How does accessibility re-frame our projects?

Tatiana Peralta Quiros's picture
The increasing availability of standardized transport data and computing power is allowing us to understand the spatial and network impacts of different transportation projects or policies. In January, we officially introduced the OpenTripPlannerAnalyst (OTPA) Accessibility Tool. This open-source web-based tool allows us to combine the spatial distribution of the city (for example, jobs or schools), the transportation network and an individual’s travel behavior to calculate the ease with which an individual can access opportunities.

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.

Nine suggestions for designing and implementing integrated fare systems

Integrated modal fares, which allow riders to access multiple forms of transit (such as trains or buses) using a single ticket or card, is an important poverty alleviation tool. This innovation is especially critical to low-income transit users that might be unable to afford the sum of multiple fares on their way to jobs, schools, health clinics or other facilities.

A wide range of local governments around the world have introduced integrated modal fares as a way to reduce the burden on low-income users. But the design of these systems requires a very thorough analysis of the urban transport modes being integrated. Bad design may foster inefficiency and lead to huge subsidies that the government, and ultimately the taxpayer, must pay for.

Here are some tips on how to prepare for the design and implementation of integrated fare schemes:

There was cause for celebration at the State of Rio de Janeiro’s Office of Women’s Affairs last week. The office had just launched a new program that provides support and legal assistance to survivors of gender-based violence, which was covered by a wide range of media and commemorated by a visit from senior World Bank leadership to Brazil.

Our team is currently visiting Rio to help with activities for this new program, called “Via Lilas.” Rio’s government has a lot to cheer about; the program is both innovative and significant.  Its primary component is a system of electronic kiosks, placed at stations along Supervia suburban rail lines, which contain helpful information about how women can seek support for gender-based violence.

The placement of these kiosks is strategic; the Supervia provides some of the poorest communities in the region access to jobs and services. 

​The rail service connects downtown Rio de Janeiro to the periphery in this sprawling metropolitan area of more than 4,500 square kilometers and 12 million people. Outlying parts of the metropolitan area, such as the community of Japeri, can be more than two hours by train to Rio’s Central station.

​The “Via Lilas” kiosks will be placed at high-profile locations along the Supervia system, providing easy information access to the approximately 700,000 passengers who use the rail network each day.

Public transport and urban design

As traffic congestion continues growing in urban areas, more and more cities have realized that investment priority should be given to public transport modes, such as metro trains, bus rapid transit systems (BRT) or buses, instead of personal vehicles. Simply put, public transport modes are more efficient than personal vehicles in terms of carrying and moving people around. However, international experiences also tell us that building more metro lines or putting more buses on the road alone may not be able to get more people to use public transport modes.

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.

​Smart measures in transport: Moving beyond women’s-only buses

Civil society has been dealing with the problem of sexual harassment in public spaces in innovative ways. Creative marketing campaigns are popping all over the world, including Take Back the Metro in Paris, Chega de Fiu Fiu in Brazil, and Hollaback in 84 cities around the world.
 
The problem seems to stem from strong, ingrained cultural beliefs. Unfortunately, the problem might be getting stronger as formal barriers to the participation of women decline, as suggests Marty Langelan, a World Bank consultant, professor of American University.

Specialists know that the complexity of the problem requires changes in social norms, and that this can only come from comprehensive approaches and time. Some governments may acknowledge the same; however, they still have to deal with the pressing urgency of the theme, and therefore adopt quick, pragmatic solutions.

Currently, countries like Mexico, Brazil, India, Malaysia, Indonesia, Thailand, Japan, and Nepal all have some form of women-only cars in public transportation.

While there are strong arguments that these women-only cars are effective temporary solutions, in the long-term they could reinforce the stereotypes of uncontrollable men and victimized women. They also remind us of the United States Supreme Court decision Plessy vs. Ferguson, which considered constitutional segregated black and white populations in public facilities under the idea of “separate but equal.”

​Using open tools to create the digital map of Cairo’s public transit

The first step in any transit planning process involves understanding the current supply and demand of transit services. In most of the countries where we work, understanding the supply of services is a messy, costly and lengthy process, since most cities have little knowledge of bus routes, services and operational schemes.
 
Having a digital map (GIS) and General Transit Feed Specifications (GTFS) details of a network allows a transit agency to do better service planning and monitoring, as well as provide information to its users. A traditional GIS software approach often requires a team of consultants and months of work.  Last month, however, we were presented with the challenge to use innovative tools do the same work in less than two weeks.
 
This was our first visit to Cairo, Egypt, and there we were tasked with the goal of mapping the city’s entire bus network (approximately 450 formal bus routes) in order to conduct an accessibility analysis with our new Accessibility Tool. At first hand this task seemed daunting, and a few days after arriving we were not certain that we could accomplish it in two weeks.
 
Before our trip, we had agreed on a somewhat flexible work plan, laying out an array of potential open-access, free tools that we could use depending on the scenarios we would encounter, mostly dependent on the availability of data.

How does this investment help accessibility for this metropolitan area’s poorest 40 percent?

Accessibility analysis is an essential element of understanding cities and public service delivery. Activity‐based accessibility measures relate to the distribution of activities (for example, jobs or schools) in a given space, and the ease of reaching these activities. This type of measure directly relates to the qualities of a multi-modal transport system (e.g. transport network, speeds and costs), but also includes the qualities of the land‐use system (e.g. distribution of land uses, and thus activities), and allows for a spatial temporal multi-modal analysis based on changing land uses.

Accessibility offers a powerful lens to assess how a mobility system is serving an urban area. For example, road congestion is a more severe constraint in a dispersed setting with few transit, walking and cycling options (such as the Atlanta metropolitan area), compared to traditional mixed-use downtowns (such as New York City), where residents can access jobs and other opportunities walking, cycling and using mass transit.

Accessibility indicators are not just conceptually powerful – they are also easy to operationalize: the number of jobs accessible within a 60-minute timeframe is a popular and powerful indicator to evaluate how well the mobility system is serving a particular spatial area, or group of people (such as the most vulnerable).

Is Public Transport Affordable?

When planning transport systems in developing countries, one of the main challenges is to evaluate the proportion of income spent by poorer households on transport as well as in understanding transport patterns in relation to residential location, travel distance and travel mode. High real estate prices in urban centers often force low-income households in developing countries to live farther out in the periphery, with consequences on the way urban agglomerations develop and with subsequent effects on the levels of motorization, congestion, local air pollution, physical activity and the expansion of urban poverty.

Replacing the car with a smartphone… Mobility in the shared economy

The sharing economy has been around for a long time. But recent technological advances like the development of real-time transactions through smartphones and credit cards have taken the potential of the shared economy to a whole new level, and opened the door for substantial changes in the way we think about urban mobility.

Recently, I was invited to join a panel on the sharing economy moderated by Prof. Susan Shaheen at UC Berkeley, focusing more specifically on shared mobility.

The panel acknowledged that shared mobility is already transforming the mobility landscape globally, but could go a lot further in increasing the sustainability of urban mobility systems. The panel identified a number of key research gaps that we need to pay close attention to if we want to create a policy environment that is conducive to mobility innovations. Three that I want to highlight are:
 
  • Supporting open data and open-source ecosystems is critical considering the tremendous potential of open-source software and data-sharing for improving transport planning, facilitating management and providing a better experience for transport users (for more detail, please see my previous blog on how the transport sector in Mexico is being transformed by open data)
  • Looking into shared-economy solutions for those at the bottom of the pyramid – solutions that don’t require credit cards and smartphones as prerequisites (see this blog on the bike-share system in Buenos Aires for a good example)
  • The world of driverless cars is coming – which, depending on how policy responds to it, could spell really good or really bad news for the environment: if such technology is used primarily in shared mobility scenarios, it could greatly reduce the environmental cost of motorized transport; on the other hand, the possibility of “empty trips” with zero-occupancy cars could exacerbate the worst elements of automobility (see Robin Chase’s blog in The Atlantic Cities for a great discussion on this). That is why it is critical to create a policy environment that appropriately prices the ‘bads’ of congestion, accidents and emissions while steering the world of driverless cars towards sharing and resource conservation.

On a recent trip to Mexico City, I had the pleasure of participating in three events that really brought home the transformative power of the open data and open source eco-system that is becoming an ever more important element of our work in transport.

First I joined the Secretary of Mobility for Mexico City to inaugurate an open data-based system for alerting public transport users in this city of 8 million of any disruptions to the city’s multimodal transport system consisting of an extensive metro system, a suburban rail line, 5 lines of the Metrobus Bus Rapid Transit system (BRT), an electric trolley system, as well as a substantial publicly operated bus system.  The alert system was built using open-source software on an open standardized data set of schedules supported by the Bank last year (read more about that initiative led by my colleague Catalina Ochoa).  Not only does this service deliver value for Mexico City commuters immediately, but it also allows any other city that has its data organized in a similar standard GTFS (General Transit Feed Specification) format (over a 1,000 cities do) to use the same code developed for Mexico City off GitHub, a web registry.  Moreover, the open standardized formats let developers in Mexico City or elsewhere build apps that use this information. The market for these applications is potentially global, spurring innovation for user-oriented applications in public transport: there are already many hundreds of GTFS based applications.
