    The effect of the conventional method of patrolling on crime is highly contested by the research evidence, no matter of the intensity of such patrols. The conventional method lies on routine randomized patrol in an area, which has held that it deters crime by maintaining a visible presence based on the assumption of deterrence. The overall aim of this research is to discover the effect of increased car patrols in a region on crime reduction. The paper reviews research on patrol effectiveness in reducing crime, in the context of patrolling methods, tactics and practices. Additionally the study attempted to infer the impact of increased car patrols on crime rates with the analysis of crime statistics concerning two study periods. Finally, the author estimates patrol effectiveness in reducing crime on the basis of red-handed arrests during patrol task.
    This research finds that there is a growing body of evidence to support the view that patrols are effective on crime reduction only when they are problem oriented, tailored and geographically focused on hot spots; a new patrol strategy approach that has been called evidence-based policing. Randomized preventing patrol practices of “one-size-fits-all” are considered to be insufficient on reducing crime rates, regardless of the quantitative size of such patrols. On the other hand, the analysis of crime statistics failed to draw valid conclusions due to two major factors; the first was the possible existence of the "dark figure" of crime, since crime statistics constitute only recorded crime, and the second lies in the contestable amount of police patrols delivered in each of the experimental periods. In contrast, primary research of this study accomplished the strong conclusion that the hot spots method of patrolling is more effective and efficient on red-handed arrests and that patrol strategies that focus on specific types of crime in specific locations yields the most effect on those specific crimes.
