This Technical Specification defines the design, supply, installation, testing and commissioning, performance, documentation, training, maintenance and handover requirements for Transportable Variable Message Sign (TVMS) and their associated control systems. A TVMS defined in this Technical Specification is used for traffic management and/or driver information applications. Transportable variable message signs intended to advertise products and services to road users are not covered within the scope of this Technical Specification.

This Technical Specification shall be read in conjunction with MRTS01 Introduction to Technical Specifications, MRTS50 Specific Quality System Requirements, MRTS201 General Equipment Requirements, MRTS202 Variable Message Signs, the Queensland Guide to Traffic Management Part 10 Transport Control – Types of Devices and other Technical Specifications as appropriate. The key differences between a VMS sign covered under MRTS202 Variable Message Signs and a TVMS covered under this Technical Specification are in relation to the:

1. a)TVMS operation is through the use of a handheld short range device (SRD) in addition to a remote sign control system (RSCS)
2. b)TVMS are battery powered and, where necessary, the batteries are recharged via solar panels, and
3. c)TVMS are mounted on a vehicle, trailer or a portable concrete block so that they can be relocated when required for traffic control staging.

TVMS complying with this Technical Specification shall only be used in accordance with the operational requirements of the QGTM Part 10. Vehicle-mounted TVMS shall, in addition, comply with the Queensland Manual of Uniform Traffic Control Devices (Queensland MUTCD) Part 3. This Technical Specification forms part of the Transport and Main Roads Specifications Manual.
