Complete City Traffic & Pedestrian System v1.5.5 (Latest version)
“If possible, please buy the package to support the developer”
Description
Bring your city to life with the Complete City Traffic & Pedestrian System — a unified urban ecosystem where intelligent traffic and reactive pedestrians seamlessly share streets, intersections, and crosswalks.
This bundle combines the full power of Mobile Traffic System and Mobile Pedestrian System into an integrated framework. Because both systems are engineered around the same high-performance architecture, vehicles automatically stop at traffic lights, yield at crosswalks, overtake slower traffic, and safely interact with pedestrians right out of the box.
Whether you are building an open-world driving game, city simulator, racing game, roleplay experience, or urban sandbox, this package provides everything needed to create believable, high-density living cities in minutes instead of months.
📦 Complete Urban Ecosystem: Everything you need to create a living city in one purchase — two independent assets that work seamlessly together or separately.
⚡ Mobile-Grade Performance: Handles hundreds of combined vehicles and pedestrians on 2018 mobile hardware while remaining scalable for large open-world PC environments.
🧠 Production-Ready City Simulation: From emergency vehicle priority and zipper merges to smart crosswalks and dynamic pedestrian routing.
💰 Save $24 Instantly: Get the complete pre-integrated city simulation ecosystem and save $24 compared to purchasing both assets separately.

🛣️ Shared Intersection & Road Behavior
Traffic Light Intersections: Synchronization between vehicles and pedestrians at shared intersections—cars automatically stop on red while crowds get the walk signal, entirely out of the box.
Priority Intersections: Vehicles and pedestrians independently decide whether to wait, yield, or enter.
Crosswalk Behavior: Vehicles smoothly brake and wait for crossing pedestrians.
Roundabout Support: Vehicles wait until the roundabout is clear before entering.
Complex Give Way: Designate specific waypoints that must be clear before a vehicle can enter an intersection.
Zipper-Style Give-Way: Vehicles take turns advancing when a multi-lane road converges or narrows.
Zone & Type Restrictions: Restrict road and area access by vehicle or pedestrian type (e.g. trucks on outer lanes only; only students inside campus zones).
Speed Routes: Apply global or lane-specific speed limits across any area of your scene.

🧠 Combined System Intelligence
Emergency Vehicle Priority: Traffic and pedestrians automatically clear the way for ambulances or other designated special vehicles.
Overtake & Lane Selection: Vehicles automatically check adjacent lanes and safely overtake slower traffic and stationary players.
Obstacle Avoidance: Pedestrians navigate smoothly around both fixed environment assets and moving objects.
Custom Behaviors: Create and assign custom behaviors for both vehicles and pedestrians without modifying core code.
Autonomous Decision Making: Both vehicles and pedestrians independently decide when to stop, yield, merge, cross, and enter intersections safely.

🗺️ Pathfinding & Navigation
Waypoint-Based Pathfinding: Both vehicles and pedestrians navigate waypoint networks with full branching support.
Shortest Path Calculation: Automatically find the quickest route between any two waypoints in the scene.
Direct Path Following: Assign a specific route for any vehicle or pedestrian to follow programmatically — perfect for linear traffic patterns or scripted story events.
Destination Routing: Send any vehicle or pedestrian from anywhere in the scene to a specific destination via API.
Priority Waypoints: Balance city populations by assigning custom importance weights to roads and pathways — automatically creating high-density traffic downtown while thinning out secondary side streets.
Custom Waypoint Events: Trigger dynamic script actions the moment a vehicle or pedestrian reaches a marked waypoint.
