    1. 1. Integrated Public Transport System SITP- BogotáJuan Pablo Bocarejo, PhDDirector Grupo de Estudios en sostenibilidad urbana y regional -SUR
    2. 2. Overview1. SITP2. Where are we now3. Expected impacts4. Main challenges
    3. 3. 1. SITP• An integrated system including Transmilenio network (28% share) and buses in mixed traffic (72%)• A centralized regulation (Transmilenio S.A)• Contracts with strong bus companies• Integrated fare system• ITS for operation optimization• Investment in terminals• A mixed retribution system to operators
    4. 4. 2. Where are we now• Operation concessions awarded to 9 companies• Technology concession awarded• Gradual and “calm” Implementation• Institutional strengthening• Financing and investments by private companies
    5. 5. 3. Expected impacts Assessing local impactsSITP Zones PM10 Concentration 5

Expected impactsTransportation Air Quality Exposure Energy model Noise model model Model model Vehicle Modal VSP emissions Buit volumes distribution environment Emission factor by type of vehicle PM2.5 per link Modal Consumption Local distribution factors emissions Global emissions Noise level Available Concentration Speed Concentration technology of PM2.5 model
    7. 7. 3. Expected Impacts• Operation – Transmilenio Phase 3 – Decrease in bus fleet – Efficiency and offer better adapted to demand – Bus stops Average travel time per trip -12% In vehicle travel time -18% Waiting /transfer time 25%
    8. 8. 3. Expected Impacts• Air quality – Euro IV buses replace 15 year old average – 5000 old buses scrapped – Ecodriving – Phase 3 Transmilenio

    20. 20. 4. Challenges• A poor negotiation done by a Mayor in Disgrace – Compensation to previous operators – 24 year concession• Improving Environmental performance• Infrastructure investment included in the concession contract to be paid by fares?• Danger of loss of accessibility, impact on equity issues• Subsidies policy• Some high demand corridors need prepaid stations, priorities, exclusive bus lanes…• Transmilenio S.A. institutional capacity must be doubled• Demand overcomes actual Transmilenio system capacity• Adaptability as mass transit network grows• A growing private vehicle ownership
