What the data for this category looks like
Data for public transit service inquiry and response primarily comes from public transit operation scheduling systems, official operation logs, and real-time passenger flow monitoring platforms. Core data fields include route number, stops served, first and last departure times, real-time arrival delay duration, fare standards, and service complaint channels. Data update cadence falls into two categories: real-time data such as vehicle location and arrival time is synced every 30 seconds; static data such as route adjustments and stop renames is updated on the day the change takes effect. Data documents are stored as structured tables, with field names following national transportation industry standards. Units include minutes, yuan, kilometers, and others.
What constraints these characteristics impose on forms and interactions
The real-time update cadence and static field characteristics of public transit data impose clear constraints on the forms and interactions link. Real-time data synced every 30 seconds requires route selection and arrival query modules in forms to pull the latest data sources in real time, to avoid displaying discontinued routes or outdated arrival information. Static fields such as route numbers and stop name changes take effect the same day, so forms must support administrators to batch update optional option libraries, and validate input content against current valid data when a user submits. The minute-level precision requirement of real-time data restricts form input boxes to only accept positive integers or values with minute units, and automatically complete the unit identifier. High-frequency inquiry scenarios require forms to preset quick options such as route query and shift consultation, while supporting free text input to cover special inquiry needs.
How to configure
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
formInput | Preset 10 high-frequency public transit inquiry options + free input box | High-frequency public transit inquiry scenarios include route query, stop transfer, and shift time. Preset options reduce user input costs, while free input covers special inquiry needs |
userSelect | Drop-down menu loads latest route list with delay ≤30 seconds | Real-time public transit data is synced every 30 seconds. Drop-down menu sync frequency must match data update cadence to avoid displaying discontinued or outdated routes |
| Form input validation rules | Only accept positive integers or values with minute units, automatically complete units | Real-time arrival delay data has minute-level precision. Input format and unit must match business data specifications |
| Static option batch update | Automatically sync official operation log data at 00:00 daily | Static public transit data such as route adjustments and stop renames takes effect the same day. Daily sync ensures the option library stays consistent with official data |
| Interaction timeout setting | 600 seconds | Public transit inquiries may involve multiple rounds of route queries and transfer plan confirmations. Timeout setting must cover the full inquiry process to avoid mid-process interruptions |
Three common mistakes
- Phenomenon: User sends a new message before completing the form, causing the process to interrupt and the form to be unresponsive. Cause: No timeout interruption and new message interception rules configured for
formInput. The system waits by default for form submission, and does not recognize subsequent new messages as new inquiry requests. - Phenomenon: The form's drop-down menu displays discontinued bus routes, and the options do not match official data. Cause: Static option update frequency does not match official data change cadence, and no daily automatic sync rule is set, causing the option library to lag behind official data.
- Phenomenon: The system cannot recognize the arrival delay value entered by the user, and returns a format error after submission. Cause: No form input validation rules configured, and no input format and unit restrictions set, so the system cannot match the minute-level precision requirements of business data.
How to confirm the configuration is complete
- Open the form configuration page, check if
formInputincludes high-frequency public transit inquiry preset options and free input box, confirm that the options cover common inquiry scenarios. - Trigger the
userSelectdrop-down menu, check if the loading delay meets the preset sync frequency requirements, confirm that the displayed routes match the latest official data. - Test input values in different formats, confirm that the system only accepts compliant formats and automatically completes the unit identifier.
- Trigger the static option batch update task, confirm that the updated option library is synchronized with official operation log data.
