This publication is the second in a planned regular series that uses vehicle telematics data to provide measures of traffic congestion for freight vehicles on 53 selected routes across Australia’s five mainland state capital cities—Sydney, Melbourne, Brisbane, Adelaide and Perth. The selected routes comprise the major motorways, highways and arterial roads within each city that service both passenger and freight vehicles. The estimates presented in this report cover calendar year 2020, and includes a comparison with 2019 traffic congestion measures.
