The final site was selected as the police call box (PCB) and the following method was used to select the most suitable sites by overlaying them.
I chose the police call box (PCB) distributed throughout the city as my site, so my site scope is relatively special.
I marked all the PCBs recorded in the city by searching the literature. Different colors only represent different zones, and the circular dots are the areas in question. The PCB there may have been removed or sold to citizens when it was documented.
Edinburgh has a total of 142 police call boxes, of which 55 were sold to citizens in 2012 and 2014 respectively.
The target customer groups I chose are overseas students, which will explain why in the following pages.
Then I annotated all the student accommodations registered on the Google map and overlapped the two layers for site selection.
It can be found that the distribution of student apartments is roughly built around prince street and old town. And most of the student dormitories are built in different colleges near the university, so you can also know what major the mainstream students in the dormitory are through the nearby colleges.
The PCB that is no longer in the market place after checking the address is deleted, and the PCB that has no student apartment within 500m in diameter is deleted. I get the following result.
The radiation range with a diameter of 200m is spread out in each student dormitory, and the PCB with three or more intersecting ranges is selected as the expected site, marked in red. Take 2 or fewer PCBs within the intersection range as possible site selection marked orange. That gave us 15 expected locations. Nine red, six orange.
At the same time, the actual position of PCB was visited and adjusted, and the nine sites marked in red were finally determined. But one particular case remains unsolved.
That is, the PCB corresponding to mark No. 2 in red in the picture on the left (mark No. 9 on the next page) was found to have been removed after visiting the actual location, but its location was still recorded in the manual. In addition, this PCB radiates from the center of the circle. Within 300m, there are four student accommodations and they are located in the center of the geometric figure formed by these four apartments, which has a very high site selection value. So I will visit this area again to find this PCB.
These are the final nine locations selected and the corresponding addresses.
Among them, NO. 3, NO. 6, and NO.7 are located near the Main Library, with a large student flow and dense distribution of student apartments, so three sites are selected in a small area at the same time.
Below are pictures of the full location along with information, unfortunately, the NO.9 PCB appears to have been relocated when I went looking for it and was not found. Therefore it may be possible to cancel this location afterward.
