Take control of the traffic lights and keep vehicles flowing smoothly through each intersection. Here’s how:
INTERACT: Click or tap a traffic light to change its state (red → green → yellow).
TIMING: Adjust switching rhythm to clear queues without causing collisions.
MONITOR: Watch all lanes and pedestrian crossings to avoid pile-ups.
LEVELS: Each stage adds more lanes, turns, and faster vehicles—adapt your strategy accordingly.
GOAL: Prevent crashes, minimize waiting time, and reach the target score for each level.
Prioritize clearing the longest queues first to reduce overall waiting time.
Stagger green lights for adjacent lanes to avoid gridlock in complex intersections.
Use short yellow phases only when traffic is light longer yellow helps during high traffic.
Watch for emergency vehicles or speeding cars and give them temporary priority.
Pause between switches when pedestrians cross to prevent accidental collisions.
