4 DRAFT\STANDARDS\TRAF-STD\TE-0.1.dwg STANDARD TRAFFIC SIGNAL C0NSTRUCTION STANDARDS CITY OF AURORA All traffic signals maintained by the City of Aurora must be constructed in accordance with the details shown on sheets TE-1 through TE-13 as well as the following: C) Wiring (continued) 10) Loop detection lead in ("Homerun") wire shall be a 2-conductor, #14 AWG stranded tinned copper wire, polyethylene insulated twisted conductors with 100% shield coverage and stranded tinned copper drain wire.

In a case where signal poles are to be furnished as part of a traffic signal construction bid, poles shall meet current City standards and be approved by the Traffic Engineer prior to procurement. 2) Mastarm lengths shall at a minimum reach the center of the left-turn lane for each approach in the the case of single left-turn lane; or the lane line between the left-turn lanes in the case of dual left-turn lanes. In either case, the length of the mastarm shall be rounded up to the nearest 5 foot increment and indicated on the signal plan and quantities sheet accordingly. 3) Signal pole extensions and luminaire arms shall be furnished for all signal poles at an intersection unless there is an overhead obstruction such as a powerline and deviation is approved by the Traffic Engineer. 4) A typical intersection shall consist of one pole and mastarm for each approach. Multiple mastarms on a single pole shall not generally be allowed. E) Intersection Phasing/Signal Heads/Signage 1) Intersection phasing shall have phase Ø2 as either the northbound or eastbound through movement, whichever is the major street. Through movements are numbered as even phases (Ø4, Ø6, Ø8) clockwise around the intersection from phase Ø2. Left-turn phasing (where applicable) is denoted by odd numbered phases (Ø1, Ø3, Ø5, Ø7), with the following phase pairs (Ø2 Ø5, Ø4 Ø7, Ø1 Ø6, Ø3 Ø8). Unusual geometry or other conditions shall require phase approval by the Traffic Engineer. Phasing diagram shall be shown on design plans. 2) Signal heads shall be provided on both left and right poles for each direction to supplement overhead signal heads. The left side pole head shall match the leftmost overhead signal head and the right side pole head shall match the rightmost overhead signal head unless otherwise approved by the Traffic Engineer. 3) One signal head per lane, centered on the lane, shall be provided with the exception of dual left-turn lanes for which one signal head centered on the lane line between the two left-turn lanes shall be provided. Dedicated right turn lanes shall be provided with a regulatory R3-5R 30"x36" overhead sign centered on the lane in lieu of a signal head. Any deviation shall be approved by the Traffic Engineer. 4) City standard for left-turn displays shall be the Flashing Yellow Arrow (FYA) 3 section display for permissive only phasing; FYA 4 section display for protected/permissive phasing, and a 3 section RA-YA-GA display for full time protected only phasing unless otherwise approved by the Traffic Engineer. Determination of the appropriate display selection shall be made by the Traffic Engineer. 5) Dedicated left-turn lane(s) shall be provided with a regulatory R3-5L 30"x36" overhead sign or R3-5mod 48"x30" (dual left) sign placed to the right of the left-turn signal head. F) Additional Notes 1) On design plans, the lane configuration for each approach (e.g. left only, through-through-through/right) shall be shown by means of hollow arrows at the edge of the approach furthest from the intersection - these arrows are for informational purposes only and are not meant to indicate pavement markings. On the design plans, the major street shall be shown for 200' in advance of the intersection and the minor street for 150' in advance of the intersection for both directions. 2) Necessary pavement markings shall be shown as filled arrows in their appropriate locations. 3) Pedestrian movements shall be provided for all four directions of an intersection, accompanied by pedestrian heads, pushbuttons and crosswalks unless otherwise approved by the Traffic Engineer. 4) Flash program operations shall be shown on all design plans. 5) Any materials not provided by the City shall be submitted to the Traffic Engineer or designate for review and approval prior to procurement of said materials. 6) The City reserves the right to require successful demonstration of any proposed non-standard or unusual phasing or operation at its discretion. 2 of 3

5 TRAFFIC SIGNAL C0NSTRUCTION STANDARDS CITY OF AURORA F) Additional Notes (continued) 7) Once traffic signal contractor has begun work on traffic signal construction, all operations & maintenance responsibilities for the traffic signal and intersection shall shift to the contractor until such time as all work is complete and has been inspected and accepted in writing by Traffic Engineering and Operations. Additionally, the contractor shall provide a minimum one-year warranty for all work. 8) For rebuilds or modifications to existing signals, design plans shall include, at a minimum, one sheet reflecting existing conditions and one sheet reflecting proposed conditions. Additional sheets and information may also be required at the Traffic Engineer's discretion. 9) For new traffic signal construction, the signal shall be placed into flashing operation a minimum of 48 hours prior to the activation of full operation. Both flash and full turn-ons shall occur on Tuesdays, Wednesdays, or Thursdays only on non-holiday weeks only unless otherwise approved by the Traffic Engineer. For traffic signal rebuilds or modifications, changeovers from old equipment to new equipment shall only occur between 8:30am and 3:30pm on Tuesday, Wednesday, or Thursday only on non-holiday weeks only unless otherwise approved by the Traffic Engineer. 10) Any traffic signal or pedestrian indications that are under construction and are not active shall be covered with ORANGE bags until such time as they are placed into service. Any pedestrian pushbuttons that are under construction and not active shall have the associated signage placed blank side out and the buttons covered until such time as they are placed into service. Crosswalks shall not be marked at new traffic signal installations until such time as the traffic signal is placed into full operation but shall then be marked on the same day or as soon as possible afterward. Any deviation from the above must be approved by the Traffic Engineer. 11) For all new traffic signal installations punchlist inspection shall be scheduled and coordinated with Engineering, Inspections, and Operations. All punchlist items shall have been addressed and confirmed corrected and the traffic signal to be 100% complete prior to flash turn-on. The City will not assume ownership, maintenance, and operation of the new traffic signal until such time as the punchlist has been verified complete, the signal has been placed into full operation, and the signal has been formally accepted in writing by Operations. A minimum one-year warranty shall be provided for all new traffic signal installation work. Any deviation from the above must be approved by the Traffic Engineer. 12) Video detection (camera) placement and mounting type to be determined by the manufacturer and/or vendor for optimal location and performance of the product, subject to approval by the City of Aurora. This will be a vehicle lane approach specific determination. DRAFT\STANDARDS\TRAF-STD\TE-0.1.dwg 3 of 3
