| Abstract: |
| In the urban environment with increasingly tight land resources, underground space
development has become an inevitable trend in urbanization construction, and underground garage
has become a reasonable response to solve the contradiction. However, many underground garages
only create the lighting environment from basic function, lacking sufficient visual identification
indicators, which has a negative psychological impact on users. The underground garage has the
disadvantages of low illumination, insufficient color rendering, and inappropriate color temperature
due to energy saving, which makes users lack the sufficient sense of security and comfort, thus
leading to users’ reluctance to use underground garage space. Moreover, while using the garages,
people often quickly leave in panic due to negative psychological feelings, with some dark spaces
inside the garage having the possibility of crime, which becomes a safety hazard.
Existing researches show that the visual recognition index of horizontal ground illumination,
color rendering index, and color temperature can affect the psychological feelings of people. Garage
design standards need quantitative visual recognition indicators to meet the needs of the user’s
psychological perception. In China’s existing underground garage lighting design standards, even if
the minimum standard value is reached, it only meets the most basic functional needs of users in the
underground garage, the psychological feeling is still more negative, and the specification lacks the
proposed value of color temperature. Therefore, it is important to find a visual identification index
that can better meet the users’ psychological feelings.
To improve users’ psychological feelings in underground garages, this paper adopts a
research method combining objective actual measurement and subjective evaluation, conducts
actual measurement evaluation and analysis of 10 typical areas in two underground garages in
Chongqing, and obtains visual recognition indexes through research actual measurement and
conducts correlation analysis combined with psychological feelings evaluation. Correlation
analysis was conducted between the physical measurement data and psychological perception
evaluation in the characteristic areas of underground parking garages. Firstly, ground illuminance,
color rendering index, and color temperature are used as factors, and multiple comparisons are
made with each psychological perception for ANOVA, and Bonferroni correction is applied after
ANOVA for the post hoc test. The ANOVA and Bonferroni correction results show that there are
significant differences between ground illuminance, color rendering index, color temperature, and
various psychological perceptions, which proves that the visual recognition lighting indexes in
this paper have some correlation with psychological perceptions. For further correlation analysisbetween visual recognition lighting parameters with significant differences and psychological feelings, since illuminance, color rendering index, and color
temperature are continuous variables, and the psychological feelings evaluation levels obtained by constructing questionnaires through the SD method
are ordered variables and evaluation scores are continuous variables, the Spearman correlation coefficient method is used for correlation analysis to derive
specific correlation coefficients. The influential elements of the psychological perception of urban public underground garage users are summarized with
visual recognition indexes.
Through the analysis, it can be found that to a certain extent, the scores of psychological feelings increase with the increase of horizontal ground
illumination. The degree of horizontal ground illumination to meet the extent of psychological feelings can be divided into four levels of standards,
in which the low standard should meet the standard value of illumination greater than 40 lx; the lower standard should meet the standard value of
illumination greater than 50 lx; medium standard should meet the standard value of illumination greater than 60 lx; high standard should meet the
standard value of illumination greater than 80 lx. In a certain degree range, the sense of interest of underground garage users with the increase of
color rendering index and rise. According to the degree of color index to meet the extend of psychological feelings can be divided into three grades
of standards, including low standards that should meet the color index greater than 70; mid-range standards should meet the color index greater than
75; high standards should meet the color index greater than 80. When the color temperature is in the 5200K-6300K range, the color temperature, and
the light sense of the psychological feeling score of the fitting curve is a quadratic function. When the size of the color temperature is in the range of
5200-6300 K, according to its psychological feeling to meet the recommended value, the best color temperature recommended value of 5700 K. It
is recommended to use a higher reflection coefficient and brightly colored materials as ground paving, to achieve a better sense of fun and sense of
dwelling. And at the same time , it sets a better color rendering light source to achieve a better psychological perception effect.
If the modified standard considering psychological feelings is adopted, it is more conducive to meeting the needs of users’ safety and comfort, improving the
happiness index, and reducing the occurrence of crimes. The research results also have important implications for similar dark indoor public spaces. |
