10. Curitiba: Desire vs. Reality
Goal:
Cover the entire city with a subway system
Goal:
Could only afford single LRT line
Design “surface subway” system using buses to get network up and running
Problem:
Solution:

11. Curitiba: Transit/Land Use
Goal:
Ensure land uses support transit investments.
Goal:
Viability of transit depends on density.
Require virtually all density to be located within one block of mainline corridors.
Problem:
Solution:

12. Curitiba: Buses and Roads
Goal:
Make buses run faster.
Buses always get stuck in traffic.
Create bus-only “roads within roads,” with traffic signal priority, both reducing running time and making the system more reliable.
Problem:
Solution:

21. Curitiba—Speedy Network
Goal:
Reduce transit trip times.
Longer trips involve many stops.
Create an overlay network of “speedy” buses directly linking major transfer centers and demand generators, thereby cutting 30 minutes off average trip.
Problem:
Solution:

23. Curitiba—Implementation
Goal:
Problem:
Extend “rapid” transit services as quick as possible
Goal:
Need to keep capital costs low
Bus-based system “colonizing” existing rights-of-way has led to extra-ordinarily rapid system expansion
Problem:
Solution: 74 79 84
Solution: 89 94 97

24. Curitiba—Increasing Capacity
Goal:
Increase bus capacity. Buses can’t compete capacity-wise with rail.
Have Volvo build 260-passenger double-articulated buses.
Problem:
Solution:
