A Microscopic CA Model of Traffic Flow?
, 2018 Cellular automaton (CA) models of traffic flow are typically constructed to reproduce macroscopic features of traffic flow. Here, a few thoughts based on real car-following data are presented that show how to construct a discrete time/discrete space microscopic model of traffic flow.

Real-Time Traffic Simulation With a Microscopic Model
IEEE Transactions on Intelligent Transportation Systems, 2006This paper describes a microscopic model that is able to simulate traffic situations in an urban environment in real time for use in driving simulators. Two types of vehicles are considered in the simulation, namely the user-driven vehicle at the center of the simulation model and the other vehicles that interact with it and its surroundings, which ...

A Ludo Cellular Automata model for microscopic traffic flow
Journal of Computational Science, 2016Abstract 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.

A Microscopic Model for Lane-Less Traffic
IEEE Transactions on Control of Network Systems, 2019In 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.

Validating microscopic traffic flow models
2006 IEEE Intelligent Transportation Systems Conference, 2006This 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.

Validation of stochastic traffic flow model with microscopic traffic simulation
2011 IEEE International Conference on Automation Science and Engineering, 2011Traffic 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 and Mesoscopic Traffic Models
2018Besides 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
2020This 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.
