Peter Martin et al, Detector Technology Evaluation, November 2003

Summary: This paper reports on the present status of detector technologies and on development trends in these technologies. This report designs a systematic selection method suitable for permanent applications. The selection method considers factors including data type, data accuracy (in different environmental and traffic conditions), ease of installation and calibration, costs, reliability, and maintenance. A variety of detector technologies and devices are compared. This report provides comparison matrixes based on detector technology and specific devices in this field of technology. The technology matrixes offer general information about each detector technology. The device matrixes give specific information regarding each particular detector device. Selecting an appropriate device is more important than choosing a specific technology. The matrixes must be continuously updated to reflect changes in the detector market.
