Dynamic routing
What is dynamic routing?
Dynamic routing, also called adaptive routing, is the process of recalculating delivery routes to adapt to changing conditions. It considers factors such as traffic patterns and customer unavailability, continuously rerouting drivers to achieve optimal resource utilization.
Unlike static routing, dynamic routing adjusts sequences and assignments once drivers are already in progress. This is why it's often used to meet customer requirements for things like rush requests or same-day order additions.
Dynamic routing vs static routing
Route planning in logistics falls into two broad categories—static and dynamic.
Static routing: routes are configured in advance and updated manually by a planner or administrator. Deliveries follow those fixed paths with no deviation, so if a predefined route becomes unavailable, the delivery stalls
Dynamic routing: routes are recalculated automatically as conditions change, using live network and traffic data to reassign stops and resequence stops mid-route
The practical difference is adaptability. A static plan can't respond to a closed road, a late order or a driver running behind, and it gives dispatch no structured way to push changes out to drivers. Dynamic routing scales as delivery volumes and network complexity grow, absorbing new stops and disruptions without a replan from scratch.
How dynamic route planning works
The transportation management system (TMS) is fed real-time data including:
GPS driver locations
Traffic speeds from mapping services
New customer orders from e-commerce systems
Delivery status updates from driver mobile devices
The TMS continuously processes these inputs, identifying when current routes become suboptimal. It calculates whether rerouting would be more efficient and, if so, which route best balances competing objectives. To do this, it evaluates:
Total distance
Delivery time windows
Vehicle capacity
Driver hours-of-service limits
Customer priorities
After route optimization is complete, new directions are sent to the driver’s mobile device. Over time, the TMS refines its optimization algorithms based on how well its routing decisions performed in the real world.
Benefits of dynamic routing
Dynamic routing changes what a delivery operation can commit to. The main gains:
Improved route efficiency: live GPS tracking and driver communication let dispatch review on-road performance as it happens and send instant updates to the driver mid-route
More stops per hour: stops per hour is one of the clearest measures of delivery productivity, and resequencing routes against live conditions raises it
Better exception handing: reporting and dashboards give operations managers, fleet managers and drivers a shared view of on-road performance, so problems surface while there is still time to act
How a TMS handles dynamic routing
In a TMS, dynamic routing runs as an assignment engine rather than a planning step. Delivery and pickup stops are routed to the driver best positioned to take them, weighed against time allocated for deliveries versus pickups, miles driven, assets used, service times, weight, cube and skid equivalent. The system produces a route plan dispatch can accept as-is or override using criteria the algorithm doesn't hold.
Capabilities that typically sit inside that engine:
Scheduled pickup routing: a pickup is assigned to a set route or a preferred driver and stays there until dispatch changes it
Best and next-best assignment: the system recommends the optimal driver for a stop, and dispatch can accept it, request the next best option or choose manually
On-demand pickup routing: as pickup requests arrive through order entry or an integration, they are assigned automatically based on miles, weight already loaded, remaining trailer space and stops already assigned, with no dispatcher involvement unless the assignment is overridden
Dynamic driver adjustment: routes re-optimize around driver events such as out-of-order stops, a closed customer site, a reschedule, a breakdown or a trailer swap
