1) Record-based Data Models When the database is organized in some fixed format of records of several than the model is called record-based data model. A fixed number of fields, or attributes in each record type
A database management system that stores and arranges data in a hierarchical structure is known as a hierarchical database management system (HDBMS). The data organization in this structure resembles a tree; parent-child relationships are used to store the data. Each parent node in a hierarchical...

In the first step of the CPIC framework, the detailed evasive driver behavior models (E-DBMs) in the form of probability density functions (PDFs) were introduced to generate more realistic collision-avoidance trajectories. Two techniques for sampling these trajectories, namely the Markov Chain Monte...
