Over an API, operated by SmartWay
The route optimisation core your TMS needs
Route4Green takes the list of orders and the list of vehicles for a date, works out how many vehicles you need and which orders each one carries, and only then sequences the stops on each route. Every run covers the whole fleet, up to 300 orders, for one date and one transport mode. The result is fewer trips and fewer kilometres per tonne of cargo.
What route optimisation is, and why optimising one vehicle at a time is not enoughSmartWay TMS runs on this same engine. If you operate a fleet, you can start with a free one-day measurement on your own data, against your own plan.
Who Route4Green is for
The route optimisation core is the engine that runs behind your software, connected over an API. TMS vendors build it into their product; fleet operators try it first on their own real data.
TMS and transport software vendors
Add route optimisation to your TMS
Your customers assign orders across their whole fleet inside the TMS they already use. You only call the API: SmartWay operates and hosts the engine, and the product and the customer stay yours.

Try it free on one day of your data
Send one day or one shift of data: orders, the vehicle list, constraints and the plan you ran. We send back the routes Route4Green computes, set against that plan so you can compare them, free. If it fits, keep using it through SmartWay TMS or have your engineers connect over the API.
Request a one-day measurementHow much you gain depends on how often you plan each month and how many vehicles you schedule at once. From a few dozen vehicles up, assigning orders and building routes by hand usually becomes too much.
Enterprises running a large fleet of their own
Postal, distribution and manufacturing companies with their own fleet of a few dozen vehicles or more, serving many stops a day. Every percent of trips and kilometres you cut adds up over every operating day.
Logistics operators and 3PLs
Middle-mile and last-mile transport, five or more stops per trip. When shippers ask for figures per shipment, every planning run already gives you trips, kilometres and cargo for each route.
Who has worked with Route4Green
One Pilot, with measured figures
A Pilot with Vietnam Post (VNPost) in Ho Chi Minh City, July 2026. Route4Green planned in parallel with VNPost's fixed routes, on the same order data.
What the API does
Public documentation, readable before you sign anything.
Fleet-wide assignment and route optimisation
Send your whole order book and fleet in one job, up to 300 orders for one date and one transport mode. The core decides which vehicles to use and which orders each carries, then sequences the stops, and returns what it could not place. Jobs run asynchronously.
Orders and request pools
Push orders in, pool them, and the core decides which orders share a run.
Vehicles and vehicle plans
Declare payload, box dimensions, working windows and a separate start point for each vehicle.
Webhooks
Get notified when a job finishes, instead of polling.
API keys
Issue and revoke keys per integration, yourself.
Applications around the core
The core and the API are the product. SmartWay builds these applications on the same core; custom ones are quoted separately.

Why the hard part is not the algorithm
Route optimisation algorithms are available as open source, and we are not going to pretend otherwise. The expensive part sits elsewhere: describing your operation accurately enough that a solver can honour it, decomposing the problem at your fleet size, and keeping the result usable while your drop-point data is still imperfect. Route4Green ships that work as an API. If your engineering team wants to build it in-house, we will tell you plainly which parts are worth building and which are not.
Mathematics, not AI. The core solves order assignment and routing with operations-research optimisation methods; it does not learn from your data.
