The TomTom Traffic Index has released its latest global report on traffic congestion, placing Bandung at the top of the list as the most congested city in Indonesia.
The report, published earlier this year, revealed that five Indonesian cities made the national top five ranking based on average travel time per 10 kilometres. Surprisingly, Makassar, a city often plagued by traffic delays, did not appear in the top five.
According to the index, it takes an average of 32 minutes and 37 seconds to travel 10 km in Bandung. Following closely are Medan at 32 minutes and 3 seconds, Palembang at 27 minutes and 55 seconds, Surabaya at 26 minutes and 59 seconds, and Jakarta at 25 minutes and 31 seconds.
The TomTom Traffic Index compiles congestion data based on Floating Car Data (FCD) technology, which analyses GPS data and real-time vehicle speeds. This allows for detailed monitoring of travel patterns, traffic density, and deviations from optimal journey times. The index evaluates three primary aspects:
- Static factors, such as road structure, speed limits, and route classification
- Dynamic factors, including weather conditions, construction projects, and vehicle volumes
- Optimal journey time, or the expected duration of a trip in ideal conditions
From this data, the system calculates how much longer drivers are spending on the road due to congestion, forming the basis of the ranking.
Jakarta No Longer Worst for Traffic, Says Governor Pramono
Jakarta Governor Pramono Anung has responded to the report, noting that Jakarta is no longer ranked as the most congested city in Indonesia.
Speaking at the launch of the Transjabodetabek Bekasi–Dukuh Atas transport link on Thursday, 3 July 2027, Pramono cited the TomTom Traffic Index as evidence of progress in the capital’s transport infrastructure.
“From a survey conducted by TomTom, you can see in the media as well, that Jakarta has been ranked number one in Indonesia, now it is ranked number five,” Pramono said.
The Governor acknowledged that while traffic in Jakarta remains a concern, its decline in the congestion rankings indicates ongoing improvements.
“Now number 1 Bandung, number 2 Medan, number 3 Palembang, number 4 Surabaya, number 5 Jakarta, which is encouraging again, so far Jakarta has always been in the top 10 in the world, now the number is far beyond that. So, it means that there is a serious improvement in transport in Jakarta,” he added.
Although Makassar did not appear in the top five, the city still struggles with daily traffic bottlenecks, particularly during rush hours. Local authorities are encouraged to reflect on these findings and implement measures to avoid joining the ranks of Indonesia’s most congested cities.
Globally, Barranquilla, Colombia, is ranked as the most congested city, with an average of 36 minutes and 6 seconds to travel 10 km. In Asia, Kolkata, India, led the regional list with 34 minutes and 33 seconds.
Meanwhile, Davao City, Philippines, recorded the highest congestion levels in Southeast Asia at 32 minutes and 59 seconds per 10 km.
