The Game at a Glance
What is Trafficity?
Trafficity is a traffic-focused city builder developed and published by Onramp Games. Rather than managing civic budgets and municipal services, players design complex road networks and resolve vehicular congestion through an agent-based microscopic traffic simulation on Windows and Mac platforms.
During gameplay, you expand your metropolis by placing gridless roads, custom intersections, and zoned districts. As your settlement levels up, smart agents commute between residential homes, office workplaces, factories, and commercial shops, requiring multi-tier highway interchanges and signal timing to avoid citywide gridlock.

Beginner Guide
Build road grids at any angle and connect residents with shops and workplaces. Add lanes, roundabouts and overpasses as your city expands.
Create road grids at arbitrary angles using three clicks or place freeform streets across terrain.
Place residential, commercial, industrial, and office zones to establish commuter routes and delivery supply chains.
Connect specific lanes, construct roundabouts, or program phased traffic signals to keep traffic moving.
More details
Earn new building batches through city level progression while separating noisy industrial corridors from housing.
Traffic Lights and Junctions
Customize signal phases, protected left turns and lane connections to address traffic hotspots. Cars choose routes based on congestion, making road hierarchy and interchange design essential.
Native lane routing tools let you connect individual approach lanes directly to designated target lanes across junctions.
Customizable timing menus allow you to configure green light durations and set protected turn phases.
Directly placed or curved roundabouts route circulating traffic around a central ring with yield behaviors.
More details
Stack highway bridges up to four layers high to assemble complex interchanges like cloverleafs and directional stacks.
Buildings and City Growth
Factories require workers and raw materials, while shops need customers and goods. City level-ups provide new buildings, and residents dislike industrial pollution and road noise.
Green residential zones house citizens and produce commuters while suffering penalties from road noise and pollution.
Blue commercial shop zones attract customer vehicle traffic and demand freight deliveries of finished goods.
Orange factories process raw materials into goods for distribution depots while employing local workers.
More details
Advancing your city level rewards batches of new structures to expand your metropolitan footprint.
Maps and Difficulty
Explore procedurally generated maps across four biomes with distinct playstyles. Three difficulty levels offer different challenges for your growing road network.
Four distinct biome presets present unique terrain challenges and construction constraints.
Three available difficulty levels tune the intensity of traffic generation and economic thresholds.
An optional in-game checkbox darkens the interface and terrain elements for low-light gameplay.
