sf_abm_vis

• Visualisation of the shortest path between origin-destination (OD) pairs
• Modification of the road network through screen clicking and visualising the new path based on the modified network

Preparation

• Install python3 and required packages through, e.g., pip3 install flask
• Install python-igraph. If you are using Mac, you can follow this SO link
• Get an access token from Mapbox and set environment variable in the terminal with export MapboxAccessToken=[your access token]

Running

• Start with the server python3 server.py
• Open a browser window and navigate to 127.0.0.1:5000. It may take 1-2 seconds for the shortest paths in undisturbed network to show
• Click on any point on the map (preferrably near an exisiting path) to simulate a local disruption. New paths will be calculated in the server and visualised in the browser
