SPP Installation Considerations

This chapter provides the installation considerations for the SPP. Prior to 
installing the SPP, ensure that the following aspects have been considered in the 
site design.

Powering the SPP

 

Collecting Data From the APCC

Determining the Location of the SPP

Each consideration is discussed below. In addition, refer to the 

Sensys Networks 

Wireless Vehicle Detection System Reference Guide

, 

Design Guidelines for 

Freeway Applications

, and 

Design Guidelines for Intersection Applications

 for 

more information.

Powering the SPP

The overall network design determines how the SPP is powered; two general 
models are supported:

Acquiring power directly from a traffic controller cabinet

Acquiring power from a traffic controller using optional isolator 

Acquiring Power From a Traffic Controller

An SPP can be directly interfaced to a traffic signal controller through an APCC. 
When this is the case, power to the SPP is drawn from the traffic controller as 
shown in the following figure.
