MEANINGS
Three ways people use the words incremental traffic
This site is about the game. The same words also name a way to assign trips in transport planning, and a way ad teams talk about new users. I keep the three apart instead of forcing one definition.

The game
On Steam, Incremental Traffic is a logistics game by Rischer Kriebl. The store line is “An incremental logistics game where traffic becomes a challenge.” It is Windows only, on sale from a store date of 1 Nov 2026, with 96 achievements. Trucks move shapes between presses, and the tools are yield signs, stops, lights, lanes and roundabouts. That is the long section, because it is the subject of the rest of this site.
The transport-planning method
In route assignment, incremental assignment splits the trip table into a few portions, often four. You assign the first portion, recompute travel times, assign the next portion, and repeat until the whole table is placed. The phrase on the reference page is incremental traffic assignment, not the game's title. If your assignment is a homework sheet about that method, the game's trucks will not answer it.
The advertising phrase
Ad teams use incremental traffic for users who were not already in a channel they buy. One UA article tells teams to look for sources with incremental traffic, and describes fresh users who are new to gaming and do not come from inventories the team already buys. That sentence is about acquisition, not about a roundabout.

Questions
Which meaning ranks for the short query?
Around launch week the game took the name on Steam. Homework and ad posts still use the longer phrases. I do not have a click split.
Is there a dictionary entry for the exact phrase?
I did not find a standalone dictionary entry. The engineering page defines incremental assignment. The ad page defines incrementality in user acquisition.
Where should I go for the game?
The home page and the achievement table. This page does not grow a transport-planning tutorial.
