Novo Transport Systems is proud of its ability to respond to customer demands as well as investment in research and design of innovative technology. These bolt on safety systems are testament to our commitment to providing leading edge solutions and have already been installed in numerous bus fleets since 2018.


The NTS-155 is a bolt on solution created by Novo Transport Systems. The system enables existing bus OEM door systems to be compliant with NSW Transport Roads And Maritime Services Technical Specification 155 (TS-155) bus door safety system requirements. The requirements came into effect in July 2018 - legislation can be found at this link.

  •      The system consists of a CPU/Voice Module, display screen and data logger, driver's door override switch, maintenance override switch, GPS module and driver's cockpit speaker.   
  •      The NTS-155 utilises the bus body OEM’s door signals and door entrapment sequence. This, in turn, controls the chassis OEM supplied interlocks to meet the specific functionality requirements of TS-155.
  •      The NTS-155 data logs all the various components within the system and allows for easy data retrieval.

We have introduced our 2nd generation NTS-155 in 2021, which now incorporates a more comprehensive certification process for installation and on-going maintenance.
