When you call the police, the police dispatcher has to locate the car nearest you that is free to respond. This means the dispatcher has to keep track of the status and location of every police car — not an easy task for a large department.
Another problem, which arises when cars are assigned to regular patrols, is that the patrols may be too regular. If criminals find out that police cars will pass a particular location at regular intervals, they simply plan their crimes for times when no patrol is expected. Therefore, patrol cars should pass by any particular location at random times; the fact that a car just passed should be no guarantee that another one is not just around the corner. Yet simply ordering the officers to patrol at random would lead to chaos.
A computer dispatching system can solve both these problems. The computer has no trouble keeping track of the status and location of each car. With this information, it can determine instantly which car should respond to an incoming call. And with the aid of a pseudorandom number generator, the computer can assign routine patrols so that criminals can’t predict just when a police car will pass through a particular area.
( Before computers, police sometimes used roulette wheels and similar devices to make random assignments.)
Computers also can relieve police officers from constantly having to report their status. The police car would contain a special automatic radio transmitter and receiver. The officer would set a dial on this unit indicating the current status of the car — patrolling, directing traffic, chasing a speeder, answering a call, out to lunch, and so on. When necessary, the computer at headquarters could poll the car for its status. The voice radio channels would not be clogged with cars constantly reporting what they were doing. A computer in the car automatically could determine the location of the car, perhaps using the LORAN method. The location of the car also would be sent automatically to the headquarters computer.
The best title for this passage should be_________.
