Ipswich Connected Vehicle Pilot (ICVP)

Cooperative Intelligent Transport Systems (C-ITS) enable vehicles to ‘talk’ to other connected vehicles, roadside infrastructure and traffic management centre systems to share relevant safety-related messages for drivers. The driver remains in control of the vehicle, and there is no element of vehicle automation. The Department of Transport and Main Roads (TMR) led the largest Australian on-road pilot of C-ITS, of which CARRS-Q was a partner. This ran for 12 months from September 2020 in Ipswich, known as the Ipswich Connected Vehicle Pilot (ICVP). Around 350 public participants’ vehicles were retrofitted with this equipment, and received safety information and warnings from six use cases during their drives. The ICVP was delivered by TMR, supported by Motor Accident Insurance Commission, CARRS-Q, iMOVE Australia, Telstra, Ipswich City Council and Department of Infrastructure, Transport, Regional Development and Communications.

One of the objectives of the ICVP was to validate the safety impacts and user perceptions of C-ITS and pilot use cases (types of safety warnings). CARRS-Q contributed to this research through establishing and conducting a standardised research methodology for user perceptions (including questionnaires, interviews and focus groups), and contributing to the analysis of objective safety evaluation data. CARRS-Q also managed the participants throughout the pilot. The data and research findings will be used by transport agencies – local, state and federal – to support the investment of infrastructure, both digital and physical, that supports emerging C-ITS. In the future, these data and results could also be used by others to perform, compare or supplement the pilot findings (subject to relevant approvals).

CARRS-Q Research & Outcomes

To understand the safety impacts and user perceptions of C-ITS, CARRS-Q:

  • Researched the usability and ergonomic design of the human machine interface (HMI) for drivers to receive safety-related messages.
  • Conducted a series of questionnaires administered at four different points during the pilot to understand the participants’ experiences of the C-ITS over time, and particularly after experimental changes, for example, a change from seeing warnings, to no longer seeing warnings (that is, Treatment condition to baseline condition).
  • Interviewed over 50 participants at four different points during the pilot to further explore trends that arose in the questionnaires.
  • Conducted around 10 focus groups with approximately 50 participants at the end of the pilot to identify whether there were changes after the equipment was removed from their vehicles, and the participants had time to reflect.
  • Supplemented the ICVP with simulator studies with a different sample of drivers to those in the ICVP, to test use cases that were not available in the ICVP.
