Problem 2: Travel Demand Modeling (80 pts) Consider a scenario in which the state department of transportation would like to forecast the travel demand in response to additional capacity on the turnpike, and determine how much traffic will shift from the nearby freeway to the turnpike after adding capacity on the turnpike. a. There are three options under consideration: adding one additional lane, improving interchanges to alleviate bottlenecks, or adding one additional lane and improving interchanges. All of them could improve travel time and shift travel demand from a nearby freeway to the turnpike. Either the stated preference survey or the revealed preference survey can be used for the travel demand forecast. Discuss why the stated preference survey is more appropriate for this application. (20 pts) b. In a stated preference survey, respondents are given multiple hypothetical scenarios to capture the effect of a specific attribute or characteristic of the given alternatives. Design three hypothetical scenarios to capture the effect of different toll rates. You may consider two alternatives: turnpike and freeway. Toll is one of the alternative specific attributes. Other alternative specific attributes include pavement quality (scale of 1-5, 5 is the best), travel time is another alternative specific attribute. Note: toll on the freeway is zero (60 pts) Problem 2: Travel Demand Modeling (80 pts) Consider a scenario in which the state department of transportation would like to forecast the travel demand in response to additional capacity on the turnpike, and determine how much traffic will shift from the nearby freeway to the turnpike after adding capacity on the turnpike. a.
