Input polyline features
The input line features for which to calculate the density.
Numeric field denoting population values (the number of times the line should be counted) for each polyline.
Values in the population field can be integer or floating point.
The options and default behaviors for the field are listed below.
Output cell size
The cell size of the output raster that will be created.
This parameter can be defined by a numeric value or obtained from an existing raster dataset. If the cell size hasn't been explicitly specified as the parameter value, the environment cell size value will be used if specified; otherwise, additional rules will be used to calculate it from the other inputs. See the usage section for more detail.

The search radius within which density will be calculated. Units are based on the linear unit of the projection of the output spatial reference.
For example, if the units are meters—to include all features within a one-mile neighborhood—set the search radius equal to 1609.344 (1 mile = 1609.344 meters).
The default is the shortest of the width or height of the output extent in the output spatial reference, divided by 30.
The area units of the output density values.
A default unit is selected based on the linear unit of the output spatial reference. You can change this to the appropriate unit to convert the density output. Values for line density convert the units of both length and area.
If no output spatial reference is specified, the output spatial reference will be the same as the input feature class. The default output density units are determined by the linear units of the output spatial reference as follows. If the output linear units are meters, the output area density units will be set to Square kilometers, outputting square kilometers for point features or kilometers per square kilometers for polyline features. If the output linear units are feet, the output area density units will be set to Square miles.
If the output units is anything other than feet or meters, the output area density units will be set to Square map units. That is, the output density units will be the square of the linear units of the output spatial reference. For example, if the output linear units are centimeters, the output area density units will be Square map units, which will result in square centimeters. If the output linear units are kilometers, the output area density units will be Square map units, which will result in square kilometers.
The available options and their corresponding output density units are the following:
