In Tashkent, Uzbekistan, drivers have gained the ability to move more easily along one of the busy sections of the Small Ring Road thanks to the implementation of the 'green wave' system. Twelve traffic lights were synchronized, allowing vehicles traveling at a speed of 50–60 kilometers per hour to cover about five kilometers with minimal stops. This provides drivers with less waiting time at traffic lights and faster passage.
The system was launched on a section stretching from the pedestrian crossing in front of the Uzbek State University of World Languages to the crossing opposite the Visol banquet hall, in the area where it intersects with Sheikh Zainiddin Street.
Before the traffic lights were adjusted, travel along this section took an average of 11 minutes and 30 seconds. After the system was implemented, the time was reduced to 9 minutes and 40 seconds, which means saving approximately 1 minute and 50 seconds per trip. Although the difference seems small, under urban traffic conditions, these nearly two minutes lead to a reduction in the number of stops and restarts, allowing the driver to move more uniformly along the entire section.
Assuming ten such trips, the total time saved will reach about 18 minutes. For those who regularly use this route in both directions, the accumulated savings over time will increase to tens of minutes.
The system's operation is based on traffic light synchronization: if the driver adheres to the recommended speed, they enter a sequence of green signals and can pass intersections without constantly stopping.
Representatives of the Tashkent Traffic Organization Center announced plans to continue implementing the 'green wave' in other parts of the capital where traffic intensity is high. Previously, a similar principle was applied to synchronize the operation of 11 traffic lights on Mahtumkuli Street, which led to a 12% increase in the throughput of this artery and a 10% reduction in average travel time.
