The patrol allocation model presented is based on previous research. Data collection and data analysis are used to determine the most efficient patrol assignments. Data should include calls- for-service and officer-initiated incidents, as well as the time and location of police activity. Data analysis involves the calculation of time spent completing various types of calls-for- service and officer-initiated incidents. Other factors that should be considered when developing a patrol allocation model include features of the district, type of patrol technique used, political influence, time needed to respond to an incident, and the number of available officers. In the Texas survey on patrol allocation, 40 agencies responded, with 23 agencies reporting the existence of a patrol allocation plan. The responding agencies viewed patrol allocation as a responsibility of the operational support unit. The proportion of officers to citizens was higher in those agencies that implemented an allocation plan compared to those agencies that did not have a plan. Fifteen of the 23 agencies that had patrol allocation plans had computer programs to assist in the determination of patrol personnel allocation. Five agencies reported that their patrol scheduling conformed to the patrol allocation plan precisely, and 11 agencies indicated that their scheduling varied slightly from the plan. Seventeen of the 23 agencies with a plan used calls-for-service as a factor in determining their plan. Officer-initiated incidents were used by 13 of the agencies. Eighteen agencies reported that they reviewed their plans every 6 months to 1 year. 3 tables, 4 figures, and 9 references
