CITI trial expanded

The Cooperative Intelligent Transport Initiative (CITI) is being expanded to include at least 50 light passenger vehicles.  This study will assess the safety benefits of vehicles communicating with other vehicles on the road.

Vehicles in the study will be fitted with a Cooperative Intelligent Transport Systems (C-ITS) device that can communicate with other vehicles or roadside infrastructure (such as traffic lights) also fitted with a C-ITS device.

Drivers will receive audio and visual alerts on a small screen installed on the dashboard if there is a situation that may be dangerous, such as the possibility of a crash with another vehicle. Drivers will also be alerted to a red light on approach to traffic lights fitted with C-ITS.

Drivers may receive three types of C-ITS alerts:

Intersection collisionHarsh breaking aheadRed light alert
Shows threat from left or rightActs as electronic brake lightLight is red or amber

Participants

We are inviting drivers who have a child attending school in the Wollongong area and drive to and/or from school at least three times a week, to participate in this study. Recruiting participants through schools increases the likelihood that connected vehicles will come into contact with each other. This allows a greater understanding of how connected vehicles interact and how their drivers respond to C-ITS alerts.

 

Timeframe

The CITI Light vehicle study will run for about 10 months. After installation, for the first 14 weeks of the trial, data will be recorded but no alerts will be issued, to establish a baseline behaviour pattern. This will be followed by 14 weeks where the C-ITS alerts are activated and data continues to be recorded. Additional time to install and un-install the C-ITS equipment, plus initial monitoring periods to ensure the systems are functioning correctly, will round out the trial period.

Analysing results

Participants will be asked to complete surveys and may be invited to attend a focus group, where they will have the opportunity to provide feedback on their experiences with the C-ITS device.  Data captured by the C-ITS device will be analysed to determine if there were any behavioural changes associated with receiving safety alerts during driving.

Ethics approval

The CITI Light Vehicle Study has received approval from the University of Wollongong Human Ethics Committee and the NSW Department of Education Human Ethics Committee.
