|Project Name:||Calibration of Driver Behavior Parameters for Optimization of Work Zone Throughput|
Office of Operations Research and Development |
|Team:||Trans Ops Concepts and Analysis Team|
|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.|

|End Date:||November 1, 2013|
(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.
|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.|
|Fieldtest:||There will be two field tests: Instrumented Vehicle and Driving Simulator.|
|Expected Benefits:||Modeling and simulation of work zones.|
|Deliverables:||Name: Report with parameters for modeling work zone driver behavior.|
Product Type(s): Research report, Conference displays, Technical report, Article, Data
Description: The report will include the various thresholds to the Wiedemann Psycho-Physical model to model driver behavior accurately in work zones.
