Financing road network life-cycle costs on sustainable basis is one of the most crucial challenges facing many developing countries, as it requires a thorough awareness of road network costs and available sector funds. This thesis has developed a pragmatic cost-revenue model for estimating road network life-cycle costs and available road sector rev...

One of the important assumptions and factors of social and economic development of countries and their regions is road infrastructure. This is particularly true in countries where road transport is the largest component of overall transportation, such as in Slovakia and Poland. Road infrastructure as part of the transport infrastructure is here reg...
For several decades now, the decentralization of policy authority to local officials has been a key component of development strategies around the world–emanating both from developing country governments themselves and the international development community as well. After more than thirty years of these efforts, we still have no clear consensus co...

... If the quality of a highway project does not meet the required level, the need for maintenance and repair works increases, which causes delays in traffic and transport flow, leading to increased losses and slower economic growth (Thurner, 2001). The efficiency of road transport systems in developing countries (such as Ghana) is frequently restricted by operational and maintenance costs because of their poor road conditions (Amoatey, 2007). Roads are important national assets that must be preserved (Amoatey and Ankrah, 2017;El-Hamrawy et al., 2017). ...
Purpose
There are various methods to assess the failure of a road construction project that does not meet quality and performance standards. This study aims to evaluate the factors affecting the quality management of road construction projects in Indonesia by identifying the critical challenges in implementing quality management processes and examining the countermeasures to address these problems.
Design/methodology/approach
In this research, the quality management processes in Indonesian road construction projects are evaluated using a mixed quantitative and qualitative approach. Quantitative data obtained from two rounds of Delphi questionnaire surveys as the primary data source, and focus group interviews as the qualitative data are used to achieve the aims of this study.
Findings
It is found that from as early as in the preconstruction stage of a project, the availability of quality standards and documentation is problematic when implementing quality management processes. The critical factor of the quality control activities of a project and the quality management roles and responsibilities of the stakeholders during road construction is the project team. This constraint deals with the interaction of the competency, commitment, and mutual cooperation among the main stakeholders to ensure that quality management processes are implemented. This implementation is a part of controlling the road pavement materials, supervising the project activities according to a specified standard, and reporting the project performance. The findings of this study add parameters relating to quality management and quality processes in a road construction project area.
Originality/value
This study is the first to evaluate the quality management processes in the construction of Indonesian road projects. The investigation identifies and evaluates the causes of the persistence of poor road quality. All revealed constraints are substantial factors that hinder the implementation of quality management processes when delivering quality road products. This study addresses the key influencing factors and scenarios related to quality management during road construction projects in Indonesia and other developing countries as practical examples and provides case-based insights for construction practitioners and civil engineering academics in developed countries.
... This means that without efficient transport infrastructure in place, economic and social development would be severely hindered. Amoatey (2007) confirmed that, despite the importance of roads in the promotion of overall economic development and improvement in living conditions, efficiency of road transport systems in many developing countries (such as Ghana) is often constrained by high vehicle operation and maintenance costs due to poor road conditions. ...
Purpose
The purpose of this paper is to investigate the causes of road construction delays in Ghana and identify appropriate mitigation measures.
Design/methodology/approach
The initial approach involved an empirical analysis of 48 road projects to quantify the extent of time. This was followed by a survey of the perception of road agency and donor partner officials of the critical causes of road project delays.
Findings
About 70 per cent of road projects experience delays and 52 per cent experience cost overruns. The average time overrun and cost overruns of road projects in Ghana was 17 months and US$1.15m (or 22.5 per cent), respectively. The five most critical causes of road construction delays were delay in finance and payment of completed work by owner (client-related); inadequate contractor experience (contractor-related); changes in scope by the owner during construction (client-related); delay to furnish and deliver the site to the contractor (client-related); and inflexible funding allocation for project items (donor-related).
Research limitations/implications
The most critical constraint of this study is the fact that findings are based on only the views of industry professional experts. It may be assumed that despite using broadly used terminology to refer to the causes of project delays, the interpretations by respondents may have differed from those intended. Further research could look at the correlation between time overrun and cost overrun using principle component analysis.
Practical implications
The identified delay factors are not unique to the road sector. From both academic and practical perspectives, the results emphasizes on the need for a holistic and integrated risk management model for the entire construction industry in Ghana.
Originality/value
The paper examined the causes of road project delays in the Ghanaian context and recommended remedial measures.
... Infrastructure instead of NPKL has strong and quick effects: good roads and rail lines are the main link between regions and have a significant impact to reduce the costs and improve the trade of goods; it certainty can help farmers to leap from subsistence agriculture to cash crops trades (Amoatey 2007). ...
Nowadays, agricultural prices are highlighted combined with, as alleged collateral effects, hunger and malnutrition in Sub-Saharan Africa (SSA). However, today, SSA has around 47,5 percent of rural population in extreme poverty and between 1990 and 2005 when the food prices was stable and with low prices, extreme poverty in SSA involved around 64.6 percent. We assumed that the undernourishment or starvation continued in SSA because there the misery persisted. Poverty reduction is the only way to the end the hunger in Africa. Also, for an agricultural country in SSA – without significant mineral resources – the best way to solve the problem of poverty is through agricultural development. Our sample are nine countries in SSA – Burundi, Ghana, Malawi, Mozambique, Rwanda, Uganda, United Republic of Tanzania, Zambia and Zimbabwe – the so called SSA – 9. Thus, we built up a recursive model that answered how the agricultural gears in SSA – 9 were moving between 1990 and 2005, as well as assessed how the agriculture could reduce rural poverty. As a result we saw that the main tools that had a strong relation with poverty reduction in SSA – 9 are some policies implications as; property rights, access to the credit system, human capital and infrastructure.
