Traffic Signal Operations Guidelines

TxDOT Report 0-6402-P1: Traffic Signal Operations Handbook, Second Edition.  J. Bonneson, S. Sunkari, M. Pratt, and P. Songchitruksa. This handbook provides guidelines for timing traffic control signals at intersections that operate in isolation or as part of a coordinated signal system. The guidelines are intended to describe best practices, as identified through interviews with TxDOT engineers and technicians, and to identify conditions where alternative practices are equally workable.  The handbook is intended to make resource investment in signal timing maintenance cost-effective and signal operation more consistent on an area-wide basis.  REPORT   SPREADSHEET  A User's Manual for the spreadsheet is included in the appendix of Report 0-5629-1.

TxDOT Report 0-6402-1: Development of Guidelines for Pedestrian Safety Treatments at Signalized Intersections.  J. Bonneson, M. Pratt, and P. Songchitruksa.  This report summarizes the research conducted and conclusions reached during the develop of guidelines for pedestrian safety treatments at signalized intersections. The guidelines are focused on treatments that alleviate conflicts between left-turning vehicles and pedestrians.  REPORT  

TxDOT Report 0-5629-1: Development of a Traffic Signal Operations Handbook.  J. Bonneson, M. Pratt, and K. Zimmerman.  This document summarizes the research conducted during the development of a Traffic Signal Operations Handbook.  The research conducted included a review of the literature, a survey of TxDOT engineers, and an evaluation of alternative signal controller settings and detection designs.  A spreadsheet was developed to automate several tasks involved in the development of a signal timing plan.  A User's Manual for the spreadsheet is included in the appendix.  REPORT
