# CS-21: Step-free journey planning

Category: Travel & mobility
Level: Advanced
Suggested duration: 4–6 weeks

Original UXCharan practice scenario. Validate assumptions; do not present it as a commissioned client project.

## Problem
A fictional route planner optimises time but does not explain which parts of a journey are accessible or when information was checked. Explore how a traveller can compare routes and respond to an unavailable lift.

## People to learn from
Travellers who need step-free access

## Core scope
- Set access needs
- compare routes
- handle a disruption

## Research questions
- Which journey details determine feasibility?
- How do travellers verify access information?

## Edge cases
- Unknown station access
- lift unavailable

## Specific artefact
An accessibility data model and disruption flow

## Evaluation question
Can users identify a viable route and recognise unverified information?

## Work to share
Problem and role; anonymised evidence; alternatives and rationale; task flow; prototype; accessibility considerations; testing findings; revisions and honest limitations.
