A Microscopic Traffic Flow Model Characterization for Weather Conditions
Applied Sciences, 2022 Road surfaces are affected by rain, snow, and ice, which influence traffic flow. In this paper, a microscopic traffic flow model based on weather conditions is proposed. This model characterizes traffic based on the weather severity index.

A Microscopic Heterogeneous Traffic Flow Model Considering Distance Headway
Mathematics, 2022 The intelligent driver (ID) model characterizes traffic behavior with a constant acceleration exponent and does not follow traffic physics. This results in unrealistic traffic behavior. In this paper, a new microscopic heterogeneous traffic flow model is

From Heterogeneous Microscopic Traffic Flow Models to Macroscopic Models [PDF]
SIAM Journal on Mathematical Analysis, 2021 The goal of this paper is to derive rigorously macroscopic traffic flow models from microscopic models. More precisely, for the microscopic models, we consider follow-the-leader type models with different types of drivers and vehicles which are distributed randomly on the road.

Deterministic approach to microscopic three-phase traffic theory [PDF]
Journal of Physics A: Mathematical and General, 2005 Two different deterministic microscopic traffic flow models, which are in the context of the Kerner's there-phase traffic theory, are introduced. In an acceleration time delay model (ATD-model), different time delays in driver acceleration associated ...

Microscopic and macroscopic traffic flow models including random accidents [PDF]
Communications in Mathematical Sciences, 2021 We introduce microscopic and macroscopic stochastic traffic models including traffic accidents. The microscopic model is based on a Follow-the-Leader approach whereas the macroscopic model is described by a scalar conservation law with space dependent flux function. Accidents are introduced as interruptions of a deterministic evolution and are directly

Enhancing traffic safety analysis with digital twin technology: integrating vehicle dynamics and environmental factors into microscopic traffic simulation. [PDF]
Sci RepTraffic safety is a critical concern in transportation engineering and urban planning. Traditional traffic safety analysis requires trained observers to collect data in the field, which is time-consuming, labor-intensive, and sometimes inaccurate.
