Vehicle Detection at Intersections

Detection-Control System

TxDOT Report 5-4022-01-1: In-Service Evaluation of a Detection-Control System for High-speed Signalized Intersections. K. Zimmerman and J. Bonneson. This report documents the findings and conclusions reached as a result of a three-year implementation project. An evaluation of before-after data at five intersections equipped with the Detection-Control System indicated that it was able to reduce delay by 14 percent, red-light violations by 58 percent, and severe crash frequency by 39 percent.  REPORT

TxDOT Report 0-4022-2: Intelligent Detection-Control System for Rural Signalized Intersections. J. Bonneson, D. Middleton, K. Zimmerman, H. Charara, and M. Abbas. This report describes the development and evaluation of an intelligent detection-control system (D-CS) that will reduce the number of drivers running the red indication and improve intersection safety.  REPORT   


Video Detection Design and Layout

TxDOT Report 0-4285-3:  Intersection Video Detection Field Handbook. J. Bonneson and M. Abbas. This handbook is intended to assist engineers and technicians with the design, layout, and operation of a video detection system. It is a condensed version of the Intersection Video Detection Manual.  REPORT 

TxDOT Report 0-4285-2:  Intersection Video Detection Manual. J. Bonneson and M. Abbas. This manual assists engineers with the planning, design, and operation of a video detection system.  REPORT

TxDOT Report 0-4285-1:  Video Detection for Intersection and Interchange Control. J. Bonneson and M. Abbas. This research was conducted to gather information about video detection system planning, design, and operations and to develop guidelines that describe the “best” practices for Texas conditions. This report documents the findings from the information gathering and guideline development activities.  REPORT

  

Detection Design and Layout

Manual of Traffic Detector Design. J. Bonneson and P. McCoy. This manual provides a step-by-step procedure for designing and operating traffic detectors at signalized intersections. The manual includes several design variations that make it adaptable to the design preferences of the operating agency and the traffic requirements of each specific intersection. The manual also describes a methodology for evaluating the detector design in terms of its operational and safety performance.  MANUAL   SPREADSHEET

Report TRP-02-31-93: Traffic Detector Design and Evaluation Guidelines. J. Bonneson, P. McCoy, and B. Moen. The objective of this research was to develop traffic detection design and evaluation guidelines. The evaluation guidelines are can be used to quantify detection design performance in terms of phase max-out frequency and delay. The detection design for high-speed approaches considers the location of the dilemma zone. A model for predicting the location of this zone was developed using data describing driver probability of stopping in response to the yellow indication.  REPORT
