Trafficity is an upcoming traffic management city builder developed and published by Onramp Games, scheduled for release on November 16, 2026, for PC and Mac. Unlike traditional city builders that focus heavily on civic budget balancing and municipal service coverage, Trafficity centers its gameplay on designing efficient road networks, managing intersections, and solving congestion through an agent-based microscopic traffic simulation.
This guide outlines all confirmed gameplay systems, road construction tools, traffic signal configurations, zoning mechanics, and technical details revealed across official developer updates and gameplay showcases.
Core Road Construction and Interchange Tools
Trafficity uses a flexible, gridless road layout engine that allows you to construct streets and highways without being locked to rigid 90-degree angles. Road networks can be shaped freely across flat terrain, over water, and through varied elevation contours.
- Three-Click Road Grids: You can generate road grids at arbitrary angles using three clicks to designate the first corner, opposite corner, and road width.
- Direct Lane Expansion: Rather than forcing a full road upgrade to wider street profiles, the interface lets you draw individual lanes directly alongside existing roadways to form turning bays, slip lanes, or rest stops.
- Acceleration and Slip Lanes: Gameplay trailers demonstrate that side lanes merge smoothly into through-traffic, allowing vehicles to merge or bypass major intersections without halting main artery flow.
- Multi-Tier Elevation: Road networks support vertical layering. Gameplay analyses reveal bridge stacks up to four layers high, complete with drop shadows and elevation markers (such as elevation levels 1 through 4) to navigate complex multi-level highway interchanges like trumpets, cloverleafs, and full directional stacks.
- Driving Direction Toggle: The game supports both right-hand traffic (RHT) and left-hand traffic (LHT), confirmed across multiple gameplay showcases.
Traffic Management and Junction Controls
To prevent citywide gridlock, Trafficity includes built-in intersection control tools that eliminate the need for third-party traffic mods.
Native Lane Connectors
At any intersection, players can manually designate lane routing. You can select individual lanes entering an intersection and map them directly to specific target lanes across the junction—such as dedicating two lanes for through-traffic and one lane for dedicated turns.
Configurable Traffic Light Phasing
Intersections with traffic lights feature an in-depth timing and phase customization menu. Key features include:
- Phase Duration Controls: Adjust how long each green and red interval runs across each approach.
- Protected Turns: Set distinct phases for protected left turns (or right turns in left-hand drive configurations) to prevent oncoming collisions.
- Visual Phase Toggles: Clickable green/red phase indicators allow players to isolate conflicting vehicle flows easily.
Roundabouts
Roundabouts can be placed directly or built out using curved road segments. The microscopic simulation routes traffic around the central ring while vehicles yield before entering, providing an alternative to signaled intersections for medium-density junctions.
City Economy, Zoning, and Traffic Generation
Trafficity features a lightweight urban economy designed specifically to create realistic trip generation and freight logistics. Vehicles do not move randomly; smart agents travel between home, work, and commercial destinations.
| Zone / Building Type | Map Color | Role and Traffic Behavior |
|---|---|---|
| Residential | Green | Houses low-to-medium density populations; generates commuter trips and shopping runs; sensitive to noise and industrial pollution. |
| Commercial / Shops | Blue | Requires freight deliveries of goods to sell; generates high-volume customer vehicle traffic. |
| Industrial / Factories | Orange | Emits noise and pollution; requires raw materials to produce goods; employs residential workers. |
| Offices | Purple | Generates commuter trips for office workers without industrial freight output. |
| Raw Material Sites | Map-specific (e.g., Mines) | Located at terrain features like mountains; dispatches heavy trucks carrying materials. |
| Depots | Dedicated Structures | Serves as distribution hubs where industrial cargo trucks transfer goods bound for commercial zones. |
City Leveling and Progression
Progression operates on a city level-up model. Each time your settlement levels up, you receive a batch of buildings to place. Because residential zones penalize road noise and pollution, you must separate heavy industrial corridors and raw material truck routes from residential housing estates, using sound buffers and dedicated highway bypasses.
Maps, Biomes, and Technical Specs
Trafficity includes a procedural map generator alongside distinct biome presets to offer replayable layout challenges.
- Biomes: Four biomes, each featuring unique terrain constraints and playstyles.
- Difficulty Levels: Three difficulty settings that adjust traffic pressure and economic thresholds.
- Dark Mode: Confirmed via official developer trailers, dark mode can be toggled on via an in-game checkbox to darken terrain and interface elements for low-light play.
Minimum System Requirements
Official Steam specifications confirm that Trafficity is designed to run efficiently on low-to-mid-range hardware:
- Operating System: Windows 10 (Mac OS also supported)
- Processor: 2.0 GHz
- Memory: 1 GB RAM
Frequently Asked Questions
When does Trafficity release?
Trafficity is scheduled to launch on November 16, 2026, on PC (Windows) and Mac.
Does Trafficity have pedestrian management or public transit?
No. Steam discussions and official gameplay trailers confirm the simulation is strictly focused on car, truck, and freight road management.
Can you build left-hand drive cities in Trafficity?
Yes. Official trailers demonstrate roads operating with both right-hand and left-hand traffic configurations.
Does Trafficity include a dark mode?
Yes. Onramp Games showcased an official dark mode setting that darkens terrain, road textures, and user interface panels via a simple settings checkbox.
