A model for the structure of lane-changing decisions
TLDR
A structure is proposed to connect the decisions which a driver has to make before changing lanes to ensure that the vehicles in traffic simulations behave logically when confronted with situations commonly encountered in real traffic.Abstract:
A structure is proposed to connect the decisions which a driver has to make before changing lanes. The model is intended to cover the urban driving situation, where traffic signals, obstructions and heavy vehicles all exert an influence. The structure is designed to ensure that the vehicles in traffic simulations behave logically when confronted with situations commonly encountered in real traffic. The specific mathematical expression of the questions embedded in the decision process and employed in the present implementation of the model are not critical and can be replaced by alternatives, but the heirarchy of the decisions is crucial. On the basis of experience to date, the lane changing model produces a realistic simulation of driver behaviour and has proved very robust under a wide range of conditions.read more

Comparisons of mandatory and discretionary lane changing behavior on freeways
TL;DR: Comparative analyses on drivers’ behavior during mandatory and discretionary lane changes by examining the statistical properties of four lane changing decision variables that describe the gaps between the subject vehicle and the surrounding vehicles show that, for the three decision variables associated with gaps in the target lane, the means and distributions are not significantly different.

A pattern recognition algorithm for assessing trajectory completeness
TL;DR: A pattern recognition algorithm to objectively, accurately, and automatically differentiate different driving regimes in a trajectory and then select the most complete trajectories (i.e. trajectories containing a maximum number of regimes), based on Dynamic Time Warping and Bottom-Up algorithms is developed.

Modeling accident risks in different lane-changing behavioral patterns
TL;DR: This study investigates the contributing factors to accident risks in different lane-changing patterns with taking unobserved heterogeneity into account and proposes alane-changing risk index (LCRI) to evaluate the risk level of each vehicle group.

Application of Relaxation Procedure for Lane Changing in Microscopic Simulation Models
TL;DR: It was seen that the value of the sensitivity factor required to reproduce any particular merge capacity in this revised model increased to physically realizable values as the relaxation time is increased, whereas non-physical values were required in the existing FRESIM model to produce equivalent merge capacities.

A behavioural car-following model for computer simulation
TL;DR: A new model is constructed for the response of the following vehicle based on the assumption that each driver sets limits to his desired braking and acceleration rates and it is shown that when realistic values are assigned to the parameters in a simulation, the model reproduces the characteristics of real traffic flow.

Nonlinear Effects in the Dynamics of Car Following
TL;DR: In this paper, it was shown that a small amplitude disturbance propagates through a series of cars in the manner described by linear theories, except that the dependence of the wave velocity on the car velocity causes an accleration wave to spread as it propagates and a deceleration wave forming a stable shock.

A Generalization of Linear Car-Following Theory
TL;DR: The linear theory of single-lane traffic flow is generalized by using an integral transform technique well-known in other branches of applied science that introduces the idea of a memory function that describes the way in which a driver processes the information he receives from a lead vehicle.
