Abstract
Several fire safety benefits are realised when considering autonomous vehicles (AVs) using parking buildings. Hazards posed by the increasing number of alternatively powered vehicles on the road, such as electric vehicles (EVs), may be mitigated. Parking AVs in designated zones would allow for the installation of fire-suppression systems other than those that are water-based, permit alternative ventilation requirements and allow for the reconfiguration of the building structure. Connected AVs could communicate with other vehicles, the parking building and the emergency services, resulting in a more effective response to a developing fire incident. However, AVs may increase fire safety hazards when considering alternative parking arrangements that promote more extensive fire spread, increase the median fire load energy density by at least 13% and inhibit firefighting. This may impact on the operational capability of the emergency services and the expectations of the structural fire safety design of the building. In this paper, options are presented that would influence the design and use of parking buildings where AVs and EVs are present. Presently, it is unclear whether the introduction of AVs will increase or decrease the fire safety risk to life and property, and further research is suggested to better understand such matters.
