Travel speed data from probes: comparison with EastLink e-tag data
Probes are devices which are either carried by travellers or vehicles, and which are able to relay their location and any available additional data in real-time at very frequent refresh rates. These devices include smartphones and in-vehicle telematics. Since 2012, the growth in smartphones has sparked a phenomenal growth in the volume of probe data points. Probe data points grew at more than 100% p.a. from 2009 to 2013. Probe data is an emerging source of information on transport demand patterns and performance of the transport network. To be accepted as fit-for-purpose for traffic management, probe data needs to be compared against reference data sets. This paper presents the results of the comparison of probe data and e-tag data on EastLink during lane closure, as a result of an incident. The analysis showed that probe data was able to estimate travel speeds similar to estimates from e-tag data.
