ASTM International Standard Specification for Highway Traffic Monitoring Devices ASTM E2300-06

This specification describes the recommended procedure for identifying the performance and operating requirements to be included in a purchase order for Traffic Monitoring Devices. The traffic monitoring device shall be classified according to the functions they perform, the data they provide, the required accuracy of the data, and the conditions under which the device is expected to operate in conformity with the requirements. Acceptance tests are divided into two categories: Type-approval Test and On-site Verification Test. The accuracy required of a TMD for data acquisition and characterization of vehicles and traffic flow parameters is related to the traffic management or data reporting task supported by the device.
