Systematize, supplement and complete the theoretical basis, legal basis and practical basis for the work of exploitation management of urban road transport infrastructure - Analyze and assess the current status of exploitation management of urban road transport infrastructure in the specific urban area of Ho Chi Minh City Evaluating the shortcomings and limitations in terms of management such as: Management model; Managing method; Mechanisms - policies of training management; Science and technology application; Maintenance budget The consequences including: the technical quality of projects is not guaranteed; traffic safety; invasions of roadways, sidewalk; Urban flood, etc - Propose groups of solutions to improve the management and exploitation urban road transport infrastructure in Ho Chi Minh city CHAPTER 2: RATIONALE AND THEORY IN MANAGEMENT OF EXPLOITATION AND MAINTENANCE OF ROAD TRANSPORT INFRASTRUCTURE 2.1 Road transport infrastructure 2.1.1 Definition of uraban road transport infrastructure Urban road traffic transport is a system of urban traffic technical infrastructure such as bridges, roads, underground tunnels, stations - parking lots, maintenance stations, etc and supporting facilities, meeting the convenient and safe requirements of people and goods transportation 2.1.2 The components constituting the uraban road transport infrastructure The urban traffic traffic system is composed of: dynamic traffic system and static traffic system 2.1.3 Classification of road and urban road traffic systems Management level: National highways, provincial roads, district roads, commune roads, urban roads, specialized roads Functions: non-urban and urban roads Technical level: non-urban roads consisting of express ways, roads from level to VI 2.1.4 Role of road transport infrastructure Satisfy the demand of manufacturing and living of urban residents; develop economy in the urban and suburb areas; set the foundation to attract more investments 2.2 Management of exploitation of urban road transport infrastructure 2.2.1 Concept of management of exploitation of urban road transport Management of exploitation of urban road transport is the management activity during the operation of construction works, the impact of management owners to the exploitation, to maintain the technical status, architectual space, maximize the capacity, safety in exploitation, save maintenance and management costs 2.2.2 Urban road transport management decentralization - The Department of Transport of a province/city: performs the function of state management, authorizes the relevant units to manage the exploitation, including: the national highway system (authorized by the Ministry of Transport); provincial and city road system; urban roads - People's Committee of districts: State management of district, district, ward and commune road system Authorizing the Management Board for construction investment in the district to manage the maintenance of the relevant roads 2.2.3 Content of management of exploitation of urban road transport 2.2.3.1 Technical management of urban road transport construction Technical document management; monitoring technical status of the construction works; classification and evaluation of construction works; registration documents and archives 2.2.3.2 Management of operation activities a Plans to ensure transport safety, reduce congestion and traffic accidents The measurements to ensure the transport safety in exploitation; solutions to settle the congestion, flood, accidents; measurements to divide traffic directions upon arising incidents; ensure the quality of roads’ surface, lighting systems, drainage system, signal lights, etc Monitoring the “serious locations” of accidents and safety transport b Management of solutions to protect construction works and road safety barriers - Protected subjects: all the construction works - Protected scale: the works on surface, in the air, underground and road safety barriers - Protection responsibility: all the competent authorities and society c Management of road transport infrastructure Maintenance of road transport works: the obligations to follow procedures, standards and other legal documents to ensure the exploitation in quality, efficiency, longevity of the works, etc Term for maintenance of road transport infrastructure: from the handover of works to the termination of usage term Level of maintenance the works: as per the Decree No 46/2015/NĐ-CP of Vietnam government regarding the quality management of construction works Methods of managing the maintenance of urban road transport works: - Managing as per process (MBP): taking attention to the procedure of each work; everyone understands clearly each work and is authorized to perform their jobs - Managing as per target (MBO): taking attention to the final outcome of the work; respecct the contracts, plans specified in such contracts 2.2.3.3 Management of cost and capital creation in construction exploitation a Management of repair and maintenance cost and operation cost: It is the management of direct costs used for repair and maintenance and for management system to satisfy the requirements of work exploitation operation - Method of determining the cost of works maintenance: The method is determined by the estimate by volume and unit price; The method is determined according to the percentage rate - Structure of construction maintenance costs: Expenses for maintenance planning, regular - periodic - irregular inspections, costs for preparing and managing maintenance records; monitoring and repair of minor damage, determined by percentage rate (%) compared with the cost of construction and the cost of work equipment calculated by the investment capital of works of the same level and type at the time maintenance planning - Control maintenance costs: to be paid according to the estimate made and appraised before the maintenance The volume settlement work is under the control of the State Budget and an independent audit b Capital creation in exploitation management Capital classification of management of exploitation of urban transport infrastructure - For state-owned works managed by the central government, the capital for management and maintenance shall be allocated from the central budget and other capital sources according to the provisions of law - The works are managed by the locality, the capital is allocated from the local budget, partly from the central maintenance fund Management and use of capital for maintenance of urban road transport infrastructure: - Subjects eligible to use capital: + Performs three types of maintenance work: regular maintenance; periodic maintenance; unexpected repairs + Costs for management activities and for the inspection system and other activities Plan on using, allocating and settling capital - For centrally-managed works, the Ministry of Transport shall make a plan and cost estimate and submit it to the National Assembly for approval Budgeting through the Ministry of Finance and the State Budget - For construction systems of localities, including capital sources: + Funds allocated by the Central Government from capital sources for work maintenance (Construction Maintenance Fund) + Capital allocated by the local budget, the Department of Transport (authorized subordinate units to act as investors) prepares an estimate of costs for management and maintenance urban road transport infrastrucure and transfers them to the Department of Finance and submits them to the People's Council of the city for consideration and approval Capital creation in exploitation - Collection of operating fees (tolls) 11 2.4.2 Factors affecting the cost of management and operation of urban road transport infrastructure Affecting factors The impact of the work quality on the operating costs Impacts of changing environmental factors caused by natural disasters and climate change Effects of not timely arrangement of funding for maintenance and management activities The influence of the model methods of management Figure 2.9: Factors influencing the cost of management and operation of urban road transport infrastructure 2.5 Legal basis for the exploitation management of urban road transport infrastructure The legal documents related to the technical management of the road system in general, the urban road transport infrastructure in particular have basically been completed Decrees, Circulars and a number of other legal documents have been issued by the Government, Ministries, and People's Committees of localities, in accordance with local characteristics In which, Decree No 46/2015/ND-CP dated May 12, 2015 of the Government on quality management and maintenance of construction works is the main legal basis of the exploitation management of urban road transport infrastructure 2.6 Practical basis for the exploitation management of urban road transport infrastructure 2.6.1 Experience in managing and exploiting urban road traffic works of some countries in the world 2.6.1.1 Experience of Korea Korea socialized the exploitation management; Investor selection through public bidding and evaluation scale; Promote IT application in traffic organization management 2.6.1.2 Experience of Singapore In Singapore, to generate revenue for road maintenance, the Government implements a toll collection policy with three types of fees: road using fees; personal vehicle restriction fees and traffic congestion charges 12 2.6.1.3 Experience of Japan Applying performance and performance-based road maintenance (PBC) contracts, through open bidding, entrusting private contractors to maintenance work, with local authorities only perform state management functions 2.6.2 Lessons learned about the exploitation management of urban road transport infrastructure in Ho Chi Minh City - Separate functions of state management and business management in exploitation management - Selection of contractors for maintenance work through competitive bidding - Apply MBO maintenance management method through performance-based contracts and quality (PBC) - Generate capital through road toll collection - Socialize the exploitation management of the road system, through attracting the private economic sector - Strengthening the IT application of technical management of road systems CHAPTER 3: THE STATUS OF THE MANAGEMENT OF EXPLOITATION OF URBAN ROAD TRANSPORT INFRASTRUCTURE IN HO CHI MINH CITY 3.1 Overview of the road transport system in Ho Chi Minh city Roads are the main transport method; all the requirements for evaluating the road transport not satisfy the special city; the city is inbalanced between indivual transport development and transport infrastructure, creating certain pressure on the urban road transport infrastructure system; the static transport system does not satisfy the planning and usage 3.2 Analysis and assessment of the current situation of the exploitation management of urban road transport infrastructrure in Ho Chi Minh City 3.2.1 Decentralization of the management of exploitation of urban road transport infrastructure in Ho Chi Minh City - Department of Transport is the stage management agency managing the national ways; urban roads; the management level spreads down to 04 sub-agencies which are urban transport management and Sai Gon river tunnel management center 13 - People committees of districts manage the pathways, some routes in districts and alleys - The opeation center of anti-flood program manages the water drainage The management levels are so complicated and hard to indentify the duties and responsibilities 3.2.2 Construction technical management 3.2.2.1 Technical document management Document management is mainly manual, not applying information technology, when the number of records increases, there will be difficulties in managing and retrieving upon needed 3.2.2.2 Checking and monitoring the technical status of the project The patrol teams will inspect at of urban traffic management zones; Ho Chi Minh City Ferry Bridge Construction Company Limited; Saigon Traffic Construction Company Limited; Investment and Construction Management Board, urban management teams of districts, in coordination with the traffic inspection force of the Department of Transport have fully implemented, recorded damage but difficult to perform maintenance work due to lack of capital 3.2.2.3 Classification and assessment of technical status Yearly, the urban transport management sectors, construction management of districts will classify and evaluate the construction technical status, making periodic reports of constructions that cause dangers traffic, making recommendations for improvement, repair and maintenance But due to shortage of fund, it has been not very efficient 3.2.2.4 Documents of registration and records The constructions that are newly built, rennovated, improved, repaired are all registered and recorded at sectors of urban transport management and construction management of districts; due to high amount of documents so they are recoreded carelessly 3.2.3 The management and operation organization 3.2.3.1 The plans for ensuring the traffic safety, reducing congestion, flood and traffic accidents 14 - The plan of directing the traffic lanes to reduce congestion: they are done in some areas with high potential of congestion - Counting vehicles: they are done by Sai Gon transport construction company limited (01 time/year or 02 times/years) - Watching to ensure the traffic safety: they are done by sectors of urban management There are watching teams to stay alert 24/24 to response quickly to emergency situations due to natural disasters and other incidents - Monitoring and making analysis on traffic accidents, traffic safety and flood: the sectors of urban transport management, management center of Sai Gon river tunnel and traffic patral teams regulary co-ordinated with police officers to monitor, collect the information of traffic accidents, traffic congestion; making periodic reports to Department of Transport at every 5th date of the month 3.2.3.2 Management of the method to protect the work and road safety barriers Department of Transport regularly co-ordinates with the local authorities to set up landmarks; inspecting and checking, handling with bad behaviors creating damages to the works, traffic safety barriers, etc 3.2.3.3 Management of maintenance activities - Department of Transport carries out the activities of maintaining the road, bridge systems, installing the lane barriers, sign signals, light signals, etc maintain the quality of the works, ensuring the traffic safety - Carry out the activities to innovate the water drainage such as: gas tunnel, water collection tool, gas tunnel lids, etc to broaden the water flow, reducing congestion by trash, etc 3.2.4 The cost management and budget creation in exploitation of urban roads 3.2.4.1 The cost management As per the allocated budget, the management agencies will make the cost estimate, present to Department of Transport for verification and approval The structure of the budget estimate includes: costs for patrol activities – senitary; cost for regular repair-maintenance; other unexpected costs 15 The management agencies will clarify the bid packages to make the ground for the contract signing The costs for patrol activities – senitary will be identified 01 time for the whole year, the payment will be made fairly for 12 months The relevant agencies will examnine the requirements for Approval/Disapproval The disapproved sections will be deducted the costs and settled as per Decision No 1460/QĐUBND dated 27/3/2014 of People’s Committee of Ho Chi Minh City 3.2.4.2 The reimbursement of BOT projects Currently, in Ho Chi Minh city, there are 04 toll plazas in BOT model, in which there is 01 plaza under management of Ministry of Transport, the remaining 03 are managed by People’s Committee of Ho Chi Minh City 3.2.4.3 Inner-city traffic fees Ho Chi Minh city has not applied collecting internal traffic fees although such project has been proposed by Tien Phong Technology J.S Company to People’s Committee of Ho Chi Minh City However, such project has not been approved 3.2.4.4 Collecting advertisement fees on buses Department of Transport has organized the bidding to exploit the advertisement activities on 2,082 buses, which is divided into bidding packages (3-year term) with total value of VND700 billion However, very few bidders attended such bidding packages 3.3 The drawbacks, limits of the management of exploitation of urban road transport works in Ho Chi Minh city 3.3.1 Drawbacks, limits of the management of exploitation of urban road transport works in Ho Chi Minh city 3.3.1.1 The management model The urban road transport infrastructure in Ho Chi Minh City is invested and managed by many state management entities, creating the complex in duties, responsibilities in management 3.3.1.2 The management method Apply process-based maintenance management (MPB), which means paying attention to the implementation of each work item, demonstrating the following shortcomings: 16 - Maintenance: the maintenance activities are still regarded as minor construction projects, creating waste - Quality control: The urban traffic management areas and urban management teams of districts are responsible this (both as the investor and for quality control), this is a big gap of management - Traffic organization: there are still many shortcomings like spreading responsibilities There is no consistency in management, operation and responsibility, leading to traffic organization is always passive, causing congestion, loss and traffic accidents 3.3.1.3 Urban management mechanisms and policies - Appropriateness and response of the policy: still too slow, the document’s life cycle is short, not suitable to apply into practice Therefore, those documents cannot keep up with the urban movement - Urban planning management: The management of urban planning of Ho Chi Minh city is not appropriate, even there are some wrongdoing actions such as planning of Thu Thiem new uran areas The responsibilities are of People’s Committee of Ho Chi Minh city, the proposing agency is Department of Planning and Architecture, Department of Construction, etc affecting the exploitation of urban roads - Urban order management: The urban management is abandoned, wrongdoing action of invading the traffic paths, pedestrian areas, invading the channel, creating water flow congestion - The management of investment and construction of urban road infrastructure: The investment policies still expose to many issues, decreasing the attraction from potential resources Laws and relevant regulations are not complete, creating many issues during the implementation 3.3.1.4 The application of science and technology - Road maintenance work is still manual and out of date - Application of new technological solutions in road maintenance is slow and inconsistent - Legal system such as regulations, norm standards in the application of new technology has been incomplete 17 3.3.1.5 The budget for maintenance The budget for maintenance mobilized from the state budget of the city and from Road maintenance fund from the central government is not very stable; the budget allocation from the central gorvenment is slow; the payment has to go through many procedures; the disbursement process is slow; the city has not actively studied the plans to collect the parking fees; path using; urban internal vehicles etc to increase the fund 3.3.2 Consequences of the management and exploitation of urban road transport infrastructure in Ho Chi Minh City 3.3.2.1 Technical quality of construction There is a tendency to decline due to many reasons, causing public opinion to question the management responsibilities 3.3.2.2 Traffic congestion Fast urbanization, booming overpopulation and personal vehicles; public transportation is not appealing, the traffic satisfaction is low, so traffic congestion is unevitable 3.3.2.3 Invasion to traffic paths and pedestrian areas The status of invasion to traffic paths and pedestrian areas have been very complicated, the management is not efficient, creating serious congestion 3.3.2.4 Urban flood Heavy rain, high tides of rivers create flood too many internal routes, making the grounds, road surfaces and utilities systems are damaged, decreased, affecting the exploitation efficiency 3.4 Analysis and evaluation of factors affecting the management of exploitation urban road transport constructions in Ho Chi Minh city After researching and discussions with many experts, the author indentify 31 factors affecting the management of exploitation of urban road transport infrastructure which are of 07 groups: mechanisms, policies; urban characteristics; model, method of- exploitation management; science and technology development, maintenance budget; consciousness of users and impacts of climate change Likert ladder from to used to evaluate via choices: (1) not affecting, (2) very little affecting, (3) medium affecting, (4) much affecting, and (5) very much affecting 18 The data is collected through issuing 200 votes, collecting 200 valid votes The data after encryption is processed by the SPSS20 software, the procedure includes: descriptive statistics, assessing the confidence reliability of the scale through Cronbach's Alpha; evaluate the average and standard deviation of the scales Table 3.35: Result of average and standard deviation of groups of factors Standard Effect Criteria Sign Average deviation level Urban characteristics ĐT 3.41 0.96 Impacts of climate change KH 3.47 0.92 Mechanisms, policies CS 3.04 0.82 Model, method of6 MH 3.15 0.83 exploitation management Science and technology CN 3.82 0.62 development Maintenance budget NV 3.62 0.92 Consciousness of users NSD 3.67 0.75 CHAPTER 4: SOLUTIONS TO IMPROVE THE MANAGEMENT OF EXPLOITATION OF URBAN ROAD TRANSPORT INFRASTRUCTURE IN HO CHI MINH CITY 4.1 Viewpoint of perfecting the exploitation of urban road transport infrastructure in Ho Chi Minh City The transportation system of Ho Chi Minh City must comply with specific urban mechanisms and policies through Resolution No 54/2017/QH14 dated November 24, 2017, while developing a comprehensive and sustainable transportation system 4.2 The basis to propose the solutions -
