3) Mass Rapid Transit (MRT) • MRT can contribute to (benefits) • Urban efficiency • The need of the poor in large urban areas • But MRT imposes a heavy fiscal burden • These benefits do not always accrue • Financing damage local economy & preclude other social investments • Passenger flows are overestimated
Central challenges • Identify the strategic objectives • Explore means (technology, finance, pricing) • Secure the benefits • Evade the risks • Optimal mix of technology and staging of MRT expansion
Its role within city development strategy • reduce congestion (particularly rail-based) • permit city center activity, i.e., avoid urban sprawl • Provide basic accessibility (poor cities) • Affordable • Assessment of MRT should be made in accordance with the strategy
Its role to urban structure • Allow central business district continue growing (structuring effect) • Focus on the city center, and save on public infrastructure costs in other areas • Avoiding the costs -> merits of MRT
Choice of technology • Busways • Light Rapid Transit (LRT) • Metros (heavy railway system) • (See table 8.1 for performance and costs)
3.1) Busways • The least-expensive form of MRT • Costs between $1- $8 millions per km • Sophisticated system costs $15 millions (Quito & Bogota) • Well-designed system has capacity up to • 20,000 pphpd (Curitiba) • 36,000 pphpd (Bogota) with reduced speed of 20 km per hour
Busways (cont.) • For successful system needs strong political commitment in • Planning • infrastructure management • Service management and procurement • Rare in developing countries • Regarded as a relatively primitive system • Capacity is seen as limited
3.2) Light Rapid Transit (LRT) • Ranges from • on-street tramway (Eastern Europe) • to elevated & segregated system (Malaysia & Singapore) • Costs between $10- $30 millions per km • Functions as • High-quality alternative to cars • Feeder to heavy rail system
