In toll road tunnels, the lighting at the threshold zone must balance the brightness of the access zone with natural light. Therefore, artificial lighting is strategically placed in that area to match the brightness to the intensity of natural light. This balance shifts during nighttime to ensure uniform brightness throughout the tunnel, equivalent to street lighting. Additionally, a significant amount of power is required to realize this artificial lighting. Two lamp technologies are used for tunnel lighting: HPS lamps with low energy efficiency and LED lamps with better energy efficiency. The challenge is determining artificial lighting in the threshold zone using energy-efficient lamps. To address this issue, simulations were conducted to compare the two lamp types applied in tunnels to achieve the most significant power savings. This research creates a model of toll road tunnel lighting using DIALux software better to understand the characteristics of toll road tunnel lighting using HPS and LED lamps. The SNI and ANSI/IES are the standards used. The Cisumdawu tunnel is used as the case study. The simulation results show that the luminance in the interior zone using LED or HPS lamps meets the SNI standard. Using LED lamps results in higher luminance with less power than using HPS. This discovery can improve energy efficiency in tunnel environments and contribute to lighting solutions for transportation infrastructure.
