When a multi-site program falls behind, the usual response is to push contractors to work faster on site. More jobs per day, shorter visits, longer shifts.
But in multi-site field work, the biggest loss usually isn't on site. It's on the road. A contractor who drives past three open tickets to reach a fourth is losing time no amount of on-site speed can win back.
Route optimization fixes this at the planning stage. Instead of assigning tickets as a list, managers assign them as a map: group nearby sites, send them to one contractor, and let the system build the fastest order of stops. With fuel, labor and deadlines all under pressure, this is one of the quickest wins available to operations teams.
Route Optimization Cuts 15–30% of Drive Time Because Most Routes Are Built by Hand
Most contractor routes are still built by a dispatcher, a contractor's own instinct, or the order tickets happened to arrive. None of these reliably find the shortest path across a full day of stops.
Published field service case studies and operator interviews put the typical drive-time reduction at 15% to 30% when teams switch from hand-built routes to automated route optimization. Fleet data from Geotab, cited by Maptive, shows a similar 15–30% drop in mileage.
Every minute saved on the road is a minute available on site. Over a full program, that time turns into more completed sites per contractor, without anyone working harder.
Contractor Route Planning Works Best on a Map, Not a Spreadsheet
A list of addresses hides the geography. Two sites can sit far apart in a spreadsheet but only minutes apart on the road.
Map-based contractor route planning shows every open ticket as a point. A manager can see clusters at a glance, select all the tickets in one area, and assign them to the contractor closest to that cluster. In ClickPM, this happens in a few clicks: select tickets on the live map, pick the contractor, and the route is generated automatically.
This also stops a common waste: two contractors from different companies driving to neighboring sites on the same day. On a map, that overlap is obvious. In a list, it's invisible.
Field Service Routing Only Pays Off When Contractors Can See the Route
An optimized route that lives only in the manager's screen still ends up as a phone call, with the manager reading out stops one by one.
Field service routing works when the route goes straight to the contractor. Each contractor should open their own view, see their tickets in order on a map, and get turn-by-turn navigation from there. ClickPM's Contractor Portal does this, so the plan and the field stay in sync.
It also makes changes cheap. When a site gets cancelled or an urgent ticket comes in, the manager re-assigns it on the map and the contractor's route updates. No new email chain needed.
Evidence in Practice
Published results from teams that moved from manual to automated routing:
Drive time: Analyses of field service case studies put the typical drop at 15% to 30% when teams switch from dispatcher-built routes to automated route optimization.
Mileage: Geotab fleet data, cited by Maptive, shows a 15–30% reduction in miles driven.
Fuel: A Fieldproxy route optimization guide estimates that a 25% cut in drive time usually lowers fuel costs by 20–30%.
Single-company result: A published HVAC case study reported a 30% cut in average daily drive time per technician and a 28% drop in monthly fuel costs, while service volume went up.
Most of these figures come from routing vendors, so treat them as a guide and measure the results on your own sites.
What This Means for Dispatchers and Project Managers
Stop assigning from a list. Put open tickets on a map before you assign anything.
Cluster first, then assign. Give each contractor a tight geographic group, not a random mix of addresses.
Send the route, not just the tickets. Contractors should open their day already in order.
Track sites per day, not hours worked. It's the clearest measure of whether routing is working. See 7 KPIs every multi-site project manager should track.

Frequently Asked Questions
What is route optimization in field service?
Route optimization is finding the most efficient order of stops for a contractor or technician, based on location, so they spend less time driving and more time on site.
How much time can route optimization save?
Published case studies usually report a 15–30% cut in drive time when teams move from manual planning to automated route optimization. Results depend on how spread out your sites are.
