AVL Equipped Vehicles as Probes - Phase 3
Record Type: DOT

Past phases of this research have demonstrated in the laboratory that it is possible to estimate travel speeds as well as construct travel times through corridors using existing transit vehicles equipped with automatic vehicle locators (AVL). These results could be used to augment the existing sensor network of loops, cameras and radar. This phase will incorporate these "virtual" sensors into the existing Transportation Management System real time database so they can be used by traffic management staff in the same way that loop data is used. The system will be updated to use global positioning systems (GPS).
