Dr. Y-J Lee TRSP307-04-092817 ASSIGNMENT #3 (Due: October 5, 2017) 1. Assuming that there are two terminals, A and B, and their P-MAKE functions are shown in the below figure. Service headways (intervals) of those terminals are 12 hours and 24 hours, respectively. Draw yard time curves for each terminal. f(AVAIL) 1 B A 0 hr 2 hr 4 hr 6 hr 8 hr 10 hr 12 hr 14 hr AVAIL (15) 2. Assuming that there is a rail line consisting of two intermediate terminals, B and C. The information of the operation at those terminals are shown in the below figure. A C B 12 hours 12 hours AVAIL = 10hrs f(AVAIL) = 0.7 D 12 hours AVAIL = 10hrs f(AVAIL) = 0.7 Interval: 24 hours First compute the expected the current Origin-Destination trip time and then compare with the 4 different improvement plans shown below. a) Compute the expected O-D trip time with improved in-transit trip time, 10 hour. b) Compute the expected O-D trip time with improved f(avail) value, 0.9. c) Compute the expected O-D trip time with improved service headway, 12 hours. d) Compute the expected O-D trip time with bypassing the terminal B.
