“…These models do not consider vehicle speeds in developing relationships of distances between vehicles with other traffic parameters like area occupancy. Linear relationship between LC and speed was assumed in many heterogeneous simulation models, such as the HETEROSIM model developed by Arasan and Koshy [12], the CASIM model by Maurya and Chakraborty [13] and the unidirectional model by Metkari et al [14]. Validation of these models was limited to macroscopic parameters only.…”

Heterogeneous traffic conditions prevail in developing countries. Vehicles maintain weak lane discipline which increases lateral interactions of vehicles significantly. It is necessary to study these interactions in the form of maintained lateral gaps for modeling this traffic scenario. This paper aims at determining lateral clearances maintained by different vehicle types while moving in a heterogeneous traffic stream during overtaking. These data were collected using an instrumented vehicle which runs as a part of the stream. Variation of obtained clearance with average speed of interacting vehicles is studied and modeled. Different instrumented vehicles of various types are developed using (1) ultrasonic sensors fixed on both sides of vehicle, which provide inter-vehicular lateral distance and relative speed; and (2) GPS device with cameras, which provides vehicle type and speed of interacting vehicles. They are driven on different roads in six cities of India, to measure lateral gaps maintained with different interacting vehicles at different speeds. Relationships between lateral gaps and speed are modeled as regression lines with positive slopes and beta-distributed residuals. Nature of these graphs (i.e., slopes, intercepts, residuals) are also evaluated and compared for different interacting vehicle-type pairs. It is observed that similar vehicle pairs maintain less lateral clearance than dissimilar vehicle pairs. If a vehicle interacts with two vehicles (one on each side) simultaneously, lateral clearance is reduced and safety of the vehicles is compromised. The obtained relationships can be used for simulating lateral clearance maintaining behavior of vehicles in heterogeneous traffic.

“…However, they have not taken into account the fact that a vehicle may not be exactly in line with its leading vehicle due to weak lane discipline in mixed traffic. Metkari et al [9] have modified an existing car-following model in order to take into account lateral movements and include mixed traffic conditions. Choudhury and Islam [10] have developed a latent leader acceleration model.…”

Heterogeneous mixture of vehicle types and lack of lane discipline are common characteristics of cities in the developing countries. These conditions lead to driving manoeuvres that combine both longitudinal and lateral movements. Modeling this driving behavior tends to be complex and cumbersome, as various phenomena, such as multiple-leader following, should be addressed. This research attempts to simplify mixed traffic modeling by developing a methodology, which is based on data-driven models. The methodology is applied on mixed traffic, weak lane-discipline trajectory data, which have been collected in India. A well-known car-following model, Gipps' model, is also applied on the same data and is used as a reference benchmark. Regarding the lateral manoeuvres, the focus is given on identification of significant lateral changes, which could indicate a lane-changing situation. Methods that allow monitoring structural changes in regression models could be used for this purpose. The ability of capturing lane changes is explored. A typical example is illustrated and further discussion is motivated.

“…The vehicles rate of change of heading angle also reduces at higher speed. Metkari et al (2013) clubbed the two models inspired by the Gipp's model, one covering the aspect of weak lane discipline and another, the vehicle type dependent behaviour. The study was conducted for uninterrupted unidirectional traffic on straight and level mid-block section in Delhi.…”

Lateral distribution of vehicles across the carriageway was the most important characteristic of traffic with little lane discipline. The absence of lane behaviour implies that a driver not only interacts longitudinally with the vehicles ahead but also laterally with vehicles on its sides. The discipline of lane based driving can be examined from the lateral position of vehicles across the carriageway. An analysis of lane changing behaviour indicates characteristic differences in lane changing for distinct vehicle-types. In this study, an attempt is made to understand non-lane based behaviour of traffic in which lateral distance keeping behaviour, lane keeping behaviour and lateral behaviour of vehicles are studied. The effect of traffic composition on lane wise headway behaviour of vehicles is studied. In order to analyse the lateral position of vehicles across the carriageway, the central position of vehicles were noted for different vehicle-types. These positions were noted for each of the median, middle, shoulder lanes and the paved shoulders as the vehicles passed a particular reference line on the carriageway. Lateral clearances of various vehicle-types are also compared in this study.
