Millennium Development Goals of improving the quality of education in
secondary and primary schools, strengthening their material and technical
base, improving maternal and child health, as well as reducing maternal and

ACCIDENT RATE OF JSC "UZBEKISTAN RAILWAYS"
B. Ergashev
Abstract: This article examines the causes of accidents that are currently
occurring in JSC "Uzbekistan Railways". At present, one of the important
tasks is to ensure labor protection and production stability in railway
transport. Accidents at production facilities and damage to technical
equipment used at hazardous production facilities lead to injuries of
workers and pollution of the environment during the transportation of toxic
and hazardous substances.
Keywords:
Occupational health and safety, production stability,
emergency structures at facilities, technical equipment used in hazardous
production facilities, breakdowns, the process of transportation of toxic and
hazardous substances, injuries to workers and environmental pollution.
At present, the operating conditions of railway crossings have changed
radically. The main cause of accidents is the lack of discipline and inattention
of ATS drivers when driving on particularly dangerous sections of the road
network. Therefore, the organization of road traffic at crossings should be
focused on the creation of such traffic conditions, which would provide
timely information to road users about the presence and condition of the
crossing, as well as prevent threatening traffic safety actions.

The construction of overpasses (tunnels) along with the saving of
operational transport costs can significantly improve the safety of traffic and
pedestrians, reduce wear and tear of cars, reduce damage to goods and
accelerate their delivery, improve the working conditions of drivers of
vehicles and train drivers, improve the aesthetic quality of the road (street)
and Railways. However, such measures require large capital investments
and terms of implementation, which makes it necessary to find other
technical solutions. Total replacement of intersections in the same level
junction at different levels sometimes interfere with the topographic
conditions of the area. The replacement of the existing railway crossing with
a transport interchange at different levels is usually economically justified
at high traffic intensity values on the crossed roads.

The presence of a yellow flashing signal, which works during the period
of time when the red signals prohibiting movement at the crossing are
turned off, informs about the serviceability of the crossing alarm and
additionally indicates the move, which is especially important in the dark

and in conditions of insufficient visibility. It should be noted that in the
flashing mode, the consumption of electric energy is reduced. At the same
time, it is advisable to replace the lamp elements with led optical elements
having higher operational qualities.
The use of led heads in 2.5-3 times reduces power consumption,
increases the range of the signal and significantly increases the service life
of the traffic light. The most expedient is the installation of an additional
section functioning in the mode of yellow flashing at crossings:
⢠Category II not serviced by a duty officer;
⢠Category III without a person on duty, through which the
transportation of dangerous, bulky and heavy cargo, as well as the
movement of Shuttle buses (taxi);
⢠III and IV categories located on the railway line Brest - Orsha - Red.
Increase the level of security will also facilitate the location of moving
additional light signals, informed-bird watching road users about the
emergency on the move, malfunction LC signalling system and other
emergencies.
To inform road users about the approach of the train in a timely manner,
an audible crossing alarm is also used. In the locations of crossings near
residential buildings sound signals cause some inconvenience, especially at
night. The design of the audible crossing signalling shall provide for the
propagation of sound in the direction of the road or street, and not in space.
The quality of the sound warning of road users about the approach of the
train is largely determined by the type of sound signal used and the duration
of its operation.
An effective means of alerting vehicle drivers to approaching an iron-
road crossing, especially in foggy conditions, is to draw on all approaches to
a potentially dangerous crossing a road marking with a special configuration
and informing of the presence of the crossing. This technical solution is
widely used in the United States.
Better visibility from a small angle of view is provided by the elongated
shape of the markings. It seems optimal to use as a symbol indicating the
approach to the crossing of the image B,7a, B,7 AND A,26, provided by the
Convention on road signs and signals.
At present, on the sections of roads (streets) of the Republic of
Uzbekistan adjacent to railway crossings, the device of so - called "noise"
strips-artificial irregularities on the roadway, which create the effect of
shaking the vehicle, is becoming more and more widespread. Noise strips
are designed to draw the driver's attention to the fact that the traffic
conditions at the crossing change dramatically. Such sections of roads and
streets are usually equipped with road signs and markings, as well as
retroreflectors mounted in the roadway. Marking approaches to a railway

crossing is a simpler and more economical means of increasing the attention
of drivers as they approach the crossing. At the same time, more favorable
conditions for movement are provided, as well as a sufficiently high level of
hazard warning.
Thus, the implementation of the proposed measures will increase the
level of road safety in the zone of railway crossings by improving their
designation on the section of the road network, advance warning of road
users about the danger, equipping devices that exclude unauthorized
departure of vehicles on the move when approaching it rolling stock of
Railways and increasing the quality requirements for the maintenance of
roads and streets in the zone of crossings. The inclusion of outdoor lighting
at low-activity railway crossings located outside cities and towns at the time
of the train's entry into the approach section will improve the economic
performance of such road network facilities.
