Introduction Interchange in Public Transport • Some challenges and respective needs: – Low competitiveness

Introduction Interchange in Public Transport • Some challenges and respective needs: – Low competitiveness in relation to the car • The need to reduce operational cost – New requirements within the context of demand for higher sustainability in urban mobility • The need to increase patronage • Aim of this research: – Evaluate the potential of interchange of enhancing Public Transport Network efficiency Introduction Methodology Model Operational Cost Service Level Case Study Results Conclusions • Increase patronage without increasing cost 2 Tredbo 9.

Metodology Interchange in Public Transport • Construction of a model – Study the potential

Metodology Interchange in Public Transport • Construction of a model – Study the potential optimization of the use of transport resource without service change, and – Study the potential service enhancement without extra cost • Case Study (STCP) – Evaluate the potential effect on demand Introduction Methodology Model Operational Cost Service Level Case Study Results Conclusions 3 Tredbo 9.

Model Interchange in Public Transport Introduction Methodology Costumer Network Without Interchange With Interchange Network

Model Interchange in Public Transport Introduction Methodology Costumer Network Without Interchange With Interchange Network length / Nº of vehicles / Model Operational Cost Headway - -- Frequency + ++ Distance + 0 ou + Waiting time at origin - -- Total waiting time + - Service Level Case Study Results Conclusions Note: the signs represent the variation for each variables with the introduction of interchange for the 3 and 4 nodes model (Scenario 1, N=constant). 4 Tredbo 9.

Operational Cost Interchange in Public Transport • Optimization of the necessary transport resources (maintain

Operational Cost Interchange in Public Transport • Optimization of the necessary transport resources (maintain service level): – Reduction of the number of necessary vehicles – Potential reduction of route length – Reduction of the number of routes for the same network Introduction Methodology Model Operational Cost Service Level Case Study Results Conclusions 5 Tredbo 9.

Service Level Interchange in Public Transport • Potential Improvements: – Higher frequencies (lower headways)

Service Level Interchange in Public Transport • Potential Improvements: – Higher frequencies (lower headways) – Network enlargement – Enhanced reliability Introduction Methodology Model Operational Cost • Potential Deteriorations: Service Level – Interchange / Uncertainty – Increase of travel distance Case Study Results Conclusions 6 Tredbo 9.

Results Interchange in Public Transport • Estimated effect on demand: – Potential increase •

Results Interchange in Public Transport • Estimated effect on demand: – Potential increase • Decrease of passengers having to interchange (<< then expected) • Increase of other passengers Introduction Methodology Model Operational Cost Service Level Case Study Results Conclusions 8 Tredbo 9.

Conclusions Interchange in Public Transport • Interchange has the potential of: Introduction – Optimizing

Conclusions Interchange in Public Transport • Interchange has the potential of: Introduction – Optimizing transport resources – Increasing transport service without extra cost Methodology Model – Increasing Patronage without extra cost Operational Cost • Key issue of interchange for PT patronage Service Level – For interchange to foster patronage it must introduce sufficient optimization of necessary transport resources granting enough network efficiency gains to compensate inconvenience of interchange without Case Study Results Conclusions extra cost. 9 Tredbo 9.
