Physical Model versus Artificial Neural Network (ANN) Model: A Comparative Study on Modeling Car-Following Behavior at Signalized Intersections

Journal of Advanced Transportation, 2022
Many studies have simulated traffic behavior at signalized intersections using various Car-Following (CF) models. However, the performance of which CF Model is superior at signalized intersections has not been thoroughly analyzed and evaluated.

Comparing the Saturation Flow Rate on the Exit Lane Between Urban Multilane Roundabouts and Urban Signalized Intersections Through Field Data

Infrastructures
Urban multilane roundabouts and signalized intersections are two major roadway devices used for controlling and managing traffic flow. This paper presents a comparative analysis of the saturation flow rate between urban multilane roundabouts and ...

Development of a Hybrid Artificial Neural Network-Particle Swarm Optimization Model for the Modelling of Traffic Flow of Vehicles at Signalized Road Intersections

Applied Sciences, 2021
The tremendous increase in vehicular navigation often witnessed daily has elicited constant and continuous traffic congestion at signalized road intersections.

Fuzzy Cellular Automata Model for Signalized Intersections [PDF]

Computer-Aided Civil and Infrastructure Engineering, 2015
At signalized intersections, the decision-making process of each individual driver is a very complex process that involves many factors. In this article, a fuzzy cellular automata FCA model, which incorporates traditional cellular automata CA and fuzzy logic FL, is developed to simulate the decision-making process and estimate the effect of driving ...

Comparative Study Analysis of ANFIS and ANFIS-GA Models on Flow of Vehicles at Road Intersections

Applied Sciences, 2023
In the last two decades the efficient traffic-flow prediction of vehicles has been significant in curbing traffic congestions at freeways and road intersections and it is among the many advantages of applying intelligent transportation systems in road ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

A Review of Safety Issue and Safety Enhancement in Dilemma Zones at Signalized Intersections

IEEE Access
Dilemma zones (DZs) at signalized intersections typically refer to the area where vehicle drivers, upon encountering a yellow light in a specific direction, hesitate between two conflicting decisions: stopping or going quickly through the intersection ...

EFFECTS OF RICKSHAWS AND AUTO-RICKSHAWS ON THE CAPACITY OF URBAN SIGNALIZED INTERSECTIONS

IATSS Research, 2004
Non-motorized vehicles (i.e. rickshaws) and small size motorized vehicles (i.e. auto-rickshaws) are popular para-transit modes that provided door-to-door service in congested parts of Dhaka metropolitan area.

Phyllopod at the intersection of developmental signalling pathways [PDF]

The EMBO Journal, 2009
One of the striking findings in developmental genetics over the past two decades is the realization that a very small number of conserved signalling pathways directs most, if not all, aspects of development of multicellular organisms, by transmitting extracellular signals to the cell nucleus, to modify gene expression programs.
