The EWD involves the broad interaction between different participants in the EWD operating model, as indicated below:

EWD Operating Model

EWD Regulatory Framework Owner (NHVR) – responsible for:

  • Operational policy settings, and the ongoing roll-out strategy for the transport industry
  • Operational policy consistency
  • Operational activities relating to Transport Operators and Drivers
  • Compliance and enforcement operational policy, and ongoing monitoring.

EWD Service Provider (EWD-SP) – Private sector entities that provide telematics services (i.e. hardware, software and associated processes) and have their hardware and systems certified for provision of EWD services by TCA

EWD System Manager (TCA) – Responsible for the type-approval, certification and auditing of EWD Service Providers (EWD-SPs), and administering the technical and operational environment with which EWD-SPs interface. TCA will also develop, maintain, provide oversight and manage the Remote Connection Access Framework (RCAF) inclusive of the EWD Registry and Compliance Assessment Software (CAS). This will enable the compliance and enforcement task to be undertaken.

Drivers* – Drivers of heavy vehicles using the EWD to meet their fatigue management obligations.

Transport Operators* – Transport Operators of one or more heavy vehicles who have adopted the use of EWD.

Record Keepers* – Entities responsible for the record keeping task (it is assumed that the technical and operational function of the Record Keeper may be undertaken by EWD-SPs).

Road Transport Authorities – Participating Jurisdictional Authorities (under delegation to the NHVR) for the performance of roadside and/or back office assessment of Driver records (ie compliance and enforcement tasks).

Police* – Participating Police for the performance of roadside and/or back office assessment of Driver records (ie compliance and enforcement tasks).

Authorised Officers* - A person who holds office under the law as an authorised officer and is authorised to review Driver Data Records (effectively either State Road Transport Authorities or Police).
