Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants include drivers aged 18-20 who have obtained their provisional (P1) drivers' licence. Once a participant has consented to participate, they will complete an online questionnaire around demographics, driving attitudes, and road pricing attitudes. All participants will then download a telematics technology-enabled smartphone app (developed specifically for this study) that will be able to track their driving behaviour during car trips.

Driving behaviour will be monitored for a 4-week baseline period during which they will not receive feedback. Participants will then be randomly assigned to either an intervention group or a control group. Over 20 weeks, intervention group will receive daily driving feedback and a personalised weekly driving score which will be linked to a financial incentive, all via the app. Participants will not be asked to interact with the app other than to review their weekly driving scores. The app will provide driving scores based on crash risk behaviour such as harsh braking, speeding, and drowsy driving. The app will not provide any other educational materials other than these scores.

Intervention group participants will begin with a starting amount of $120 (deposited into a 'safe driving account') and monthly deductions of $24 may occur if participants receive poor driving scores.

There will then be a 4-week post-intervention period, and participants will complete an abridged post-trial questionnaire. Participants' licensing details will also be captured in order to verify if any police-reported crashes occurred during the trial.

Both the intervention and control group participants will also be entered into a weekly draw for a $100 e-voucher. Draw winners will be chosen randomly, and participants will receive weekly SMS updates about the draw. As long as participants have location services enabled for the app, they will be eligible for the draw.

App analytics will be access in order to monitor adherence to the intervention. If the app analytics data indicate that participants are not adhering to the intervention (including disabling location services for the app), participants will be contacted via SMS or email to encourage adherence.

Behaviour
Comparator / control treatment
The control group participants will also complete the pre-trial questionnaire upon consenting to participate. They will then download the same telematics-enabled app, and driving behaviour will be monitored during the 4-week baseline period. However, once participants are randomly assigned to the intervention or control group, the control group will not receive feedback via the app, but will instead be eligible for the weekly draw for a $100 e-voucher.

Summary
Brief summary
By 2030, road crashes are predicted to be the fifth leading cause of death globally. Although Australia has made great strides in road injury prevention and safety, road fatality rates have plateaued over the last decade. Of concern is the fact that young drivers are overrepresented in road injury and fatality statistics in Australia - whilst young drivers comprise only 14% of all licence holders, they are involved in about one-fourth of all serious crashes (Australian Transport Council 2011). For young people aged 18-25, driving is a high-risk activity, with the risk of a crash greatest in the first six months of licensure (VicRoads 2005).

In-vehicle telematics presents a promising technological means of reducing road trauma. Telematics technology generates real-time motor vehicle data, such as acceleration and braking information, providing drivers with direct feedback on driving performance. Moreover, linking safety-specific feedback with financial incentives may achieve safer driving behaviours.

This study aims to assess whether personalised safety feedback linked to financial incentives will improve driving behaviour and reduce road crashes among novice drivers.

This study will be the largest trial of personalised transport safety feedback delivered using telematics technology in Australia. Recent aforementioned research highlights that personalised driving feedback and financial incentives shape safer driving behaviours (Mortimer et al. 2006; Stevenson et al. 2018), and this study will extend this important finding by assessing the likely impact that personalised safety feedback and incentives have on reducing the likelihood of road crashes. This study will be a crucial step in advancing scientific knowledge around road safety and enabling large-scale implementation of interventions to reduce road trauma.

A unique element of this trial is that it delivers across the entire state(s). Most technology trials have relied on participants and researchers in close proximity to ensure appropriate installation of the technology in-vehicle, and hence have been wholly delivered in urban environments. This trial, on the other hand, will overcome the underrepresentation of regional and rural young drivers in such studies. This is a significant strength as about two-thirds of serious injuries and fatal crashes occur in regional and rural areas.

In the past decade, hospitalisations from road crashes in Australia have not declined. As such, the market penetration of technologies like telematics highlights the opportunity to reduce the burden of road traffic injury. Furthermore, this research will provide decision-makers with data in order to guide policymaking. Our research will generate new knowledge that can be directly translated into transport safety policies associated with all newly licensed drivers.
