Find the total hourly volume, flow rate and PHF. Time 7:30-7:40 7:40-7:50 7:50-8:00 8:00-8:10 8:10-8:20 8:20-8:30 Volume 250 280 300 200 150 130A 14-km streetcar line travels eastbound and westbound in shared ROW, and in each direction, it has stops every 250 m. Because the line is heavily used, it has a headway of 2.5 min and streetcars stop at each service stop. The running speed of streetcars between stops is 25 km/h (not accounting for stopping at stops). At each stop, streetcars spend 30 sec in acceleration, deceleration and dwell time. The terminal time is 10 min/terminal. The line is being redesigned into a high-quality streetcar line. The new streetcars have double the capacity of existing cars, and the headway of the new line will be increased to 5 min (although some passenger trips might be lost due to the increased stop spacing and increased headway, the travel demand is expected to be at least the same because of the overall performance improvement of the line). Two options are being considered: Option 1: The new stop spacing is 300m. The new line is expected to have a running speed of 40 km/h and the stop time…
