A Conceptual Approach for Using UCF Driving Simulator as a Test Bed for High Risk Locations

The main objective of this paper is to illustrate the use of the University of Central Florida’s (UCF) Driving Simulator as a test bed for high-risk locations such as signalized intersections and toll plazas. The Alafaya (SR434) – Colonial (SR50) signalized intersections in Orange County, Florida, is used to validate the simulator. The SR434 – SR 50 intersections is a four-leg 6x5 signalized intersection, and has two left turn lanes and one tight turn lane for every approach. Both safety and traffic measures are being used in the effort to validate the simulator and therefore prove its usability as a test bed. Safety will involve identifying the potential safety problems from cash reports, and the authors will observe whether subjects will face the problems in the simulator, thus validating it. Multiple scenarios are being developed covering the different safety problems and approaches to the intersections. Using the Florida Department of Transportation Crash Analysis Reporting (CAR) System, the crash reports at this intersections for the years 1999 to 2002 were obtained and analyzed. Of the 164 crashes that happened during the four years at the intersection, 95 have been rear end. It has been found that most of the rear-end crashes took place in the right turn lanes of SR 434. The new approach here is the use of crash history to identify the high risk locations and type of collisions at the intersection, and then observe the “near misses” in the simulation. If both coincide, this could be one of the validation criteria that could be used. A between-subjects 3X2 (3 age groups and 2 genders) factorial experimental design has been modeled. Sixty subjects will drive the simulator, running through 11 scenarios, mainly the right turn lanes on SR 434 in both the directions, when the signal is green/red/amber for traffic on SR50 (for traffic conflict validation), the through lanes of SR434 when the signal is green (for speed validation), and the through lane on SR50 when the phasing changes from green to amber. Measurements of speed, deceleration rate, the position of stop and the steering performance, will be collected. The paper will also assess the effect of gender and age.
