Class AccessibilityChecker

java.lang.Object

org.episteme.social.architecture.AccessibilityChecker

public final class AccessibilityChecker
extends Object

Analytical tool for checking architectural compliance with accessibility standards such as ADA, EN 17210, and ISO 21542. It provides automated audits for door widths, corridor clearance, ramp slopes, and maneuvering spaces.

Method Details

checkDoorWidth

public static Optional<AccessibilityChecker.AccessibilityIssue> checkDoorWidth(Quantity<Length> width,
 String doorId)

Checks if a door's clear opening width meets the minimum requirement.

Parameters:

width - the measured width of the door opening

doorId - identifier for the door

Returns:

an Optional containing an issue if non-compliant

checkCorridorWidth

public static Optional<AccessibilityChecker.AccessibilityIssue> checkCorridorWidth(Quantity<Length> width,
 String corridorId)

Checks if a corridor's width provides sufficient clearance for wheelchair passage.

Parameters:

width - the measured width of the corridor

corridorId - identifier for the corridor

Returns:

an Optional containing an issue if non-compliant

checkRampSlope

public static Optional<AccessibilityChecker.AccessibilityIssue> checkRampSlope(Quantity<Length> rise,
 Quantity<Length> run,
 String rampId)

Checks if a ramp's slope exceeds the maximum allowed grade.

Parameters:

rise - the vertical height increase

run - the horizontal length

rampId - identifier for the ramp

Returns:

an Optional containing an issue if the slope is too steep

checkTurningSpace

public static Optional<AccessibilityChecker.AccessibilityIssue> checkTurningSpace(Quantity<Length> diameter,
 String spaceId)

Checks if a defined space provides enough room for a 180-degree wheelchair turn.

Parameters:

diameter - the diameter of the circular maneuvering space

spaceId - identifier for the space

Returns:

an Optional containing an issue if the space is too small

checkReachHeight

public static Optional<AccessibilityChecker.AccessibilityIssue> checkReachHeight(Quantity<Length> height,
 String controlId)

Checks if operable parts (switches, handles) are within the required vertical reach range (e.g., 38cm to 122cm).

Parameters:

height - the height of the control from the floor

controlId - identifier for the control

Returns:

an Optional containing an issue if out of reach

fullAudit

public static List<AccessibilityChecker.AccessibilityIssue> fullAudit(Map<String, Quantity<Length>> doorWidths,
 Map<String, Quantity<Length>> corridorWidths,
 Map<String,double[]> ramps,
 Map<String, Quantity<Length>> turningSpaces)

Conducts a full accessibility audit on multiple architectural elements.

Parameters:

doorWidths - map of door IDs to their widths

corridorWidths - map of corridor IDs to their widths

ramps - map of ramp IDs to their [rise, run] values

turningSpaces - map of space IDs to their turning diameters

Returns:

list of all detected accessibility issues sorted by severity
