Somebody has to model the freight
Each item, its weight, its dimensions and where it sits on the deck, plus the tractor and trailer geometry underneath it. That model is what turns a pile of pallets into five axle numbers.
Head to head
HERE takes vehicle height, width, length, gross weight and weight per axle, and returns a road that respects all of them. Every one of those figures is something you have to already know.
Who it is for
This is road infrastructure of a very high standard, and it is deliberately built to be built on.
HERE publishes truck routing that takes the real dimensions of a commercial vehicle and plans around the structures, streets and restrictions those dimensions rule out. Hazardous material restrictions are applied, toll costs come back with the road, and the coverage runs across continents rather than one market.
Underneath the routing sits the rest of the platform — maps, geocoding, place data and traffic — which matters more than it sounds. A freight application needs an address to resolve correctly before anything else it does can be right, and address quality is not a solved problem for anyone who has not spent decades on it.
Notably, the routing accepts a weight per axle. That is an unusually honest parameter to expose. It says, correctly, that the structure ratings on a road care about what each axle is putting down, not about a gross figure. It also quietly assumes the caller has that number.
The parameter is the right question. Somewhere upstream of it, a person is dividing a gross weight by the number of axles.
The parameter that gives the game away
The job it was not built for
Three things have to happen before that parameter can be filled in honestly, and none of them belongs in a road network.
Each item, its weight, its dimensions and where it sits on the deck, plus the tractor and trailer geometry underneath it. That model is what turns a pile of pallets into five axle numbers.
The bridge formula across every consecutive axle group, the tandem exception where it applies, the tire ratings and the axle ratings, in the jurisdiction the truck is actually in.
A verdict with no instruction sends the load back to the dock with a shrug. The output a yard can use is a distance and a direction.
A worked example. Three figures solved from where the freight actually sits, on a 77,720 lb combination. Divide that gross by the axle groups instead and every one of the three numbers is wrong, in both directions.
A road network is asking, correctly, what each axle puts down. It takes whatever it is handed on trust. Hand it a figure that came out of a bill of lading and the road you get back was planned for a truck that does not exist.
Side by side
Maps, geocoding, tolls and global coverage are the other column's, and there is no version of this where we take them over.

Methodology
When to pick them instead
You are building routing into your own software and need commercial vehicle road data as infrastructure. That is precisely what HERE is for.
You need coverage well outside North America. Our jurisdiction rule sets are configured per deployment; a global road network is not something we hold.
You need maps, geocoding, place data and routing from one supplier under one commercial agreement.
You need toll cost returned with the route as part of a quoting flow.
Working together
Freight positions and equipment geometry go in. What each axle group actually carries comes out, with the binding rule named for the jurisdiction on the route.
A commercial vehicle routing service asks for weight per axle. Now it is being given a figure derived from the load rather than a gross weight divided by a hope.
Each leg is re-solved against the freight still aboard, because a run legal at leg one can be illegal at leg three.
Maps, geocoding, places, tolls and global coverage are HERE's business and there is no reason for that to change.
