The terms defined in MRTS201 General Equipment Requirements apply to this Technical Specification. Additional terminology relevant under this Technical Specification are defined in Table 2 below.
Table 2 – Definitions of terms
| Term | Definition |
|---|---|
| Approach | That section of road, consisting of one or more lanes, used by vehicles approaching an intersection or mid-block site. |
| Display | A signal aspect that is illuminated. |
| Fixed Time operation | A signal operation mode that allows for only a fixed sequence and fixed duration of displays. |
| Flashing yellow operation | A signal operation mode where the yellow aspects continually flash. |
| Manual operation | A signal operation method that allows each phase to be individually controlled by manually entering a demand for the next phase. |
| Master controller | The internal control processing unit hardware within the Master PTS unit which undertakes all communication and internal processing tasks required for operation. This controller controls the Slave controller operations. |
| NATA | National Association of Testing Authorities, Australia. |
| Operation Modes | PTSS operation modes include manual, fixed time, vehicle actuated and flashing yellow. |
| Portable Traffic Signal Unit (PTSU) | An individual portable traffic signal that consists of the traffic signal lantern, battery, communications equipment, mounting assembly and base. |
| Portable Traffic Signals System (PTSS) | Traffic light signals and associated equipment that provides signalling for temporary control of traffic at work sites. |
| RPEQ | Registered Professional Engineer of Queensland. |
| Hand-held Remote | A hand-held remote / device which can control and set the PTSS |
| Controller (HRC) | lanterns at a safe distance. This device may be wired or wireless. |
| Slave controller | The internal control processing unit hardware within the slave PTSU which undertakes all communication and internal processing tasks required for operation. This unit is subservient to the Master controller to which it is linked. |
| Traffic Controller | A person authorised to control traffic movements through site works by means of flags, stop / slow bats or other equipment. |
| Vehicle actuated operation | An operation mode that allows a variable sequence and variable duration of signal displays depending on vehicle (and pedestrian) traffic demands. All vehicle movements (phases) are actuated in fully- actuated operation in contrast with semi-actuated operation where only minor vehicle movements (e.g. side traffic) are actuated. |
| Yellow Time | Duration of the yellow signal for a phase or movement. This is static and pre-specified. |
