Improving active mobility safety at signalised intersections using drone footage

The intersection of George Street and Wellington Street, West Perth, is signalised with pedestrian/bicycle crossings. Analysis of crash data revealed that cyclists are particularly at risk at this intersection. To gain a deeper understanding of user behaviours at this intersection, drone video footage was processed to produce telemetric data (direction of travel and speed) for vehicles and vulnerable road users (VRUs). By subsequently synchronising the footage with signal phases, it was possible to analyse several metrics that are difficult or costly to accurately collect by other means, including VRU crossings on red or green aspects and waiting times. The analysis revealed a high proportion of VRUs crossing on a red aspect, which was tied to the signals not being sufficiently optimised for VRUs or vehicles. The results were presented to the relevant roads authority which is now actively considering actions to improve safety for all road users at this intersection.
