Incremental Traffic

Incremental Traffic is a transport and logistics game about delivering goods through a growing town. You route your trucks through fixed streets, adjust the traffic rules and manage congestion as your deliveries expand the city and increase demand.

Shape the traffic

You cannot change the streets themselves, but you can set who yields, where vehicles stop, when traffic lights turn green, how many lanes a street has and where roundabouts go. The lane-based simulation can produce traffic jams, gridlock and deadlocks. Every vehicle is one of your trucks on a route you chose; there are no commuters, rush hour or random cars, so you can trace a jam to its cause and change your plan.

Deliver goods

Production chains are short: factories press and assemble shapes into new shapes. The main challenge is transporting goods, since a factory with eight loading bays cannot help if the street outside is jammed. There are five tiers of goods, from simple shapes to large products that take up two slots and combine multiple simpler shapes.

You can choose from four truck models, ranging from the cheap Hauler to the on-time Express. Factory upgrades speed up production, creating demand for more trucks and busier streets. As you fix congestion, earn more and upgrade again, each new jam becomes larger.

Grow the town

Each valley town is generated around its own economy. Its busiest roads carry your freight, routes share streets and cross one another, and bypasses are placed where you are likely to need them. You start in a small town that grows as you transport more goods; demand spreads one district at a time, and the city develops into apartment blocks and highrises around your trucks.

Later, you can buy whole new bridges, bypasses and shortcuts, then reroute large parts of the town. Valley towns span 3 to 8 regions, and the game also includes endless Boomtown.

All tools from the start

There is no meta-progression or need to unlock tools across runs: all the tools are available from the beginning.
