OpenTripPlanner server for Python

This package uses OpenTripPlanner to run network analysis such as shortest path, Catchment isochrone, and Origin-Destination Matrix. It requires an OTP server running locally on your machine.

Below briefly explains how to set up OTP, and how to use the scripts.

Setting up OTP server

To use OTP API it is necessary to setup OTP server. Here is a guide:

Install Java

OTP is written in Java. It is necessary to install download and install 64-bit Java Runtime Environment (not 32-bit). This can be downloaded here:

https://java.com/en/download/manual.jsp

Download OTP

The OTP can be downloaded in the executable .jar file format. The version I used for this repo is otp-1.3.0-shaded.jar. This can be downloaded here:

https://repo1.maven.org/maven2/org/opentripplanner/otp

Download network files

To use OTP for PT network analysis we need an Open Street Map (OSM) file of the street network and a General Transit Feed Specification (GTFS) for the PT data.

The OSM can be downloaded from:

https://www.openstreetmap.org

The GTFS can be downloaded from:

https://transitfeeds.com

Running the OTP server

To run the OTP sever, put the OSM, GTFS and OTP .jar files into a folder (e.g. D:\otp) and use the following commands to build a routable graph.

java -Xmx4G -jar otp-1.3.0-shaded.jar --build D:\otp --inMemory

The 4 in the -Xmx4G refers to how much memory should be allocated to the build.

Check out http://localhost:8080/ to test if it's routing properly.

Running the Scripts

Now you can open Python and start using the scripts. First import the package {.sourceCode .python}import pyotp as otp There are four functions in my script:

1. route: This function allows to find the best route between a pair of locations. Supported modes include CAR, BUS, FERRY, RAIL, TRANSIT, WALK, BICYCLE. You can use a combination of modes.

2. service_area: This function creates an isochrone of the catchment area for any points on the network.

3. od_matrix: This function creates a matrix of origin-destination routes.

An example for each of these functions can be found in ipynb/examples.ipynb

• This package is experimental.
• There are no tests written yet.
• I welcome contributions from anyone and everyone.
