1.23 BICYCLE DETECTION SYSTEM <br /> A. Bicycle Detection System equipment and installation shall comply with the applicable <br /> provisions in Section 16500 of the City's Engineering Standards, Section 86 of the State <br /> Standard Specifications, and any applicable State Standard Plans. <br /> B. Detection system shall be cable of providing reliable and accurate presence detection <br /> and countirig detection for both motor vehicles and bicycles. <br /> C. Detection system shall consist of TrafiSense bicycle sensors by Flir Intelligent <br /> Transportation Systems, or an approved equal. <br /> D. General Description: <br /> 1. The dete�tion system must be non-intrusive and shall consist of a traffic sensor and <br /> a video detection module with video detection software. <br /> 2. The traffic sensor and video detection module must be integrated in one housing <br /> without the need for any additional video detection software outside of this housing. <br /> By using one or more predefined detection zones, the video detection software will <br /> have the ability to detect vehicles and bicycles on multiple lanes. Bicycle detection <br /> zones will be separate from vehide detection zones. <br /> 3. The video detection software will have the ability to differentiate between vehicles <br /> and bicycles with a high level of accuracy and allow for separate outputs to be used <br /> for vehicle presence and bicycle presence. <br /> 4. The detection system shall generate separate vehicle and bicycle presence events <br /> and counting data. The generated vehicle and bicycle presence events will be sent <br /> to a traffic signal controller. <br /> 5. The operator shall be able to view the streaming video images of the detection <br /> system using a web browser. <br /> E. Hardware: <br /> 1. The detector bracket shall allow horizontal and vertical mounting and shall be <br /> lightweight. Stainless steel bolts and bands shall be used to attach the housing. <br /> 2. The housing of the camera and detection module should be compact and have an <br /> integrated rain/sun shield. <br /> 3. A red detection LED, clearly visible from the ground, allows both the vehicle drivers <br /> and maintenanoe personnel to see the status of the video detection module (i.e. <br /> detection, boot mode, safe status). <br /> 4. The traffic sensor shall not depend on any visible or invisible(infrared) illumination or <br /> image intensifier to "see" i.e. produce images. The traffic sensor shall be totally <br /> passive and not produce any energy or emit light in any bandwidth. The thermal <br /> traffic sensor shall allow the user to clearly identify images in the total absence of <br /> light. <br /> 5. The traffic sensor shall improve user visibility through smoke and dust compared with <br /> CCTV cameras. <br /> 6. The traffic sensor shall utilize a Vanadium Oxide (VOx) uncooled microbolometer <br /> responding in the LWIR(Long Wave Infrared)spectral range of 7.5— 13.5 �am. <br /> SPECIAL CONDITIONS 00800-6 <br /> BREWSTERAVENUE/BROADWAY BICYCLE DETECTION PROJECT <br />
