South-east Queensland roads are struggling in peak hour, with average speeds up to 43 kilometers slower than the speed limit during peak times.
Drivers could face snarls during traditional peak hours of 7am to 9 am and 4pm to 7pm, but the congestion lasts longer and occurs at unusual times.
HERE smart cities specialists Daniel Antonello says traffic congestion impacts people's happiness, where they choose to live, how productive we are as a society and the success of our economy.
Mr Antonello suggests our roads are already reaching capacity due to Brisbane’s rapid population increase.
