Route and directions

A route and turn-by-turn directions for two points created with the routing service

What is routing?

Routing is the process of finding the best path from an origin to a destination in a street network. Routing takes into consideration many different data parameters in the street network such as speed limit, number of lanes, and time of day. Routing can also take into consideration other real-time data such as road conditions, accidents, and other barriers.

You can use routing to build applications that:

  • Find the shortest path from an origin to a destination
  • Find the quickest path to multiple destinations
  • Determine the best sequence to visit multiple destinations
  • Generate driving directions in multiple languages

How routing works

The typical workflow for creating a route is to:

  1. Define the origin, and stops, and destination.
  2. Define the type of travel for the route.
  3. Call the service to find the route features and directions.

You can create simple or optimized routes using the routing service.

  • A simple route is the shortest path between stops.

  • An optimized route is the most efficient path between stops.

To create an optimized route, you will need to use the findBestSequence parameter. Using the parameter will result in the stops being reordered to return the most efficient path between them.

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 Runtime APIs.

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.

Examples

Direct: Find a route and directions

In this example, use the routing service to find a route between a set of stops that accounts for current traffic conditions and generate driving directions in Spanish.

To find a route, you need to define at least two stops to visit. The default travelMode is driving time by vehicle, but you can use walk or trucking travel modes as well. It is always good to provide the startTime to get the best results. In this example, we specify startTime as now which sets the route departure time as the current time and also indicates to the service that the route should use the current traffic conditions. We also set the directionsLanguage to generate driving directions in our language of choice.

The response contains a set of ordered stops to visit, the route segments, and turn-by-turn text directions.

Job: Find multiple routes

In this example, you will find the travel time and travel distance for multiple routes operated by a long-haul logistics company.

  • We group a pair of stops that define a route by assigning them a unique RouteName value. This allows the service to find all the routes in a single request as compared to sending multiple requests for each route, thus improving the overall performance.

  • We specify the Trucking Time travel_mode since we are finding routes for trucks and not cars.

  • Since we are only interested in finding the travel time and travel distance for our routes and do not need the route geometry, we set the route_shape to None.

  • We also do not need driving directions for our routes. So we set the populate_directions to false.

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:

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