SECTION 6 – TRAFFIC AND LIGHTING <br />86 <br />6-3.8 DETECTION <br />Detection at signalized intersections shall be from thermal imaging sensors mounted on traffic signal <br />strain poles or mast arms capable of monitor traffic and bicycle activities in all weather conditions. <br />Preformed loops shall be used with concrete at locations that are unsuitable for thermal detection and loop <br />detectors with saw cuts should only be used at locations that are unsuitable for thermal detection and <br />preformed loops. Loop detector housings shall be installed outside of the travel lanes, in the shoulders, <br />or in the median if the lane is adjacent to one of these. Refer to Standard Drawing 6-6 to locate detector <br />housings on roadways with curbs and no shoulders. <br />Advanced detection may be required on all approaches with design speeds greater than thirty (30) mph, <br />unless specifically waived by Engineering. Each lane of an approach shall have its own detection channel <br />on the controller. Adjacent lanes of the same movement may not be configured as a single channel. <br />Multiple approach lanes must have individual lane by lane detection. <br />6-3.9 APPROVED EQUIPMENT <br />All signal components shall be NEMA TS-2 compliant with the following approved equipment used <br />unless otherwise approved by South Bend Bureau of Traffic and Lighting. <br />Signal cabinets: Econolite ‘P’, ‘M’, or ‘G’ Cabinets. <br />Controller: Econolite ASC/3-2100 with Ethernet port and Purdue Data Logging enabled <br />or Econolite Cobalt 2100 controller <br />Video Detection: FLIR thermal sensors processed by Autoscope RackVision Terra <br />Conflict Monitor: Reno A&E MMU2-1600GE <br />Loop Detectors: New construction, under pavement, Reno A&E PLH Preformed Loop <br />Replacement or Retrofit, saw cut installed, Reno A&E PLB Preformed Loop <br />In-Pavement Det.: TrafficWare POD Wireless Detection System <br />Loop Amplifier: Reno A&E Model C-1203 with counting enabled <br />Load Switches: Reno A&E LS-200 <br />Advance Detection: Loop or In-Pavement (see above). <br />Signal Heads: Econolite, polycarbonate, black aluminum backplates with reflective tape <br />Pedestrian Head: General Electric Model GT1 LED sixteen (16) inches by eighteen (18) <br />inches with countdown module Model PS7- CFF1-27A or Leotek TLS- <br />PED-16-CIL-P1 <br />Pedestrian Button: Campbell Company AAPS with cabinet located APC or Campbell Company <br />AGPS
