Eurasia Tunnel is a V-Shaped TBM tunnel connecting Asian and European sides of Istanbul by reaching its deepest point at 106 m from sea level with a longitudinal slope of 5% in accordance with the highway standards. Free flow without any traffic congestion along the tunnel is one of key elements for traffic management not only traffic safety, but also good qualify of driving satisfaction in the tunnel. It has been observed that traffic flow speed decreases and light traffic congestions at the middle of the tunnel which cause increase in traffic density at the deepest point of the tunnel and the following uphill section due to sudden brake, wrong gear and/or wrong speed choices of the drivers. This study will discuss the Pacemaker Lighting application started in Eurasia Tunnel in June 2020, -which is a speed regulating moving light reflected on the ceiling of the tunnel by using LED fixtures-. This application aims to guide users for a smooth acceleration and following distance, to avoid undesirable traffic jams, to prevent potential traffic accidents, engine/transmission breakdowns and to decrease level of vehicle emissions. This paper also reports the sustainability provided by the system with the results of the application such as significant speed and efficiency increase in the Pacemaker Lighting Zone, significant decrease in the number of traffic speed decreases and vehicle emissions in 11 months of operation time.
