The Value of Calibration and Validation of Probabilistic Discretionary Lane-Change Models (poster)

This paper analyses methodologies to calibrate and validate probabilistic lane change models. We perform a calibration and validation on lane change models (microscopic and macroscopic) which take the most basic dependencies into account. The resulting model has reasonable parameters, and the goodness of fit for the validation set (hold back...

The Value of Calibration and Validation of Probabilistic Discretionary Lane-Change Models

Lane changes are important in traffic flow operations. They cause differences in flow over lanes and they may determine the onset of congestion. Therefore, it is relevant to have a lane change model for which the predictive power is confirmed. This article calibrates and validates a probabilistic discretionary lane change model, both...

Quantifying the number of lane changes in traffic: Emperical analysis

Lane changes are an important aspect of freeway flow. Most lane change models are microscopic, describing whether individual vehicles/drives will change lanes, and hence are calibrated microscopically. Macroscopic validation often is restricted to the distribution of vehicles across lanes. To the best of our knowledge, no systematic analysis has...

Quantifying the number of lane changes in traffic: An empirical analysis (poster)

Since lane changes influence traffic operations, it is useful to know their frequency for various conditions. This paper studies the number of lane changes as function of the roadway characteristics. Two sites are studied, for which individual lane change data is available. The paper shows that the most constant measure is the lane change rate,...
