Generate Drive Time Trade Areas (Business Analyst Tools)

Summary

Creates a feature class of trade areas around point features based on travel time and distance.

Usage

  • This tool requires a locally stored dataset or a portal connection, such as ArcGIS Online.

  • You can create drive time rings that don't overlap using various travel modes.

  • When using the Remove Overlap parameter, limit your features to around 200-300 points. For larger site sets, you may have success by generating overlapping areas first then using the Remove Overlap (multiple) tool.

  • The Time of Day parameter is used to model output polygons based on historical traffic data at the specified day and time.

  • The ID Field parameter is used to create an attribute in the output that uniquely identifies each polygon and respective input point.

Parameters

Label Explanation Data type

Input Features

The input point feature layer.

Feature Layer

Output Feature Class

The output feature class containing the drive time polygons.

Feature Class

Distance Type

The method of travel that will be used for drive time calculation.

String

Distances

The distances that will be used for drive time calculations.

Double

Distance Units

(Optional)

The units that will be used for the distance values. The default value is miles.

String

ID Field

(Optional)

A unique ID field for existing facilities.

Field

Dissolve Option

(Optional)

Specifies whether overlapping or nonoverlapping service areas for a single location will be used when multiple distances are specified.

  • Overlap—Each polygon will include the area reachable from the facility up to the distance value. This is the default.

  • Split—Each polygon will include only the area between consecutive distance values.

String

Remove Overlap

(Optional)

Specifies whether overlapping concentric rings will be created or overlap will be removed from multiple locations in relation to one another.

  • Checked—Polygons will be split and the overlap between output features will be removed.

  • Unchecked—Output features will be created with overlap. This is the default.

Boolean

Travel Direction

(Optional)

Specifies the direction of travel toward or away from stores.

  • Toward stores—The direction of travel will be toward stores. This is the default.

  • Away from stores—The direction of travel will be away from stores.

String

Time of Day

(Optional)

The time and date that will be used when calculating distance.

Date

Time Zone

(Optional)

Specifies the time zone that will be used for the Time of Day parameter.

  • Time Zone at Location—The time zone in which the territories are located will be used. This is the default.

  • UTC—Coordinated universal time (UTC) will be used.

String

Search Tolerance

(Optional)

The maximum distance that input points can be from the network. Points located beyond the search tolerance will be excluded from processing.

This parameter requires a distance value and units for the tolerance. The default value is 5000 meters.

Linear Unit

Polygon Detail

(Optional)

Specifies the level of detail that will be used for the output drive time polygons.

  • Standard—Polygons with a standard level of detail will be created. This is the default.

  • Generalized—Generalized polygons will be created using the hierarchy present in the network data source to produce results quickly.

  • High—Polygons with a high level of detail will be created for applications in which precise results are important.

String

Input Method

(Optional)

Specifies the type of value that will be used for each drive time.

  • Values—A constant value will be used (all trade areas will be the same size). This is the default.

  • Expression—The values from a field or an expression will be used (trade areas can be different sizes).

String

Distance Expression

(Optional)

A fields-based expression used to calculate drive time.

SQL Expression
