What it is Filled

A structure at street level giving access to an underground railway (metro or subway) station, usually by stairs, escalators or lifts, often marked with the system's sign and sometimes housed in a kiosk or building.

Why it exists Filled

Let an agent describe subway entrances, their design, accessibility and identification, from transit authority sources.

Distinguishing features Filled

  • Many stations have several entrances, each with its own identifier.
  • Accessibility varies: some entrances have lifts, many only stairs.
  • Some entrances are heritage-listed, such as the Art Nouveau Guimard entrances in Paris.

Dimensions vary per entrance and are recorded in transit data.

Recognition required Filled

  • Stairs down from the pavement with a metro sign, such as the Paris Metro Guimard entrances
  • A stairway or escalator opening at street level, with signage and sometimes a canopy or kiosk.

Capabilities and actions required Filled

  • explain types and features
  • explain accessibility features
  • point to transit authority data on entrances
  • describe notable designs

Hazards and failure modes required Filled

  • Flooding of stations through entrances
  • Crowding and falls on stairs

Standards and interfaces required Filled

  • Accessibility law (such as the ADA in the US and EU accessibility rules)
  • Fire safety and egress codes such as NFPA 130

Context of use required Filled

  • Access between the street and underground stations.
  • stair entrance
