THE PROBLEM OF ALLOCATING POLICE CALLED-FOR-SERVICE UNITS TO POLICE DISTRICTS IS CONSIDERED.

Abstract

THE STUDY ATTEMPTS TO BRIDGE THE GAP BETWEEN THE STOCHASTIC CAR ALLOCATION MODELS WHICH CHARACTERIZE CALLS FOR SERVICE BY THEIR INTERARRIVAL AND SERVICE TIME DISTRIBUTIONS, AND THE HAZARD SCORE MODELS WHICH ALLOCATE CARS ON THE BASIS OF FACTORS SUCH AS CRIME RATE, ARRESTS, AND RATE OF CALLS FOR SERVICE. SIMPLE, OPERATIONALLY DEFINED MEASURES OF THE RATES OF INJURY, PROPERTY LOSS, AND FEAR PRODUCED BY EACH TYPE OF CALL, AND DATA ON THE MIX AND RATES OF CALL TYPES ARE USED TO COMPUTE A FOURCOMPONENT MEASURE OF SERVICE FOR EACH DISTRICT. 1967 DATA FOR ST. LOUIS ARE USED TO ILLUSTRATE THE COMPUTATIONS.
