3: Spatial Nature

Process

The spatial analysis of this study revolves heavily around the space time cube feature of the Crime Analysis toolbar. We conducted a hotspot analysis on the georeferenced parking data to discern the extent of parking violations around the city of Vancouver. This analysis takes both spatial and temporal variables into account when creating the emerging hotspots. This analysis was done for 2019 and 2020 data and below we address particular differences with regard to the results between them.

For this visualization we also had the zoning layer visible beneath them which allowed us to systematically discern the prominent zones where each of the variables were present. We had four zones visible in particular, namely commercial, multiple dwelling, single family dwelling, and two family dwelling.

Limitations

In looking at the aspects of spatial correlations, we were not able to tangibly discern the proportion of parking tickets normalized to the zones. This idea was further fleshed out in the Potential Avenues Unexplored section of the first blog post.

For all the changes that came with 2020, the general patterns of hot and cold spots for parking violations within the city of Vancouver remained relatively similar. Downtown and False creek hold the greater majority of the hotspots throughout the city, and rightfully so as the city's major commercial and business centers.

Places that were diminishing cold spots in 2019 became intensifying cold spots in 2020. The areas of False Creek and Yaletown also saw a decrease in the prevalence of permanent hot spots, as the majority of their blocks became either oscillating or sporadic. Pseudo hotspots that were seen outside of these areas practically disappeared in 2020.

The cold spots on the other hand had far more interesting changes. The prevalence of cold spots became more intense from 2019 to 2020, as there were far less tickets being prescribed on any given day. The majority of the places considered diminishing cold spots in 2019 became either intensifying or persistent cold spots in 2020. Where in 2019 it was typical to see locations of oscillating cold spots and sporadic cold spots together in 2020 these places largely became sporadic cold spots with a major decrease of the amount of oscillating cold spots all together.
