The diagram illustrates the interaction between the disabled user and the system during the route planning process.
It shows the main user actions and the system functionalities required to generate an accessible route.
The purpose of this diagram is to clearly define system boundaries and identify the responsibilities of both the user and the system.
- The user must be logged into the system.
- The user has a registered account.
- The system has access to accessibility-aware route data.
- The user provides valid start and destination locations.
