On an urban corridor regular bus transit is operated with headway of 10 minutes during peak hour. The reliability of transit arrival at a stop is observed 80%. If the seating capacity of a bus is 50 and load factor 1.5. Calculate vehicle capacity of transit. If 50% schedule operated during peak hour and double decker bus with seating capacity of 75 and load factor is 1.25, what will be the change in passenger capacity?
