Land Use and Transport for Low Carbon Cities

Transcription

1 Land Use and Transport for Low Carbon Cities Sunny Kodukula, Project Coordinator, Wuppertal Institute for Climate, Energy and Environment UNCRD - Environmentally Sustainable Transport (EST) Forum October 2018, Ulaanbataar, Mongolia

2 Cities Cannot live without them, cannot live in them, Can we adapt them? Home to over 50% of the population Economic centres for countries Magnets for opportunities Larger the cities higher the labour opportunities Are also large polluters Consume land and energy Contribute to environmental problems at a larger scale

3 Slumless smokeless cities (1902) Garden city Green Metropolis Ebenezer Howard 2 cities built! - Welwyn Garden City and Letchworth Garden City, both in Hertfordshire England

4 The 1925 view of a 1950 city

5 Atomurbia (1946)

6 The Le Corbusier Model

7 Kinds of cities 1: Monocentric city 2: Dispersed city Or how cities evolved and how we want them - Black arrows are strong links - Brown arrows are weak links 3: Composite city 4: Urban Village Concept of Alain Bertaud, 2001

8 Way we live Paris: 7,877,000 people 1,176 km 2 Jakarta: 14,908,000 people 2,942 km 2 Moscow: 8,543,000 people Shanghai: 7,397,000 people 470 km km 2 Berlin: 4,212,000 people 1,176 km 2 Alain Bertaud, 2001 London: 6,626,000 people 1,062 km 2 New York: 10,752,000 people 2,674 km 2 Scale: 100,000 people

20 Tale of two cities Population: 5.25 million Urban area: 4,280 km 2 CO2 Emissions from urban transport: 7.5 T CO 2 /ha/yr (public + private transport) About 500,000 public transport trips / weekday Atlanta, GA, USA Population: 5.33 million Urban area: 162 km2 CO2 Emissions from urban transport: 0.7 T CO2 /ha/yr (public + private transport) About 2.6 million trips / day 953 million boardings/year Barcelona, Spain

21 Car oriented planning Low Density Segregated Land Use Excessive road infrastructure Preference to mobility over accessibility

22 Why do cities grow? What is land use/transport? What influences it? What does it influence? Source: Sustainable Urban Transport Plans (SUTP) and urban environment: Policies, effects, and simulations

23 The 3Ds of land-use Density Diversity / mixed land use Design Destinations (availability of jobs etc.) Distance to transit

24 Density

25 Houston, TX, USA Source: Density: How not to Inhuman scale Not integrated with transit Segregated zoning What is the problem with a downtown? Source:

26 Diversity Is this diversity?

27 Diversity Mixed Land-use reduces the necessity to make some trips Distance travelled is greatly reduced Complemented by a good public realm with space for walking and cycling Source: City of Buenos Aires, 2015

29 Who do we design the spaces for Source: City of Buenos Aires, 2015

30 Design of services Not just urban space Source: City of Buenos Aires, 2015

31 Transit Oriented Development A transit spine Core high density Decreasing densities Transit line Medium-density residential High-density commercial and residential Transit station High-density residential

32 In the TOD Core is Transit bound Walking at 200 m Cycling upto 800 m

33 Example from Curitiba

34 Intervention from Bogota Govt. to locate public facilities (schools, colleges, recreational centers, etc.) along PT corridors Bogota built several schools along TransMilenio corridor

35 Copenhagen Concept of 1947 Over 170 kms of s-tog train lines Over 400 km of bicycle lanes

36 Barcelona

37 Superblocks benefits

38 In conclusion Growing Economy Car ownership Traffic volumes Urban Sprawl Longer trips Time lost in traffic Higher infrastructure costs Climate Change Higher emissions Air pollution Road Safety Higher speeds Increased Fatalities Conflict among modes Energy Consumption Transport consumes about 30% of energy GHG Emissions

39 What carries how much? Suburban Rail (e.g. Mumbai) Equivalency road width: In order to carry 20,000 automobile commuters PHPD, a highway must be at least 18 lanes wide. (assumption 1.2 passengers per automobile) Mixed Traffic Regular Bus BRT single lane Cyclists Pedestrians Light Rail BRT double lane Heavy Rail/ Metro PPHPD Range 1.5k-2k 5k 9k 14k 19k 18k 20k?? 40k 60k 60k 90k Maximum PPHPD achieved 2k 8k 15k, Curitiba 14k 19k 20k 43k, Bogota 80k, HKK >100k, Mumbai Source: Manfred Breithaupt (2016) based on Botma & Papendrecht, TU Delft 1991 and own figures

41 What to prioritise Cities for People OR City for cars

42 How do we do it? Integrate land use and transport Don t focus on single corridor solutions Integrate, integrate, integrate Don t control land prices but guide urban development Know what kind of city you want!

43 Questions for you. Land Value Capture Any other alternatives to TOD? What is being done in your city?
