Dynamic Flashing Yellow Arrow (FYA) - A Study on Variable Left Turn Mode Operational and Safety Impacts - Phase II - Model Expansion and Testing

The objectives of this project are: (1) Expand the database and increase the number of intersections to 50 intersections. (2) Refine the decision support system (DSS) model and validate it using the expanded database. (3) Modify the coded version of the DSS model to reflect the results of the new database. (4) Virtual testing of the DSS through VISSIM API interface with the controller. (5) Field testing through a pilot study.
