Lightning Quiz – Lecture 16

1. The arrival of buses at a stop follows a Poisson process with a mean inter-arrival time of 15 minutes. If a user misses her bus by 5 minutes, how long will she have to wait for the next bus?

• (a) 15 mins

• (b) 10 mins

• (c) Anywhere between 5 to 10 mins

• (d) Cannot be determined based on the information provided

2. A bus route experiences 5 delays per week on average due to traffic congestion. What can the Poisson distribution help estimate?

• (a) The probability of experiencing exactly 3 delays in a given week

• (b) The times when delays will occur

• (c) The specific bus stops where delays will occur

• (d) All of the above

3. A major airline schedules only 30 minutes for boarding and deplaning at each gate during peak hours, but the actual process takes an hour. What type of congestion is most likely to occur in this scenario?

• (a) Vehicle-facility congestion

• (b) Vehicle-schedule congestion

• (c) Load-vehicle congestion

• (d) Load-schedule congestion

4. On January 7, 2025, a wildfire near Los Angeles led to sudden traffic disruptions, causing severe congestion on I-405 and surrounding roadways. This is an example of:

• (a) Load-dependent congestion

• (b) Recurrent congestion

• (c) Non-recurrent congestion

• (d) Both (a) and (c)

5. To model peak-period congestion on an urban corridor with signalized intersections, frequent lane changes, and heavy pedestrian crossings, an analyst should use:

• (a) Volume-delay curve

• (b) Traffic simulation

• (c) Queuing theory
