Transit Stop LCD Displays: What to Put in the Passenger Information Brief
At a transit stop, begin the display brief with the passenger's question: is this the right stop, which service should I use, and what information is available about the next departure? Define those tasks before selecting a screen or discussing a data connection.
This guide helps procurement teams and integrators organize a passenger information brief. It does not describe an existing JIAMIAI LCD installation or confirm live data integration, remote monitoring, accessibility compliance or other product capabilities.
Identify the stop and the passenger task
Ask the transport operator to approve the stop name, identifier, direction of travel and route information that should appear. Record how this information relates to the physical stop signs and other passenger instructions.
List the tasks the display must support. For example, a passenger may need to confirm the route destination, distinguish the direction of travel or find a service-change notice. Identify the essential message for each task rather than treating every available data field as necessary content.
Separate scheduled information from predictions
For every proposed information item, ask who supplies it, who approves it and how it reaches the display system. Record whether a displayed time comes from a published schedule, an updated prediction or a manual notice. Ask the operator to approve how that distinction is communicated to passengers.
- Who owns the approved source and authorizes its use?
- Which stop and route identifiers must be mapped?
- What data format, access arrangement and integration work are required?
- Who investigates a mismatch between the source and the visible message?
- Which functions are included in the actual player and software proposal?
Do not assume that a display described as a transit format includes a particular feed, data service or software licence. Ask the supplier to confirm the proposed integration scope in writing.
Define when information is no longer usable
Ask the operator to set the rules for information freshness. The brief should say how the system identifies an outdated item, what should be removed and which approved message replaces it. Avoid choosing a universal expiry period without the operator's requirements.
Describe the expected behavior when a source stops updating, provides incomplete information or cannot be reached. A general service notice may be an appropriate fallback if approved by the operator; retaining an old prediction should not be accepted by default.
Use the content and offline planning guide to distinguish loss of connectivity from a stale source. Agree tests for the proposed configuration and record what has actually been demonstrated.
Review the display from passenger positions
Mark candidate locations on the site survey. Include the waiting area, normal approach and relevant seated and standing observation points. Coordinate the review with the operator so it does not obstruct passenger movement or boarding.
Test the longest expected route name, destination text and an approved disruption notice. Check orientation, missing characters, cropped content and the time available to read changing messages. Use the readability checklist to record positions, conditions and findings.
Have the responsible project specialists define any applicable accessibility and passenger-information requirements. A general layout review is not evidence of compliance.
Assign responsibility for service notices
Name the people who create, approve, publish and remove manual notices. Include a backup contact and the process for an urgent correction. Record each notice's target stops, start and end time, time zone and replacement content.
Ask how the operator will confirm that the intended stop received the message. Clarify what any delivery status or playback record proves, and include an agreed visual check in acceptance. Keep credentials separate from general content instructions.
Test the information chain before rollout
Use approved test data and coordinate any interruption with the responsible team. Review the full route from the source through the player to the visible screen.
- Confirm the correct stop, route and direction mapping.
- Show the distinction between scheduled and predicted information where applicable.
- Test the agreed stale-data and unavailable-source scenarios.
- Publish, replace and expire an approved manual notice.
- Verify the visible result from the agreed passenger positions.
- Record unresolved items, owners and repeat-test requirements.
Keep untested conditions visible in the acceptance record. For several locations, use a pilot plan to identify which differences need additional assessment.
