Description
Divide nonnegative safe-integer intersectionCount by positive areaSquareKilometers.
Urban indicators compare counts or areas within a defined study boundary. Changing the denominator, the counted units, or whether a share is expressed as a fraction changes the meaning even when the arithmetic is correct.
Divide nonnegative safe-integer intersectionCount by positive areaSquareKilometers.
When to use this tool
Use Block Intersection Density Input when you need a reproducible density or share using an explicitly chosen study boundary and denominator.
How to use the tool and how it works
- Enter intersectionCount, areaSquareKilometers. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read intersectionsPerSquareKilometer. Use the output convention below.

| Input field | Meaning and units | Accepted input |
|---|---|---|
| intersectionCount | Intersection Count | Required. Safe integer; minimum 0. |
| areaSquareKilometers | Area Square Kilometers | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| intersectionsPerSquareKilometer | Intersections Per Square Kilometer | Required. Finite number. |

}Limitations and assumptions
- The denominator is explicitly square kilometers; intersection definition, boundary treatment, and road-network topology are supplied externally.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Document the data definitions and compare several planning indicators rather than treating one ratio as a design verdict.
