INTRODUCTION
The system of state management of the road sector of the republic has a number of problems and disadvantages that hinder the formation of a competitive environment and attract investment in the industry. In particular, the lack of a long-term strategy for attracting investment in the road sector, including on public-private partnerships, does not allow the use of alternative sources of financing for work, placing the main financial burden of expenses on the State budget.
In accordance with the Decree of the President of the Republic of Uzbekistan dated December 9, 2019 No. DP-5890 "On measures to deeply reform the road system of the Republic of Uzbekistan", as well as to further improve the management system of the road sector of the republic and increase its investment attractiveness with the involvement of leading foreign experts and consultants, on September 1, 2020, submited to the Cabinet of Ministers of the Republic of Uzbekistan a Strategy for the Development of Roads until 2030, including: increasing the transit and logistics potential of the republic through the development of a network of modern highways of international importance and expressways, as well as their integration into international transport corridors; consistent reduction of the budget load by attracting investments, funds of international financial institutions, as well as the implementation of projects on the terms of public-private partnerships; the gradual increase in the cost of operating roads by

2022 by at least two times; application of an internationally recognized methodology for the selection and evaluation of the highest priority projects in the field of road construction, as well as forecasting the effectiveness of their implementation; the introduction of new technologies and programs for managing road assets that monitor the condition of roads, collecting and maintaining the necessary statistics; the use of modern traffic management systems for the efficient use of existing road infrastructure [1].
MATERIALS AND METHODS
The Urban Roads Management System (URMS) is the result of extensive research conducted at the University of Texas at Austin by Dr. Xin Chen, Dr. W. Ronald Hudson, and Terrence E. Dossey. URMS is a comprehensive road surface management system designed primarily for use in small and medium-sized cities. The system provides public works managers and engineers with a computerized tool that helps them manage their roads and streets effectively and efficiently at both the network and project levels. Simple, flexible and user-friendly, the software is designed to run on any IBM personal computer (or compatible) with a VGA monitor, and therefore seems to be available even in small towns. The main feature of the program is that, unlike other available software, it can provide useful results with minimal data entry and can be easily adapted to specific road damage problems and the rehabilitation decision-making process in each individual city. It has a user-friendly graphical interface, which is designed to be easily accessible to people who are not familiar with personal computers [2, 3].
A simple urban pavement design system was described in [4], illustrating such systems. Implementation of similar systems such as StreetSaver® by the Metropolitan Transportation Commission (MTC), which was developed by Dr. Roger Smith of Texas A&M University, engineer Sui Tan MTC and their team in [5, 6].
RESULTS AND DISCUSSION
Lisbon, Portugal. In 1999, the city council in Lisbon, Portugal, decided to develop a pavement management system for its road network. [7] The system was the result of a collaborative effort by engineers from the University of Coimbra, Portugal; University of the Interior of Beira, Portugal; and the City Council and the Road Protection Department of Lisbon, Portugal. Basic development took two years, and preliminary implementation of the system began in 2001. It consisted of three main modules: a road network

database, a quality assessment tool and a decision aid tool, which took over two years to develop. As you might expect, a number of difficulties arose during the development. But additional development was planned for the period after 2004.
City of San Antonio, Texas. In 2009, the City of San Antonio requested road surface management services to include inspection of approximately 4,000 central miles of city streets. Fugro Consultants, Inc. [8] assisted the City in collecting and processing data for the roadway and in taking inventory of roadside property, including sidewalks, ramps, water intakes, signs, hatches and water valves. Along with a partnership of two sub-consultants, ADA compliance checks were carried out on more than 50,000 ramps on city streets. Pavement information was uploaded to the Cartegraph pavement management system [9] and a budget analysis was provided to the City for long-term planning. Geodatabases have been created for sidewalks, ramps, intakes, and signposts.
PMS Metro Nashville selection process. In 2008, interviews were conducted with PMS software vendors to explore and evaluate possible pavement management systems to develop a long-term strategic pavement plan for the Nashville and Davidson County metro [10]. Many candidate systems were rejected early in the process due to cost or volume. Systems with software costs over $ 50,000 were rejected. Other packages were rejected because the vendor required the customer to purchase the service in order to receive the (often proprietary) software. However, other packages were rejected as insufficient for the size and scope of the metro's road network. Ultimately, Cartegraph's PAVEMENTviewPLUS was selected for implementation in Nashville and Davidson County. Factors such as ease of use, learning curve and cost were key factors in the decision, the agency said.
Pavement Management in Johannesburg, South Africa. Not all ICPs are developed in North America. Much work has been done in South Africa, for example, especially in the city of Johannesburg, which has a road network of about 10,000 kilometers, including highways, major and minor highways, sewers, official suburban roads and roads in informal settlements. [11] Both paved and unpaved roads. The city introduced its first PMS in 1975 with the help of the National Institute of Transportation and Highway Research (NITRR) laboratory. Doctors Around this time, Haas and Hudson were lecturing and teaching short courses in South Africa at NITRR, and their concepts were incorporated into pavement management activities in South Africa. Until 2002, when the new system was approved for implementation, a number of updates to the city PMS were made,

including GIS; The new system introduced the latest PMS technology at the time and focused on innovative methods such as:
- Improving the accuracy and completeness of the roadmap.
- Correction of the location of roads in the field, the names of the streets of which were missing.
- Integration of optimal maintenance and rehabilitation analysis and identification of roads, such as highways and highways, which deteriorate mainly as a result of traffic load compared to suburban roads and other roads, which deteriorate mainly as a result of aging of the environment and surface.
- Programming the modernization and maintenance of dirt roads, the condition of which may deteriorate overnight as a result of heavy rains.
GIS Based Pavement Management System - Fountain Hills, Arizona. Around this time, Medina, Flintsch, and Zanevski developed and implemented a GIS-based PMS in Fountain Hills, Arizona [12]. A study from the University of Arizona conducted a case study in which they developed a prototype low volume PMS road based on a city GIS platform. For the study, the city engineer provided the already assembled inventory and condition database, as well as a city map in AutoCAD. After evaluating several software packages, the team selected the Road Surface Management System (RSMS) package, which was developed at Arizona State University, as the underlying PMS platform. This program was designed to help local agencies in Arizona systematically manage low-volume road and street sidewalks. During the study, the researchers evaluated two GIS packages and chose MAPinfo because it was less expensive and easier to learn than other packages. A menu-driven MAPinfo application that launches RSMS software, imports a pavement maintenance and restoration program, and interactively prepares and displays color maps with analysis results. The combination of RSMS and MAPinfo significantly reduced the effort required to develop the prototype system, which the city implemented using existing digital data.
CONCLUSIONS
In many countries, road infrastructure is the most important of all public assets. Lack of information and political awareness on the importance of sufficient investments for the maintenance of the road infrastructure lead to its chronic underfinancing and deterioration. As a consequence, it can no more offer the required level of service and loses its value. In any
economic situation we should be aware of the importance of

spending money in a very efficient and responsible way today and in the future. This requires the implementation of innovative approaches.
What can we do to contribute to better roads and sustainable road management?
As a decision maker:
- Recognize roads as an asset for the society;
- Take initiatives to implement Road Asset Management, including objectives, financial framework and strategies;
- Support road authorities by providing necessary funding for timely and sufficient maintenance and improvement of the roads;
- Communicate to all the stakeholders (road authorities, citizens, road users...).
As a road authority:
- Start establishing an inventory of our road infrastructure and conducting regular surveys;
- Ensure transparency in the implementation of the RAM process;
- Convince politicians of the benefits of RAM to the community;
- Implement the process on a regular basis.
As a citizen:
- As a citizen and a tax payer we deserve a road infrastructure that brings us the expected level of mobility, safety and service;
- Make our voice heard and put pressure on decisions makers for maintaining and improving the road as an asset and a public utility;
- Ensure that roads are systematically considered as a priority by all the concerned stakeholders.
