HOW TO
Set up conversions for a drive-time attribute in Network Analyst
Summary
In a network dataset, drive-time attributes are used to measure and model impedances, such as travel time. In many cases, street networks have the necessary elements for a drive-time field. The instructions provided describe how to calculate a drive-time attribute in ArcGIS Network Analyst.
Procedure
To calculate a drive-time cost attribute in ArcGIS Network Analyst, the following data are required:
• Distance units (in miles, feet, or meters)
Add a new double field for the street data using the Field Calculator and one of the following formulas based on the street's units of length.
Note:
In most cases, the Shape_Length attribute can be used as the length and the units are defined by the projection.
The following formulas are based on street distance:
Meters
[Length_Field_Meters] / 1609 * 60 / [Speed_Field_MPH]
Kilometers
[Length_Field_Kilometers] / 1.609 * 60 / [Speed_Field_MPH]
Feet
[Length_Field_Feet] / 5280 * 60 / [Speed_Field_MPH]
Miles
[Length_Field_Miles] / [Speed_Field_MPH]
