Abstract

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, to realize this artificial lighting, a significant amount of power is required. There are several lamp technologies used for tunnel lighting; one commonly used is HPS lamps, which have low energy efficiency. Currently, there are LED lamps available that are energy-efficient. 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 greatest power savings. This research creates a model of toll road tunnel lighting using DIALux software to better understand the characteristics of toll road tunnel lighting using HPS and LED lamps. The Indonesian National Standard (SNI) and ANSI/IES Rp-22-11 are the standards used. The research utilizes the Cisumdawu tunnel as a case study example. The simulation results show that the luminance in the interior zone using LED or HPS lamps, can meet the SNI standard. Using LED lamps results in higher luminance with less power than using HPS. This discovery can potentially improve energy efficiency in tunnel environments, thereby contributing to sustainable lighting solutions for transportation infrastructure.
