Urban Transport in the OIC Megacities

spaces. This poses a huge burden on public administrations to finance and build urban infrastructure

including roads, transit systems, and utilities such as water, sewerage and electricity. It is estimated

that under a Business As Usual (BAU) scenario, India’s urban growth alone will require almost 600

billion USD of investment by 2030, including 2.5 billion square metres of roads and 7,400 kmof metros

and subways. This is 20 times the capacity added in the past decade (Rode et al, 2014).

Alternatively, more cost effective forms of urban development which actively prioritise compact

urban growth, affordable mass transit and high levels of non-motorized transport use could bring

significant benefits to the current and future megacities of the developing world. Existing evidence

suggests that key urban infrastructure, particularly linear and networked infrastructures such as

streets, railways and other utilities, comes at a considerably lower cost per unit when the levels of

urban density are higher. For example, the World Bank suggests that more compact city development

in China could save up to 1.4 billion USD in infrastructure spending, equivalent to 15%of the country’s

GDP in 2013 (Rode et al 2014).

Within urban transport infrastructure provision, considerable capital cost savings can be generated

as a result of a shift away from private car infrastructure towards public transport, walking and

cycling. Furthermore, innovative urban transport systems such as Bus Rapid Transit (BRT) offer

significant cost savings compared to traditional metro and regional rail at similar capacity levels. For

example, Bogota’s TransMilenio BRT infrastructure had a capital cost of 5.8 million USD per km (or

0.34 USD per passenger), compared with estimates for metro rail of 101 million USD per km (or 2.36

USD per passenger) over three years. In addition, maintenance costs, which are frequently

underrepresented within major infrastructure cost appraisals, are substantially lower on a per capita

basis for affordable mass transit and non-motorized transport (Rode et al, 2014).

The operational costs of urban transport are also directly informed by urban formcharacteristics, with

sprawling urban development leading to higher costs and greater capital requirements relative to

higher density development. Low density urban development increases costs for both private and

public motorized transport, but it also undermines the viability of public transport provision for which

cost efficient operation is only possible above certain threshold density levels. Similarly, non-

motorized transport essentially relies on threshold densities. As a result, higher density cities have

greater opportunities for cost efficient transport provision (Rode et al, 2014).

Introduction

The physical separation of activities in an urban environment inevitably leads to longer distances

travelled

(Figure 1)

. Coordinated transport and land use planning allows authorities to build

sustainable mobility into the patterns of urban form and layouts, which may in turn lead to a switch

to greenmodes of transport. Policies that can contribute to the reduction of distances travelled include

increasing densities and concentration through mixed use development, housing location, design of

buildings, space and route layouts, public transport oriented development and transport development

areas, car free development and establishing size thresholds for the availability of services and

facilities. It is estimated that the timescale over which sustainable mobility might be realised is similar

to the turnover of the building stock (about 2% per annum), but decisions on the location of new

housing can have dramatic effects over the lifetime of housing (Banister, 2008).
