Development of an isochrones visualisation app

Installation steps

OpenTripPlanner server installation

  • Clone the Github repository (uses git-lfs)

  • Verify that you have java8 (not compatible java9)

  • Then open a console and write (otp directory is the directory where the jar file is: [...]\app_iso\otp):

cd [path/to/otp/directory]
java -Xmx6G -jar otp-1.2.0-shaded.jar --router Paris --graphs graphs --server
  • Then wait until you see "Grizzly server running" (can take a couple of minutes depending of you computer specs)
  • You can check if OTP is ready here: http://localhost:8080 (you must see a map and the possibility to measure accessibility from a point to another stop)

Running the Bokeh app

  • Python libraries needed: => See requirements.txt file
  • If you want to install all this libraries without difficulties, we recommend to donwload and install Anaconda but you can also install these via pip (not recommended)
  • Once done, go in the root directory and open a console and run:
bokeh serve code
  • Your console should show something like:
018-04-20 19:11:59,045 Starting Bokeh server version 0.12.13 (running on Tornado 4.5.3)
2018-04-20 19:11:59,048 Bokeh app running at: http://localhost:5006/code
2018-04-20 19:11:59,049 Starting Bokeh server with process id: 70796
  • Then open http://localhost:5006/code in your browser. Wait a minute (this app is not really optimized for the moment and could take time for the first run)

  • That's it.
