OVERLAND PARK IS A CITY OF 82,000 INHABITANTS IN A 48 SQUARE MILE AREA. TECHNICAL ASSISTANCE WAS REQUESTED DUE TO INCREASED CRIME AND POPULATION IN THE CITY; POOR SIGNAL AREAS IN THE NORTH AND SOUTH SECTIONS CAUSING FAILURE OF MOBILE AND PORTABLE PATROL OFFICER COMMUNICATIONS WITH THE DISPATCHING OFFICE; AND THE NEED FOR GREATER COMPUTER STORAGE AND FASTER RETRIEVAL PROCESSES. ON-SITE EVALUATION WAS CONDUCTED BETWEEN JULY 12, 1976 AND JULY 15, 1976. IT INCLUDED ASSESSING PRESENT COMMUNICATIONS CONTROL CENTER ACTIVITIES; EXAMINING SYSTEM OVERLOADS, INTERFERENCE, AND FAILURES; REVIEWING OPERATING TECHNIQUES; ASSESSING ADEQUACY OF PRESENT FACILITIES AND EQUIPMENT; EXAMINING EXPANSION POTENTIAL WITH PRESENT EQUIPMENT; AND DEVELOPING A FREQUENCY PLAN. FINDINGS INDICATE THAT UPDATED EQUIPMENT, PROCEDURES, AND INTERAGENCY COMMUNICATIONS ARE NEEDED AND THAT A COMPUTER AIDED DISPATCHING SYSTEM COULD EVENTUALLY CONNECT WITH THE ALERT (ALLIED LAW ENFORCEMENT RADIO TIE) SYSTEM IN KANSAS CITY TO RETRIEVE FEDERAL AND STATE FILE INFORMATION.
