Ensure axle sensors are installed in the roadway and secured using an adhesive bonding material listed on the APL. Install axle sensors in the right -hand wheel -path midwa y between the leading and trailing loops as detailed in Standard Plans, Index 695-001. Install axles sensors in the left-hand wheel -path when no paved shoulder exists and sensor lead exit windows are installed at the right -hand edge of the roadway surface or in a lane which is to the left of and adjacent to an open lane of traffic. Install the axle sensor such that the cable end is closest to the pull box to which the sensor lead cable will be routed. Install the end of the sensor mid -way into the edge line stripe or lane line stripe. Ensure that the axle sensor being installed has lead -in cables of sufficient length to reach the cabinet without splicing. Do not splice axle sensor lead -in cables. Route the sensor lead to the pull box then to the TMS c abinet. Mark the sensor lead at the pull box and at termination in the cabinet. Submit lane numbering information as specified in Standard Plans, Index 695-001. Allow newly applied asphalt to cure for a minimum of 30 days prior to the installation of in -road sensors. Use a chalk line or string and paint to layout the position of the sensor and lead -in cable slots. Ensure saw cuts do not deviate more than 0.5 inches from the chalk line. Use a single blade or ganged blade saw wide enough to cut the axle sensor slot at full width in a single pass. Cutting two slots and chipping out roadway material between them is not allowed. Cut the slot the length of the sensor plus an additional 3 to 4 inches. Ensure the depth and width of the slot is installed as recommended by the sensor manufacturer, typically 0.75 inches wide by 1.5 to 2 inches deep. Use clips or jigs provided by the manufacturer to suspend the sensor at a uniform depth in the slot. Mix and apply the bonding agent ensuring the slot is complet ely full with no voids beneath the sensor. 695-3.2.2 Test Requirements: Perform the manufacturer’s recommended on -site pre-installation test to determine the sensor’s condition using an Inductive Capacitance Resistance meter. Install only those sensors that pass the pre -installation test. Record all test results by lane on the warranty form provided by the manufacturer and leave a copy in the cabinet. Repeat the test at the termination point in the cabinet after installation.

Fasten the cable to the pole so wind does not move it, or route the cable within the pole cavity to the cabinet termination point. Provide 18 to 24 inches of s lack in the cable at the connections to the sensor and in the cabinet to ensure the cable is stress -free. Include the appropriate mounting hardware, contact closure signal that corresponds to vehicle presence and the manufacturer’s recommended surge suppre ssion as a part of the installation. Set up the lane detection zones using the manufacturer’s instructions and software and verify that the sensor’s orientation is perpendicular to the roadway. Configure the wireless vehicle sensor for vehicle volume unless otherwise specified in the Plans. 695-3.3.3 Test Requirements: Conduct a visual test to determine that all detection zones are being counted accurately. Connect a personal computer (PC) to the electronics unit and observe traffic in every lane , verifying that each vehicle is displayed on -screen. A minimum of 20 vehicles should be observed for each lane of traffic with all vehicles counted; assuming a clear line of sight between the sensor and the vehicle being observed is maintained. If any vehicles are not counted, reconfigure the wireless vehicle sensor and repeat the visual observation test until all lanes count correctly. If the sensor fails to provide accurate counts after three test attempts, it must be replaced with a new unit at no ex pense to the Department. Provide a time synchronized video of testing, if requested. Submit a 48 hour verification (class, speed and volume) report for all TMS to the Engineer.
