Problems solved by technology
[0003] The direct reason for the sharp change of illumination at the entrance and exit of the tunnel is actually the illumination within the range of 50m from the entrance and exit of the tunnel. The change speed of the driver's pupil area can be used as an evaluation index for driving safety at the entrance and exit of the tunnel, and the sharp change of illumination will cause driving The pupil area of the driver changes rapidly, which further leads to the occurrence of traffic accidents

Embodiment
[0018] Embodiment: This embodiment is mainly aimed at the situation of large vehicle exhaust and high humidity in the tunnel, and develops a light guide lighting system and lighting technology suitable for this environment.
[0019] like figure 1 As shown, the lighting layout of the tunnel entrance section 1 is arranged from dense to sparse. First, a number of illuminators 4 are arranged in the entrance section 1 so that the illuminance of the tunnel entrance section 1 on the road surface outside the tunnel can be initially reduced (the reduction coefficient meets the corresponding tunnel lighting design specifications), and the entrance section 1 is followed by the transition section 2 and the transition section 3 , where the arrangement spacing area of the illuminators 4 in the transition section 2 is larger than the arrangement spacing area of the illuminators 4 in the entrance section 1, and the arrangement spacing area of the illuminators 4 in the transition section...

The invention relates to the field of tunnel engineering, in particular to a method for laying a tunnel portal strengthened illuminating system. The method is characterized in that a plurality of illuminating devices are arranged in an entrance section and an exit section, and the illuminating devices arranged in the entrance section or the exit section are distributed in a thinning mode from a tunnel portal to a distribution area in a tunnel, namely the illumination level is reduced gradually from the tunnel portal to the inside of the tunnel. The method for laying the tunnel portal strengthened illuminating system has the advantages that the laying scheme is acquired by setting up a testing shed in the site to analyze, compare and select data of a plurality of schemes, and light guides are arranged in the entrance section and the exist section of the tunnel by the laying scheme to replace high strength gas-discharge light sources, so that the gentle transition of the illumination levels on road surfaces inside and outside the tunnel is realized, and the zero electric energy loss of tunnel strengthened illumination is realized.
Description
technical field [0001] The invention relates to the field of tunnel engineering, in particular to a method for laying out a reinforced lighting system at a tunnel entrance. Background technique [0002] Current research shows that tunnel entrances and exits are the main road sections that form accident black spots. The sharp change of illumination at the entrance and exit of the tunnel greatly increases the driver's visual psychophysiological complex, induces bad driving behavior, and even leads to traffic accidents. However, at present, domestic scholars' research on highway tunnels is mainly focused on the current safety design and the theory and method of driving sight distance, lacking the support of driving tests, and lacking tunnel samples. [0003] The direct reason for the sharp change of illumination at the entrance and exit of the tunnel is actually the illumination within the range of 50m from the entrance and exit of the tunnel. The change speed of the driver's ...
