ODOT Inspector’s Manual For Signal Construction 2015

183

Reading Plan Sheets Standard drafting symbology is used in signal design to represent common equipment, providing valuable information to the user without using any text. As such, the user should become familiar with the standard symbols and line styles. Bubble notes are used in conjunction with the standard drafting symbology to provide the specific information about the installation. The bubble notes have been designed to be “intelligent”, such that an experienced user will be able to read the signal plan sheets without much assistance from the bubble note legend text. For example:

Bubble notes use abbreviations for equipment that can be defined entirely by the bubble note legend text:

Bubble notes use abbreviations AND variables (shown in pink) for equipment that must be further defined by where/how it is used:

Regardless of experience level, it is always advised to read the bubble note legend text at least once because changes in text may occur. For example:

VS.

If there is conflict between symbology and the bubble note, contact the Engineer of Record for clarification.

“C” abbreviation for “Controller” and “2070” indicates the model

Variable is always defined in (text)

“SM” abbreviation for “Signal Mast arm pole” and “T” is the variable

Poles are labeled consecutively for entire project

Signal head type (2) & mount type (B) info on leader‐line

Sign mount type (AB) info on leader‐line

On this Type SM4 signal pole: A 40’ mast arm, two pedestrian indications (phase 2 & phase 4), two push buttons (phase 2 & phase 4), one terminal cabinet, and one sign.

Install phase 4 vehicle signal

Replace variables in text when reading: “Install channel (D), (1) barrel fire preemption detector unit”

Detailed on other plan sheet: not paid under traffic signal bid item

NOTE: Curb ramps and pushbuttons not shown to current standard!

In this 1½” conduit: 1 No. 8 AWG THWN wire (common) 13 No. 14 AWG THWN wires (3 spare wires for

phase 4 are inclusive to this wire count) one fire preemption detector feeder cable

(Channel D)

4 conduits enter this junction box: Two conduits defined on

detector plan, and Two 1 ½” conduit

2 conduits in this trench (one 1½” and one defined on the detector plan)

3 spare wires for phase 4 are inclusive to the number of wires listed below (13 No. 14 AWG)

In this 1½” conduit: 2 No. 6 AWG XHHW wires. Typical wiring between the BMCL & controller cabinet. (Bonding wire also required by specifications – not shown on plans)

In this 1½” conduit: 4 No. 10 AWG XHHW wires (for illumination fixtures)

3 No. 12 AWG THHN wires (for photo electric cell)

Illumination wiring ALWAYS bypasses the controller cabinet

Photo electric cell located on pole No. 3

There are 4 conduits in this trench. Three conduits carry all the wiring going directly into the controller cabinet. One conduit is for future use (CS).

Power Source

Conduit & wiring from the power source to the BMCL is always according to the requirements of the power company (permit)

Wiring for photo electric

cell

Any changes to temporary lane use

may require modification to the signal indications or phasing. ALWAYS contact EOR for

options. The signal head type (2) is located on the leader‐line

This portion of span wire (between the pole and the signal indication) has: 6 control cables

with 7 No. 14 AWG conductors

Two fire preemption feeder cables (Channel B & C)

This portion of span wire (between the pole and the Fire Preemption unit) has: 3 control cables with 7 No. 14 AWG

conductors one fire preemption feeder cable

(channel B)

Permanent signal symbology may be shown

to provide reference

NOTE: Curb ramps and pushbuttons not shown to

current standard!

Loop No. 12 for phase 1

2 pairs of loop wires (one from loop No. 13 & one from loop No. 14) are entering the 2” sand

pocket block out

In the 3” conduit there is a total of 14 loop feeder cables

(2+1+4+2+1+4)

1 pair of loop wires (from

loop no. 12) is entering the 2” sand pocket block‐out

1 loop feeder cable for phase 1 (for loop No. 12)

Replace variables in text when reading: “Install (2) phase (1) loop feeder

cables”
