REAL-TIME TRAFFIC CONTROL SYSTEM

Description: This item shall consist of furnishing, installing, maintaining, relocating, and removing an automated real-time traffic control system (RTTCS) meeting the requirements noted herein and providing the maintenance of the system during the duration of the work.

The Contractor shall furnish said system for measuring and delivering condition-responsive alerts on the project. The RTTCS components shall be installed at the locations shown in the plans.

The RTTCS shall be installed and operational two weeks prior to any lane closures on the project and shall remain in place until directed by the Engineer to remove the system or a portion thereof.

The RTTCS shall consist of, at a minimum:

• A Real-Time Traffic Control Monitoring Sensor Unit. Each sensor shall be capable of communicating with other components of this system.

• A Real-Time Traffic Control Warning Sign. Each unit shall consist of:

• Warning signs with sign legend as shown in the plans.

• Each sign shall have amber wigwag LED flashing lights (two flashers per sign) attached, with a minimum lens size of 12 inches. The flash pattern and flash sequence shall comply with the MUTCD, Chapter 4L.

• Remote communication hardware and software and controllers capable of activating flashing beacons.

• One real-time traffic control central base unit equipped with appropriate hardware, software and dedicated network connection. To maintain accurate and reliable communication between all components of the system.

The exact locations of all devices shall be determined as part of an on-site communications analysis with the Contractor.

The RTTCS shall meet the following specifications:

• The RTTCS shall be a proven system that has been successfully deployed and operated in actual work zone and congestion areas.

• The RTTCS shall be capable of identifying stopped / slowed traffic conditions. The system shall self-test for communication or sensor failures.

• The RTTCS shall operate continuously (24 hours, 7 days a week) when in place and visible to the motoring public.

SECTION (15-22VB)BR

• The traffic sensors shall be of a type whose accuracy is not degraded by inclement weather or degraded visibility conditions including, but not limited to precipitation, fog, darkness, excessive dust and road debris.

• The RTTCS shall be capable of acquiring traffic data for a minimum of two lanes of traffic in the same direction.

• Traffic sensors shall sequentially activate the warning sign flashers as the queue extends and be capable of only activating specific warning sign flashers.

• The RTTCS shall be capable of activating a message board.

• The RTTCS shall utilize static signs with two wigwag flashing beacons that only activate when slowed or stop traffic is detected to convey real-time traffic condition information to motorists.

• The warning sign flashers shall activate whenever the average traffic speeds fall below 30 mph and turn off when the average speed returns to above 45 mph. These speed thresholds shall be capable of being changed based on actual field trials and the location of the traffic sensor.

• Warning signs expected to be in place for more than two weeks shall be post mounted.

• The RTTCS shall have a reliable communication system and provide warnings to the system manager and the Engineer when communication or device failures are detected.

• The RTTCS shall be capable of notifying the Resident Engineer and Communications Center when the flashing beacons are activated.

• The RTTCS and flashers shall have a reliable power source.

• The RTTCS shall allow authorized users remotely to manually override the system during apparent system failures.

• Critical system operator control functions shall be password protected.

• The RTTCS shall have reporting features to a secure website. The website shall, at a minimum, show the current speeds at each detector location and whether the warning flashers are activated. The website shall provide access to archival data for the duration of the project. This data shall be printable.

• The RTTCS shall provide data logging the system events and key detection data. The data is to include the dates and times that the system was activated, which signs were activated, duration of the activation, and average speeds at each detections device. The data shall be provided to the Engineer at the close of the project in Microsoft Excel ®, latest format.

• If during the duration of the project, it is found that the distances or locations in relation to each other and/or to the taper, detectors or warning signs need to be relocated due to a change in the traffic conditions or queuing patterns, a one-time adjustment is included in the cost of the Real-Time Traffic Control Monitoring Sensor Unit.

• The RTTCS components may be relocated as deemed necessary by the Engineer

• During winter shut-down all trailers shall be removed from the right of way and the signs shall be removed as directed by the Engineer. All removal, storage, and reinstallation shall be included in the cost of the Real-time Traffic Control Monitoring Sensor Units.

System Performance: After the RTTCS is in place and operational, knowledgeable Contractor personnel shall be available for one work week (until Friday at 8:00 PM) after the lane closures are in place to ensure that the system is functioning properly. The responsible individual shall be capable of responding within 15 minutes during the first week and shall have sufficient resources to correct any issues with the RTTCS at that time.

To ensure a prompt response to incidents involving the integrity of the RTTCS devices, the Contractor shall provide a telephone number where a responsible individual can be contacted on

SECTION (15-22VB)BR

a 24-hour-a-day basis. The Contractor shall dispatch sufficient resources within two hours of notification to make needed corrections of deficiencies. All deficiencies shall be corrected within 12 hours. If the Contractor fails to restore the RTTCS to full operation within the time limits specified above, the Engineer will impose a daily monetary traffic control deficiency deduction for each calendar day (or portion thereof) the deficiency exists, as described in Article 105.03 of the Standard Specifications.

Additional real-time traffic control sensor units installed as directed by the Engineer after the initial deployment of the system shall be in operation and accepted by the Engineer within 14 calendar days after the Contractor receives written notification of changes from the Engineer. If the Contractor fails to update the RTTCS to full operation within the time limits specified above, the Engineer will impose a daily monetary traffic control deficiency deduction for each calendar day (or portion thereof) the deficiency exists, as described in Article 105.03 of the Standard Specifications.

A traffic control deficiency deduction will be made for each individual component of the RTTCS that is not functioning correctly. Individual components of the RTTCS are traffic sensors, central base station unit, and warning signs with flashers.

Method of Measurement: This work will be measured for payment as follows.

Real-time traffic control warning sign will be measured on a calendar month basis per each unit, which each unit consists of one warning sign with two amber LED flashing lights attached and remote communication hardware and software and controllers capable of communicating with other components of this system.
