DOTS Traffic Core

DOTS Traffic Core is a powerful tool for creating city traffic - Design it from the ground up or customise any existing asset pack to fit your vision!

It uses the extremely powerful DOTS Entities package to simulate thousands of vehicles with unbelievable performance!

• Mobile friendly
  Simulate thousands of interacting vehicles and pedestrians, even on mobile devices.
• Performance
  Experience the performance firsthand in our various platform-specific demo projects or just check out the final screenshots to see the results.
• Rapid integration
  Integrate any city asset pack in a heartbeat with our convenient templates and tools.
• Simulation
  Simulate thousands of entities without relying on physics or raycasting (although physics simulation is also available).
• Editor
  Many flexible tools to bring life to the city of your dreams.
• Demo
  Demo sample scene included!
• Sound
  Integration of the FMOD sound engine into bursted jobs (the built-in Unity audio engine is also supported).
• Documentation
  All components of DOTS Traffic Core lite are linked to online documentation.
• Source code
  All code included.
• Vehicle controller
  DOTS physics vehicle controller included!
• You can also use Edy's, RCC or NWH & other custom vehicle controllers for both player or traffic.
• Monobehaviour support
  Not familiar with DOTS? No problem, from version v1.1.0 the project is fully compatible with mono behaviour scripts in hybrid mono mode (check out the new Hybrid Mono sample scene).
• Modular architecture
  Allows you to integrate the project into your existing game without hassles.
• Netcode For Entities
  A new demo scene showcases a network solution based on pure DOTS.
• A* navigation
  Set to follow a car to a given node using the built-in A* pathing.
• Upgrade
  The tool can be updated to DOTS Traffic City.
• 3rd-party.
• EasyRoads3D.
• Road Constructor for editor.
• MicroVerse Roads.

Key features:

Traffic

• Physics
  Vehicles can use either:
• Simple physics.
• Custom physics (custom physics controller included).
• Hybrid mono physics.
  Any monobehaviour controller can be integrated into the traffic.
• No physics.
• Speed control
  Automatic vehicle speed control depending on lane speed limit, traffic lights and other traffic.
• Lane changing
  Automatic vehicle lane changing based on traffic congestion or road type.
• Traffic groups
  Restrict lanes to certain traffic group types.
• Fast creation
  Quick and easy tool for adding any vehicle into the city.
• Avoidance
  The avoidance system makes sure that vehicles don’t collide with each other and will stop and move away if another vehicle is blocking their path.
• Obstacle Avoidance
  Bypassing a player or specified custom obstacles.
• Driving styles
  There are different types of driving styles on the road: considerate, passive, and aggressive.
• Priority
  Vehicles pass through the intersections according to road priority.
• Antistuck
  An Antistuck system that destroys the entity if it gets stuck for a while and isn't visible in the player's camera.
• Traffic Jams
  Cars won't enter crossroads if they can't get through in order to avoid causing traffic jams.
• Custom Path
  Set to follow a car to a given node using the A* pathing.
• Left-hand traffic
  Starting with version 1.1.0, driving on the left is available.
• Culling
  Vehicles only spawn around the player.
• Combined physics
  Limit physics to only the vehicles closest to the player in order to improve performance.
• LODs
  LOD system for the vehicles depending on the distance to the camera.
• Tests
  A handy traffic test scene where most traffic situations can be tested with all available parameters.

City

• Traffic road
  Multiple road templates and custom road customization tools.
• Road API
  Generate road segments from raw data or unity splines.
• Culling
  All entities in the city change their behaviour depending on the culling state (including traffic).
• Physics culling
  Only the physics objects close to the player are involved in the physics evaluation.
• Traffic light
  Quick and easy creation of traffic lights. Automatically connect hundreds of traffic lights across your entire city in just one click.
• Debug
  Convenient visualisation of data on scene.

Tools

• Road segment creator
  A Tool containing the 10 most commonly used road templates, allowing you to quickly and easily set waypoints and route settings of any complexity.
• Auto-crossroad generation
  New option to create crossroads with a single click.
• Car prefab creator
  A Tool that quickly converts 3D models of vehicles to traffic entities in just a few clicks.
• Global traffic light settings
  A tool to connect traffic lights and traffic nodes, crossroads, and visually display the timings of each traffic light on the scene.

Demo Scenes

• Demo Traffic
  Demo sample scene.
• Demo Traffic Mono
  Same scene as Demo Traffic, but all simulations run in hybrid mode of monobehaviour scripts with DOTS.
• Demo Traffic Mobile
  Mobile demo sample scene.
• Demo Traffic Mobile Mono
  Same scene as Demo Traffic Mobile, but all simulations run in hybrid mode of monobehaviour scripts with DOTS.
• Traffic Stress Scene
  A scene that is extremely crowded with vehicles in order to stress test vehicle amounts.
• Vehicle Physics Stress Scene
  Stress scene for thousands of cars with vehicle physics.
