PMSS Project Details

Project ID:	FHWA-PROJ-11-0025
Project Name:	Calibration of Driver Behavior Parameters for Optimization of Work Zone Throughput
Status:	Active
Contact:	Last Name: Lochrane First Name: Taylor Telephone: 202-493-3293 E-mail: taylor.lochrane@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Operations Research and Development
Team:	Trans Ops Concepts and Analysis Team
Roadmap/Focus area(s):	Not Applicable
Project Description:	The car-following and lane-changing driving behavior is different in work zones compared to normal conditions. The overall objective of this project is to calibrate work zone vehicle behavior in microsimulation to optimizing work zone throughput. This project will use an instrumented vehicle equipped with global positioning systems, speed sensors, cameras, vehicle CAN data, data acquisition systems, and Universal Medium Range Radar (UMRR) systems to measure the gaps and headway in real-time at 10 Hz with random participants.
Laboratories:	Human Factors Laboratory Saxton Transportation Operations Laboratory
Start Date:	April 1, 2011
End Date:	November 1, 2013
Funding Amount:	$0.00
FHWA Program Name:	Other
Goals:	(1) Evaluate the driver behavior and response while driving in work zones. (2) Collect real-time gap data for vehicles traveling in the work zone. (3) Examine the data with current psychophysical car-following equations. (4) Develop specific thresholds parameters with real-time data and the observed driving behavior to advance modeling and simulation of work zones.
Project Type:	Onsite
Background Information:	This study will involve many units within the United States Department of Transportation, Federal Highway Administration. Such offices include but are not limited to the Office of Traffic Operations, Office of Traffic Management, Office of Safety Research and Development, and Office of Operations Research and Development. The University of Central Florida, Civil Environmental and Construction Engineering Department, is also a partner in this project.
Test Methodology:	Questionnaire data and vehicle data will be collected from participants in the study to calibrate parameters in the car-following model.
Other Information:	Data not yet available
