Various studies have been carried out on urban dual-carriage ways and its implication on sustainable development in different parts of world. In Nigeria, work on dual carriageway for sustainable development still remained under explored. This study therefore, focused on urban dual carriageway for sustainable development of Ado- Ekiti and to enhance good quality of life of the people. Data for this study were obtained from primary and secondary sources as well as field observation.250 copies of questionnaire were administered in 5 purposively selected areas in Ado-Ekiti with the use of questionnaire. Simple random sampling method was used to choose 30 houses at an interval of 10 houses through balloting .Secondary data were sourced through journal articles and edited books. Data were analyzed using both descriptive and inferential statistic techniques. Chi-square statistical method were adopted to test the two hypotheses stated (i) effect of dual carriageway on socio-economic activities in the area and (ii) the impact of dual carriageway on travel time and cost of transport in the area at 5% level of significance. It was discovered that dual carriageway has great influence on socio - economic activities, trip generation, travel time, cost of transport among others in Ado- Ekiti

International Journal of Sustainable Development & World Policy, 7(1): 8-26. DOI: 10.18488/journal.26.2018.71.8.26
The purpose of the study was to investigate the causes of railway infrastructure failures in the case of Transnet Freight Rail’s Steel and Cement business unit and suggest methods to increase the reliability of the business unit’s railway infrastructure and recommend policies to increase the reliability of the railway infrastructure., A reliable railway infrastructure will grow the market share of the business unit, reduce operating costs, grow the economy of South Africa, create employment, and increase the revenue of the business unit. A quantitative approach was used to conduct the research and questionnaires were distributed to a population of 1048 employees that work for the business unit with the participants chosen based on their railway infrastructure experience and railway exposure. The study revealed that extreme weather conditions, ageing railway infrastructure, vegetation, lack of maintenance, other Transnet departments, poor railway infrastructure maintenance, theft and vandalism, are the major causes of railway infrastructure failures in the business unit. The research made a number of recommendations including that the business unit develop a lifecycle management program for its ageing infrastructure and introduce skills transfer programs in place. Railway maintenance was suggested as being a key performance measure.
The paper's primary contribution determined that management needs to improve on asset protection and security measures and controls, as neglected these can lead to substantial financial forfeiture and loss of life. The study identified the inadequacy of current security measures and makes a number of suggestions to alleviate loss.
Determinants of Rural Residential Solid Waste Collection Services in Lagos State
Olatomide.W. Olowa (2018). Determinants of Rural Residential Solid Waste Collection Services in Lagos State. International Journal of Sustainable Development & World Policy, 7(1): 1-7. DOI: 10.18488/journal.26.2018.71.1.7
In the wake of increased investment in and new policies regarding Residential Solid Waste Management (RSWM) in Lagos state and the attendant consequence of inefficiencies currently observed with the system, this study describe the state and determinants of waste management services in rural Lagos State. A well-structured questionnaire, which consist of two sections, was used to elicit demographic and residential solid waste collection information from 200 household heads sampled using the multi-stage sampling in 3 Local Council Development Areas (LCDAs). Data were analysed using both descriptive and Dprobit, an advanced probit logistic model. Results show that the mean and standard deviation for whether a ward/neighborhood has RSW collector was 0.23 and 0.42. Similarly, mean and standard deviation for Private Sector Participation (PSP) operator employing RSWC workers was 0.22 and 0.41. Among demographic and residential solid waste collection characteristics, income, population, PSP charges or rates and distance to dump site are found to be determinants of RSWC services in rural areas of Lagos state. The analysis shows that a one thousand increase in Mean income would increase the possibility of providing waste Transportation services by 0.20 percent and the possibility of employing waste workers by only 0.17 percent. Conversely, a one Kilometre increase in distance to dumpsite would reduce the possibility of PSP operator acquiring a compactor. Government incentivisation of rural residential solid waste collection would go a long way to eliminate poor RSWC in rural areas of Lagos State.
