Accessibility Data Model

Overview

This data model captures accessibility features at metro and bus stations, focusing on lifts/elevators and their mapping to gates, platforms, concourses, and other station elements. The goal is to standardise how accessibility information is collected, stored, and shared for inclusive transit planning and real-time passenger information.

Key Entities & Fields

1. Gate to Lifts Mapping

• station_id: Unique identifier for the station
• station_code: Short code for the station
• station_name: Name of the station
• station_type: Type of station (e.g., Elevated, Underground)
• type: Type of asset (e.g., Gate, Lift)
• name: Name/identifier of the gate or lift
• location: Description of location (e.g., Towards Parking, Towards Colony)
• linked_options: Asset(s) linked to this gate (e.g., Lift No. 3)

Example:

station_id	station_code	station_name	station_type	type	name	location	linked_options
72	DSG	DILSHAD GARDEN	Elevated	Gate	Gate No. 1	Towards Parking	Lift No. 3
72	DSG	DILSHAD GARDEN	Elevated	Gate	Gate No. 2	Towards Dilshad Colony	Lift No. 3

2. Lift to Platforms Mapping

• station_id: Unique identifier for the station
• station_code: Short code for the station
• station_name: Name of the station
• station_type: Type of station (e.g., Elevated, Underground)
• type: Type of asset (Lift)
• name: Name/identifier of the lift
• location: Description of location (e.g., Concourse to Platform)
• linked_options: Asset(s) linked to this lift (e.g., Gate No. 1, Platform 2, Concourse)

Example:

station_id	station_code	station_name	station_type	type	name	location	linked_options
72	DSG	DILSHAD GARDEN	Elevated	Lift	Lift No. 3	Ground to Concourse	Gate No. 1
72	DSG	DILSHAD GARDEN	Elevated	Lift	Lift No. 1	Concourse to Platform	Platform 2
72	DSG	DILSHAD GARDEN	Elevated	Lift	Lift No. 1	Concourse to Platform	Platform 1
