Optimized routing

An optimized route that reorders stops to minimize the distance and time required to visit all locations.

What is optimized routing?

Optimized routing, also known as the traveling salesperson problem (TRP), is the process of finding the best route to travel for a single vehicle when you need to stop at multiple destinations. Optimized routing differs from simple routing because it can reorder the sequence of stops to create the most efficient route possible, while minimizing the travel distance or travel time. Simple routing does not change the order of the stops you provide. Both simple and optimized routing take into consideration different restrictions such as speed limit, number of lanes, road conditions, and other barriers.

You can use optimized routing to:

Find the most efficient sequence of stops to multiple destinations.
Find the quickest and most effective path from an origin to multiple locations.
Generate driving directions in multiple languages.

How optimized routing works

The typical workflow for creating an optimized route is to:

Define the origin, stops, and destination.
Define the type of travel for the route.
Set the findBestSequence parameter to true. Unless specified, the first and last stops you provide will be kept.
Access the routing service to find the route features and directions.

How to navigate a route

Once you have a route, if you want to use your current device's location to track progress and provide navigation instructions (voice guidance) as you traverse the route, the best way to accomplish this is with the ArcGIS Maps SDKs for Native Apps.

URL requests

You can find a route and directions by making an HTTPS request to the routing service solve operation or by using client APIs. Specify the origin, destination, and optionally, additional parameters to refine the results with directions. Some of the most common parameters are described provided below.

Request limits

Limit	Direct	Job
Maximum number of stops	150	10,000

Maximum number of street features intersected by polygon barriers:	2,000	2,000

Force hierarchy beyond a straight-line distance of: (If the straight-line distance between any stops is greater than the limit shown here, the analysis uses hierarchy, even if the `travel_mode` defines not to use hierarchy.)	50 miles (80.46 kilometers)	50 miles (80.46 kilometers)
Maximum snap tolerance: (If the distance between an input point and its nearest traversable street is greater than the distance specified here, the point is excluded from the analysis.)	12.42 miles (20 kilometers)	12.42 miles (20 kilometers)

Code examples

Direct: Find an optimized route to restaurants

In this example, you find the best delivery route for ten restaurants in downtown San Diego. The default travelMode is driving time by vehicle, but you can use walk or trucking travel modes as well. The startTime is set as now, which sets the route departure time as the current time and the service will use the current traffic conditions. The findBestSequence parameter is set to true so that the service reorders the stops to generate the best route sequence.

Find an optimized route for ten stops.

Job: Find an optimized route for a truck delivery

In this example, you use a job request to find the best route sequence for 36 stops for a delivery truck for an area around San Diego. The travel_mode is set to find the trucking time and the reorder_stops_to_find_optimal_routes parameter is set to true so that the service reorders the stops and creates the best sequence for the delivery route.

Find an optimized route for a truck delivery with 36 stops.

REST API

Unlike Direct request type which allows you to make a request and get back all the results in the response, when working with a Job request type, you need to follow a three step workflow:

Make the submitJob request with the appropriate request parameters to get a job id.
Using the job id, check the job status to see if the job completed successfully.
Use the job id to get one or more results.
