Problem Statement
For individuals or families looking to relocate in major urban cities like Toronto, Ontario, safety is a foremost concern. A significant aspect of safety is the accessibility and responsiveness of first responders in case of emergencies. This gap in information can lead to delays in emergency responses and coordination among different emergency service providers.
Project Design Specification
Notice that the map elements like scale bar, north arrow, and legend are not added within the web map. Since the web map can dynamically change as users zoom in and out, the scale bar might not accurately represent the map scale to Earth ratio, which can lead to misinterpretation. Moreover, the north arrow is not added to the web map because the main concern and focus of the map is with the relative location of neighborhoods and street layout in the city of Toronto, Ontario. Lastly, the image below represents the legend of the web map, which contains the symbol, line, and polygon representations used. As seen below, the legend is not integrated within the web map in order to enhance user control and reduce visual clutter, which leads to users being able to focus on the the city of Toronto without any distraction and constant reminder of what each symbol represents.
Furthermore, the symbols of police and ambulance/fire stations are equally important. By distinguishing these types of first responder locations, families are provided a nuanced understanding of the available emergency services around them. The use of the red and blue symbols to represent police and ambulance/fire stations is rooted and influenced by cartographic symbolism and public perception. The colour blue is commonly linked with police services, in which officers are often seen in police vehicle with blue lights and blue uniforms across various cultures. Similarly, the colour red is a global symbol to indicate medical and fire emergencies and is widely recognized on ambulances and fire trucks. Moreover, the selection of One-Way and Minor-Arterial roads for the road types are significant, such that these roads are often primary routes for emergency vehicles. Highlighting these roads on the map provide essential information about potential accessibility and response times.
Lastly, polygons with two different colours are used to represent and categorize each of the neighborhoods’ number of assaults and the rate (in %) these assaults are happening per 100,000 population in the year 2022. The colour green represents the neighborhood that is in the safer side with less than 100 assaults per neighborhood. The choice of colour is associated with how green signifies "go" or "safety". In contrast, the colour red represents the neighborhood that is in the less safer side with more than 100 assaults per neighborhood. Since red can be associated with "danger" or "caution", it is suitable to use this colour to represent neighborhoods with a higher number of assaults to imply a sense of alertness or caution when individuals or families are deciding. The inclusion of these information is significant for individuals and families who are looking to live and move to these neighborhoods - knowing which areas of the neighborhood that have a higher and lower assault rate can impact and influence their decisions to relocate. The map is interactive through web-based mapping, and although the data about the assaults are quantitative, the map is not implemented as a thematic map with a graduated symbology. Instead of a static colour gradient map, users can interact with the map through hovering and clicking different areas to access more detailed information about each neighborhood. Thus, enhancing the visual clarity and accessibility of the map, which makes it more user-friendly for the audience.
