Department Recommendation:
Staff recommends City Council authorize the City Manager to:
1. Enter into a contract with Don Berry Construction to furnish and install a video detection system at the intersection of Plaza Drive and Riggin Avenue for a not to exceed amount of $75,000;
2. Appropriate $75,000 from the Measure R Local Fund (Fund 131) for the new video detection at Plaza and Riggin;
3. Appropriate $55,000 from the General Fund (Fund 001) to purchase video detection equipment. $21,929 will be used to replace and install damaged video detection equipment at the intersection of Akers Street and Riggin Avenue caused by an accident and $33,071 will be used to purchase a spare video detection system for future use in the event another traffic signal location needs immediate replacement due to damage or failing video detection equipment.
Summary:
Staff is seeking to replace the in-pavement vehicle detection system at the intersection of Plaza Drive and Riggin Avenue with a video detection system. The in-pavement detection system has maintenance issues due to the large amount of truck traffic at this intersection. In-pavement detection is not designed to handle large volumes of heavy truck traffic which causes the pavement to rut resulting in malfunctioning detection equipment. This will be a capital improvement project to improve the intersection.
Staff is also seeking to replace damaged video detection equipment at the intersection of Akers Street and Riggin Avenue which was damaged by an automobile accident recently. The traffic signal cabinet (minus the detection equipment) was replaced following the automobile accident to make the traffic signal operational. However, the replacement traffic signal cabinet was not equipped with the auxiliary video detection equipment necessary for the operation of the video detection system. It is anticipated the replacement equipment will be installed within six weeks after the equipment is received. The City will be pursuing a cost recovery for the repair of the damaged traffic signal equipment through the City’s subrogation process. Furthermore, the City did not possess spare equipment like the traffic signal cabinet and controller.
The video detection system is used to identify the presence of vehicles as they approach an intersection or vehicles that are waiting at an intersection. The detection of vehicle provides the necessary information to the traffic signal controller which then allots the predesignated time based on the volume of traffic detected in any of the intersection approaches. This makes for a reactive intersection based on the traffic volume demands and therefore provides for a more efficiently operating traffic signal. The video detection system is not utilized for enforcement of red light runners, but strictly to determine the presence of vehicles which is used for the operation of the traffic signal.
And lastly, Staff also is seeking to purchase a spare video detection system for future replacement of any damaged or failing video detection system at any one of the City’s 46 signalized intersections utilizing this specific video detection system.
Background Discussion:
Plaza Drive at Riggin Avenue
The existing in-pavement vehicle detection equipment has failed due to the degradation of the roadway pavement caused by the truck traffic. A video detection system will provide for greater flexibility to detect vehicles, allow for future pavement repair without the need to install or reinstall in-pavement vehicle detectors, and provide for a more vehicle responsive traffic signal.
The replacement of the existing in-pavement vehicle detection system with the video detection system is consistent with the other video detection systems deployed throughout the City of Visalia. The City’s Traffic Safety maintenance staff is familiar with the Iteris video detection system which is currently deployed at 46 of the 132 existing signalized intersections throughout the city. Standardizing the video detection system provides for ease of maintenance and operations without having to maintain a supply of replacement components for multiple manufactures of video detection systems.
Don Berry Construction recently installed video detection systems at six intersections associated with the Pavement Rehabilitation of Walnut Avenue and Murray Avenue project. The contractor has agreed to extend the pricing for this additional intersection at the same unit price as the six completed intersections. Unit prices were competitively bid under the pavement rehabilitation project, therefore, staff recommends to attaching to this agreement which is an allowed procurement method. This method allows for the installation of the equipment several months sooner than if it was rebid.
Video Detection Equipment
The traffic signal cabinet at the intersection of Akers Street and Riggin Avenue was recently damaged due to an automobile accident. The accident required the replacement of the entire traffic signal cabinet which houses all the equipment necessary for the operation of the traffic signal. This replacement is requested to be funded by the General Fund. Traffic maintenance is funded in the General Fund and is responsible for all traffic signal maintenance.
The damaged traffic signal cabinet was replaced with a spare traffic signal cabinet provided by the City’s Public Works Department in the days following the automobile accident. However, the replacement traffic signal cabinet did not have all the auxiliary equipment needed to support the existing video detection equipment at this intersection. The purchasing and installation of the damaged components is needed to replace the damaged auxiliary equipment and for the operation of the existing video detection cameras.
The costs incurred for the repair and replacement of the damaged traffic signal equipment is part of the cost recovery through the City’s subrogation process from the accident that caused the damage. A list of the video detection components associated with the repairs is listed in Attachment 2. The City has a contract with a local electrical construction company to supplement the City’s traffic signal maintenance personnel make emergency repairs to existing signalized intersections and streetlights in order to minimize the impacts to the traffic flow.
The procurement of a complete video detection system, see Attachment 3, will be placed ‘on the shelf’ for future use. When utilized it will be to replace any damaged or failing video detection equipment currently at any of the City’s existing 46 signalized intersections currently operating with the Iteris video detection system. The procurement of a complete video detection system has had a lead time ranging between 12 weeks to 26 weeks. The spare equipment will allow for a quicker repair of failing equipment, minimize the impact to the motoring public, and allow for the traffic signal to operate in a more efficient manner. Standardizing the video detection system provides for ease of maintenance and operations without the need to maintenance a supply of replacement components for multiple manufactures of video detection systems.
