This article highlights problems related to traffic flow management in the process
of designing internal roads in the cities of Uzbekistan. Conditions such as traffic jams, incorrect
positioning of traffic lights, and lack of parking spaces were analyzed in general. On the example
of some cities of the republic, the causes of the problem are revealed, and practical proposals for
their elimination are put forward.

Introduction.
Today, the cities of Uzbekistan are developing rapidly, the population and the
number of vehicles are growing significantly. This situation, in turn, creates the need to update
and expand the infrastructure of internal roads and effectively manage traffic flow. Internal city
roads are important not only for traffic, but also for the movement of pedestrians, public
transport, and emergency services [1-3]. However, in practice, problems related to traffic flow -
traffic jams, incorrect positioning of traffic lights, lack of parking spaces, etc. - are widespread.
This article analyzes problems related to traffic flow management in the design of internal roads
using the example of cities in Uzbekistan and puts forward proposals for their solution [4].

Methodology.
Main problems in the design of internal city roads
:
The system of internal roads in
the cities of Uzbekistan does not fully meet the ever-increasing traffic flow. The basis of the
problem lies in the fact that the existing infrastructure is built according to outdated standards,
and modern approaches are not sufficiently applied in urban planning [5,6]. Traffic jams have
become commonplace, especially in large cities - Tashkent, Samarkand, Andijan, Namangan,
and Fergana. The reasons for this are the non-compliance of road widths with the standard, the
lack of automation of traffic lights, and the inefficient planning of intersections. The lack of
coordination of traffic light systems, which is one of the main means of managing traffic flow, is
the reason for the accumulation of traffic at many intersections. This problem is especially acute
in the morning and evening hours, when going to work and returning from work. In addition,
improper coordination of pedestrian and public transport movement also negatively affects the
consistent movement of traffic flows. On many city roads, there are no pedestrian paths or they
are narrow, and pedestrians are forced to walk on highways. The lack of dedicated lanes for
public transport leads to buses and minibuses getting stuck in traffic jams, which leads to a loss
of time for the population.
Suggestions for Troubleshooting
- To address problems related to traffic flow management on
city roads, the following suggestions are proposed:
-
It is possible to liberalize traffic flow by redesigning road infrastructure, expanding
existing roads, optimizing intersections, and building new, modern intersections. In particular,
the introduction of one-way traffic will reduce traffic congestion on some narrow streets.
-
By connecting traffic lights to intelligent control systems (ATS - automatic transport
system), it is necessary to implement traffic density-based algorithms. This helps optimize flow
during rush hour.
-
The development of a parking system can reduce parking problems on central streets by
building multi-story, underground, or remote parking lots. In this case, a procedure will be
introduced through a paid parking system.
-
Prioritizing public transport, allocating separate lanes for buses and routes, updating
public transport, and fully connecting it to the GPS system can increase the efficiency of
transport services.
-
The construction of wide, safe pedestrian walkways and underground/passage roads
along roads to create conveniences for pedestrian traffic serves to separate pedestrian and vehicle
traffic. This ensures overall traffic safety.
Results and Discussion
Efficient traffic flow management on internal city roads is a complex issue that impacts not only
road infrastructure but also social, economic, and environmental aspects. This paper has
identified the major problems encountered in managing urban traffic flow and proposed
actionable solutions for their mitigation.
In many cities, especially in developing regions, urban road networks are planned without
adequate consideration for traffic volume and road capacity. This results in narrow streets,
inefficient intersections, and poorly placed traffic signs, leading to congestion. In several urban
areas, traffic management systems are outdated and fail to meet modern demands. This
contributes to increased traffic congestion and reduces road safety. City road infrastructure is
often designed with a bias toward motor vehicles, with little or no infrastructure for pedestrians

and cyclists. This not only affects pedestrian safety but also contributes to environmental
degradation.
Proposals:
Promote the use of environmentally friendly vehicles such as electric and hybrid models.
Develop urban transport policies that consider social impacts and public well-being.

Conclusion.
The problems considered above and proposals for their elimination show that the
cities of Uzbekistan face the need to modernize the infrastructure of internal roads. The current
situation has a direct impact not only on traffic, but also on the quality of life of the city's
residents and the ecological environment. Effective operation of the urban transport system can
be achieved by properly managing traffic flow, preventing traffic jams, facilitating public
transport movement, and creating conditions for pedestrians. The proposed measures - the
expansion of infrastructure, the introduction of smart management systems, the expansion of
parking lots, and the prioritization of public transport - are based on modern road engineering
approaches. Effective operation of the urban transport system can be achieved by properly
