Philippines Data Collection Project Description: IRD has supplied data collection equipment including counters, sensors, and data analysis software. The sensors for this project are class 2 BL type piezoelectric sensors, inductive loops, and road tube. Varying congurations of trac counters / classiers (TCCs) will collect volume and classication data to help the DPWH plan for future road usage. There are three (3) types of site congurations. These are: four lane (two direction) sites of Loop-Piezo-Loop (LPL), two lane (two direction) sites of LPL, and two lane (two direction) sites of Road Tube. The piezo sites are further divided into what are termed "permanent" and "portable" sites. The dierence between the two is that the permanent sites will have the counter collecting data for ex
