Simpler Route Optimisation

Simpler Route Optimisation#

Tarot Routing - Route Optimisation API

Quickstart#

1. Auth#

If you don’t have an account already, Sign Up for one or reach out to us at info@tarotanalytics.com

Then, get your Access Token:

URL='https://api.route.optimiser.app/api/auth/token'
HEADERS='Content-Type: application/json'
BODY='{
        "email": "your_email_address",
        "password": "your_password"
}'

RESP=$(curl "$URL" -H "$HEADERS" --data "$BODY")

# jq is a command line utility for parsing JSON
# you can install it with `apt install jq` or equivalent.
# The idea is just to get the `access_token` from the JSON response.
TOKEN=$(echo $RESP | jq -r .access_token)

2. Request Body#

Second, let’s prepare a JSON request body made up of Jobs, Drivers and Settings representing your routing problem:

Request Body ex1.json#
{
  "drivers": [
    {
      "uid": "drvid1",
      "shift_start": 8,
      "shift_end": 17,
      "location": {"lat": -33.867798, "lon": 151.166256}
    }
  ],
  "jobs": [
    {
      "uid": "uid1",
      "duration": 2,
      "location": {"lat": -33.849489, "lon": 151.127482}
    },
    {
      "uid": "uid2",
      "duration": 2,
      "location": {"lat": -33.880661, "lon": 151.183096}
    },
    {
      "uid": "uid3",
      "duration": 2,
      "location": {"lat": -33.913168, "lon": 151.262267}
    }
  ],
  "settings": {}
}
Here’s one I prepared earlier#
wget https://docs.opt.route.optimiser.app/_static/ex1.json

3. Optimise#

You can access the Route Optimisation API by sending a POST request to the Synchronous Route Optimisation API endpoint.

TOKEN={your_tarot_routing_token}
curl https://opt.route.optimiser.app/v0.40/vrp \
      -H "Authorization: Token $TOKEN" \
      -H "Content-Type: application/json" \
      --data "@ex1.json"

4. Response#

A few seconds later, you’ll receive a response:

Response Body#
{
    "runs": [
        {
            "driver": {
                "uid": "drvid1",
                "shift_start": "08:00:00",
                "shift_end": "17:00:00",
                "run": 1,
                "seq": 0,
                "location": {
                    "lon": 151.166256,
                    "lat": -33.867798
                },
                "end_location": {
                    "lon": 151.166256,
                    "lat": -33.867798
                }
            },
            "jobs": [

                    "uid": "uid1",
                    "duration": 120,
                    "eta": "08:09:45",
                    "etd": "08:11:45",
                    "run": 1,
                    "seq": 1,
                    "location": {

                        "lat": -33.849489
                    }
                },
                {
                    "uid": "uid2",
                    "duration": 120,
                    "eta": "08:24:12",
                    "etd": "08:26:12",
                    "run": 1,
                    "seq": 2,
                    "location": {
                        "lon": 151.183096,
                        "lat": -33.880661
                    }
                },
                {
                    "uid": "uid3",
                    "duration": 120,
                    "eta": "08:42:32",
                    "etd": "08:44:32",
                    "run": 1,
                    "seq": 3,
                    "location": {
                        "lon": 151.262267,
                        "lat": -33.913168
                    }
                }
            ]
        }
    ],
    "unserved_jobs": []
}

The runs element is a list of Runs. The first Object in each Run is the Driver. All Subsequent objects in that Run are the Jobs.

Any Jobs listed in unserved_jobs were not able to be served with the Drivers provided.
