Recent advances in tunnel infrastructure have emphasized safety, operational efficiency and low operating costs. Modern tunnels are equipped with systems to improve both safety and operational performance. This study investigates the effect of tunnel lighting and vehicle breakdown scenarios on driver lane changing behaviour (LCB) using a driving simulator modelled on the third longest twin-tube tunnel. Data were collected from 125 drivers considering various driver characteristics with different lighting conditions and the presence of a stopped vehicle in a lane. The results show that drivers tend to slow down and change lanes more safely in response to red and flashing lights. In contrast, blue sky lights, which are designed to reduce stress and compare with other dangerous scenarios, had no significant effect on LCB. In addition, demographic factors such as gender and previous simulator experience played a role in influencing LCB tendencies. Female drivers and those familiar with simulators showed more cautious behaviour. The findings showed valuable insights into how tunnel lighting systems can improve safety. Results highlighted the potential for dynamic lighting and targeted driver training programs to improve tunnel safety. All these findings may contribute to ongoing efforts to improve traffic management and reduce accidents in tunnel environments.

Çakmak, Recep; Dündar, Ayhan
This study presents the design and implementation of a computer-based real-time demonstration setup for dynamic highway tunnel lighting control research studies. The energy-efficient and controllable lighting systems stand out worldwide because of energy efficiency objectives and carbon footprint reduction goals of the countries. An LED (Light Emitting Diode) armature-based highway lighting systems are frequently utilized in recent years due to lighting efficiency, energy efficiency, long life, environmentally and cost-friendly structure of the LEDs as well as zero ultraviolet emissions of them. In this study, the LED-based dynamic tunnel lighting control approach has been implemented through the proposed demonstration setup which is a typical real-time software-controlled hardware. The parts of the proposed demonstration setup have been introduced and detailed to help with some upgrade studies in the future. The demonstration setup has been tested in some case studies, then the obtained results have been discussed and introduced. In the future, the proposed system can be upgraded and utilized for advanced control studies thanks to its computer-based and simulation environment connection capability.
