Each Level Crossing (LC) has unique and typical characteristics. These high-risk intersection spots of transport
system in general and railways in particular are matter of concern all over the world. The operation of trains is under the
control of railways and at the same time road transport may be under the control of various other transport agencies. There may
be uniform road design standards and traffic operation bye-laws in a country but the movement of traffic and pedestrians are
seldom planned, monitored and regulated. This freedom and uncontrolled movement of road users make these intersections
more vulnerable to accidents.
Each year a large number of accidents take place at LCs throughout the world. The majority of these accidents occur due to the
negligence, and incompetence of road users, who generally operate their vehicles in the environment where ignorance of safety
rules and safety measures are in practice.
Human factors have been ignored till sometimes back while considering safety at railway crossings. Consequently, most of the
protection systems and alarming systems employed at railway LC relied upon technology and traditions only.
A smart, dynamic integrated system of safety net, particularly suitable for Indian Railways has been developed to take care of
various safety aspects at rail-road level crossing. The system is based on modern technology and behavioral psychology of the
road users. The system consists of digital sensors, microcontroller (AT mega 328P), buzzer, signal lights, flippers, comparator
and position encoder. It is an automatic and supposedly, fool proof system for safe operations at level crossings.
