Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
Example of the slip angle curve obtained from a Pacejka Magic Formula empirical tire model. In vehicle dynamics, a tire model is a type of multibody simulation used to simulate the behavior of tires. In current vehicle simulator models, the tire model is the weakest and most difficult part to simulate. [1] [2]
Modeling and simulation (M&S) is the use of models (e.g., physical, mathematical, behavioral, or logical representation of a system, entity, phenomenon, or process) as a basis for simulations to develop data utilized for managerial or technical decision making.
MSC ADAMS (Automated Dynamic Analysis of Mechanical Systems) is a multibody dynamics simulation software system. It is currently owned by MSC Software Corporation. The simulation software solver runs mainly on Fortran and more recently C++ as well. [1] According to the publisher, Adams is the most widely used multibody dynamics simulation ...

To understand simulation, it is important to understand the concept of system state, which is a set of variables that contains enough information to describe the evolution of the system over time. [3] System state can be either discrete or continuous. Traffic simulation models are classified according to discrete and continuous time, state, and ...
The basic traffic model ruling the movement of vehicles was developed by Rainer Wiedemann in 1974 at Karlsruhe University. [3] It is a car-following model that considers physical and psychological aspects of the drivers. The model underlying pedestrian dynamics is the Social Force Model by Dirk Helbing et al. from 1995.

Microscopic traffic flow models are a class of scientific models of vehicular traffic dynamics. In contrast, to macroscopic models, microscopic traffic flow models simulate single vehicle-driver units, so the dynamic variables of the models represent microscopic properties like the position and velocity of single vehicles.
