We also want to make sure that the coffee shop is near a transit station, and has no Starbucks near it. As an included function, we will make sure that the crime concentration in the area is low, and the entire program must be carried out in Python.
As part of this article, we will check out the main steps involved in forecasting the best place for a coffee bar in Vancouver. We will likewise think about that the coffee shop is near a transit station, and has no Starbucks near it. Well, while at it, let us also add an additional feature where we make sure the criminal activity in the location is lower.
This covers the very first 2 steps required to get data from the internet, both manually and immediately.
Note: There are 530,653 records of criminal activity in this file.
Get criminal offense history for the last two years
Get places of all transit stations and Starbucks in Vancouver
Check all the transit stations that do not have any Starbucks near them
Get all the data relating to crimes near the filtered transit stations
Develop a grid of all possible coordinates around the transit station
Check criminal activity around each produced coordinate and show the leading 5 places.
We can get criminal offense history for the previous 14 years in Vancouver from here. This data is in raw crime.csv format, so we have to process it and filter out worthless data.
In this program, we will just utilize the type and coordinate of the crime. There are numerous criminal offense types, however we have actually classified them into three significant classifications namely;
This may seem full and very congested, so lets see a closeup image for future recommendations.
Now lets filter out all crime records and get just what we have an interest in, which implies the criminal offense near Transit stations. For that we will outline a location of specific radius around each of them to see the crimes. These are more than 110,000 criminal activity records.
To manage this, we can eliminate the duplicate values in criminal activity coordinates and those which are too near each other ~ 1m. Doing so, we are entrusted simply 816 Thefts, 2,654 Break ins, and 8,234 Mischiefs around each created coordinate.The precision will not be affected much but the time and computational resources required will be minimized a lot
We can add it to a list if none of the Starbucks are within that specific Transit Stations area. At the end, we have a list of all Transit areas with no Starbucks near them. There are a total of 6 Transit Stations with no Starbucks near them.

As we have all the information required, now moving to the next step. We require to get to the transit Station places that have no Starbucks near them. For that we can develop an area of particular radius around each Transit Station. Inspect all Starbucks areas with respect to them, whether they are within that area or not.
There may be numerous methods to solve this problem, however the one I used in this program is that I will create a grid of all possible places (coordinates) in the location of 1 km radius around each situated transit station.
Now that we have all the Transit Stations that do not have any Starbucks near them and likewise the crime near all Transit Stations. Lets utilize this information and get crime near the situated Transit Stations. These have to do with 44,000 criminal activity records.

Enter and break.
These all crimes can be outlined on Graph as displayed below.
For area prediction we require to compare each coordinate with crime collaborates. As the algorithm has to check for ~ 7,000 Thefts, ~ 19,000 Break ins, and ~ 17,000 Mischiefs around each generated coordinate.
Filter out Coordinates having Theft near 1 kmWe get 122,000 collaborates with no Thefts (Below merged 1000 to 1).
Now lastly, we have all the prerequisites and lets get to the main task at hand, predicting the very best coordinate for the coffee bar.
Theft (red), Enter and break (orange) and Mischief (green).
Filter out Coordinates having Break Ins near 200mWe get 8000 coordinates with no Thefts (Below merged 1000 to 1).
The Starbucks data is present here, we can scrape it easily and get the locations of all the Starbucks in Vancouver. We simply require the Starbucks that is near transit stations, so well filter out the rest. There are an overall 24 Starbucks in Vancouver, and 10 of them are near Transit Stations.
Examining Crime near Generated coordinates.
Filter out Coordinates having Mischief near 200mWe get 6000 coordinates with no Thefts (Below merged 1000 to 1) Now that we have 6 Coordinates of best places that have actually travelled through all the restrictions, we will buy them.To buy them, we will inspect their distance from the closest transit place. The closest will be on top of the list as the best possible location, then the 2nd and so on. The generated List is;.
The option to this is to develop a coordinate for each 10 m area, this results about 10,000 coordinate per km. For the above pointed out number of crimes, the approximated procedures will be several Billions. That would significantly decrease the time, however is still not less.
This may seem appropriate in the beginning glance, however the points are overlapping due to abundance, so we can create various lists of criminal offenses based upon their types.
We can get the collaborates of all Transit Stations in Vancouver from here. This dataset has all coordinates of fast transit stations in 3 transit lines in Vancouver. There are a total of 23 of them in Vancouver, we can then utilize it for additional processing.
I produced 1 coordinate for every m, this resulted in 1000,000 coordinates in every km. This is a substantial number, and for the 6 situated Transit stations, it ends up being 6 Million. Since computers can manage such data in a couple of seconds, it may not seem much at very first glimpse.
Keep in mind: Other than the coordinates of Transit Stations and Starbucks, we likewise need collaborates and type of the criminal offense.
Now that we have all the locations, we will start some processing on it and check each coordinate versus some constraints. That are respectively;.
We can get the coordinates of all Transit Stations in Vancouver from here. Now lets filter out all criminal activity records and get just what we are interested in, which suggests the criminal offense near Transit stations. Now that we have all the Transit Stations that dont have any Starbucks near them and likewise the criminal offense near all Transit Stations. Lets get and use this details criminal activity near the located Transit Stations. Filter out Coordinates having Mischief near 200mWe get 6000 collaborates with no Thefts (Below merged 1000 to 1) Now that we have 6 Coordinates of finest places that have passed through all the restraints, we will buy them.To purchase them, we will examine their distance from the closest transit location.
