Public perceptions and support for policies enhancing safety and justice in connected and automated vehicles and vulnerable road users interactions

Abstract

Despite the anticipated benefits, the rollout of Connected and Automated Vehicles (CAVs) is likely to encounter numerous challenges, including public readiness to adopt and coexist with these vehicles. This study utilised a cross-sectional survey of 384 Australian residents aged 18 to 82 (M = 42.93, SD = 15.48) to assess public perceptions and support for policies designed to enhance safety and justice in interactions between CAVs and vulnerable road users (VRUs) such as pedestrians, cyclists and people with disabilities. Participants evaluated 15 policies (identified through a structured, expert-informed process as a preliminary stage) across five evaluation dimensions: acceptability for improving safety within the transport system, acceptability for improving justice within the transport system, perceived improvement of safety for all VRUs, perceived improvement of justice for all VRUs, and willingness to support each policy. Data were analysed using descriptive statistics, cluster analysis, and hierarchical regression models. Policies focusing on systemic improvements, such as VRU-focused infrastructure and technology enhancements, received strong public support. Public preferences align with policies promoting fairness and inclusivity, while punitive measures and VRU-burdening policies were resisted. Cluster analysis identified three groups: VRU-burdening policies (low support), VRU-centric safety policies (moderate support), and VRU-focused infrastructure and technology policies (high support). Regression analyses revealed that factors such as age, transport accessibility, and disability influenced policy support. A content analysis revealed a strong preference for prioritising public transport investment, implementing inclusive urban designs, and establishing robust ethical frameworks. The findings highlight the need for policies that prioritise VRU safety and justice in CAV deployment. Support for inclusive, non-punitive measures points to the importance of fairness and system-wide reforms. To transition toward a safer, more equitable transport system, the study suggests the potential for more radical, community-driven policies and increased transparency in CAV development.
