SECTION 6 – TRAFFIC AND LIGHTING <br />85 <br />6-3.3 TRAFFIC SIGNAL CABINET AND FOUNDATION <br />A Type P-1 foundation shall be provided for a TS2 Cabinet. All Cabinets shall come provided with all <br />necessary equipment to function properly and shall provide an Ethernet switch. The Type P-1 foundation <br />shall be in accordance with INDOT Standard Drawings. <br />6-3.4 CONTROLLER AND CABINET LOCATION <br />Traffic signal cabinets shall be located to provide easy access for operation and maintenance while <br />minimizing impacts by errant vehicles. Refer to Standard Drawing 6-5 for guidance on location of <br />controller cabinets at signalized intersections. Lighted intersections shall consider a tree canopy for <br />photocell operation. <br />Each time a controller cabinet door is opened, records are to be kept for why the door was opened. <br />New traffic signal installations shall include a cabinet log for documentation purposes. <br />6-3.5 ACCESSIBLE PEDESTRIAN SIGNALS <br />The use of an Accessible Pedestrian Signal (APS) shall be considered at locations where a visually <br />impaired pedestrian has made a request or at locations where a visually impaired pedestrian is present. <br />APS shall also be considered at an intersection adjacent to traffic signals that currently have, or will be <br />equipped with, APS. An Accessible Pedestrian Signals (APS) Study Report shall be conducted for any <br />new traffic signal installation and shall be submitted for review to Engineering. <br />6-3.6 SIGNAL HANDHOLES <br />The maximum spacing between handholes in the same conduit run is not to exceed 200 feet for lighting <br />and 300 feet for fiber circuits. Desirably handholes shall not be located within the pedestrian access route. <br />If site restrictions require, handholes shall have a casting that meets section R302.7 in the ADA PROWAG <br />regarding vertical alignment and surface discontinuities. <br />No cable splices shall be permitted anywhere below surface grade. The cover of the handhole shall be as <br />shown on Standard Drawing 6-19. <br />Handholes should be located within the tree-lawn area when possible. Other locations may include <br />sidewalks, behind guardrails or non-mountable curb, paved shoulder, or as directed by Engineering. <br />Handholes shall not be located within the curb ramps. The handhole shall be made of concrete in <br />accordance with INDOT Standard Drawings. Handholes made of polymer concrete are not allowed. <br />A handhole that needs to be placed directly in a travel lane will require a special design and plan detail to <br />provide a means by which the cover and ring are to be secured to the handhole. <br />6-3.7 CONDUIT <br />Conduit shall have a minimum diameter of three (3) inches or equivalent area with no greater than thirty <br />percent (30%) of the interior area filled by wiring. Two (2) additional conduit runs shall be install from <br />the controller cabinet foundation to first handhole. Conduits for advanced detection may have a minimum <br />diameter of two (2) inches.
