This local transport note recommends good practices for installing permanent traffic signals and associated equipment. Guidance is also given for the installation of temporary traffic signals.
The traffic signal heads are in most cases the only part of the whole traffic signal system that the motorist actually sees. Therefore, the vertical and horizontal positioning and the directional orientation are critical to a well functioning system.
When inspecting the installation of traffic signal heads, the following items are required to considered: 1) The Basis For Approval for signal heads and. Loop Installation Guidelines (Cont.) When the outline of the loop and lead-in has been marked, the pavement can be cut.
Diamond blade cutting saws are recommended. The saw cut should be approximately inches deep and inches wide. The saw slot should then be cleaned out and allowed to dry.
Compressed air is useful both for ejecting debris and. For example, the International Municipal Signal Association (IMSA) is the oldest traffic signal installation and maintenance agency in the United States, having been in existence for more than years.
It is recognized as the leading agency for certifying individuals in the installation and maintenance of traffic signals nationwide.
CHAPTER 29 TRAFFIC CONTROL 29 TRAFFIC CONTROL The green book (OHSA and Construction Regs) makes it mandatory for traffic control persons (TCPs) to be protected from hazards.
