Drivers in the Colombian capital lose 191 hours a year to congestion, according to the 2019 Inrix Global Traffic Scorecard, which identifies and analyses trends in more than 900 cities.
The Colombian capital of Bogota tops the list of the cities most impacted by traffic congestion, causing drivers to lose 191 hours a year, according to the 2019 Inrix Global Traffic Scorecard. It was followed by Rio de Janeiro (190 hours), Mexico City (158 hours) and Istanbul (150 hours).
The transportation analytics company’s index identifies, analyses and ranks congestion and mobility trends in more than 900 cities, across 43 countries. To reflect an increasingly diverse mobility landscape, the latest scorecard includes both public transport and biking metrics for the first time.
Latin American and European cities again dominated the top 10, highlighting the rapid urbanisation occurring in cities that took shape long before the age of the automobile.
The ten most congested cities are:
Bogota, Colombia (inner-city last-mile speed 9mph)
Rio de Janeiro, Brazil (15 mph)
Mexico City, Mexico (12mph)
Istanbul, Turkey (11mph)
Rome, Italy (11mph)
São Paulo, Brazil (13mph)
Paris, France (10mph)
London, UK (10mph)
Boston, Massachusetts (11mph)
Chicago, Illinois (11mph).
According to Inrix’s data, travel speeds, congestion rates and time loss positively correlate with population and city density but motorists in high congestion cities do not typically travel as far since they are geographically closer to more destinations.
“It is the driving experience that differs most across cities, not the duration of trips,” states the Inrix report.
It adds: “Typically, dense cities experience low speeds and shorter commute distances in contrast to low-density cities which exhibit higher speeds, but longer distances travelled. In both contexts, commuters spend approximately a half-hour on average commuting to or from work.”
One notable exception to this trend is Singapore, with Inrix highlighting its “aggressive anti-congestion policies”, including high vehicle ownership fees and congestion tolls.
Typically, dense cities experience low speeds and shorter commute distances in contrast to low-density cities which exhibit higher speeds, but longer distances travelled.
The report also identifies the reprioritisation of street space from vehicles to alternative uses, including bus lanes, bike lanes and loading zones, as a trend that continues to gain momentum globally.
“Within the United States, the banning of private vehicles on Market Street in San Francisco, and the highly successful 14th Street Busway in New York City are prime examples,” says Inrix. “When interpreting the 2019 Global Traffic Scorecard’s results, understanding the context of road performance within a city’s broader mobility framework is critical.”
Inrix fuses anonymous data from diverse datasets, such as phones, cars, trucks and cities. The data used in the 2019 Global Traffic Scorecard is the congested or uncongested status of every segment of road for every minute of the day, as used by millions of drivers around the world that rely on INRIX-based traffic services.
The 2019 scorecard builds on the 2018 report by identifying multiple commute areas within cities, capturing each city’s own unique mobility profile. It analyses travel times between modes and the impact of incidents on congestion within a city. From this multifaceted approach, a holistic understanding is achievable in an increasingly complex landscape, says Inrix.
