Car-following models are among the most important components of micro traffic flow simulation which is studiedby transportation experts to evaluate new applications of intelligent transportation systems. Until now, several carfollowingmodels have been proposed. An obvious disadvantage of the former models is the great number of parameterswhich are difficult to calibrate. In th...

This research effort aims to compare car-following models when the models are calibrated to individual drivers with the naturalistic data. The models used are the GHR, Gipps, Intelligent Driver, Velocity Difference, Wiedemann, and the Fritzsche model. This research effort also analyzes the Wiedemann car-following model using car-following periods that occur at different speeds. The Wiedemann ca...

2 1094-7167/02/$17.00 © 2002 IEEE IEEE INTELLIGENT SYSTEMS a human-piloted lead car and one autonomous following car. The lead car sends commands and information to the following car. Using this information, the following car can either mimic the lead car’s behavior (for example, steer in the same direction) or react to information (for example, activate its brakes if the lead car is going to s...

We brieey review diierent models used nowadays in car following and lane changing for road traac simulation. We compare four recent simulators of traac and we focus on the approaches used in these simulators for performing car following and lane changing. Then we present in more details the algorithms used in the Hipertrans simulator for executing these car following and lane changing tasks.

The car-following model is a basic model of microscopic traffic simulation. The complexity of car-following behavior is suggested by a large number of factors that influence car-following behavior. Moreover, as shown repeatedly in laboratory studies of human performance, humans are very adaptable and will develop new strategies for new situations. Meanwhile, human performance and the informatio...

This research effort analyzes the Wiedemann car-following model using car-following periods that occur at different speeds. The Wiedemann car-following model uses thresholds to define the different regimes in car following. Some of these thresholds use a speed parameter, but others rely solely upon the difference in speed between the subject vehicle and the lead vehicle. The results show that t...

Due to the increasing demand for traveling in public transportation systems and increasing traffic of vehicles, nowadays vehicles are getting to be intelligent to increase safety, reduce the probability of accident and also financial costs. Therefore, today, most vehicles are equipped with multiple safety control and vehicle navigation systems. In the process of developing such systems, simulat...

This paper presents findings from a comparative evaluation of car-following behaviour in a number of microscopic traffic simulators. The paper describes the results of the calibration and validation of the car following model implemented in the ARTEMiS simulator developed by the author. The calibration and validation are based on a ‘standard’ car-following experiment (called the Boschtest) whic...
