The purpose of this study was to investigate whether various security measures in residential environments affect perceptions such as safety, beauty, and status. It was expected that some of these security measures would actually decrease perceptions of safety in opposition to their purpose. The study also investigated whether different types of individuals had different perceptions of different types of security measures—specifically whether street gates were perceived differently by individuals who lived in gated communities vs. those who did not.Subjects--Topical Terms:

520 $a The purpose of this study was to investigate whether various security measures in residential environments affect perceptions such as safety, beauty, and status. It was expected that some of these security measures would actually decrease perceptions of safety in opposition to their purpose. The study also investigated whether different types of individuals had different perceptions of different types of security measures—specifically whether street gates were perceived differently by individuals who lived in gated communities vs. those who did not.
520 $a This study involved a mail survey. Subjects were 518 residents of gated and non gated middle-class suburban communities in central California. In the survey, photographic simulation methods were used to isolate elements of security design and measure inadvertent effects that are unrelated to crime prevention. Images of residential environments—either individual residences or streets—were modified to add or remove security measures that are commonly found in these environments. Alternate test subjects were shown different combinations of the images with or without security measures in place. Each subject was shown one version of each image and no subject evaluated the same base image or modification more than one time. Subjects were asked to evaluate the images on a semantic differential using adjective pairs derived from the literature on aesthetic evaluation and perceptions of safety. These included adjectives such as safe-dangerous, beautiful-ugly, and mysterious-obvious.
520 $a As expected, many of the security measures at the scale of individual residences had a negative effect on perceived attractiveness, safety, and even status. Barrier type security measures such as fences and bars on windows may indicate increased concern about crime and hence lower individuals' estimation of the safety of neighborhoods. However, all street treatments designed to accentuate street entry such as gates and colored crosswalk pavement had positive effects on perceptions of safety, status, and attractiveness. It may be that these design elements help define a sense of territory, and at the street scale, such security measures may make a neighborhood feel more exclusive and hence higher status.
520 $a The results indicate that the scale at which a security measure is implemented may play an important role in its effectiveness in reducing fear and other perhaps unintended perceptions. Measures which are implemented at a scale more public than that of the individual residence may indicate a larger community action and hence be seen as both an effective deterrent to crime and be perceived as attractive.
