The research examined the application of geographic information system in road transport infrastructure maintenance (a case study of Ogun state). The survey research was used in this study to sample the opinion of respondents. This method involved random selection of respondents who were administered with questionnaires. Relevant conceptual, theoretical and empirical literature was reviewed. The target population of the study comprised selected residents in Ogun State, Nigeria. The questionnaire administered was three hundred and ten (310) copies and three hundred copies (300) retrieved which constitute the sample size. The descriptive and analytical approach was adopted using Chi-square to test and analyze the hypotheses earlier stated. The result revealed that there is a significantimpact of geographic information system (GIS) on road transport infrastructure maintenance. The finding of the study also reveals that Geographic information system (GIS) helps in visualizing locations with high numbers of accidents in Ogun State. The findings of the study also reveal that there is a significant relation between geographic information system and road infrastructure maintenance. The finding of the study also reveals that Geographic information system helps the ogun State government to facilitate high way maintenance. The findings of the study reveal that. It was therefore concluded that geographical information system plays a crucial role on road transport maintenance and management. It was recommended that the government of Ogun State should adopt the geographic information system so as to be able to regulate the alarming accident and traffic congestion in the State.
CHAPTER ONE
Background of the Study
The foundation of the road transport infrastructure management system is the idea that the road network is an asset that needs to be upgraded and maintained in order to ensure the best performance, the best value for the money, and the longest possible service life (Musa, Richard &Iguisi, 2015). They continued by stating that the goals of road managers are to allow the network and surface to withstand wear and tear damage, to prevent substandard conditions from developing, and to ensure that traffic can continue to move in a manner that is safe, efficient, reliable, and causes the least amount of environmental damage possible.These objectives are accomplished by a number of works and activities, the management of which depends on the upkeep of current knowledge regarding the characteristics and surface condition of the road network.
In an ideal world, this study would use a variety of cutting-edge technologies to automate the use of this information system. Due to the complexity of this kind of system, integration as well as security and data sharing considerations are required. Building an information system to fulfill the constantly rising social, economic, and environmental demands placed on our road transportation infrastructure depends on addressing these problems and needs (Rasdorf et al., 2000). Rasdorf et al. (2000) noted that the infrastructure departments of Portuguese municipalities, such as Lisbon, Coimbra, Oliveira do Hospital, Oliveira do Bairro, and others, manage their infrastructures by utilizing a number of systems or programs maintained by various divisions inside the department of infrastructures. Each system or program creates and keeps track of a sizable amount of data in distinct databases. Many of these data are processed, analyzed, and shared/used in various formats by various divisions. All information on governmental facilities includes a spatial component.A highway corridor, a linear feature like a road, and a point feature, such a sign or the scene of an accident, are all represented by that spatial component. Historically, the departments of infrastructure have not been able to use or share data as widely or as easily as they should be able to thanks to the current municipal databases and data management system design. Thill (2000) emphasizes the needs for GIS in transportation applications as well as the primary research areas in transportation that make use of GIS for "research, planning, and management" (referred to collectively as GIS-T).He offers a classification, just as Goodchild, but focuses more on how to use GIS to manage massive amounts of transport data than on the other factors. Thill claims that (200) GIS-T requires a data management system (whose goal is to make it easier to maintain and integrate inventories of transportation infrastructures held by public authorities), data interoperability (to allow transportation data sharing among various agencies, each with its own data base), real-time GIS-T (for real-time geo-referenced data storage, retrieval, processing, and analysis), large data sets (which involve the optimization of o (to allow the spread of GIS-T data over users and community, by means of web services).At the beginning of this decade, determining the primary transportation sectors where GIS could contribute and how was a significant problem. However, GIS have made fast improvements in recent years, expanding and becoming systematic throughout the scientific world. This is due to both the rapid advancements in technology and computation as well as the growing interest from public academic authorities. GIS technology is being used in a variety of transportation-related fields, according to ESRI, including high-speed rail and road infrastructure management, international shipping, airport management, fleet logistics, traffic management, and intelligent transportation systems (ITS) (2003).The variety of applications that can be created for the transportation systems of various transportation companies is greatly facilitated by the breadth of the field of GIS and transportation system integration. Curtin (2003). Infrastructure management is a strategy that both public and commercial organizations have used to keep their assets in good and usable shape at the lowest possible cost. However, as the majority of the country's infrastructure systems matured and the demands placed on them began to quickly rise in the middle of the 1960s, infrastructure agencies began to concentrate on a systems approach for managing infrastructure. The Asset Management idea of today is the result of this process.The procedure began with the creation of pavement management systems (PMS), continued with the development of bridge and infrastructure management systems (IMS), and lately advanced into asset management (Ferreira &Flintsch, 2004).
An infrastructure management system, according to Ferreira and Flintsch (2004), is a set of administrative tools that facilitates the systematic, coordinated planning and programming of investments or expenditures, design, construction, maintenance, rehabilitation, renovation, operation, and in-service evaluation of physical facilities. In order to provide and maintain infrastructure at a level of service that is acceptable to the general public or owners, the system contains the methods, procedures, data, software, policies, and decision-making tools required. Our road transport infrastructure must be effectively modelled using some type of information system before we can design, build, manage, and maintain it. (Hall, 2004) The operation of the road administrator's managing the road transport information management system must be considered as any other operational activity.The advantage that a GIS-based system can provide in terms of better managing the road transport network and infrastructure would be lost if this component of its functioning is disregarded. Road traffic accounts for well over 90% of all passenger and freight traffic in the nation, and as such, it is by far the most important form of transportation for Nigeria's economy (Transport Research Board, 2004). Road surface Management Information System is a requirement for successful management of road transport since a well-maintained road transport asset is very vital for the economic development of the country.For planning, engineering, asset management, and operations related to every mode of transportation at all levels of government and administration, geospatial data serve as the foundation (TRB, 2004). GIS have become one of the most effective tools to support transportation studies and applications because of their seamless relationship with space and location and given that their primary goal as a tool is to store, retrieve, and facilitate the analysis of spatial data (Goodchild & Janelle, 2004). The usage of GIS in the transportation sector is one of the many that is expanding the fastest. Rodrigue and colleague (2006). The classifications made by Goodchild and Thill were examined by Shaw and Rodrigue in 2006.They believed that GIS-T studies can be divided into three categories: applications, analysis and modeling, and data representations. Knowledge of GIS-based Road Transport Surface For the asset management and transportation departments, information management, effective use of geographic information, and awareness of their advantages are essential to planning and decision-making. It is based on this background that the present study seeks to examine the application of geographic information system in road transport infrastructure maintenance (a case study of Ogun state).
The world is becoming more and more urbanized, which has led to a number of issues with the environment, the climate, resource consumption, and public health. These issues are closely related to urbanization's negative effects, such as sprawl, congestion, the affordability of housing, and the loss of open space. Various layers of spatial planning and decision-making need to handle these issues. The linkages between land use, transportation, and the environment, for instance, should be given special and detailed study in urbanization management. Two distinct but connected challenges, urban structure and dynamics, are at the core of urban problems. From both a physical and socioeconomic vantage point, both difficulties are observable(Jiang & Yao, 2010). It has thus been harmed by carelessness that has caused road infrastructure failure. Road maintenance efforts have angered users since, after being repaired, the roads nearly immediately develop new potholes. Even worse, road upkeep has proven to be sporadic, which renders the transportation system inadequate. Therefore, it is necessary to coordinate activity sectors for economic development, and there are frequently competing interests. Transport is a significant activity sector in the services industry, and the services' transport component includes road, rail, and air transportation as well as other types of transportation(CBN, 2009). According to Luyimbazi's (2007) research, data on road inventory, condition, and traffic may all be efficiently gathered and managed utilizing geographic information systems (GITs).It based on this backdrop that the present study seeks to examine the application of geographic information system in road transport infrastructure maintenance (a case study of Ogun state).
