Significance and Use
5.1 This practice addresses the installation of piezoelectric sensors that support traffic recording devices which are used for monitoring highway traffic characteristics. Thus, this practice provides information that must be used with professional judgment by qualified persons within governmental agencies and private firms to aid in the management of roads and roadway traffic.
5.2 Traffic monitoring is important to the safe and efficient movement of people and goods. The purpose of this practice is to ensure that traffic monitoring procedures produce traffic data and summary statistics that are adequate to satisfy diverse and critical traffic information needs.
1.1 This practice covers the installation of piezoelectric tire-force sensors that are used to detect axles when counting, classifying, or weighing vehicles as part of a roadway traffic monitoring program. Piezoelectric sensors are often used in pairs and combined with other roadway sensors such as inductive loops to classify and weigh vehicles.
1.2 The practice applies only to piezoelectric tire-force sensors used for the detection of vehicle axles on a roadway.
1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only and are not considered standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
