poc-osrm

Introduction

This project is POC to make a frontend web application which has the routing map feature for Kansai region, Japan.

Openstreetmap and Open source routing machine (OSRM) are applied.

Web frontend

Setup backend

We need to setup the OSRM backend first. We setup according to osrm-backend project : https://github.com/Project-OSRM/osrm-backend

We are going to setup 2 profiles: car and bicycle. Ref: https://github.com/Project-OSRM/osrm-backend/blob/master/docs/profiles.md

  1. Download the Kansai region OSRM extract file:
wget http://download.geofabrik.de/asia/japan/kansai-latest.osm.pbf
  1. Copy the .pbf files into 2 profile files
cp kansai-latest.osm.pbf kansai-car.osm.pbf
cp kansai-latest.osm.pbf kansai-bicycle.osm.pbf
  1. For each profile, pre-process the extract data
docker run -t -v $(pwd):/data osrm/osrm-backend osrm-extract -p /opt/[profile].lua /data/kansai-[profile].osm.pbf
docker run -t -v $(pwd):/data osrm/osrm-backend osrm-partition /data/kansai-[profile].osrm
docker run -t -v $(pwd):/data osrm/osrm-backend osrm-customize /data/kansai-[profile].osrm
  1. Run HTTP server

Since we have different profiles, we need to expose different HTTP port for each profile.

For example:

docker run -t -i -p 5000:5000 -v $(pwd):/data osrm/osrm-backend osrm-routed --algorithm mld /data/kansai-bicycle.osrm
docker run -t -i -p 5001:5000 -v $(pwd):/data osrm/osrm-backend osrm-routed --algorithm mld /data/kansai-car.osrm
  1. Test the local routing endpoint
http://127.0.0.1:5000/route/v1/bicycle/135.525966,34.687607;135.429018,34.654739?steps=true
http://127.0.0.1:5001/route/v1/car/135.525966,34.687607;135.429018,34.654739?steps=true

You will get different routes for each endpoint.

In above example, it is routing from Osaka Castle, Osaka to Kaiyukan, Osaka

Note that the lat/log order is the reverse of those obtained from Google Map.

Setup frontend

Run locally

  1. Install packages

    yarn

  2. Build

    yarn run build

  3. Run the server

    yarn run start:prod

By Docker

  1. Build docker image
docker build -t poc-osrm:latest .
  1. Run docker
docker run -p 3000:3000 poc-osrm:latest

Then you can run the frontend web by http://localhost:3000/

Another option

You can also mount the host directory to container directory, for faster development.

docker run -v $(pwd):/var/www/app -p 3000:3000 poc-osrm:latest
