 Computer
Aided Dispatch System
 he
Computer Aided Dispatch (CAD) is the system of processing telephone
calls from the public and the dispatches to police vehicles.
The CAD computer system is has a completely redundant back-up
protocol to ensure 99% reliability. It is the most sophisticated
computer-operated dispatching system of any large police department
in the nation.
Computer Aided Dispatch is a computerized version of our old
complaint dispatch system.
How It Works
Dispatchers receive calls from the public via 9-1-1. The information
received is entered into a computer terminal that has been programmed
to process these calls.
The operation of the CAD system can be simplified into the
following steps:
| 1. |
A call for service is received
by a call-taker. |
| 2. |
The call-taker enters the
required information into a terminal, guided by a pre formatted
screen. |
| 3. |
The computer accepts the
assignment information; checks the validity of the address
using the Geographical Base File (G.B.F.), dispatches it
to the correct broadcasting console then nominates available
units (car, wagon, foot beats, etc.) to handle the assignment:
|
| 4. |
Each dispatch is given a
priority rating according to the nature of the assignment
The dispatchers' list of assignments is continually . updated
according to priority. |
| 5. |
Police vehicles receiving
assignments are required to notify Radio when they arrive
at the location of the assignment. |
| 6. |
The computer automatically
generates District Control (D.C.) numbers for all assignments
requiring them as denoted by the nature of the assignment.
District Control Numbers are the Philadelphia Police Department
equivilent to case or incident numbers. |
| 7. |
Provisions are incorporated
into the system to provide for "on-site" incidents and "walk-in"
complaints. |
| 8. |
The computer automatically
maintains a status board for each District:; listing all
vehicles working on a specific tour, their status and current
assignment: This is a feature available to all Commanders
via their Operations Desk terminal. |
| 9. |
The computer generates reports
relative to police complaints, dispatches and patrol vehicle
activity. |
