659-1 Description.
Furnish and install mounting assemblies for vehicular and pedestrian traffic signals, signs, cameras, detectors, and other devices in accordance with the Contract Documents.
659-2 Materials.
659-2.1 General: Use mounting assemblies that meet the requirements of Section 995
and are listed on the Department’s Approved Product List (APL). Meet the requirements of Section 603. Fastening hardware such as bolt s, nuts, washers, set screws, studs, u -bolts, cable and cable swags, must be provided by the mounting assembly manufacturer, must be SAE Type 316 or 304 stainless steel. Hardware (studs, bolts and u -bolts) must be a minimum of 5/16 inch diameter unless oth erwise specified in this Section. SAE Grade 8 bolts and nuts are also acceptable.
659-2.2 Mast Arm Mounting Assemblies: Mast arm mounting assemblies must include
the following components: mast arm saddle, swivel, attachment cables (with cable clamp mechanism) or bands, support tube, and top and bottom support arms.
659-2.3 Span Wire Mounting Assemblies: Span wire mounting assemblies must
include a span wire clamp, a hanging device such as a drop pipe, adjustable hanger, or adjustable pivotal hanger with e xtension bar, messenger clamp, disconnect hanger, and multi -brackets.
659-3 Installation.
Install all mounting assemblies and torque all fastening hardware in accordance with the manufacturer’s recommendations. When connecting the extension bar to the to p and bottom parts of the adjustable hanger, use maximum overlap of the two pieces and use a minimum of two bolts to connect the top and bottom portion of the hanger to the extension bar, separated with one hole between the top and bottom.
659-4 Warranty.
Ensure mounting assemblies have a manufacturer’s warranty covering defects for a minimum of three years from the date of final acceptance in accordance with 5 -11 and Section 608. The warranty must include providing replacements, within 10 calendar days of notification, for defective parts and equipment during the warranty period at no cost to the Department or the maintaining agency.
659-5 Method of Measurement.
The Contract unit price per assembly for each mounting assembly, furnished and installed, will include all materials specified in the Contract Documents and all labor, equipment, and miscellaneous items necessary for a complete and acceptable installation. No separate payment will be made for mounting assemblies for new installation s. All incidentals required by the Plans for new installations, including mounting hardware, will be included in cost of the new signal, sign, camera, detector, or other traffic control device.

660-2.2 Classification of Types: Vehicle detection and data collection systems are
classified by the type of function they perform and the type of technology that they employ.
660-2.2 1 Functional Types: Provide the functional type detailed in the Plans.
660-2.2 1.1 Vehicle Presence Detection System s: Vehicle presence
detection systems produce a corresponding output any time that a vehicle occupies the physical or virtual area of the detector.
660-2.2 1.2 Traffic Data Detection System s: Traffic data detect ion
systems provide presence, volume, occupancy, and speed data for the lanes they are configured to monitor.
660-2.2 1.3 Probe Data Detection Systems: Probe data detection systems
provide speed data and travel times for a road segment. Probe data detectors use automatic vehicle identification (AVI) technologies to establish a unique identifier for each vehicle they detect. Thi s identifier is then transmitted to a central site where it can be matched to past or future detections of the same vehicle at different detector locations.
660-2.2 1.4 Wrong Way Vehicle Detection Systems: Wrong way vehicle
detection systems produce an alarm output when a vehicle is detected traveling in the wrong direction and may consist of more than one detection zone and may use any of the technology types. For both mainline and ramp installations, the detection system must monitor all lanes for one direction, including shoulders. The wrong way detection system must not interfere with other vehicle presence or traffic data detection systems.
660-2.2 2 Technology Types: Provide the detection technology type detailed in
the Plans. Detection technology types include inductive loop, video, thermal, microwave, wireless magnetometer, and AVI systems.
660-2.2 2.1 Inductive Loop: An inductive loop detection system uses a
minimum of one inductive loop and loop detector. The system operates by energizing and monitoring wire embedded in the road surface to detect vehicle presence and provide an output FY 2023-24 Return to Table of Contents
