The key components of an Expert System for Traffic Accident Analysis include:

a) Rules set for analysis

b) AND/OR graph representation

c) Use of Working Memory and Production Rules

Designing an Expert System for Traffic Accident Analysis involves setting certain rules which the system will use to analyze the cause of an accident. These rules could include: If the road is wet and it is raining, then the accident may be due to slippery conditions. An 'AND/OR graph' represents these relationships showing the conjunction (AND) or disjunction (OR) of factors. For instance, a node could represent the accident ('A') and have two children nodes: 'Raining' (R) and 'Road Wet' (W). An edge 'A --> R' would mean the accident occurred while it was raining.

In the context of 'goal driven' method, the goal will be to determine the cause of the accident. The 'Working Memory' would begin with the facts of the occurrence, and the Production Rules utilize these facts to execute IF-THEN rules until the goal is reached.

In the 'data driven' method, the Working Memory starts with a problem's description and data, and the Production Rules are employed until a conclusion is reached. The search graph will show the sequencing of these rules.

To answer this question completely, it would be necessary to know the specific information kept in the Working Memory and the specific Production Rules. That's why you should refer to the expert system for the Car Diagnosis problem as an example.
