It is the end of another hot day in Rio de Janeiro. I’m tired and sweaty after spending the afternoon checking out the progress on some of the city’s train stations, which are being renovated for the upcoming Olympic Games. But I’m also happy, having witnessed the progress made in improving Rio’s suburban rail system, known as SuperVia, which the World Bank has been supporting for the last 20 years.
Using the OTPA Accessibility tool, we are unlocking the potential of these data sets and analysis techniques for modeling block-level accessibility. This tool allows anyone to model the interplay of transportation and land use in a city, and the ability to design transportation services that more accurately address citizens’ needs – for instance, tailored services connecting the poor or the bottom 40 percent to strategic places of interest.
In just a couple of months, we have begun to explore the different uses of the tool, and how it can be utilized in an operational context to inform our projects.
Comparing transportation scenarios
The most obvious use of the tool is to compare the accessibility impacts of different transportation networks. The tool allows users to upload different transportation scenarios, and compare how the access to jobs changes in the different parts of the city. In Lima, Peru, we were able to compare the employment accessibility changes that were produced by adding a new metro line. It also helped us understand the network and connectivity impacts of the projects, rather than relying on only travel times.
Understanding spatial form
However, the tool’s uses are not limited to comparing transport scenarios. Combining the tool with earth observation data to identify the location of slums and social housing, we are to explore the spatial form of a city and the accessibility opportunities that are provided to a city’s most vulnerable population. We did so in Buenos Aires, Argentina, were we combined LandScan data and outputs from the tool to understand the employment accessibility options available to the city’s poorest population groups.
There are several non-transport factors, or urban design factors, that play a critical role in a traveler’s decision on their best travel mode.
The first critical factor is density. As illustrated in a famous study done by Alain Bertaud, a former World Bank staff, density is the primary reason why 30 percent of daily trips are carried out by public transport in Barcelona, but only four percent in Atlanta. Barcelona is about 30 times denser than Atlanta, so it is therefore much easier to provide same level of public transport services in Barcelona than Atlanta.
One lesser-known factor is accessibility. Just having a high population density may not guarantee more people to use public transport.
With 75 percent of the infrastructure that will exist in 2050 yet to be built, actions taken right now will shape urbanization patterns and quality of life for decades. It is urgent that global leaders concentrate now on ensuring that cities are sustainable, inclusive and prosperous.
The year 2015 provides three big opportunities to build global momentum around the course for change. These are the potential for a binding international climate agreement coming out of COP21, a new development agenda set forth by the UN Sustainable Development Goals (SDGs), and a platform for prioritizing safe, equitable cities through the UN Decade of Action for Road Safety. The coming year raises the stakes, with the 2016 Habitat III conference expected to be one of the most influential gatherings in history focusing on making cities more livable and sustainable.

Last year marked an important tipping point: for the first time, half of the global population lives in cities. Cities currently add 1.4 million people each week and this population growth comes with new buildings, roads and transport systems.
In fact, 75 percent of the infrastructure that will be in place by 2050 does not exist today. With cities poised to invest now in infrastructure that will last for decades, huge opportunities lie ahead. But without major shifts now in how we manage established as well as rapidly growing cities, we risk losing out on the potential of urbanization to create more inclusive and prosperous societies.
2015 offers a big chance for the international community to help put cities on a more sustainable path. We at the World Bank and the World Resources Institute (WRI) believe that we must seize this opportunity, because cities and urban mobility are key to a sustainable future.
Business-as-usual urbanization patterns come at a hefty price. Cities already produce 70 percent of energy-related greenhouse gas emissions and traffic crashes claim 1.2 million lives per year, with developing cities carrying the greatest burden.
Traffic congestion cost Rio de Janeiro and São Paulo a combined $43 billion in 2013 alone, equivalent to 8 percent of each city’s GDP. In Beijing, the costs of congestion and air pollution are estimated at 7-15 percent of GDP. Urban sprawl costs the United States alone $400 billion per year.
This is not the future we want for our cities.
Every year, more than 1.2 million people die in traffic crashes worldwide, equivalent to nearly eight Boeing 747 plane crashes every day. As developing economies grow and private car ownership becomes more mainstream, the number of associated crashes and fatalities will continue to rise.
The challenge of traffic safety often flies under the radar in cities, where the social and economic challenges of accommodating growing populations take precedent. Without meaningful change, however, the World Health Organization (WHO) projects that traffic crashes could become the fifth leading cause of premature death worldwide by 2030. This takes a particular toll on cities, which are already home nearly half of global traffic fatalities. City leaders must prioritize traffic safety measures to ensure that their citizens have safe, healthy and economically prosperous cities to call home.
With Urban Growth Comes Traffic Safety Challenges
While there are a number of factors that contribute to traffic crashes, two of the primary challenges are rising motorization trends in cities worldwide and the issue of road equity: the most vulnerable road users, including pedestrians and cyclists, are most impacted by traffic crashes. On top of that, these users, typically lower-income, don’t always have the power or capacity to create the necessary changes.
The number of privately owned cars on the road hit the one billion mark for the first time in 2010. If we continue business-as-usual, that number will reach an estimated 2.5 billion cars by 2050. All of these new cars will lead to an increase in traffic congestion in cities worldwide, increasing the probability of traffic crashes and resulting fatalities.
In many developing cities, transport infrastructure – whether it be roads, metro systems or BRT - is not growing fast enough, and cannot keep up with the ever-increasing demand for urban mobility. Indeed, constructing urban transport infrastructure is both expensive and challenging. First, many cities do not yet have the capacity to mobilize the large amount of funds needed to finance infrastructure projects. Second, planning and implementing urban transport infrastructure projects is tough, especially in dense urban areas where land acquisition and resettlement issues can be extremely complex. As a result, delays in project implementation are the norm in many places.
Therefore, solving urgent urban transport problems in these cities requires us to think outside the box. Fortunately, the rapid development of ICT-enabled approaches provides a great opportunity to optimize and enhance the efficiency of existing and new urban transport systems, at a cost much lower than building new infrastructure from the ground up.
The term “sustainable transport” evokes a wide range of images and perceptions among transport professionals and lay people alike. For some, it means a range of technology solutions – from diesel particulate filters to ebikes, Copenhagen wheels, or buses running on compressed natural gas. For others, the term can refer to changes in behavior, like improving the way vehicles are maintained or driven, or efforts to carpool. For yet others, the term implies even more radical changes, like wholesale shifts in the way cities are designed, and/or smart city approaches that use ICT technologies to fundamentally change the way people interact with their surroundings. “Sustainable Transport” can mean any or all these things, including expanding access to transport services in rural areas.
But however the term is interpreted, it is not normally associated with Africa. Indeed, in many respects, common images of African transport are synonymous with unsustainability – high rates of traffic growth and congestion (even in cities with comparatively low motorization rates), high traffic injury and fatality rates from substandard road safety practices, highly polluting vehicles, minimal formal public transport services, poor enforcement of road worthiness and vehicle overloading– and the list could go on.
It is then very telling that the inaugural conference of the Africa Sustainable Transport Forum took place in Nairobi, Kenya in late October, with not only a great deal of interest but also high-level participation (with delegates from 42 African countries, including 25 Ministers). The conference was hosted by the Kenyan government, with support from the World Bank-led Africa Transport Policy Program (SSATP) and the United Nations Environment Program (UNEP). The Ministerial portion of the conference was opened by both President Kenyatta and Secretary General Ban Ki Moon.
Over three days, technical experts and ministers discussed what transport sustainability means for the continent, resulting in the first ever Sustainable Transport Action Framework for Africa. There were a number of other “firsts” associated with the conference: the first time African transport and environment ministers gathered together to discuss transport issues; the first time that “sustainability”, as a key objective of transport policy in Africa, was the focus of the agenda; and the first time that a Secretary General of the United Nations had ever opened an international conference focused on transport.

Lamentablemente, el desfinanciamiento de los sistemas de transporte urbano es un problema generalizado, difícil de remediar con presupuestos públicos sobrecargados y/o soluciones inmediatas que aunque efectivas en teoría son difíciles de implementar en la práctica: el aumento de tarifas, por ejemplo, es una medida políticamente difícil y además genera mayor presión sobre los pobres, quienes más usan el transporte público; cobrar una tarifa que realmente cubra los costes socioeconómicos del uso del vehículo particular (tales como cargos por congestión) como instrumento de financiación del transporte público es también una medida impopular y difícil de implementar.
Dada esta situación, los operadores de transporte están continuamente buscando nuevas formas de recaudar fuentes adicionales de ingresos y así disminuir el déficit de financiación, en muchos casos a través de asociaciones con el sector privado. A pesar de que muchos de los ejemplos se concentran en países desarrollados, algunos metros en América Latina y en otras regiones en vías de desarrollo están buscando aumentar sus ingresos no tarifarios:

Unfortunately, the underfunding of transit systems can become chronic as public budgets are under growing pressure and the most direct solutions for increasing revenues are hard to implement: increasing fares, for instance, has proved to be politically difficult and disproportionately affects the poor, who use public transport the most; and charging a price that fully covers the social cost of private vehicle usage (i.e., congestion charges) as a way to fund transit is also politically sensitive.
In that context, transit operators are increasingly looking at new ways to tap additional sources of commercial revenue and make up for funding shortfalls, often through agreements with the private sector. Although most examples are concentrated in developed countries, some metro systems in Latin America and the developing world are looking at ways to increase non-tariff revenues:
