1. Define the following concepts:a) Spacing between TUs (Transit Unit)b) Frequency of servicec) Vehicle productivityd) Consumption ratee) Way capacityf) Moving blockg) Transit line capacityh) Average speed on a transit networki) Operating personnel utilization factor2. A metro line operates during peak hours with six-car trains at three-min headways and carries 14,800 prs/h on its maximum load section. The capacity of each car is Cv = 180 sps/veh. The minimum headway that can be maintained on an open line between stations with the existing block signals at present operating speed is 40 s, while the longest minimum headway at a station is 105 s. Compute:a) Scheduled capacity of the line, Co’b) Maximum load factor αmax at presentc) Way capacity if the line Cwd) Vehicle line capacity, ce) Maximum offered line capacity, Cf) Maximum load factor αmax if the line operates at its offered line capacity and itspassenger volume increases by 20% over the present volumeI need a clear hand writing (not pretty) and all the steps how the problems are solve.
