Evaluating tunnel lighting impact on driver safety and comfort via driving simulation
The development mode of transportation infrastructure construction has shifted from pursuing speed and scale to prioritizing quality and efficiency.As a result,there has been an increasing demand for fine-tuning and adapting the tunnel lighting environment,which should prioritize the safety and comfort of drivers.Based on tunnel lighting theory and driving behavior researches,eight indicators that affect driver safety and comfort were selected to establish a driving safety and comfort evaluation system.Indoor simulation was conducted through tunnel driving sim-ulation environment and hardware facilities.A virtual simulation model of the tunnel was established using UC-win/Road software,and data corresponding to the eight indicators were obtained through driving simulators and physio-logical instruments.Then the entropy method was used to determine the weights of the indicators,and the driving safety and comfort in the tunnel under different lighting brightness and color temperature environments were evalua-ted.The target value of brightness and color temperature in the tunnel were obtained with the goal of achieving the optimal value of driver safety and comfort.The experimental results confirm the effectiveness of the driver safety and comfort evaluation system,propose an improved tunnel lighting scheme,and provide reference for tunnel operators.
