A 24-km-long metro circle line has 15 stations. The line operates with an average operating speed of 30 km/h and a headway of 4 minutes. The average standing time at each station is 60 s. a. By how much should the average standing time be reduced to allow the transit agency to reduce the number of TUs by two while keeping the same operating schedule? b. Considering the original condition, what is the required increase in the operating speed to reduce the headway to 3.5 minutes? c. Consider the line operates under the conditions of part a. Due to improvement in the line operations, the operating speed can be increased by 4 km/h over the speed under part a. Assuming the headway remains the same, compute the new operating speed, cycle time and number of TUs.

Question

A 24-km-long metro circle line has 15 stations. The line operates with an average operating speed
of 30 km/h and a headway of 4 minutes. The average standing time at each station is 60 s.
a. By how much should the average standing time be reduced to allow the transit agency to
reduce the number of TUs by two while keeping the same operating schedule?
b. Considering the original condition, what is the required increase in the operating speed to
reduce the headway to 3.5 minutes?
Consider the line operates under the conditions of part a. Due to improvement in the line
operations, the operating speed can be increased by 4 km/h over the speed under part a.
Assuming the headway remains the same, compute the new operating speed, cycle time
and number of TUs.
C.
