Connect Origins to Destinations

Connect Origins to Destinations The Connect Origins to Destinations tool uses Esri Service Areas to measure the time or distance between pairs of points using straight lines or travel modes.

Terminology

TermDescription

Geodesic

Refers to a line drawn on a sphere. A geodesic line drawn on the globe represents the curvature of the earth's geoid.

Euclidean distance

A straight-line distance as measured on a flat surface (that is, a Cartesian plane).

Examples

  • A department store with a rewards program wants to know how far its patrons are traveling to shop. An analyst uses the Connect Origins to Destinations tool to find the travel distance between each patron (using ZIP Codes for location) and the store.
  • An elementary school teacher is planning a class trip and has assembled a short list of some possible destinations. The final decision will be based in part on how long it will take to travel to the destination. The Connect Origins to Destinations tool can be used to measure the drive time between the school and each of the possible trip locations.
  • A biologist is studying site fidelity in a migratory species of song bird. During the first year of the study, all of the nesting pairs were tagged and the location of their nests were recorded. In the second year of the study, the biologist went back to the study area and recorded the coordinates of the new nest locations for the returning birds. The Connect Origins to Destinations tool can be used to find the straight line distance between nesting sites in the first and second year for each bird.

Usage notes

Two input point layers are required: one with the origins and one with destinations. The connections between origins and destinations are summarized in the following table.

Pairs of origins and destinations will be connected using matching ID fields. Each layer must have the same number of features, and ID fields must have unique values within each layer.

Origins and destinations can be connected using a line distance or one of several travel modes. Some travel modes have an option for using traffic conditions. When traffic conditions are used, they may be based on live conditions or typical conditions for a specified day of the week and time. Live traffic conditions can be offset up to 12 hours from the current time. Times for typical conditions can be set by 15-minute intervals for the entire day and night.

Travel modes can be configured by the administrator of your organization. The administrator can also add new travel modes or remove travel modes that are not necessary for your organization. The default distance measure will be in Miles or Kilometers, depending on the Units setting in your profile.

Travel ModeDescriptionSpecifications

Walking Time Walking Time

Follows paths and roads that allow pedestrian traffic and finds solutions that optimize travel time. The walking speed is set to 5 kilometers per hour.

Walking speed is set at 5 kilometers (3.1 miles) per hour. The walking speed can be configured by the administrator of your organization.

Rural Driving Distance Rural Driving Distance

Models the movement of cars and other similar small automobiles, such as pickup trucks, and finds solutions that optimize travel distance. Travel obeys one-way roads, avoids illegal turns, and follows other rules that are specific to cars but does not discourage travel on unpaved roads.

None

Travel obeys one-way roads, avoids illegal turns, and follows other rules that are specific to cars. Dynamic travel speeds based on traffic are used where it is available when you specify a start time.

Use traffic is unchecked by default. The driving speed will be based on historical and live traffic data.

Traffic can be based on live conditions or typical conditions for a specified day of the week and time.

Trucking Time Trucking Time

Models basic truck travel by preferring designated truck routes and finds solutions that optimize travel time. Routes must obey one-way roads, avoid illegal turns, and so on.

Follows rules applicable to heavy trucks.

The trucking speed will be based on either historical average speeds for automobiles or the posted speed limits for trucks, whichever is smaller.

The output layer contains route lines including measurements between each origin and destination.

If Use current map extent is checked, only the features that are visible within the current map extent will be considered in the analysis. If unchecked, all features in the input layer will be considered, even if they are outside the current map extent.

Click Show Credits before you run your analysis to check how many credits will be consumed.

Limitations

  • Inputs can have no more than 5,000 points.
  • You must be granted the network analysis privilege to use travel modes.
  • The maximum number of route layers that can be created is 1,000. If the result contains more than 1,000 routes and Include route layers is checked, the tool will only create the output feature service.

How Connect Origins to Destinations works

The Connect Origins to Destinations tool uses a geodesic method when finding features with a straight-line distance, rather than a Euclidean method. Geodesic lines account for the actual shape of the earth (an ellipsoid, or more properly, a geoid). Distances are calculated between two points on a curved surface (the geoid) as opposed to two points on a flat surface (the Cartesian plane).

The Live traffic option uses the current time as the departure. The traffic speed is predicted for the trip using live speeds, historical speeds, and current events, such as weather.

When typical conditions for a day of the week and time are being used, the travel speeds are based on historical speeds averaged across 5-minute intervals for the entire week. The selected time will correspond to local time in the time zone that your data is in.

When either traffic condition is used, the Connect Origins to Destination tool will take into consideration the changing traffic conditions based on elapsed time from departure.
