Overview
In this section explains a Jcast Vehicle Detection Sensor, the contents
of a Sensor Information and Sensor Specifications
On Road Sensor Node (ORSN) SC-100
A Jcast On Road Sensor Node (ORSN)
is a magnetometer capable of low-
power radio communications packaged
in a small, hardened plastic case
suitable for in-pavement mounting.
ORSN detect canges in the earth’s magnetic field to determine the
presence or absence of vehicles relative to the detection zone of the ORSN.
Detection “events” are transmitted via Wireless Communications to a Jcast
Road Side GateWay(RSGW) where they processed, stored and forwarded
to other systems(SUS).
ORSN utilizes multifunctional sensors which consist of three-axis AMR,
physical and pressure sensors listed in Tables I and II. The three-axis AMR
is used for vehicle detection, classification and speed measurement while
other sensors are used for calibration and enhancement of measurements.

Installation Procedures
This section discusses installation requirements and provides step-
by-step installation procedures.
Required Equipment
Before installing a ORSN, ensure that the following components are
available :
Jcast On Road Sensor Node(ORSN)(s)
A minimum of one tube of FJS epoxy for each ORSN
A 2:1 ratio pack of Fablck Joint Seal(FJS), a two-component 100% solid
silicone polyurea-based joint sealant is recommende. This self-leveling joint
sealant displays fast cure times and excellent adhesion to concrete. In
ambient temperatures from 20°F (-6.6°C) to 180°F (82.2°C) the epoxy
cures in approximately five minutes.
Coring bit suitable for creating a hole (4” diameter, 2 ¼” depth [10.2
cm, 5.7 cm]) in the target surface
Two types of 4-inch drill bits, each with 1¼” standard machine threaded
sleeves, are recommended as shown in the following diagram.
Jcast Vehicle Detection System SC-100 User Manual

Coring bits
For soft road surface, a 4” double cylinder coring bit is recommended.
Once a 2” (5cm) deep hole is drilled, chisel any remaining material so that
the result is a flat bottomed hole. For harder surfaces, a 4” grinding coring
bit is recommended.
Use a shop vacuum or other implement to ensure that the hole is free of all
dust, debris and loose impediments.
Coring drill and frame
Cold chisel and club hammer or a power chisel
A shop vacunm, brush of other implement suitable for removing
dust and debris from a hole cored in the oave ment
Heat gun propane torch (helpful in environments with significant
roadway moisture)

Step-by-Step Procedures
Installing the Sensor/Shell Assembly into the Pavement
1. Find and mark the center of the desired ORSN location.
2. Core a hole approximately 4”(10cm) in diameter, and 2¼” (6 cm) deep into
the pavement Check depth as your drill, remove debris periodically.
Coring Sensor Hole
3. Vacuum or brush the hole clear of dust and debris
Clearing Sensor Hole
Ensure that the hole is dry as moisture may impede the curing of the epoxy.
If moisture is observed, use the heat-gun or torch to dry the inside of the
hole completely.

4. Apply epoxy to the bottom of the hole to a depth approximately 1/3 of the
hole’s total depth.
First Epoxy Application
5. Place Sensor in hole. Verify the following

Arrow on label points in the direction of traffic flow
6. Fille the hole with epoxy, empletely covering the ORSN
