According to research published in 2021, Mumbai is the world's fifth-most congested city

According to the 2018 TomTom Traffic Index, based on a study of 404 cities across 58 countries, Mumbai was India's and the world's most congested city in 2021. After Moscow a year ago, the metropolitan city was the world's second most congested city.

To help governments plan infrastructure improvements and establish additional public transportation schemes, TomTom provides real-time traffic management and historical traffic congestion data.

 

In 2021, Mumbai had a congestion level of 53%, followed by Bengaluru and New Delhi (both at 48%), and Pune (at 42%). The city's peak traffic has decreased from 75% to 69 percent. It was 91 percent in 2019. Peak traffic was down 22% in 2021 compared to the years before the COVID-19 epidemic.

 

The proportion of time spent in congested traffic is an indicator of the additional time a driver must spend getting from one location to another over and above the time required in normal and free-flow traffic circumstances. A 50 percent congestion level suggests that on average, travel times were 50 percent greater than during the baseline uncongested scenarios. This means that a 30-minute commute in free-flow conditions will take 50c/o longer, or 15 minutes longer, when congestion is at 50c/o.

 

TomTom determines the baseline for each city by analysing the free-flow travel times of all cars on the whole road network at all times of the year, 24 hours a day, 365 days a year. According to the index, Mumbai's worst traffic day occurred on August 21, 2021, when three religious festivals fell on the same day. Changes in working patterns consolidated in 2021, according to Sachin Tyagi, TomTom's strategic automotive business development manager. "Many businesses are adopting the home office as a standard.
