Route Optimisation: How to Save Time and Fuel

Smart route planning is one of the fastest ways to lift fleet productivity. You do not need new vehicles, new drivers, or new technology — you just need to use the routing tools you already have, properly.

What route optimisation actually means

Route optimisation goes beyond finding the shortest path. A truly optimised route accounts for:

  • Real-time traffic patterns (think Morogoro Road at 17:00)
  • Customer time windows
  • Vehicle capacity and load constraints
  • Driver schedules and rest requirements
  • Customer preferences (delivery hours, access)
  • Road restrictions, weight limits, and seasonal closures

The benefits, in numbers

Time savings

  • Typically 15–25% reduction in driving time
  • More stops completed per day
  • Better on-time performance

Fuel savings

  • 10–20% reduction in fuel cost on optimised routes
  • Fewer kilometres driven overall
  • Less idling in traffic

Customer satisfaction

  • Tighter ETAs
  • More consistent service windows
  • Fewer missed appointments

Five strategies that work

  1. Cluster stops geographically — group nearby drops together so a driver does not zig-zag across town.
  2. Respect traffic patterns — schedule the port and city-centre runs outside peak congestion windows.
  3. Prioritise by time window — time-sensitive stops first, flexible stops last.
  4. Balance workloads across drivers — avoid the situation where one driver does ten stops and another does three.
  5. Account for loading time — if a typical pickup takes 20 minutes, plan for 20 minutes, not 5.

Using GPS data for planning

Historical GPS data is the secret weapon most fleets ignore. With it you can:

  • Identify recurring bottlenecks (e.g. specific intersections that cost 15 minutes every morning)
  • Compare planned vs. actual times per stop
  • Find routes drivers prefer for good reasons — and copy them
  • Spot underutilised side roads

KPIs to measure success

  • Kilometres driven per stop
  • Fuel cost per delivery
  • On-time delivery rate
  • Driver overtime hours
  • Customer complaints per 100 deliveries

Route optimisation is not a one-time project. Re-plan monthly as new customers, new traffic patterns, and new road works appear.
