Problem 1. Think about an individual that you are investigating from engineering analysis
perspective. A few years back, when he first visited DC, the price for a 7-day unlimited pass
MetroRail ticket was $10. Without knowing the spurt in rail ticket price, he moved to DC very
recently without purchasing a vehicle and planned to take Metro to museums and restaurants and
for commuting trips, too. Then, he found out the price for Metro tickets tripled. Use your
engineering knowledge to forecast or predict which of the following travel plan decisions would
change for this person? 1. The total number of trips made in DC; 2. The mode of transportation
he uses for travel; 3. Any other perspective of trips he makes. Can you also identify the possible
rationale behind all these changes? Problem 2. Name three simplifying assumptions that are used
in the mode choice and route choice steps. Pick one of them, and then explain how you could
change the procedure to relax this assumption and make the process more realistic.
Solution.
