| Abstract: |
| Due to tremendous differences of brightness, the tunnel portal is always
the place where high incidences of traffic accidents occur. If some light reduction
measures were taken in the section close to the tunnel portals, it would form an
optical transition zone which could optimize driving environment and ensure traffic
safety. Through analyzing related researches of light reduction measures applied in
highway tunnel portals, this paper introduces and summarizes the types, merits and
demerits, and application scope of light reduction measures. In addition, combining
with the domestic application status of light reduction measures utilized in highway
tunnel portals, the paper brief ly generalizes some considerable factors of light
reduction measures in practice. |
