Common MRWA HDM Scheme Features

To participate in an MRWA HDM 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 MRWA HDM scheme by downloading a copy of the Hill Descent Monitoring Schemes document.

To offer services for an MRWA 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.

TCA will analyse data received through the TMA application, and reports will be made available via the Telematics Analytics Platform (TAP).
