Unsustainable GrowthProjected new urban built up area in developing countries alone is 400,000 km² (2000 – 2030)This equals the total urban built up area of the ‘entire world’ as of the year 2001 – we are building a ‘whole new world!’4 Earths (Ecological Footprint) required if developing country cities urbanize following the models of developed country cities

Stakeholder Collaboration is critical
1. Formal collaboration on three tiers
2. A shared planning framework
3. Integrated Design Process

Identify barriers to and opportunities for effective integration of the transit and land use in cities in developing countries.
Recommend a set of policies and implementation measures for overcoming these barriers and exploiting these opportunities.

Ahmedabad Janmarg – India’s First BRT
Development plan surfaced in 2005System built in 2 years (October 2007-Dec 2009)Janmarg BRT, 217 km planned in total of 4 phases
42
• Phase 1 complete• improved city’s mobility
Ridership: 135,000/daySpeed: 25km/ hour95% on-time departure
• Customer satisfaction is very high
Development Pattern (2006-2011)New development is apparent in city’s peripheryMore development concentration along the road
current and future BRT corridors
43
Brownfield development: redevelopment of closed textile mill parcels
Bogota: Beyond TransMilenio
44
Development plan surfacedMarch 1998
Construct 388km in 5 phases (1998-2016) Phase I and II are done
Phase I built in 36 monthsQuickly built
System’s service quality is recently deteriorating
Overcrowdedlowering average speedlong waiting
Development pattern (2004-2010)Changes in built environment (2004 - 2010)
Building density increased across the city, but not necessarily along the BRT corridors.More densification in spaces around end stations closer to city’s periphery, Overall, did not cause strategic densification and mixed-land use
45
• Bogota’s building density by FAR continues to be low, excluding some areas.
Key Barriers for Integration
AhmedabadRestrictive National Regulations(LC Act, Rent Control Act, Stamp Duties)Lack of Articulated Density –Uniformly Low FAR Small parcels and old low story buildingsMissing Transport Design No-Feeder System Non integrated Bike TrailMissing Micro and Street Designs No TOD Guidelines –Absence of pedestrian friendly design
BogotaInconsistency between City Level Master Plan POD and District Plan Lack of Regional CoordinationSector SiloLack of Articulated Density –Uniformly Low FAR Small parcels and old low story buildings)Missing Micro and Street Designs ( pedestrian bridge, empty wall, station rotary ) and No TOD Guidelines.
Articulated Density Matters;Not Average Density

Uniform Average Population Density can havetotally different height and spatial form. Whatmatters most for transit and land-useintegration is not average population density,but articulated density.

• DesignWorld‐class transit(trunk & distribution)
Station as hub)• Non‐motorized access(bikepaths, ped‐ways)
• Bikesharing/Carsharing
• Minimal Parking (reduced land consumption, buildingmassing &impervious surfaces)
• Energy self‐sufficient (renewably powered –solar, wind turbines)
• Zero‐waste (recycle;re‐use; methane digesters; rainwater collection for irrigation& gray‐water use)
• Community gardens(compost, canopies, food security)
• Buildings: Green Roofs, Orientation (optimal temperatures), Materials (reycled; low impact)
