Problem 2: minimum cycle length and the
effective green time for each phase
An intersection has a three-phase signal with the
movements allowed in each phase and
corresponding analysis and saturation flow rates
shown in the following table. Calculate the sum of
the flow ratios for the critical lane groups.
