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 two-sided lateral gap continuum model and its numerical simulation for non-lane based heterogeneous traffic environment
TL;DR: A new continuum model by considering the properties of two-sided lateral gap in a non-lane based heterogeneous traffic stream is proposed, which improves the stability region of traffic flow and increases the capacity and density of traffic stream.

Lateral Placement of Vehicles on Horizontal Curves
TL;DR: In this paper, the authors conducted a placement study on horizontal curves and found that the vehicles were generally observed to shift towards center with increase in road width on curves and the percentage shift was found to decrease.

TL;DR: A dynamic discrete choice model is proposed to capture the lateral-shifting behaviors of PTWs in mixed traffic conditions and it is shown that a better model fit is obtained when taking into account the dynamic nature of the problem.

The non-lane-discipline-based car-following model considering forward and backward vehicle information under connected environment
TL;DR: In this paper, a car-following model without lane discipline is proposed, which considers forward and backward vehicle information and lateral gaps effect by assuming that vehicle information can be obtained through V2V communication.

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.
