Improved Dual Loop Derived Truck and Speed Data

Obtaining proper, real-time truck vehicle classification and speed data from the current dual-loop system is currently a problem. This research will identify loops in need of adjustment, determine necessary adjustments and develop a field manual for maintaining the dual-loop system. The result will be improved truck classification and speed data from the dual loop system.
