Understanding transit-oriented development through bike-sharing big data

As one of over 20 million people who work and live in Beijing, China, I used to find commuting to work in rush-hour traffic rather painful. However, things have changed dramatically since last year. Now I can bypass the traffic by riding a shared bike to the closest metro station and make better use of public transit. Similar change is happening to my family and friends.

The unprecedented booming of dockless shared bikes in China presents a promising solution to the “last-mile problem” that has perplexed city planners for years: providing easier access to the mass transit system while ensuring good ridership. Thanks to the GPS tracking device installed on thousands of dockless shared bikes, city planners in China are now equipped with new and better information to analyze the demand for—and the performance of—public transit systems. For the first time, city managers can clearly map out the attractiveness and accessibility of metro stations by analyzing individual-level biking trips.

This innovation is good news to efforts to build more livable, sustainable cities through transit-oriented development (TOD). For example, to support the recently launched GEF Sustainable Cities Integrated Approach Pilot Project, we have been working with Mobike, a major bike-sharing company, to conduct an analysis utilizing the data of biking trips around metro stations in our project cities. Below are a few interesting observations:
  • Revisiting the scope of TOD. A commonly accepted textbook definition of the core area of TOD is an 800-meter radius around the metro station or other types of public transit hubs. This definition is based on the distance that can be reached by a 10-minute walk. However, the actual catchment of a metro station can reach a 2-3 km radius when biking prevails, as in Demark and Netherland. Our analysis illustrates that a big chunk of biking trips around metro stations even go beyond the 3km radius (see bright blue traces in Figure 1 below). This indicates that the spatial scope of planning and design around the metro stations should be contextualized. Accordingly, the price premium associated with adjacency to public transit service is more likely to be shared by a broader range of nearby real estate properties than expected.

Blog post of the month: Cycling is everyone’s business

“I’ve seen some of the highest performance bicycles in the world, but I believe the most powerful bicycle is the one in the hands of a girl fighting for her education, or a mother striving to feed her family.” 
- F.K. Day, Founder of World Bicycle Relief

  
The rainbow jersey, Giro d’Italia, Tour de France, or Vuelta a Espana—that’s what usually comes to mind when we think of cycling. However, elite cycling is only one small spoke of a much larger wheel.
 
By some estimates, there are already more than two billion bikes in use around the world. By 2050, that number could be as high as five billion. Over 50 percent of the human population knows how to ride a bike. In China, 37.2 percent of the population use bicycles. In Belgium and Switzerland, 48 percent of the population rides. In Japan, it is 57 percent, and in Finland it’s 60 percent. The Netherlands holds the record as the nation with the most bicycles per capita. Cyclists also abound in Norway, Sweden, Germany, and Denmark. The Danish capital, Copenhagen, is considered the most bicycle-friendly city in the world. It’s known as the “City of Cyclists,” where 52 percent of the population uses a bike for the daily commute. Bicyclist commuters are generally healthier than those who drive motor vehicles to work. They also remain unaffected by OPEC decisions about crude oil production or the price per barrel.
 
Due to the size of China’s population, and the need for bicycle transportation, statistics on the country’s bikeshare program are staggering. In a database maintained by Russell Neddin and Paul DeMaio, more than 400,000 bikeshare bikes are used in dozens of cities on the Chinese mainland, and the vast majority of those bikes have been in operation since 2012.  There are an estimated 822,000 bikeshare bikes in operation around the world. China, therefore, has more bikeshare bikes than all other countries combined. The country with the next-highest number of bikes is France, which has just 45,000.

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.
