Create Drive-Time Areas

Create Drive-Time Areas The Create Drive-Time Areas tool uses Esri Service Areas to calculate the area that can be reached within a specified travel time or travel distance along a street network based on travel mode.

Examples

  • A local reporter is working on a story about response times to fires in her city. She wants to determine how much of the city is within a four-minute drive-time of the city's fire stations in heavy and light traffic. She also wants to determine what the response time would be in the furthest-to-reach parts of the city.

    See the Investigating response times case study for the complete workflow.

  • A development company is planning to build a new retirement community and wants to learn more about the demographics in the area surrounding existing communities. The target demographics for the new retirement community will be based on the demographics within a 5-mile driving distance of the best performing community.

    See the Locating a new retirement community case study for the complete workflow.

Usage notes

The input is a single layer of points containing up to 1,000 features.

The drive-time area can be based on several different travel modes using time or distance as the measure. You can create multiple output areas by inputting each time or distance, separated by a space.

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.

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. When you specify a start time, dynamic travel speeds based on traffic are used where it is available, up to the legal truck speed limit.

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

Follows rules applicable to heavy trucks.

By default, the Create Drive-Time Areas tool will create overlapping areas when the travel areas from different points meet. The other options for overlapping areas are Dissolve or Split.

OptionDescription

Overlap Overlap

For any travel area that is on top of another travel area, the areas in common are kept.

Dissolve Dissolve

For any travel area that is on top of another travel area, the areas in common are combined.

Split Split

For any travel area that is on top of another travel area, the overlapping areas are split in the middle.

If Use current map extent is checked, only the features that are visible within the current map extent will be used to create drive-time- or drive-distance-based areas. If unchecked, all features in the input layer will be used, even if they are outside the current map extent.

Limitations

  • The Create Drive-Time Areas tool works with point features only.
  • The input layer can have no more than 1,000 points.
  • You must be granted the network analysis privilege to use Create Drive-Time Areas.
  • Travel times cannot exceed 5 hours (300 minutes).
  • Travel distances cannot exceed 300 miles (482.8 kilometers).
  • Traffic conditions are not supported in all regions. Check for coverage in your area using the ArcGIS Online Directions and Routing Services Coverage web map.
  • Travel mode availability is determined by your organization's administrator.
  • An error will occur if the tool takes more than 60 minutes to execute. If this error occurs, try rerunning the analysis with fewer input features.

How Create Drive-Time Areas works

The Create Drive-Time Areas tool uses the ArcGIS Online network analysis service as a street network. To find out more about the latest updates to the street network, see What's new in the network analysis services.

Service Areas use Dijkstra's algorithm to traverse a network. The service returns a subset of connected edge features that are within a specified travel distance or travel time. Travel areas are created by inputting the edges into a triangulated irregular network (TIN) data structure. The network distance along the lines serves as the height of the locations inside the TIN. Locations not traversed by the service area are put in with a much larger height value. An area-generation routine is used with this TIN to carve out regions encompassing areas in between the specified break values (travel time or travel distance).

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. If your data is in more than one time zone, the drive-time area will be generated for both time zones (for example, 8:00 a.m. eastern time and 8:00 a.m. pacific time). The Areas from different points parameter must be set to Overlap if your data is in more than one time zone.

When either traffic condition is used, the Create Drive-Time Areas tool will take into consideration the changing traffic conditions based on elapsed time from departure.

If you are trying to generate areas around points, lines, or areas with a straight-line distance rather than a street network, use the Create Buffers tool.

If you are trying to summarize features within a specified travel time or distance of your input layer, use the Summarize Nearby tool.

If you are trying to create enriched areas based on travel modes, use the Enrich Layer tool.

Note:

Traffic conditions are not available when using travel modes in the Enrich Layer tool.
