How do you feel about losing 5.7 days per year due to congestion?


Sydney, Melbourne and Brisbane are amongst the 25 most congested cities in the world, according to Inrix 2018 Global Traffic Scorecard. On average, Australian drivers commuting on those cities lost 137.6 hours (or 5.7 days) in congestion last year[1].

If you drive to work, perhaps this can make you think of alternative ways to commute each day. If driving is, in fact, your only option, it is a good time to ask for more transit/walking/cycling infrastructure to enable you to get to and from work easily.

The congestion Impact Rank developed by Inrix considers data from 200 cities around the world. The rank is determined by taking into account the hours lost in congestion and the city’s population. The top 5 most congested cities in the world in 2018 were:

(per capita)

1 (1) Moscow, Russia 210
2 (3) Istanbul, Turkey 157
3 (2) Bogota, Colombia 272
4 (4) Mexico City, Mexico 218
5 (5) Sao Paulo, Brazil 199

Australian cities are ranked as following:

2018 Impact Rank


City Hours lost in congestion

(per capita)

13 (12) Sydney 138
17 (15) Melbourne 118
24 (26) Brisbane 157

Sydney and Melbourne improved their ranking position in 2018 in comparison to the previous year but Brisbane jumped two positions from 26th to 24th place.

Whether Australian cities positions in the rank were impacted by other cities’ performance or an actual change in traffic congestion is not clear.  However, we do know that there are opportunities to improve our public transport services and cycling and walking networks which would certainly have a positive impact on reducing congestion.
