Assess traffic delays using route records

Track actual stop time, load and plate conditions together; validate any delay allowance with product records.

Short answer

During a delay, record stop start and end, container ID, load and driver actions. If product instructions require it, monitor temperature at a suitable location on the same load and document plate preparation status. Validate the route allowance with repeated actual trips; do not infer safe extra time from catalogue duration or whether the engine is running.

Time in traffic changes the route plan; its effect on product depends on load, packaging, cold source and ambient conditions. Do not declare a delay safe by guesswork.

Create an event record

Log vehicle and container IDs, stop location, delay start and end, door openings and actions taken.

Monitor the product

If product instructions require it, measure with the approved device and location. Link sensor, product, container and route details in one record.

Verify the cold source. Compare plate type, article and preparation record with maker instructions. Do not use a nominal duration as an actual route allowance.

Set route slack from actual data

Compare delays and handover measurements across trips with similar loads and delivery arrangements. Separate changed conditions and give the route owner an updated deviation plan.
