Traffic System

Nominated for Best Development Tool on the Asset Store at Unity Awards 2021

• Trucks with trailer support.
• Pathfinding on waypoints. Method to find the shortest path between 2 waypoints using the existing waypoints inside the scene.
• The ability for traffic vehicles to follow a given path. Method to make any vehicle form anywhere in the scene to reach a specific destination.
• Overtake – cars automatically overtake each other if the road has multiple lanes.
• Traffic vehicles will clear the way for ambulances or other special cars if specified.
• Traffic lights intersections support.
• Priority intersections support – cars decide by themselves to wait or to enter an intersection.
• Roundabout support – cars wait until the roundabout is free.
• Narrow road support – cars wait until the lane is free before changing it.
• The Complex Give Way feature allows developers to designate specific waypoints that must be clear for a vehicle to enter an intersection. This capability is particularly useful for scenarios where there’s a larger priority road intersected by a smaller side road. By utilizing Complex GiveWay, developers can establish this setup without creating a traditional intersection.
• Zipper style give-way. Useful when a multi-lane road converges or narrows. Vehicles take turns advancing into the narrowed road alternately.
• Building avoidance – if a car hits a building, it will try to recover itself.
• Player component. A script that makes traffic vehicles give priority to the player in an intersection. Additionally, it provides the capability for traffic vehicles to overtake the player’s car.
• Customizable vehicle properties – acceleration, max speed, brake speed, steer angle etc.
• Variable number of wheels – from 3 to as many as you want.
• Automatically car assignments – made just by pressing a button.
• Speed routes – set speed restrictions for some lanes or areas and all cars will follow them.
• Car types – assign different types to cars and you can restrict access on some roads based on car types (ex: trucks are allowed only on the first lane and are not allowed inside the cities).
• Priority waypoints. Ability to set the importance of the roads. Useful to spawn more vehicles on the main roads and fewer on secondary roads.
• Lights support – main, brake, blinkers, and reverse lights that work automatically.
• Sound support – basic engine sound for each car based on acceleration and speed.
• Hard shadow support – useful if you need even more performance.
• Custom events on waypoints. Those events are triggered when a vehicle reaches a specially marked waypoint. Useful for dynamic actions inside the app.
• Switch the direction of the entire waypoint network with a single click (currently in beta). Used for right-hand and left-hand traffic scenarios.
• Capability to programmatically make a traffic vehicle to change lanes.
• Ability to override the vehicle behavior from the API.
• Capability to have vehicles inside the vehicle pool that will not be instantiated by the system. They need to be programmatically instantiated at the right time.
• Ability to subscribe to various events for a better overview of what happens inside the system and better customization opportunities.
• Added delegates for some actions to easily change the default behaviors used by the system.
• Custom editor tools – many editor windows to make the integration process as smooth as possible.
• Simple API for advanced functionalities.
• Complete code included and commented.
• Works for any platform that supports the Burst compiler.
• Requires Unity 2021.3 LTS and above

All that you see in the demo is included inside the package:

• 1 mobile production ready car with 3 LODs and changeable colors, thanks to PolyNinja
• 9 road tiles that can be assembled in any way to create complex roads.
• 20 simple city buildings to populate your environment.
• 1 demo scene that assembles all the above elements into the playable scene from the demo.
