2025 FEDERAL OVERLAY, W MUKILTEO BLVD – GLENWOOD AVE TO DOGWOOD DR <br /> PAGE SP108 OF SP123 SPECIAL PROVISIONS <br />WORK ORDER #3842 April 15, 2025 FEDERAL AID# NHPP-2776(011) <br /> 1 <br />Video System Communications Module 2 <br /> 3 <br />The Communication board shall be integrated with the TI BPL2 EDGE card 4 <br />and fit directly into NEMA TS1 & TS2 type racks as well as Type 170/2070 5 <br />input files. 6 <br /> 7 <br />9-29.18(3)B Functional Capabilities 8 <br /> 9 <br />Real Time Detection of vehicles and bicycles using the roadway. Bicycles 10 <br />using the roadway can be detected regardless of which lane they are using 11 <br />even if vehicle traffic is present. Bicycles detected can have a separate output 12 <br />to allow bikes a pre-call or a longer minimum green. 13 <br /> 14 <br />The TI BPL2 EDGE system shall be expandable up to 8 FLIR sensors that 15 <br />may be programmed independently. Up to four (4) TI BPL2 EDGE cards may 16 <br />be used if more than 8 sensors are necessary – up to 32 FLIR sensors. 17 <br /> 18 <br />The system shall be capable of displaying detection zones on the thermal 19 <br />image with associated outputs. Outputs/Inputs status will be indicated on the 20 <br />screen. Parameters will also include the ability to view raw video without any 21 <br />verbiage and/or detectors for surveillance purposes. Signal phasing can also 22 <br />be displayed in a NEMA TS2-1 cabinet with an accompanied PIM Module and 23 <br />SDLC interface (optional). 24 <br /> 25 <br /> 26 <br />Each thermal traffic detector will detect within its view the presence of 27 <br />vehicles or bicycles in user defined zones. Detectors available shall be 28 <br />presence, count, delay, extension, or pulse mode for either arrival or 29 <br />departure of vehicles. Delay and extension shall be defined between 0.1 – 30 <br />99.9 seconds and pulse mode between 0 – 200ms in 33ms increments if 31 <br />NTSC is used. Each thermal traffic sensor shall also detect and collect traffic 32 <br />data of passing vehicles in user-defined zones. 33 <br /> 34 <br />Collected traffic data by direction shall include: 35 <br /> 36 <br />· Volume (absolute numbers) per length class and per lane. 37 <br />· Average speed (km/h or mph) per length class and per lane. 38 <br />· Average gap time (1/10 sec) per length class and per lane. 39 <br />· Average headway (m or feet) per lane. 40 <br />· Occupancy (%) per lane 41 <br />· Confidence (0-10) depending on Thermal Quality of Image 42 <br />· Density (Vehicles / KM) Number of Vehicles over distance 43 <br /> 44 <br />Once an IP address is set up the thermal traffic detector shall be programmed 45 <br />with the use of a computer or network connection. A standard computer 46 <br />running a web browser is necessary. 47
