Design Guidelines for Deploying Closed Loop Systems
This manual discusses the many signals and signal systems owned and maintained
by the Indiana Department of Transportation (INDOT). These traffic systems are referred
to closed loop systems. The intent in preparing this manual is to reduce the time spent on
designing, employing, and maintaining signal controllers of the signal systems. With that
intent, the manual includes the best practices in current use as design examples. This
manual is also to serve as an informative tool to new IDNOT employees.
1. Chapter 1 – Introduction
This chapter gives a conceptual overview of what a closed loop system is
and how they are designed.
2. Chapter 2 – Closed Loop System Design Procedures
The objective of this chapter is to provide direction with the design of
controller timing parameters.
3. Chapter 3 – Configuring Econolite Closed Loop Traffic Signal Systems
Chapter 3 of the manual shows step-by-step how to configure Econolite
controllers to implement closed loop systems.
4. Chapter 4 – Configuring Peak Closed Loop Traffic Signal Systems
This chapter covers how to configure peak controllers to run a closed loop
system.
5. Chapter 5 – Hardware-in-the-loop Simulation For Testing Controllers
Chapter 5 discussed the necessary programs and procedures required to
run the traffic simulation.
6. Chapter 6 – Field Tuning Closed Loop Systems
This chapter discusses how to monitor and adjust the controller for the
closed loop system based on the system’s performance.
7. Chapter 7 – Conclusions
This chapter gives a brief overview of the chapters covered.
