The lighting of road tunnels and underpasses is one of the most critical tasks when dealing
with illumination due to, at least, two reasons. On one hand, the slightest visual impairment …

The emergence of digital twins has ushered in a new era in civil engineering with a focus on
achieving sustainable energy supply, real‐time sensing, and rapid warning systems. These …

Tunnel lighting consumes nearly 30% of the energy in the whole infrastructure, so optimizing
the lighting control strategy could significantly increase the energy utilization efficiency …

The transfer of solar light to the interior of tunnels to complement electrical lighting during
daytime, contributes to save energy and decrease the number of installed projectors. The …

The lighting design of a road tunnel focuses on the setting of pavement luminance. As for the
tunnel sidewall luminance, it simply follows the principle of no less than 60% of the …

Introduction Disability glare from lighting systems is considered to be one of the main causes
of accidents in road tunnels. The present study aimed to investigate the estimated method of …

Supplying the electric loads of road tunnels is a complex problem that should consider
safety and sustainability aspects. This position paper presents an ongoing project on the …

To achieve energy saving and safe driving in a tunnel, this work proposes a tunnel
intelligent dimming control and energy consumption monitoring system. Firstly, a dynamic …

Although dimming the light in tunnels brings salient benefits to energy saving, the effects of
dimming-induced luminance changes on driving safety have been rarely explored. Adopting …

In the paper, an embedded system dedicated to control lighting of the workplace is
proposed. The construction of the considered lighting system with a power LED (Light …
