1 CHALLENGES OF URBAN GROWTH November 6, 2009 Jose A. Gomez-Ibanez OUTLINE: 1.CITIES AND ECONOMIC GROWTH 2.HCMC PROBLEMS  GROWTH, CONGESTION, FLOODING, HOUSING, DOWNTOWN AND FINANCE 3.HCMC PLANS  TRANSPORTATION, LAND USE Based on paper with David Dapice and Nguyen Xuan Thanh

2 CITIES AND ECONOMIC GROWTH BENEFITS OF AGGLOMERATION lEconomies of scale within firms lEconomies of agglomeration across firms and households lIn production: lWithin industries (cluster) lAcross industries (diversity) lIn consumption COSTS OF AGGLOMERATION lScarcity of central locations lCongestion, pollution, flooding CITY SIZE lTradeoff between marginal benefits and costs of agglomeration lMarket not necessarily optimal given that both benefits and costs involve externalities (spillovers)

3 OPTIMAL CITY SIZE (AFTER ALONSO) MSB MSC SOCIAL COST AND BENEFIT OF AGGLOM- ERATION CITY POPULATION

4 ROLE OF CITY GOVERNMENT MAXIMIZE AGGLOMERATION BENEFITS lGood business climate lIdentify, nurture clusters MINIMIZE AGGLOMERATION COSTS lEfficient infrastructure Transport, water, sewage, drainage lEfficient land controls Titles, density and use controls, state-owned lands EASIER FOR GOVERNMENT TO INFLUENCE COSTS THAN BENEFITS?

17 HO CHI MINH CITY TRAFFIC LANE PRIORITY CURRENT BUS PRIORITY (= bus and motorcycle) ( = bus only) MOTORCYCLE MEDIAN CURB SIDE PROTECTION ISSUES  Enforcement  Turns  Passenger access (if median)  Congestion on remaining lanes

18 INTERNATIONAL EXPERIENCE BUS RAPID TRANSIT (BRT) CHARACTERISTICS  Segregated busways and stations  High frequency services  High platform boarding  Pay before boarding  Special operators

19 CRITIBA BRT  1970, Brazil  15,000 phd

20 BOGOTA BRT  2002, Colombia  50,000 phd

21 2025 TRANSPORTATION PLAN 6 MRT LINES, 161 KM

22 2025 TRANSPORTATION PLAN 4 ELEVATED EXPRESSWAYS, 40 KM

23 INVESTING IN NEW CAPACITY 1.EXPENSIVE  MRT LINES: US$ 9.7 BILLION  ELEVATED EXPRESSWAYS: ~US$ 1.4 BILLION 2.LIMITED CAPACITY GAINS 3.IMPLEMENTATION PRIORITIES  MRT LINE 1 EAST  ELEVATED EXPRESSWAYS

24 INTERNATIONAL EXPERIENCE BRT PRO: High speed, high volume Cheaper, easier to build than Metro BRT: $2-$15 mil/km Metro: $50-350 mil/km LRT: $15-$40 mil/km CON: Not full separation from other traffic Spillover congestion
