Common TMA HDM Scheme (WA) Features

To participate in a TMA HDM (WA) scheme, transport operators must conform with the requirements specified within the access approval (e.g. a Notice or permit). Enrolment in TMA is one of these requirements.

Find out more details on an TMA HDM (WA) scheme by downloading a copy of the TMA Hill Descent Monitoring Schemes document.

To offer services for an TMA HDM (WA) scheme, an application service provider (ASP) must be certified by TCA to offer TMA services. TCA must also approve telematics devices used in the scheme.

Reporting will be made available MRWA via the Telematics Analytics Platform (TAP).

TCA will forward specialised reports to MRWA personnel with access to data for compliance purposes to fulfill MRWA’s regulatory function. Specialised reports, specific to a hill, will contain data of individual and identifiable vehicles in relation to the specific measures listed in the scheme.
