The purpose of the Michigan Signal Optimization Guidelines is to provide guidelines and recommendations for conducting signal optimization projec ts in the state of Michigan in a complete and consistent manner. This document is intended to guide the process, and not to be a restrictive document.
Technical document on Signalized Intersection Delay Models
The purpose of this report is to identify the steps that are required to time traffic signals, and to identify areas that will result in improved traffic signal timing. These steps define a continuing process that may be manual, semi-automated, or fully automated. In the abstract, the
The conventional approach to signal timing op timization and field deployment requires current traffic flow data, experience with optimization models, familiarity with the signal controller hardware, and knowledge of field operations including signal timing fine-tuning. Developing new signal timi
This is one of a series of documents providing support for deploying Intelligent Transportation Systems (ITS). This series addresses Traffic Signal Control Systems, Freeway and Incident Management Systems , Transit Management Systems, and Traveler Information Systems. The National ITS Architectur
Advance warning signals (AWS) provide information warning drivers in advance of the end-of-green interval for an approaching signali zed intersection. The purpose of this research was to develop guidelines for the placement of AWS in Utah, both c onditions to evaluate the need for AWS installatio
A driver approaching a signalized intersection where the light has turned yellow must make a decision whether to stop or proceed. A signal that is proper ly designed will provide an opportunity for a safe and legal maneuver. As approach speeds increase, how ever, it becomes more difficult to exec
Advance warning signals installed upstream of a high-speed signalized intersection (HSSI) warn motorists of impending signal changes in an effort to reduce the frequency of red-light running (RLR) and crashes. A new advance warning signal design was tested on an approach to a HSSI in Salt Lake Co
