WG4 was recently put in a dormant state in CEN TC278 to avoid the extra work involved in the Vienna agreement application. The technical work is progressing
at full speed, so this measure is purely to aid efficiency in the development process.
The following description therefore applies for ISO TC204/WG10, and will be moved there in the next issue of this report.
WG4 has been very active in the past, but the activity is mostly moved to TISA (Traveller Information Services Association) which is a non-profit organisation for TPEG, RDS-TMC (Alert C) and Graphic Data Dictionary. The main work is related to definition of data sets and transport protocols for sending traffic related information, mostly via public broadcast systems, but also via other media.
This is one of the most productive WGs with around 35 developing + published standards, and considered to be one of the most successful global sets of ITS standards, on par with CEN DSRC/EFC.
TPEG is a standard that will allow much larger data volumes to be sent to the on boards travel units. It is based on DAB radio communication and it will arguably take over for RDS-TMC in the future. TPEG is included as a communication and location standard for Datex II. A DATEX II-to-TPEG demonstrator was organized during the ITS European Congress in Lyon for which the technical explanation is available here.
It is recommended to follow this work and uptake of this standard closely in the coming years and evaluate if a transition to TPEG should be carried out in Europe, or if TPEG should be seen upon as a complement to RDS-TMC.
