actransit-map

A Jupyter notebook repository for plotting real-time AC Transit bus coordinates on a map.

Introduction

metro_mapping.ipynb and gif_generator.ipynb complement each other in:

1. Gathering images of real-time bus locations in various regions in the San Francisco East Bay (map_dimension).
2. Converting these images to a gif.
   
   

Python Setup

This script requires Python 3.5 and above. Please see requirements.txt for required Python libraries. Clone this repository and use pip to install the necessary libraries into your conda environment, like this:

pip install -r requirements.txt

You will have to install two additional libraries to properly execute export_png() from the bokeh.io module:

1. pip install selenium
2. conda install -c conda-forge phantomjs

Running the Notebooks

Run metro_mapping.ipynb entirely and execute main() to start collecting images (which will accumulate in the ./map_figs directory).
main() will run indefinitely. When you are satisfied with the accumulated images, click the square button at the top of the notebook to interrupt the kernel:

Then, run the entirety of ```gif_generator.ipynb```. Provide an appropriate name for your gif when prompted in ```main()```. This will create a .gif file of your .png images in the ```./gif_files``` directory.

Notes

A .png file will range from 200kb - 240kb in size. Accumulating hours of images can lead to a large .gif file. For example, 12 hours of images could lead to a ~ 1 GB gif image. Please let me know if you have questions.
