This prototype simulates two intersecting lines with a single critical shared segment and enforces one-train-per-junction using a priority-aware greedy scheduler. You can add trains, toggle priority handling and rescheduling, trigger emergencies that block the central edge, and observe throughput and delay metrics over time with a chart and event log. To install or deploy, open the preview’s menu to Download ZIP or Publish to Vercel; the shadcn setup is already present in this environment.

I updated the effect dependencies to include graph, config, and edgeBlock so the interval uses current values, and moved the metrics timing check into the functional setMetrics callback to avoid capturing metrics in the closure. This resolves the exhaustive-deps lint warning and ensures the simulation reacts immediately to config toggles and emergency blocks.

Prototype Prompt“Design a smart railway traffic control system dashboard. The interface should show real-time train movement, track status, signals, delays, and rescheduling suggestions. Include a map view with moving train icons, highlighted junctions, and dynamic alerts. Add panels for delay predictions, conflict detection, and emergency handling. The system should also have a timetable optimization panel and a command center where operators can control signals and routing. Use a modern, minimal, and intuitive style with blue, grey, and green tones. Provide a mobile app version for passengers showing real-time train arrivals, delays, and notifications.”✨ With this, you’ll get:Admin Dashboard UI → for railway operatorsPassenger App UI → for real-time travel updatesVisualization Components → maps, graphs, alerts, scheduling panelsWould you like me to refine this prompt separately for two use cases:Operator Dashboard PrototypePassenger Mobile App Prototype

Here are two refined prompts you can use directly.

Operator Dashboard Prototype — Prompt

Goal: Smart railway control-room dashboard for dispatchers to monitor and manage live train traffic.
Visual style: Modern, minimal, high-contrast. Colors: primary blue, neutrals (white/gray/near-black), green as “normal/clear,” red/orange exclusively for alerts. Max 5 colors total. No gradients.
Layout: Desktop-first 1440px container; responsive down to 1024px. Flex-based layout. Left: Network Map. Right: stacked panels. Global top bar with date/time, system health, search.
Components:
- Live Network Map: moving train icons, highlighted junctions, track segments with signal states (red/yellow/green), block occupancy, speed limits, and disruptions. Zoom/pan, hover tooltips, keyboard navigation.
- Conflict Detection: list of upcoming conflicts (train-train, train-work block), ETA to conflict, severity, resolution suggestions.
- Delay Predictions: per-train predicted delay minutes with confidence; color-coded badges; sparkline trend.
- Rescheduling Suggestions: ranked options with impact on network KPIs (throughput, delay-minutes); Apply/Dismiss actions with confirmation.
- Emergency Handling: declare block/clear segments, set speed restrictions, evacuate stations, broadcast alerts; action log with user/time.
- Timetable Optimization: import current schedule, run optimization, preview diffs (before/after), constraints toggles (maintenance windows, priority trains).
- Command Center: direct signal/routing overrides, route reservation requests, queue viewer.
- KPIs & Charts: throughput, on-time %, average delay, blocked segments, incidents; Recharts with accessible tooltips.
- Event Log: filterable by severity/type; export CSV.
Interactions:
- Real-time updates (simulated if no backend). No fetch in useEffect; use RSC or SWR for polling. Keyboard shortcuts for map (arrows, +/-), actions (E for emergency panel, O for optimizer).
- Role-aware confirmations for risky actions; undo where possible.
Accessibility: semantic regions, aria-live for alerts, focus management for dialogs, high-contrast adherence.
Deliverables:
- Next.js App Router page with the layout described.
- Map component with simulated trains and junctions.
- Conflict and Delay panels fed by a simple scheduler/predictor mock.
- Emergency and Command Center panels with optimistic UI and audit log.
- KPI cards and charts using Recharts.
Acceptance criteria:
- Single-train-per-block rule enforced in the sim; conflicts appear when violated.
- Emergency “block segment” immediately reroutes or stops trains; state visible on map and panels.
- Optimization preview shows before/after times and projected KPI change.
- All alerts use red/orange; normal states use blue/green; total colors ≤5.

Passenger Mobile App Prototype — Prompt

Goal: Mobile-first app for riders to see real-time arrivals, platform info, delays, and receive notifications.
Visual style: Friendly, simple. Colors: primary blue, neutrals gray/white, accent green (on-time), amber (minor delay), red (major disruption). ≤5 colors. Large tap targets.
Layout: iOS/Android-friendly bottom tabs: Home, Plan, Alerts, Account.
Screens:
- Home: nearest stations (GPS or input), upcoming arrivals with countdown, platform numbers, crowding level; pull-to-refresh.
- Line Status: per-line good service/minor delay/major disruption with color-coded badges.
- Trip Planner: origin/destination, departure/arrival time, suggested routes with transfers, ETA, fare estimate; “Notify me” toggle.
- Alerts & Notifications: service alerts feed, subscribe/unsubscribe per line/station; quiet hours.
- Station Detail: map snippet, platforms, accessibility notes (elevators), facilities.
Interactions:
- Offline-first: cache last known schedule and station list; show “data stale” badge.
- Notification preferences stored locally; simulate push via in-app toasts.
Accessibility: dynamic type, VoiceOver/ TalkBack labels, color contrast, haptics for critical alerts.
Deliverables:
- React components for the screens above with mocked data providers.
- Reusable ArrivalCard, StatusBadge, AlertItem, RouteOption components.
- Simple settings store for notification and accessibility preferences.
Acceptance criteria:
- Arrival times update every 15s (simulated) and reflect delays.
- Alerts badge shows unread count; tapping marks read.
- Planner shows at least two route options with transfer steps and color-coherent line badges.

Would you like me to start building the Operator Dashboard first, the Passenger App first, or create both in the repo as separate routes (e.g., /operator and /passenger)?
