9.8. Problems

Try these first

1. 1.

   Define modal split in your own words.

   Hint

   Think about the different types of transport modes in your city.

2. 2.

   What is the purpose of the binary logit model?

   Hint

   Consider how we use probability in decision-making.

3. 3.

   What does modal split refer to?

   • Distribution of trips among transport modes
   • Total number of cars on the road
   • Percentage of public transport users

   Hint

   Think about how different modes of transport are used by the public.

4. 4.

   True or False: The binary logit model can only consider two alternatives.

   • True
   • False

   Hint

   Remember, it's about breaking down choices.

5. 5.

   Given the costs derived as follows (Car: 5.5, Bus: 3.5, Train: 2.5), how would the introduction of a new electric bike service priced at 1.5 affect the existing modal split? Calculate the new probabilities.

   Hint

   Use the logit model to include the new mode.

6. 6.

   Use the previous data of 4200 trips and recalibrate if the bus fares increase by 1. How does it change the trip distribution?

   Hint

   Remember to update the logit calculation with the new bus cost.
