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

Evolution of macroscopic models for modeling the heterogeneous traffic: an Indian perspective
TL;DR: The tradition through which the evolution of macroscopic modeling of heterogeneous traffic has happened does not account for some of the phenomena observed in the Indian road traffic, and one such phenomenon, side-by-side movement of motorized two-wheelers (TW), is explained and an idea of diminishing density is introduced, which would improve the usability of the existingheterogeneous traffic flow models in an Indian perspective.

Review of Studies on Mixed Traffic Flow: Perspective of Developing Economies
M Sai Kiran,Ashish Verma +1 more
TL;DR: In this paper, a review of the studies on various mixed traffic characteristics in developing economies, identify their limitations and provide guidelines for the future research is provided, and a detailed methodology of the simulation process for the mixed traffic is given, reflecting the "gap-filling" rather than the conventional car-following behavior.

Operating speed prediction model as a tool for consistency based geometric design of four-lane divided highways
TL;DR: Researchers have studied two-lane rural highways to predict the operating speed on horizontal curves and correlated it with safety, and two nomograms are suggested for conventional design, consistency based design and geometric design consistency evaluation of four-lane divided horizontal curves.

Analysis of microscopic data under heterogeneous traffic conditions
TL;DR: In this article, the lateral distribution of vehicles on a ten-meter wide road has been analyzed with a specific emphasis on motorized two-wheeler movement using trajectory data, an attempt to examine the gap maintaining the behaviour of vehicles under different traffic conditions has been made.

Multivariate analysis of microscopic traffic variables using copulas in staggered car-following conditions
TL;DR: The findings of the study justify the need to explicitly consider centreline separation and vehicle speed in time headway modelling for elucidating the integrated driving behaviour of non-lane-based traffic streams, a proper consideration of which will further ameliorate the realistic replication of rider’s behaviour in simulation modelling.

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.
Book
Traffic flow fundamentals
TL;DR: The remaining portion of the book, Chapters 8 through 13, is devoted to analytical techniques involving the total traffic flow situation; chapter subjects are, respectively, demand-supply analysis, capacity analysis, traffic stream models, shock wave analysis, queueing analysis, and computer simulation models.

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.
