Enduring question 2.1

How well are Australia's infrastructure networks performing?

Gap addressed

• Consistent national approach for measuring road speed performance and reliability.
• The ability to conduct before and after assessments for road infrastructure projects.

Background

Houston Kemp has built a prototype road-speed performance dashboard for the Australian road network, using HERE traffic probe data (see example output below). The dashboard provides information on average road speed performance and network reliability at different times of the day. Performance and reliability measures are available for a number of spatial scales: citywide, major/arterial roads, postcode, point-to-point custom route selection, and for individual roads. Users can also view road

performance across several time dimensions, including hourly, AM and PM peak periods, by day of the week, monthly and annually. The prototype version was developed in 2017, using traffic data observed on Brisbane area roads over the period January 2013 to December 2016. The dashboard is currently only available to Infrastructure Department staff under commercial licence.

Objective

Expanding road speed performance dashboard to all capital cities and produce public facing metrics.

Project update

BITRE has commissioned Houston Kemp to expand the prototype dashboard to include near-real time data for all of Australia, including capital cities and other regional urban areas¹. Among other uses, the dashboard will enable before and after comparisons

to assess changes in road speed performance and reliability following infrastructure projects (e.g. new road construction, road widening projects).

Publicly-accessible road performance measures are also being developed for each capital city, which will be displayed on BITRE's infrastructure performance dashboard.

¹ The metrics in the expanded dashboard complement existing Austroads National Network Performance Indicators.
