation flow. Key tasks of traffic signal design involve phasing, red time allocating and green time allocating. Intergreen is the time duration from the end of green time of a particular phase to the beginning of green time for the same phase. For the dissipation of queue, the average saturation flow should be greater than arrival flow. Average saturation flow is greater than saturation flow. Key tasks of traffic signal design involve phasing, cycling and green time allocating.
