Build a Public Weather Assisted Port Delivery Route Planner

Correlate Singapore open real-time weather readings with heavy vehicle delivery schedules across port corridors. Reschedule hauler dispatches around high-intensity rain events to prevent terminal roadway gridlock.

Container drayage dispatch controller

Fetch real-time station rainfall data from the Singapore Open Data API.

Ingest scheduled container pickup itineraries between Jurong industrial hubs and PSA terminals.

Identify high-precipitation corridors exceeding heavy vehicle safety thresholds.

Reorder hauler dispatch sequences and output revised driver slot assignments.

Map-based corridor dashboard displaying real-time rainfall overlays, truck queue estimates, and a schedule rebalancing queue.

Query public real-time rainfall endpoints on data.gov.sg or mock the endpoint using recorded monsoon season precipitation matrices. Starter examples below are synthetic. They are not downloaded records.

Singapore open data API Consumes the data.gov.sg real-time weather API structure to query rainfall observations across Singapore monitoring stations.

langgraph, httpx, fastapi. LangGraph manages stateful routing decisions and loop-back verification when rescheduling drayage runs. Efficient local or API LLM capable of evaluating route constraint graphs and generating driver itineraries.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Queries data.gov.sg real-time rainfall data format and identifies stations with heavy rain (>20mm/h).

Delays dispatch times for trucks traversing high-rainfall sectors by at least 45 minutes.

Exports a rebalanced schedule preserving total daily terminal appointment quotas.

Does not control prime mover navigation hardware; provides advisory schedule recommendations to human controllers. Use mock external writes. Require human review before any real deployment.
