What data for this category looks like
Data for this category originates from highway operation work order management systems, offline inquiry ledgers, and real-time road network dispatch platforms. Two update schedules apply: real-time inquiry data updates immediately when a user submits it, while work order data updates when its completion status changes. The standard document structure includes fields for inquiry type, associated road section or site, inquiry initiation time, request details, processing node, and completion result. Field units include kilometers, hours, entries, and similar units, with no complex nested hierarchies.
What constraints these characteristics impose on form and interaction
Fixed fields for associated road sections and sites require forms to preset standardized dropdown options to prevent incorrectly formatted location information from being entered. Real-time updated inquiry data requires interaction flows to support immediate submission and status synchronization to avoid data delays. Multi-node processing workflows require forms to be split into step-by-step filling sections, with inquiry type, location, and request details split into separate interaction modules to lower user entry barriers. Some inquiries involve static content such as toll standards and traffic restriction rules, so quick jump links must be embedded in the interaction to reduce repeated query effort for users.
How to set configurations
Reference only; verify against the target FastGPT release and deployment documentation.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
formInput | Maximum 800–1200 characters per field | Matches the typical length of highway inquiry requests to avoid truncating valid information |
userSelect | Preset 10–15 categorized options | Covers high-frequency inquiry types including tolls, traffic passage, rescue, facility maintenance requests, and similar categories to reduce input costs |
| Single submission timeout | 30 seconds | Adapts to highway users' waiting patience to avoid information loss from timeout interruptions |
| Context window | First 3 rounds of conversation history | Retains inquiry context without requiring repeated input of basic information |
| Linked field trigger | Triggered by inquiry type | Only loads associated fields corresponding to the selected category to simplify page complexity |
Three common configuration errors
- Issue: Content is truncated after submitting the
formInputfield, with only the first 600 characters retained. Cause: The maximum character length for theformInputfield was not adjusted, and the default value is shorter than the length of the user's submitted request. - Issue: Voice input submission prompts "unable to parse audio", and error code 400 is displayed on the interface. Cause: The deployment environment was not properly configured with audio and video processing dependencies, and root permission is not available to install ffmpeg-related components.
- Issue: Associated fields do not load automatically after the user selects an inquiry category. Cause: Linked rules for
userSelectwere not configured, and no mapping relationship was established between the category options and subsequent fields.
How to verify successful configuration
- Submit a simulated highway inquiry request to confirm that the input content is fully retained without truncation.
- Select different inquiry categories to confirm that the corresponding associated fields load correctly.
- Test the voice input function to confirm that audio can be normally converted to text content.
- After submission, check the context window to confirm that the first 3 rounds of conversation history are correctly retained.
