Goal of the project: Given 2 datasets: Nodes (cal.cnode.txt): Edges (cal.cedge.txt): < End Node ID>

1. Draw the Nodes onto a California Map
2. Create a UI where if you click on an intersection point (node) it displays adjacent edges.
3. Click on "shortest path" button, click two points (nodes), and display 3 shortest paths from Node A to Node B

This project uses: Python 2.7 -Flask framework HTML/CSS/Javascript -Google Maps API

Preloading the map takes O(n). N is number of nodes. Since node:edge data preloaded into a python dictionary, (2) takes O(1). Shortest path uses Yens KSP algorithm; (3) takes approximately O(n^2)

To run the project:

1. Change nodedirectory, and edgedirectory in wazeApp.py, to the path on your local machine.
2. Change _directory_data in graph.py to /data/json on your local machine
3. Run wazeApp.py
4. Run the app in your browser at the appropriate address.
