A Ludo Cellular Automata model for microscopic traffic flow

Journal of Computational Science, 2016
Abstract The Ludo Cellular Automata (LCA) concept proposed in this paper, harnesses a stochastic approach for vehicle acceleration at microscopic level. Inspired by the traditional Ludo board game, a die roll in LCA coupled with a set of Ludo rules and biases have the potential to improve the stochasticity of traffic flow speed.

Adaptive Models for Microscopic Traffic Modelling

2021 23rd International Conference on Control Systems and Computer Science (CSCS), 2021
This paper presents, investigates and further develops microscopic simulations, using advanced capabilities from today programing environment and HPC resources, in an attempt to further develop this type of modelling towards realistic traffic configurations and large-scale applications, in the overall context of CPS - Cyber Physical Systems and future ...

Validating microscopic traffic flow models

2006 IEEE Intelligent Transportation Systems Conference, 2006
This paper summarizes the results of several projects, which were aiming at comparing different microscopic traffic flow models to reality and with each other. Surprisingly, it was not possible to calibrate model with an error smaller than 15 % (relative root mean square error, RRME) against real data.

A Microscopic Model for Lane-Less Traffic

IEEE Transactions on Control of Network Systems, 2019
In this paper, a new model is introduced for traffic on broad roads, where the drivers do not follow lane-discipline. For both longitudinal and lateral motions, the driver reactions are assumed to be influenced by possibly a number of vehicles, obstacles, and unmodeled entities in visibility cones to the front and to the sides of each vehicle.

Microscopic and Mesoscopic Traffic Models

2018
Besides macroscopic traffic flow models, traffic modelling in freeway systems has also been treated with other general approaches, resulting in microscopic and mesoscopic models. Macroscopic models can surely represent large networks efficiently, since they adopt an aggregate representation of the traffic dynamics, but they generally lack the level of ...

Microscopic Models and Traffic Instability

2020
This chapter describes some of the main microscopic models (linear and nonlinear). These dynamic traffic models involve studying local instability, asymptotic instability and flow breakdown. Moreover, a genealogy of the main traffic models (macroscopic, mesoscopic and microscopic) is reviewed in a synthetic way.

Validation of stochastic traffic flow model with microscopic traffic simulation

2011 IEEE International Conference on Automation Science and Engineering, 2011
Traffic congestion in urban areas is posing many challenges, and a traffic flow model that accurately predicts traffic conditions can be useful in responding to them. With the limitation of infrastructure and the difficulty for real world experiment, traffic simulation is a good tool for the validation and future potential applications of the traffic ...

Microscopic Modeling of Synchronized Traffic

2003
Based on a recently proposed cellular automaton model for traffic flow essential properties of synchronized traffic like the synchronization of the lanes, the pinning of a synchronized region at an onramp and the propagation of a wide jam through synchronized traffic are analyzed.

COUPLING OF MICROSCOPIC AND MACROSCOPIC TRAFFIC MODELS AT BOUNDARIES

Mathematical Models and Methods in Applied Sciences, 2010
In this paper, we investigate boundary coupling of microscopic–macroscopic models in the study of traffic flows. We propose a definition of solution through coupling of initial boundary value problems for the discrete Follow the Leader model and the fluidodynamic second-order Aw–Rascle–Zhang model in the two quadrants t > 0, x ≶ 0.

A microscopic model for phase transitions in traffic flow

Journal of Physics A: Mathematical and General, 2002
Summary: A microscopic model for phase transitions in traffic flow is presented. The basic assumption of the model is that hypothetical homogeneous and stationary, i.e. `equilibrium' states of the model cover a two-dimensional region in the flow-density plane.
