4Question 4.
True or False: Travel times on all paths used in user equilibrium are equal.
- True
- False
Show hintHide hint
Consider how multiple routes are assessed.
Question 5.
Given a network with three paths and known travel times, derive expressions for flow that ensure user equilibrium.
Show hintHide hint
Focus on how each route contributes to overall travel.
Question 6.
Design a scenario where link capacities change. How does this impact your previous equilibrium calculations?
Show hintHide hint
Utilize key equations adjusted for new capacities.
