MICROSCOPIC TRAFFIC FLOW MODEL WITH INFLUENCE OF PASSENGER TRANSPORT [PDF]

, 2023
To analyze the influence of passenger transport on traffic flow, we develop a microscopic traffic flow model that incorporates various factors such as vehicle speed, acceleration, deceleration, lane-changing behavior, and interaction between different ...

Microscopic and macroscopic flow models of traffic management

2022-yil, 3-son (133/1) ANIQ FANLAR SERIYASI, 2023
Today, the issue of video data processing is very urgent. For example, determining the purpose of human behavior, analyzing economic networks, identifying and eliminating traffic jams on the streets, etc. Nowadays, the increase in the number of vehicles moving on the roads creates traffic jams on the city streets.

Autonomous Vehicle Decision and Control through Reinforcement Learning with Traffic Flow Randomization

Machines
Most of the current studies on autonomous vehicle decision-making and control based on reinforcement learning are conducted in simulated environments. The training and testing of these studies are carried out under the condition of rule-based microscopic

Fundamental diagram of traffic flows on urban roads – local versus whole-link approaches [PDF]

, 2009
Fundamental diagrams of traffic flow variables have been quite useful in determining freeway operations quality. However, they are usually not used for that purpose on urban roads.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.
