Measuring road congestion – some new ideas

Congestion has been considered in ways new to Perth: relating SIDRA and SCATS measures of congestion; exploring a new level of service measure (Fsuffix) to show ‘how far we are into’ level of service F, then relating this to peak spreading; setting targets for maximum congestion using a ‘horses for courses’ approach rather than a single target level for all road types; developing new efficiency measures based on time lost through congestion to different road user groups; comparing community perceptions of congestion to technical measures; and adopting two future traffic growth scenarios with solutions related to both scenarios. The Fsuffix concept is theoretical, the practical manifestation of which is peak spreading. Fsuffix provides a new term for professionals to use when considering high levels of congestion. Peak spreading can be understood by the community. The ‘horses for courses’ approach matches community perceptions of congestion better than the ‘single level of service’ approach. It targets lower congestion on more important and more vulnerable routes, and higher congestion on less important routes. Most of these concepts are believed to be new to Australia, some new internationally.
