A STUDY ON GEOMETRIC ELEMENTS FOR CONTROL OF ACCIDENTS RATE IN HIGHWAYS

Abstract

In India, the number of people killed in traffic accidents has risen steadily over the previous decade or
so. As a result, scholars throughout the globe are debating traffic safety management. Because of this, a
variety of elements must be considered while doing accident modelling. Modeling an accident allows us
to identify the true culprits responsible for the incident. One reason may have a higher impact than the
other. Accident modelling is the only way to discover these underlying causes. For the sake of this
research, we have attempted to categorise these accident modelling approaches into two separate
groups, one for urban roads and one for rural roads.It's been shown that accident investigation models
vary widely, depending on the industry, domain, and investigative focus. Research on human variables is
particularly susceptible to a broad range of approaches. The bulk of these theories may be traced back
to the Rasmussen model of system hierarchy or the Swiss Cheese causality model developed by
Reason.There are a lot of models that come from manufacturing and the energy sector in general. The
use of these concepts in the aviation sector has shown their fundamental flaws. In reality, their
intervention potential is confined to linear solutions because of their simplifications and lay
interpretations. When designing for a multi-actor environment, a comprehensive systems engineering
design approach should be employed. Three paradigm adjustments in investigative methods are
required for such an approach. To begin, there must be a severance of ties between the fields of event
modelling and systems modelling. There must be a distinction made between two distinct categories of
design. Linear alterations to the current design envelope are distinguished from second-order
alterations that aim to expand the design solution space. Third, building safe solutions in a multi-factor
systems context needs prototyping, virtual system model simulation, and testing of limit state
scenarios.. On the basis of these limitations, a framework for improving aviation safety is provided,
which is based on actual experiences in the industry. As a result of new concerns about cost, safety, and
the environment, undivided interurban road geometry has evolved throughout time. Initial design
