Research
Interests
The main focus of the STAR Lab research
includes advanced traffic detection technologies and their
applications for safer and more effective traffic operations.
Specifically, we have the following research interests:
 Advanced Traffic Management Systems (ATMS)
- Dynamic estimation of freeway traffic speed
- Large truck volume estimation
- Congestion monitoring and forecast
- Dual-loop error identification and remedy
Advanced Traveler Information Systems (ATIS)
Real-Time Data Collection Systems
- High-frequency loop event data collection systems
- Portable loop data collection and system tune-up systems
- Traffic data collection using surveillance video cameras
- Video-Based Monitoring of Pedestrian Movements at
Signalized Intersections
[Demo (13 MB)] [Demo-
thermal (156MB)]
Smart Signal Control and Vehicle Routing
- Transit Signal Priorities (TSP)
- LOOP detector SIMulator (LOOPSIM)
- Adaptive signal control
- Vehicle routing
- GPS-based vehicle tracking and data collection
- Dilemma zone protection
Transportation Data Management and Analysis
- Transportation database design
- Transportation data visualization using Geographic
Information Systems (GIS)
- Traffic accident modeling
- Transportation asset management using GIS
- Traffic pollution estimation and impacts analysis
