Build a Port Congestion Aware Green Drayage Route Planner

Correlate Singapore real-time traffic camera and road incident data with electric and diesel heavy prime mover fleets. Optimize container hauling routes to minimize carbon emissions during port corridor congestion.

Green logistics fleet coordinator

Ingest Singapore Expressway camera images and real-time congestion incidents via open data APIs.

Extract speed bottlenecks on primary freight arteries including AYE and West Coast Highway.

Calculate vehicle emissions differentials between electric haulers and diesel trucks idling in queues.

Synthesize dynamic route adjustments and output emission reduction audit logs for corporate ESG reports.

Live fleet dispatch console displaying arterial speed estimates, hauler powertrain types, and rerouting prompts.

Use mock traffic incident payloads conforming to data.gov.sg real-time traffic condition datasets. Starter examples below are synthetic. They are not downloaded records.

Singapore open data API Leverages the data.gov.sg real-time API specifications for traffic conditions and speed bands along Singapore port expressways.

dspy, httpx, pydantic. DSPy compiles robust prompt pipelines that optimize emission factor evaluations and route trade-off reasoning. Instruction-tuned model evaluated with DSPy teleprompters for zero-shot route selection accuracy.

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.

Processes real-time expressway congestion metrics structured according to data.gov.sg schemas.

Reroutes diesel vehicles when bottleneck delay exceeds 30 minutes to reduce idling carbon footprint.

Outputs an ESG-compliant trip record quantifying estimated CO2 savings in kilograms.

Outputs routing recommendations strictly as suggestions for fleet dispatchers; vehicle steering is not automated. Use mock external writes. Require human review before any real deployment.
