hear1ngs and discuss10ns for traffic controls, 1t 1S deemed necessary to
set minimum standards for the installation of traffic control devices; and
WHEREAS, recognizing the pr1nc1ple that stop Signs are not a
Subst1tute for speed regulations and other regulatory measures, but are
intended to facilitate the orderly flow of traffic at intersections and
further recognizing the principle that indiscriminate use of stop Signs
tends to hamper rather than a1d in the safe and efficient flow of traff1c,

to create disrespect for stop signs in general and will tend to lessen the
self-enforclng adherence of the general public to compliance with the stop
sign installation; and

safety and environmental health of resident1al neighborhoods in the City
