You should evaluate the p and consider possible improvements. resent system headways independently for routes acd and bc. Compute the resulting systemwide TC (total cost) and I (load factor). b. Optimize the system with the same headway for both routes. Assume on-time arrivals at transfer station c. Find new coordinated h* (headway) and TC c. Divide route acd into two routes ac and cd. Optimize a coordinated headway h and find TC d. Design a single route to serve all 4 stations. Find h* and TC. e. Are there any other routing and/or scheduling alternatives you want to evaluate? What would you recommend?

Explanation / Answer

Two routes acd and bc: Total passengers 230 passengers/ hour from table

a) Total Cost=230*10=2300

load factor=230/50=4.6
