Microscopic simulations of freeway traffic flow
Proceedings 32nd Annual Simulation Symposium, 2003The article proposes novel software for traffic simulation. Traffic flow is simulated by allowing individual vehicles to move along a highway in a realistic manner. The vehicle movements are based on a fuzzy knowledge based model of highway driver behavior that contains an extensive set of rules covering all aspects of highway driving, including car ...

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 ...

A framework for the calibration of microscopic traffic flow models
, 2007 In view of the widespread use of microscopic traffic simulation models in common practice an ever more attention on their calibration related issues is bearing. These models, indeed, depend on many parameters, and the value chosen per each of them can sensibly affect model output realism.

A microscopic model for phase transitions in traffic flow
Journal of Physics A: Mathematical and General, 2002Summary: 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.

Microscopic Traffic Flow Simulator VISSIM
2010After two decades of academic research the microscopic, behavior-based multi-purpose traffic flow simulator VISSIM had been introduced in 1994 to analyze and optimize traffic flows. It offers a wide variety of urban and highway applications, integrating public and private transportation. A large part of this chapter is devoted to modeling principles of

Calibration and Validation of Microscopic Models of Traffic Flow
Transportation Research Record: Journal of the Transportation Research Board, 2005Because microscopic models are heavily used in applications, the appropriate calibration and validation of these models have been a recent concern. The contribution of this paper is to compare some of these models by calibrating and validating them with data from double loop detectors on a multilane freeway.

Toward Benchmarking of Microscopic Traffic Flow Models
Transportation Research Record: Journal of the Transportation Research Board, 2003Several microscopic traffic flow models were tested with a publicly available data set. The task was to predict the travel times between several observers along a one-lane rural road, given as boundary conditions the flow into this road and the flow out of it.

A Microscopic Simulation System for Traffic Flow with Uncertainty
Traffic and Transportation Studies (2000), 2000The uncertainty of traffic flow is the essential, unavoidable and difficult problem not only for traffic flow theory but also for traffic control and traffic route guidance. In this paper, the viewpoint for uncertainty will be provided firstly, and the uncertainty is classified into two types: subjective uncertainty and objective uncertainty.

Towards a Unified View of Microscopic Traffic Flow Theories
IFAC Proceedings Volumes, 1997Modeling and simulation of traffic has a long tradition. A vast number of different approaches have been used to simulate traffic, each of which has been calibrated and validated separately. This work aims at the way different models are interrelated.

Microscopic Traffic Flow Properties in Emergency Situations
Transportation Research Record: Journal of the Transportation Research Board, 2013Emergency situations (e.g., evacuations following a disaster) have been shown to affect traffic flow operations substantially. However, the best way to model the adaptation effects in longitudinal driving behavior underlying this impact had not been made clear.
