Toronto TTC Streetcar Data Mining Project

Combining Toronto Open TTC Data with seperate weather data to mine frequent patterns that cause delays.

Data Sets Used

https://toronto.weatherstats.ca/download.html - Download Climate Daily/Forecast/Sun- Toronto Weather Data https://open.toronto.ca/dataset/ttc-streetcar-delay-data/ - Download All TTC StreetCar Delay Data

Data Pre-Processing

Weather data was downloaded for the same time frame as our streetcar delay data set. The two datasets were joined on their data. Daily snow,avg_wind_speed,avg_visibility,avg_hourly_temperature,rain was taken from the weather data set. This combined dataset was used to create categories for Rain,Snow,Wind,Visibility,Time of Day, Month of Year, Day of Week, Route number, Direction of StreetCar Travel, Delay amount,Temperature.

Frequent Pattern Mining

Random Forest Regression

One Hot Encoded FinalCategorizedData for the categorical variables. Used 40 estimators for the random forest ensemble Model had: Base line error of 10.62 minutes before training Mean Prediction Error of 3.335 minutes after training

Installing Dependencies

We use conda to manage dependencies, install conda from https://docs.conda.io/projects/conda/en/latest/user-guide/install/ if you do not have it. The code was tested on conda version 4.7.12.

Create the environment

  1. Open the Conda Prompt
  2. Run "conda env create -f environment.yml" using the environment.yml provided

Activate the environment

  1. Run "conda activate sjr-fall-2019-datamining-project"

This provides the dependencies needed for the python files.

Download datasets

Download the datasets from the links in the above section "Data Sets Used" and place them in a folder called 'datasets'. These should be the downloaded datasets and they should be named as such.

  • ttc-streetcar-delay-data-2014.xlsx
  • ttc-streetcar-delay-data-2015.xlsx
  • ttc-streetcar-delay-data-2016.xlsx
  • ttc-streetcar-delay-data-2017.xlsx
  • ttc-streetcar-delay-data-2018.xlsx
  • ttc-streetcar-delay-data-2019.xlsx
  • weatherstats_toronto_daily.csv

Running the code

You can recreate the processed datasets or just run the regressor and frequent pattern mining. Please make sure that a folder called 'datasets' exists with the datasets shown above, and a folder named 'processed_data' also exists. Both should be at the root level, on the same one as the python files.

Run the regression

  1. Run "python random_forest.py"

Run the frequent pattern mining

  1. Run "python mlxtend_test.py"

Recreate the processed datasets

  1. Run "python load_preproc.py"
  2. Run "python preprocess_data.py"
  3. Run "python Categorize_Data.py"
