This rule checks the accessible routes. The checking requires the accessible route modeled as a component. The rule can check the clear width of route and components such as doors, stairs, and ramps within the route. The rule checks also the connections from accessible route to the accessible spaces and accessible elevators.
The rule parameters are:
Accessible Route:
This filter is used to select route components to check.
-
Route Width Requirements: This defines the minimum clear width limits. The limits are checked for stair, ramp and door components that occur within the route. The minimum clear width is checked for route also.
Connecting Spaces:
-
Accessible Spaces: This filter is used to select spaces that are checked for accessibility. The rule checks the separation of the space from closest accessible route object. If the separation is less than the value of the "Maximum Allowed Gap Between Route and Connecting Spaces" parameter, then the space is considered accessible.
-
Accessible Elevators: This filter is used to select elevators that are checked for accessibility. The rule checks the separation of the elevator from closest accessible route object. If the separation is less than the value of the "Maximum Allowed Gap Between Route and Connecting Spaces" parameter, then the elevator is considered accessible.
-
Maximum Allowed Gap Between Route and Connecting Spaces: This defines the maximum allowed gap between an accessible space or accessible elevator and an accessible route.
Obstacles:
This filter is used to select the components that can be obstacles on an accessible route. The rule checks if the selected components obstruct an accessible route.
Maximum Allowed Obstruction Depth into Route: This defines the maximum allowed obstruction depth inside the accessible route. This parameter is used to allow obstacles to be partly inside the accessible route. For example, if the maximum allowed obstruction depth is set to 20cm and an object on the side of the route only penetrates 10cm into the route, then that object is not considered an obstacle.
Analysing the results:
The rule creates following types of issues:
-
Accessible route is too narrow
-
Stair is too narrow
-
Ramp is too narrow
-
Door is too narrow
-
Accessible space is not connected to any accessible route
-
Accessible elevator is not connected to any accessible route
-
Accessible routes are connected with stair and without ramp
-
Accessible route is obstructed
