Play and help the city to get rid of traffic jams! Do you remember having to stay at the intersection on red for too long or being stopped at every traffic light? If so, this game is definetly for you. Choose an intersection and take control of it. You will be setting up real intersections, no fictions. The first three intersections are FREE! - Change the priority signs and adjust the duration of the red and green signals at the intersection to unload roads and get rid of congestion. - Install new traffic lights and road signs to achieve better performance. - Change the configuration of the traffic light (for example, add an additional sections) to make traffic easier. - make two intersections connected in a green line so that cars are able to pass without stopping at red - this will reduce congested sections. When your result appears in the top rating, we will be able to affect the real traffic: we transfer the best results to local authorities. We guarantee pleasant bonuses. By now you are suppose to stop complaining and to take part in the traffic control. All this in the form of a game! It's simple: choose the intersection of interest on the map and start. If your intersection is still being worked out, you can speed up the process: make a donation to give us additional motivation to prepare it! We have already worked out all the most important intersections in Kharkov, Ukraine, in the near future we are launching new intersections for Kiev. We constantly update the database and add new ones. Try to set up the perfect intersection.
