The World Economic Forum released its most recent Sustainable Cities Mobility Index, which ranks some of the globe’s largest metropolises based on both the viability of transport and its relative footprint.
The Index measures factors such as connectedness via public transport, including metros and buses, as well as pedestrian accessibility, ease of use by cyclists, among others. What unites each of the five cities featured here seems to be the overall strategy of incentivizing use of public transport, while disincentivizing the tendency to commute by automobile. In this way, public transportation systems trade on efficiency: by running frequently, integrating renewable energy sources, and maximizing often-limited physical space in the crowded cities, the public transport strategies of each of the cities listed have served to reduce car emissions significantly.
HONG KONG. Named number one on the sustainable mobility index, Hong Kong has constructed an impressive MTR metro system, which is responsible for 90% of residents’ daily journeys. Likewise, the cost of transport in Hong Kong has remained relatively low, permitting accessibility to all residents, further disincentivizing travel by car. In fact, due in large degree to the success of the public transportation system, less than 20% of residents of Hong Kong own a car.
ZURICH. At number two on the list, Zurich has demonstrated a great deal of success minimizing transportation by car, with just 37% of the population owning a car, as well as a little over a quarter of journeys measured occurring by car. The majority of public transportation in Zurich occurs by high-speed light rail, a system widely recognized to be one of the most energy- and space-efficient modes of public transport.
PARIS. In 2012, Paris pledged to reduce travel emissions by 60% within the most populated areas of its city, introducing more networks of pedestrian walkways and bike paths, incentivizing the use of bicycles and electric cars through two new city rental systems, as well as altering delivery systems such that it limits the number of diesel-fueled vehicles driving through the city each day. Parisian city officials have also been working to initiate regular “car-free” days, as well as other measures that promote alternative forms of transport.
SEOUL. Throughout the past decade, Seoul has pioneered a significant number of innovations that promote sustainable mobility. An inefficient highway system has been repurposed to become a large public park with an extensive network of pedestrian causeways. Moreover, Seoul has employed specified bus lanes, which have increased by nearly one million the number of citizens who use the public transport system each day, as opposed to driving. The significantly greater efficiency of public transportation, as well as the ease of access afforded to pedestrian traffic has cut down greatly on the number of citizens commuting by car, one of the most inefficient and least sustainable modes of travel.
PRAGUE. Prague has undertaken the “Tune Up Prague” initiative, just one of a series of sustainable transportation proposals enacted under the 2015 Sustainable Urban Mobility Plan. The “tune up” has focused on increasing foot and bicycle travel through the facilitation of pedestrian pathways. The proposal has also worked to bring accessible, sustainable transportation to all, seeking to bump up the amount of wheelchair-accessible metro stations by 23%, such that 95% of the city’s metro stations are wheelchair-accessible.
In integrating energy and space-efficient public transport with initiatives that promote pedestrian and cyclist travel, the five cities listed above have developed transportation networks that are both accessible and sustainable. Incentivizing public transport increases a city’s ability to experiment with “greener” travel, while simultaneously reducing automobile emissions. The ingenuity of each of the five metropolises provides a crucial example for other major cities, working towards a more sustainable, more connected future.
