Flexible Route Planning
Flexible route planning is the ability to adjust planned routes as operating conditions change. It allows dispatch teams to respond to traffic, urgent customer requests, cancelled stops, vehicle faults, driver availability, delivery delays, and changes in pickup or delivery priority.
A route may be re-optimised using current vehicle locations, remaining stops, appointment windows, capacity, driver hours, road restrictions, service times, and customer requirements. The system recalculates a practical sequence and may reassign work between vehicles when necessary. However, the mathematically shortest route is not always operationally suitable if it ignores access restrictions, cargo compatibility, service commitments, or driver familiarity.
Not every disruption requires a complete route change. Frequent adjustments can confuse drivers, create inconsistent arrival estimates, and introduce new delays. Dispatchers should assess the impact of a change before approving it and communicate updated stops, instructions, and arrival times clearly. Significant changes may also require customer notification. Fleets can evaluate flexible planning by comparing on-time performance, miles travelled, missed stops, overtime, fuel use, and customer complaints before and after re-optimisation. When applied selectively, it protects service levels, uses available capacity more effectively, and helps operations recover from disruptions without rebuilding every route manually.
Common questions
Quick answers related to Flexible Route Planning.
What events can trigger route re-optimisation?
Route re-optimisation may be triggered by congestion, road closures, vehicle breakdowns, late departures, failed deliveries, urgent collections, cancelled orders, changing customer time windows, driver-hours limits, or unexpected capacity constraints. Trigger rules should reflect the operation’s service priorities and practical restrictions.
How does flexible route planning differ from static planning?
Static planning creates routes using information available before vehicles depart and generally keeps them unchanged. Flexible planning uses updated operational data to revise stop sequences, arrival estimates, or vehicle assignments when changing conditions make the original plan less effective.
Should every traffic delay cause a route change?
No. Minor or temporary congestion may clear before an alternative route provides any benefit. Fleets should consider delay severity, confidence in traffic data, remaining stops, road suitability, customer commitments, and the disruption caused by sending new instructions to drivers.
Can customer requests be added after a route has started?
Yes, when vehicle capacity, driver hours, cargo requirements, access conditions, and existing commitments allow it. The system can evaluate suitable vehicles and insertion points, but dispatchers should confirm that accepting the request will not create unacceptable delays for other customers.
How can fleets measure the value of flexible route planning?
Fleets can monitor on-time arrivals, completed stops, unplanned mileage, fuel consumption, overtime, missed appointments, response time, and customer complaints. Results should be compared with similar routes and demand conditions to determine whether re-optimisation improved overall performance.
