| Unlocking the Suburb | 71
through autonomous vehicles and active street management, suburban streets have the ability to shift within the diagram, moving from movement to place oriented when suitable. In this sense an entirely new type of street is developed, as the variable access street has the capacity to become truly place oriented, despite also being heavily movement focused when required. The question of when this shift could happen still remains, and to this end analysis has been done to understand the daily trip types and their frequency. The diagram below describes the peak times for which trips occur under each of the purposes. Plotted across 24 hours this reveals both an AM and PM peak, with the
frequency of trips dropping off significantly between these times for the suburban realm. Therefore, a suggestive period has been indicted between these two peaks as a potential window within which restricted vehicle access could be viable. Within this time the need for vehicle trips is reduced, and in a suitable neighbourhood, with appropriate weather, the shift of suburban streets to a pedestrian park space would yield the most benefits with the least inconvenience.
