Study of UML Architecture for Designing Advanced Accident Information System

Increasing Private and public vehicles have caused the increasing rate of accidents. In that case, an up to date and effective use case and class diagram will play a very important role to enhance accident or traffic related information management system to acquire or achieve requirements of traffic level reduction, travel time prediction, and shortest path analysis. A centralized information system can provide the solutions to all queries related to traffic, route and obstruction analysis via retrieving updated information, regular monitoring and controlling traffic from a centralized system. In order to develop that centralized information system for traffic and road accidents, UML (Unified Markup Language) has been proposed in this article to understand pre and post accident information via use case and class diagrams. These diagrams have provided all information related to road, weather conditions or many other factors for pre and post accident analysis. With the help of these diagrams, a multipurpose accident information system can develop over the web to provide all road accident information before accident and resource allocation after the accident.

This is the enhancement in UML diagram of earlier accident related information system by adding more attributes or facilities of emergency response system. So, it is termed as UML diagram for advanced accident information system. Pre-accident analysis includes traffic, obstacle, shortest route analysis etc. and post-accident analysis includes emergency response i.e. ambulance and other services. A use case diagram and class diagram into different forms has been proposed to achieve an effective design of advanced accident information system. A use case diagram on the basis of attributes has been designed to achieve to get all information for best route selection in case of traffic or obstacle with all safety and emergency response factors. Class diagrams have been divided into different categories i.e. an overview of advanced accident information system, accident identification, accident location with vehicles & victims details, and classification of a total number of accidents according to different types. These class diagrams have been designed on the basis of attributes of entities and operations based on the object-oriented methodology. Component and attribute based designs help to reduce complexity or increase modularity.  Effective and understandable design for advanced accident information system enables the passengers and vehicle owner to choose their route with minimum travel time. It is also very beneficial in planning phase where database requirements need to understand and analysis phase after developing an effective advanced accident information system. It also fulfils all safety or security related information. Requirement, implementation, testing and verification phase are the part of planning phase which depends on these designs. It will prove very effective or beneficial for future accident related information system and emergency response system. So, a use case diagram with different forms of class diagrams has been proposed using attributes, entities, and operations for advanced road accident information with safety or emergency response factors with the help of IRC (Indian Roads Congress).
