An update on the Huntington beach automatic vehicle location system

An Automatic Vehicle Location (AVL) system has been installed in Huntington Beach, California, since 1977. This system is part of an integrated Computer Aided Dispatch/AVL system in use by the Huntington Beach Police Department. Since the initial installation, major changes and improvements have been made to the communications and location subsystems and the CAD/AVL computer interface as a result of operational evaluation over the past three years. These changes and improvements and a description of the capability of the AVL system operating in conjunction with the CAD system are described.
