A car following model has been developed with particular reference to weak discipline of lane-based driving. The theory is based on the discomfort caused by lateral friction between vehicles. The movement of the following vehicle was formulated as a function of the off-centre effects of its leader(s). This incorporation of lateral friction offers a potential breakthrough in the fields of car following theory and microscopic simulation of traffic flow. Using a stopping-distance car following approach, the simulation presented in the paper pointed out the effect of the travel path width on the speed of the following vehicle, and the reduced following distance with increased lateral separation between the leader and follower. It was also shown that a special case of the proposed model (i.e. when the maximum escape speed is zero) produced the same results as the base model did for the conventional car following case. The simulation behaved rationally giving credibility to the author's staggered car following theory.read more

A Car-Following Model Considering Preceding Vehicle’s Lane-Changing Process
TL;DR: The numerical simulation results show that the model can reasonably reflect the driving decision of the following vehicle in various scenarios, and verification based on NGSIM shows that the $R$ -squared of vehicles’ speed and distance is significantly better than the FVD model, which can more effectively reflect the speed adjustment process of theFollowing vehicle during the preceding vehicle’s lane-changing process in the real traffic flow.

Studying Non-coaxiality in Non-lane-based Car-following Behavior
TL;DR: It was demonstrated that time headway threshold for initiation of car-following behavior in Iranian drivers can be approximately 2 seconds, and non-coaxiality concept was defined, where there is a significant lateral difference between the leader and follower vehicle.

Cooperative Car-Following Model of Traffic Flow and Numerical Simulation
You-Jun Liu,Hai-Lin Zhang,Li He +2 more
TL;DR: Based on the impact of a desired following speed and safe distance on driving behavior, a cooperative car-following model (CCFM) was established in this paper, and the dynamics analysis results indicate that no unrealistic deceleration or collision occurs in the CCFM.

Controlling traffic jams on a two-lane road using delayed-feedback signals
TL;DR: The results of numerical experiments are shown to verify that when the stability condition is not met, the position disturbances and resulting lane change behaviors do indeed deteriorate traffic performance and cause serious traffic jams, but once the proper delayed-feedback control signals are implemented, the traffic jams can be suppressed efficiently.

TL;DR: The findings show that an optimal value of trap length is 15m, and results show that the speed measurements based on the proposed video based method are not statistically different from the standardized equipment.

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.

In traffic flow, cellular automata = kinematic waves
TL;DR: In this paper, the authors proved that the vehicle trajectories predicted by a simple linear car-following model, CF(L), the kinematic wave model with a triangular fundamental diagram, KW(T), and two cellular automata models CA(L) and CA(M) match everywhere to within a tolerance comparable with a single jam spacing.
