Legal Policy Towards The Transfer Of Function Of Agricultural Land In Ngawi District

Increased land use change is correlated with population growth in a given location. The process of changing the use of agricultural land from agriculture to other uses on some or all of the land area is known as conversion of agricultural land, and it typically has a negative influence on the environment and the potential of the land. The government needs to address the major issue of the change of agricultural land uses, particularly paddy fields to non-agricultural areas. The aim of this study is to ascertain the extent of land conversion in Ngawi Regency and the relationship between the phenomena of land conversion and the use of local laws there. An method known as descriptive qualitative is used in this investigation. Through the finding and narrative presentation of data, we shall interpret phenomena in this study. A conclusion that can be drawn from the research is that agricultural land in Ngawi Regency deteriorates year after year. This results from the development of communities, toll highways, and industrial areas on formerly agricultural territory. In Ngawi Regency, the execution of law enforcement in relation to land use changes has not been done adequately.

Cement-based concretes with low water requirements

Highways are one of the main elements of the infrastructure and economy of any state. It is well known that the state and level of development of the country's highways directly affect the main economic indicators – the gross national product, the price level, budget revenues, the level of employment, and others. When developing multicomponent binders, as a rule, a systematic approach is used. New binders are considered complex systems consisting of subsystems or elements, each performing its functions. The elements in the system are not isolated from each other but grouped in such a way as to ensure the practicality of the entire system. It should be noted that any changes in a single element or replacing one element with another usually lead to a change in the properties of the entire system. The elements of the system are interconnected, and the more versatile the connections, the more effective the system is. The researcher's task is to correctly select the elements of the system, considering their properties and contribution to the system's overall structure. Of all types of metallurgical slags, blast furnace slags are the most widely used in the production of building materials due to their leading position in the overall balance, their ability to acquire hydraulic properties during rapid cooling, and others.

Influencing factors of sustainable highway construction

The triple bottom line, which consists of the three pillars of the environment, society, and economy, must be balanced to achieve sustainable development. Integrating social, economic, and environmental aspects in construction projects is still a challenge. The construction industry tends to use non-renewable and unsustainable resources with energy values contained therein. One of the infrastructures that need to be considered in the concept of sustainable development is highway infrastructure. Highway infrastructure projects are quite complex because they involve a lot of resources, require a wider location, and significantly impact the community and the government. Environmental, social, and economic issues are just a few of the persistent issues that frequently surface during highway construction. Common environmental difficulties include water and energy consumption, road landscape issues, and wildlife conservation. Social issues are common in road projects and include issues with land acquisition, relocation, and worker comfort. Instead, bid prices and production costs that are elevated as a result of the usage of eco-friendly materials could cause economic issues. This study aims to investigate the TBL factors that influence the construction of sustainable roads and highways. A literature study is carried out by searching articles related to sustainable road projects. There are seven factors and 29 sub-factors for sustainable highway development, according to the literature review. Technology, project management, ecology, materials, government, community, and value system are the seven factors. These seven elements all contribute significantly, are interrelated, and are necessary for the realization of a sustainable highway.

The article covers the issue of development, approval, implementation and further use of a domestic stabilizing additive for the production of stone-mastic asphalt mixes. The prerequisite for the creation of such a project was the development of the latest technologies and road construction materials, both on the world and Ukrainian industry markets, as well as the annual growth in the need for such materials during the implementation of infrastructure projects. Based on the results of the work, it was established that the quality of the domestically produced stabilizing additive corresponds to the level of quality of similar imported goods, and its cost is somewhat lower compared to foreign analogues. The total period of implementation of this project is eight years, taking into account the time for: development and approval of the necessary technical and permit documents; launch of a production technological line; approval and introduction of a stabilizing additive; observation for 6-7 years of implemented objects in the first year of implementation of the material; implementation of new facilities using the developed stabilizing additive. The results of this work can be used during the implementation of future infrastructure projects for the restoration and development of public highways, both in terms of ensuring the availability of domestic materials on the domestic market, and in terms of supporting and developing the domestic economy of Ukraine at the appropriate level. Keywords: wastepaper, stabilizing additive, technical and economic indicator, cellulose fiber, stone-mastic asphalt mixes, stone-mastic asphalt.

Hybrid Annuity Model in Road Infrastructure Projects

Abstract: Hybrid Annuity Model has grown into popularity as a PPP model for development of highways since its introduction in 2016, after declined interest in PPP to revitalize the sector. The model is considered to have the best of both worlds, as it reduces the financial burden on concessionaire, by investment of 40% of the money during construction by government and return of 60 % of the investment by concessionaire in bi-annuity over a period of 15 year. This study's objective is to provide an evaluation of the hybrid annuity model used in road infrastructure projects by analysing the model's practical issues. Through an elaborate literature study model is understood in detail from the evolution of PPP in road infrastructure, need of new PPP model with evolution of Hybrid Annuity Model in road infrastructure, Changes in MCA documents, Process of Hybrid Annuity Model, Advantages and identified issues in HAM through various authors was understood. The study focuses on 32 case studies to identify the key factor that affects the outcome/performance of the project. Furth more, the identified issued was ranked on the bases of likelihood of their occurrence and severity through Relative importance Index. Identification key factors are a must to make recommendations to make the model more robust by addressing the major issues affecting the performance of the project

Оцінка залучення ресурсів міжнародних фінансових організацій для фінансування інфраструктурних проєктів в Україні

The article examines problematic issues of application of programs related to the formation and development of critical infrastructure by international financial organizations (IFIs) in the context of transformational processes, taking into account modern realities. An assessment of the current state of the structure of infrastructure projects financed by the resources of international financial organizations was carried out. The priority directions for the use of financial resources allocated by individual organizations were analyzed. It has been found that IFIs use various mechanisms and tools for providing assistance to states in the financial provision of infrastructure, and their resources are directed to cover capital expenditures from the state and local budgets, replenishment of budget funds for specific purposes. Financing of road, transport, energy infrastructure is carried out. The article emphasizes the fact that financial support of IFIs is provided for the development of municipal infrastructure, city transport, highways, railways, small and medium-sized businesses, implementation of renovation projects, etc. The need for more effective use of the resources of IFIs in financing infrastructure projects as an important element of the system of financial support for economic development and the construction and expansion of the relevant legislative framework, taking into account the state of war in Ukraine, is revealed. In order to determine the priority projects to be included in infrastructure plans, it is suggested to consider the possibility of applying in Ukraine the methodology of prioritization of infrastructure projects based on the multi-criteria evaluation of target indicators defined in state, sectoral or city strategies and programs, which was developed by the World Bank.

The Impact of East Coast Highway Development (LPT 2) on Socio-Economic Development Communities in the KETENGAH Region

The development of LPT 2 aims to improve the standard of living of the people from economic, environmental, and social aspects. In addition to being a link and convenience between the cities, it also helps to open new job opportunities to the local community. This study aims to identify the impact of LPT 2 development on the socio-economic development and well-being of the KETENGAH region community. This study used a survey type design to determine community perception of migration and mobility, the impact of Covid-19 on income, entrepreneurship, and community well-being. A total of 1,771 households and a total of 239 entrepreneurs were involved as respondents to the survey which was randomly selected from 5 towns in the KETENGAH region namely Bandar Al Muktafi Billah Shah, Bandar Bukit Besi, Bandar Ketengah Jaya, Bandar Seri Bandi, Bandar Ceneh Baharu while the census method was used for entrepreneurs as the purpose of the study had to involve the whole entrepreneur in the KETENGAH region. The questionnaire used in this study is taken from the study of the prospects of municipal development KETENGAH because of the construction of LPT 2. The survey findings show that the data distribution for each target group is different for each development core. There are some cores that are quite dominant for households and there are also dominant cores for entrepreneurs for districts, towns, mukims and villages. However, the data shows that the community or population in the MIDDLE region has the potential and ability to meet the needs of all cores at different rates. Implications of the study on policymakers (government), private sector, industry, and entrepreneurs in realising the impact of LPT 2 development on the socio-economic of the country and the local community. Several study recommendations were also discussed for improvement.

Research on the Multi-attribute Evaluation Model for the Investment Results of County-level Highways in New Urbanization

County-level highway, as a transport carrier to expand the external economic exchanges of rural areas, plays an important role as a hub in the rural road network system, and it is an important infrastructure for the country to promote the construction of new urbanization. In order to ensure the sustainable development of county-level highway, according to the relevant policies in China, the research on the investment effect evaluation of county-level highway projects has been regarded as a focus in the “14th Five-Year Plan”. Therefore, evaluating the investment benefits of the in-service county-level highways by identifying key evaluation factors has become an important research topic for new urbanization development. Since there is a lack of a comprehensive and reasonable evaluation index system. Therefore, this paper has taken the policy applicability and maximization of comprehensive benefits as the research goal, and started from five criteria, including new urbanization development ability, road network construction ability, economic benefits, social benefits and environmental benefits. Later, 14 second-level factors including industrial development ability, coverage of road network structure and national economic evaluation conclusion, etc., as well as a total of 58 third-level factors including the growth rate of the number of townships service industries and service industries, the increase of highway transport tools and regional urbanization growth rate, etc. were screened and constructed as the investment effect evaluation system. Subsequently, according to the characteristics of gray fuzzy of county-level highway indexes, this paper established a hybrid model applicable to the multi-attribute investment effect evaluation of new urbanization county-level highway, which used the game combination weighting method (GCWM), to combine the entropy power method and hierarchical analysis method to assign weights and reasonably calculate the comprehensive weights of indexes, and on this basis, it combined grey Euclid relational analysis method (GERAM) and the attribute theory to rank the correlation degrees of evaluation objects and further classify the investment effect level of the project. Finally, the hybrid model was applied to the county-level highway under the new urbanization construction demonstration counties to derive the optimal solution, as well as the optimization paths and measures for other auxiliary solutions. The results of this study provide an effective theoretical basis for the evaluation of the investment yield of rural transportation infrastructure with the support of policies, and provide a reliable practical method for the developing countries to achieve the maximum comprehensive benefits of the county-level highway investment programs with limited funds.

Integration Method for Web based Visualization Framework of Green Highway Index and Carbon Footprint Calculator

Global warming and the development of the green economy have imposed more pressure on government economies to de-carbonise their economic initiatives. This, along with the global financial crisis, has prompted a significant rethinking of digital solutions to monitor carbon emissions. Likewise, drawing investors’ investment to further development of green highways by digitised tools for infrastructure projects is crucial. However, there is a demand for integration and visualisation of green highways assessment tools, which highlights an important gap in developing data integration and web-based visualisation application. This paper presents a research proposal method to build an integrated web-based dashboard that monitors the green highway rating assessment and the Carbon Footprint. It emphasizes variables of Malaysia Green Highway Index (MyGHI) and Carbon Footprint Calculator (CFC). A framework for integrating and transforming towards visualisation of web-based dashboard is established. The integration of MyGHI-CFC to the digital level and create a web-based dashboard used different methodologies from mixed qualitative and quantitative research. The results of this integration and visualization foresee contribute to an effective example, paving researchers with effective tools and standards that will contribute to the development of the green highway and future sustainability projects.

A decision support tool for evaluating the wildlife corridor design and conservation performance using analytic network process (ANP)

A recent issue highlights the need for a wildlife corridor to mitigate habitat fragmentation and biodiversity degradation caused by intensive urbanization in the country, such as the development of infrastructure, roads, and highways. Indeed, the issues of frequent road and vehicle-animals collisions are ever-increasing in urban corridors. As a result, flora and fauna populations can become isolated, leading to an unbalanced ecosystem. This study developed the Wildlife Corridor Design and Conservation (WCDC) index, assessment model. The study has investigated the wildlife corridor design and conservation features through a systematic literature review, clustered them into three criteria (biophysical, structural, and environmental designs) and twenty-one sub-criteria. The study applied the Analytic Network Process method to measure the weights of features; habitat preservation (WC1.1 = 0.280), species varieties control (WC1.2.=0187), and conduit for movement (WC1.3. = 0.100) play critical roles in wildlife corridor design and conservation. The Weighted Sum Method verified the WCDC model through a case study (Red Earth overpass, Canada). The model assigns certification labels (Gold, Silver, Bronze, or not-certified); accordingly, it ranked the evaluated site as Gold, which means the Red Earth overpass performs intimately in biophysical, structural, and environmental preservation of mammal habitat. The study conducted regression analysis for model validation, determining a significant association between the base and case-study models.

Economic analysis of bicycle tracks using the HDM-4 model - case study for São Paulo city

In addition to technical studies, bicycle paths should be a product of planning and investment policies considering the ability of projects to generate socioeconomic benefits, implementing policie’s objective analysis relevant to the feasibility of projects for the implementation of exclusive bike tracks. In this paper the Non-Motorized Traffic (NTM) model of the HDM-4 (Highway Development and Management) software is applied for the analysis of different alternatives for bicycle lanes, evaluating aspects such as current and potential cyclists demand, operation speed, capital costs and economic profile of bicycle users. The combination of such variables leads to technical and economic alternatives whose analysis results relevant differences in their profitability indicators. The analyses were carried out considering two scenarios; the first comprises the analysis of the profitability of alternatives structured with normative guidelines that, in terms of speed, represent ideal operating conditions; the second scenario consists of a more realistic evaluation for the city of São Paulo, considering speed restrictions and diversifying the user profile according to the per capita income of the main regions of the city. The results reflect interregional diversity about the desirability of bikeway projects based solely on the monetary benefits of reduced travel times. The kern results point out financial risk of the projects as governed by speed and traffic, also requiring a demand of over 1000 bicycles/day and an operation that exceeds 8 km/h to support bicycle projects investments.

A Review on Work Zone Safety During Blackspot Improvement Construction Under Blackspot Management

Abstract: Massive Road building and development is being taken up in India, under various schemes, such as National Highway Development Project (NHDP) and Prime Minister’s Rural Road Development Schemes (PMGSY). Activities of improvement of about 45,000 kms of National Highways and around 400,000 kms of rural roads besides numerous urban roads are going on, all across the country. To ensure safety of all, there is a need to adopt an efficient and effective plan for management of traffic in work zones which are already blackspots. Work Zone Traffic Management Plans (WTMPs) are required to meet the safety needs of regular traffic as well as works traffic, ensuring minimum disruption in access to properties and movement of pedestrians. This research is a case study of road accident scenario on NH-152(Ambala-Zirakpur section). In 28.05 kilometers long stretch it has 24 identified accidental black spots, indicates that about 12-13 km of the road length has engineering faults and lack adequate infrastructure as per the requirements of the vehicles/pedestrians. This research talk about management of activities involved during its blackspot rectification work in work zone areas. As per this approach we have divided whole stretch into 5 corridors and described management of activities with main concern of safety, cost and time. At last, we have compared traditional approach of blackspot improvement and corridor approach of black spot improvement and finally concluded our study in form of guidelines which can be adopted during black spot rectification using corridor approach.

Implications of highway development and expansion on urban resident

This study examined the implications of highway development and expansion on urban residents in Dindigul city. Data was obtained from the administration of questionnaires to 50 residents of Dindigul city, who were randomly selected. Simple descriptive statistics and chi-square analysis were employed. The findings show that the traffic flow was found to be very smooth and free due to the wide and good condition of the highway; the residents stated that highway expansion allow increase in inflow of new residents, businesses and puts pressure on the existing houses thus there is increase in value of houses as a result of increase in demand; residents believe that the expansion of roads has opened up the area for more businesses which now causes high cost effect on rent and leases in the study area. The research suggests that all road designs, construction and rehabilitation work should be handled by competent engineers who must give guarantee on the roads for a specified period. The proper functioning of an urban area depends on an efficient transportation network; this contributes to the economy of India directly through influx of people.

Quantifying the photovoltaic potential of highways in China

Installing photovoltaic (PV) modules on highways is considered a promising way to support carbon neutrality in China. However, collecting the area of the highway, and precisely assessing the shadow area of the highway under complex terrain remain challenges. That severely hinders the assessment of highway PV potential.To address these challenges, a spatiotemporal model is developed in this study to estimate the annual solar PV potential on highways over the whole Chinese territory.First, the areas of different highway segments are calculated based on highway network and highway toll stations. Second, hourly shadow area on highways created by nearby terrain is estimated based on a digital elevation model (DEM). When calculating the highway PV potential, the solar irradiation received in these shadow areas is regarded as zero. Finally, the PV potential of all lanes and emergency lanes was estimated at the prefecture-level city scale using surface radiation data and radiation assessment models. Based on the highway data with a total mileage of 143,684 km at the end of 2020, the results show that the annual PV potential is 3,932 TW and that the corresponding installed capacity is 700.85 GW, which can generate clean electricity at a rate of up to 629.06 TWh. The annual PV potential of highways in the southeast is greater than that in the northwest owing to the higher highway density in the southeast. This study provides a reference basis for highway PV construction planning and suitably assessment in each region of China for PV highway development.

Assessment of vehicular fuel consumption and interaction with pavement characteristics using HDM-4 on Indian urban road network: A case of Pune city

Rapid urbanization and exponential increase in the number of vehicles on city roads have triggered issues like air pollution and accidents, endangering the health of millions of people in Indian cities. Vehicular emission is a major contributor to air pollution in Indian cities. This study primarily analyzes the relative effects of riding quality and pavement surface type on vehicular fuel consumption (FC) in an urban environment. This study utilizes the Road Asset Management System (RAMS) applications to predict FC in different scenarios of pavement maintenance. Highway Development and Management (HDM-4) software was integrated into RAMS for network & economic analysis and FC prediction of the road network. The study was conducted on the Pune city road network in India, and the results revealed a 2.32 % reduction in fuel use if timely maintenance is provided. Over 0.128 million liters of fuel per 1000 vehicle-km can be saved over the study network of only 36.5 km over the next 15 years, equivalent to US$ 155,206.18 in 2021. The analysis of covariance test results showed the significant effect of pavement surface type on fuel consumption, with 4.86 % less fuel consumed on cement concrete surfaces than bituminous surfaces. About 99.431 liters per 1000 vehicle-km of fuel were utilized by the vehicle fleet on concrete pavements, while 104.513 liters per 1000 vehicle-km of fuel were consumed on bituminous pavements after adjusting for roughness characteristics of both the surface types.

Optimum axle load limit on the trans west African highway – a case study of Ghana’s coastal corridor

The Economic Community of West African States recently reviewed regulations on axle weights. Ghana rolled out its new regulation in January 2014. The allowable axle weights in the new regulation are much stiffer (e.g., the allowable single axle limit is now 11.5 tonnes compared to 13.5 tonnes, previously). Regional freight haulers contend that the new regulations make Ghana’s corridor less attractive to trade. However, the road agency sees it as a way of maintaining and extending road pavement life. The goal of this study is to find the optimum axle limit that is economically feasible to create a balance between road preservation and port competitiveness. Data collected on 47,959 individual trucks from July 2010 to December 2013 were analyzed. A calibrated Highway Development and Maintenance model for Ghana was used to estimate the total transport cost. The analysis showed that 19 % of trucks were overloaded, and footwear was the most frequently overloaded commodity. Overloading was common with all trucks, but 3-axle trucks experienced the highest extent of overloading. It was found that if the road agency maintains a high road maintenance standard (e.g., International Roughness Index = 3 m/km), then the optimum axle limits will be from 12-13 tonnes, 20-22 tonnes, and 28-29 tonnes for single axle, tandem axle, and tridem axle, respectively. However, at a low maintenance target (IRI = 7 m/km), the optimum limits need to be 12.5 tonnes and 18-19 tonnes for single axle and tandem axle, respectively, while the optimum tridem limit remains unchanged.

The socio-economic and cultural impacts of the Pan Borneo Highway on Indigenous and local communities in Sabah, Malaysian Borneo.

Road and highway development can provide multiple benefits to society, but without careful planning, this development can result in negative social and environmental impacts. The 1,200 km Pan Borneo Highway project (PBH) in Sabah, Malaysian Borneo, is constructing new highways and up-grading 2-lane roads to 4-lane highways. We assessed the potential impact of the PBH on communities using three width scenarios of 50m, 75m and 100m for planned highway alignments, and identified potentially impacted dwellings and community lands. We estimated that 65–93 villages will be impacted, and that 1,712–7,093 dwellings and 3,420–6,695 ha of community lands (e.g. paddy, oil palm smallholdings and rubber) may be lost to the PBH. Due to land tenure technicalities, many affected households may not get compensation for the loss of their homes and lands. The PBH will disproportionally impact Sabah’s Indigenous Peoples, with the Kadazandusun most affected. For this study to be constructive, we provide a low impact alternative alignment for a part of the PBH; discuss the socio-economic and cultural impacts of the PBH, and offer some perspectives on current planning procedures in Sabah to support more sustainable and equitable development.
