dispatching system is usually complex, including
negotiations and technological operations. To
improve the technological processes of urban
passenger transport operational dispatching
management, these operations can be integrated
into a single complex for the situation that occurs
in each operational environment. This automated
dispatch management system requires a science-
based approach to situation management tailored
to the dispatcher. The operating mode of the
automated dispatching system is a regular mode
of operation, which consists of controlling the
process of routing passengers on a pre-
established and announced schedule of urban
passenger transport. However, relatively minor
disturbances of the transport process are offset
by the regulatory impact of the control system.
However, there are cases when it is not possible
to carry passengers according to a pre-arranged
schedule when operating transport in the
conditions of high-density traffic flows. Let’s look
at the conditions under which the dispatch
system can move to situation management.
M
ATERIALS AND METHODS
To improve the technological processes of
automated dispatching management of urban
passenger transport, the following basic rules
have been formed, which substantiate the
possibility of using situational management
methods.
1)
There is no universal approach to dispatch
management. Different problem situations
during transportation require different
approaches to solving them.
2)
Situational probability factors should be taken
into account in the technological processes of
the automated control room to achieve
effective decision-making in the management
of urban public transport complex.
3)
There are many ways to achieve the goal of
increasing the efficiency of ADMS operating in
high-density traffic flows.
4)
The results of the same control effect of the
dispatcher as part of the operating control
room may differ from each other depending
on the current traffic situation on the route
network.
5)
Any management problem related to possible
failures and interruptions in the performance
of transport operations may be close to any
other problems.
When deciding on any direction of urban
public transport or passenger transport, the
impact of this decision on other control
objects of the automated dispatching system
should be considered.
6)
The implementation of the ADMS control
effect on the dispatcher should be based on
the situation in which they were received.
7)
The operating control room should be based
on the most repetitive operations, primarily
due to the high degree of automation of the
main functions of the dispatcher, which allows
the system dispatcher to correctly identify
and assess the traffic situation and the most
effective management allows you to select
methods.

Thus, in order to adapt the situational approach
to the operational problems of the public
transport dispatch department, it is necessary to
solve the following main tasks:
a)
Create a model to represent multiple
situational factors and situations in the form
of ADMS situation variables (situation
model);
b)
Creation of a model of the functional ratio of
situational variables of the transport process
and
internal
features
of
ADMS
(communication model);
c)
Ensuring automated decision-making and
implementation of management impacts on
the transport process as part of SME activities
based on the above models.
Within the framework of the formation of a model
of the functional ratio of the situational variables
of the transport process and the internal
characteristics of the ADMS, the main reasons for
the need to shift the management system to
situational management are:
Sudden and unexpected deterioration of
transport conditions, which makes it
impossible to transport in a certain mode;
Blocking off a part of the route network due to
road traffic accidents, and emergencies.
Automated decision-making and implementation
of management impacts on the transport process
as part of public transport activities should be
carried out within the framework of the formal
formation of a complex facility management task.

provides a set of information about the control
object, as well as information about the status of
the control system. Then, the initial action of the

number of possible effects, many possible cases
are divided into n classes, each of which
corresponds to one of the possible control effects.
If the same situation falls on more than one class,
this means that multiple control effects can be
selected. Such conversion was called a logical-
transformational rule. Here is a clear example of
the interpretation of the formed logical-
transformational rules of the dispatching system.
A complete list of logic and transformational rules
defines the ability of a control system to influence
the processes it controls. The software complex of
the dispatcher must be technologically capable of
using all the necessary data in an automated or
automatic mode during operation. In particular,
in the event of any external and internal
disturbances, it is necessary to ensure the same or
close computational range of the movement
moving with the movement composition on the
route. The implementation of this technology
should, in fact, take into account the procedure for
creating real-time action plans that adequately
respond to events occurring along the route. In
case of complicated road conditions, the

dispatcher's motion algorithms should be
developed. Thus, the effective use of situational
management methods in the technological
processes of automated dispatch control of public
transport, mainly the analysis of information in
the form of diagnostic signs of the situation, the
movement of vehicles on routes and the
elimination of irregularities in the process of their
elimination. Based on the distribution of
priorities between rt, depends on the efficiency of
detection of the dispatcher. A typical scheme for
selecting a control effect is shown in Figure 1. The
control system generates information about the
full current S1 status that is included in the input
of the “analyzer”. The task of the “analyzer” is to
assess the current situation and determine the
need to intervene in the process occurring at the
facility.
Fig. 1. A typical scheme for selecting a control effect
If a particular situation occurs, the data is entered
into a “classifier,” which refers to one or more
classes of the situation that are eligible for a
single-stage control effect. This information is
transmitted to a “correlator” that stores all logical
and transformational rules. A “correlator” defines
a logic-transform rule (LTR) that can be used in
this situation. If the “correlator” is only looking
for a logical and conversion rule, it is given to the
object as a control effect. If the “correlator” is
looking for multiple LTR, they are sent to an
“extrapolator” whose task is to evaluate the
alternatives of the control effect and select the
best option for the “correlator”. In addition, the
“correlator” transfers this control to the object to
perform the effect. If according to the
"extrapolator", there are possible solutions equal
to several effects, then the correlator transfers
these decisions to a random selection block,
which is the number of controls transmitted to
the control object for execution. Makes the final
choice of the secret.

ONCLUSION
1.
Based on the analysis, the main factors and
causes of situations arising in the process of
urban passenger transport were identified.
The role of the dispatcher in the traffic
regulation process has been identified. The
source of the high labour intensity of the
control room is a large part of the manual
operations in the analysis of the situation.
2.
The analysis and systematization of
technological operations of the control room
were carried out depending on the nature of
the impacts.
To increase the level of automation of
technological operations for each specific
operation of the regulation of the transport
process, diagnostic signs indicating the
occurrence of the situation in an automated
mode should be created and applied. It has
been shown that with a clear consistency of
this feature and situation, it is possible to fully
automate the management effect or to ensure
a sequence of actions to implement it.
3.
The main features of the use of information
technology
in
the
development
of
technological operations of dispatching
management of automated navigation
systems for public transport management
were analyzed. Increasing the automation and
efficiency of the information retrieval process
and the inclusion of relevant information in
the system database will significantly increase
the efficiency of dispatching operations.
4.
Analysis and adaptation of the principles of
situational management in order to use them
in improving the technological processes of
