Traffic state estimation (TSE) refers to the process of the inference of traffic state variables
(ie, flow, density, speed and other equivalent variables) on road segments using partially …

In recent years, artificial intelligence has gradually penetrated into various fields, and has
become a research hotspot. The modern industrial upgrades and transformation of the …

The fundamental diagram (FD), also known as the flow–density relation, is one of the most
fundamental concepts in the traffic flow theory. Conventionally, FDs are estimated by using …

Real-time and accurate traffic state identification can provide reference for urban traffic
control and guidance. Due to the randomness and complexity of traffic flow, it is difficult to …

Being one of the most classic concepts in the traffic flow theory, the fundamental diagram
(FD) describes the relationship between average flow and average density of link-level …

This work presents a methodology for measuring traffic quantities from crowd-sourced
trajectories for the purpose of estimating saturation flow rates. First, the observed trajectories …

Variable speed limit (VSL) systems are used to improve the traffic conditions by adjusting the
speed limits based on the current traffic situation. Advances in vehicle technology have …

The fundamental diagram (FD) describes the relation between the flow and density in
equilibrium conditions. In this paper, we propose an estimation approach to estimate the FD …

Sažetak A new statistical algorithm is proposed in this paper with the aim of estimating
fundamental diagram (FD) in actual traffic and dividing the traffic state. Traditional methods …

The fundamental diagram (FD) of traffic flow; a graphical description of the macroscopic
bivariate relationships between the three key traffic variables: flow, density and speed; is of …
