Abstract
Roads are a crucial part of modern life, serving as the primary means of transportation for people and goods. The relevance of roads to life and its activities cannot be overstated, as they play a vital role in connecting communities, facilitating economic growth, and enabling access to essential services. This research project aims to explore the multifaceted impact of roads on various aspects of life, including social, economic, and environmental factors. One of the key aspects of the relevance of roads to life is their role in promoting social connectivity and cohesion. Roads provide the physical infrastructure necessary for people to travel and interact with one another, fostering social relationships and community engagement. In rural areas, roads are particularly important for connecting isolated communities and enabling access to education, healthcare, and other essential services. In urban areas, roads facilitate the movement of people and goods, supporting vibrant economies and cultural exchanges. From an economic perspective, roads are essential for trade and commerce, enabling the movement of goods to markets and opening up opportunities for businesses to grow and expand. Well-maintained roads can reduce transportation costs, increase efficiency, and attract investment to areas that are well connected. Conversely, poor road infrastructure can act as a barrier to economic development, hindering businesses and limiting access to job opportunities for residents. Furthermore, the impact of roads on the environment cannot be overlooked. The construction and use of roads can have significant environmental consequences, including habitat fragmentation, air and noise pollution, and increased carbon emissions. It is essential to consider sustainable road development practices and explore ways to mitigate the environmental impact of roads through measures such as green infrastructure, wildlife crossings, and eco-friendly construction materials. In conclusion, the relevance of roads to life and its activities is undeniable, with far-reaching implications for society, the economy, and the environment. This research project aims to shed light on the various ways in which roads influence our daily lives and to highlight the importance of sustainable road development practices in ensuring a more connected, prosperous, and environmentally friendly future. By understanding the significance of roads and their impact on different aspects of life, policymakers, planners, and communities can work together to build a road network that meets the needs of society while preserving the natural environment for future generations.
Project Overview
1.1 GENERAL INTRODUCTIONThe relevance of road to life and its activities cannot be over emphasized.Road is as old as the origin of man and plays a vital role in the life of the people in communities, states, countries. It is quite obvious that life would have been very difficult without the existence of roads. Nigeria for instance acknowledged the importance of road such that the local, state and federal government are all involved in the development and maintenance of road network.History has shown that provision of roadway is a necessary tool for civilization. It advances prosperity increase and this bring about demand for better and faster communication facilities especially roads.The continuing increase in Nigeria’s population has made the daily movement of passengers and goods an increasing complex problem.1.2 RECONNAISSANCE SURVEY This is a quick type of survey or a rapid examination of the ground and its adjacent natural features usually made without survey instruments to limit the alternative routes in terms of cost to one or two.The following factors are normally considered in reconnaissance survey.ï¶ Overall cartage of goodsï¶ Nearness to road materials quarriesï¶ Traffic conditionsï¶ Soil conditionsï¶ Right of way or road landï¶ Ruling gradientï¶ Type of road surfaceï¶ Number of major and minor bridgesï¶ Approximate length and costï¶ Curvative along the alignmentThe road under consideration (A by pass from IMT/ Federal Secretariat road to Industrial center and Mass Communication Department) has been graded and motor drivers and pedestrians use it. On the sides of the proposed road are existing buildings and farm lands.The traffic capacity of the road is low because of the poor grading of the road.Because the road has not been properly paved, less pedestrians use the road and motorist prefer going through the longer way by passing through mass communication department when going to industrial center.When the road is properly improved, all these problems will be eliminated and a lot of benefit will be accrued, benefit to the intending business center as a result of more people using the road and reduction in travel time.1.3 GEOMETRIC DESIGNThis is the aspect of the highway design that is solely meant to take care of the road user and level of service rendered to him. The paramount factor of consideration included expected traffic capacity, design speed and volume. O’ Elaharty E. A in his book -Highway Traffic Planning and Engineering†states that proper geometric design will inevitably reduce the number and severity of highway accidents while ensuring high traffic flow with minimum delay. He continued by saying that improper design would result in the early obsolesce of the new highway with constant economic loss to the community.1.4 FACTORS INFLUENCING THE CHOICE OF STATIONa. Easy Measuring Condition: Stations were chosen to avoid obstacles during drainage or tape exercise.b. Intervisibility: Station were chosen and placed such that the station does not obstruct the other station line of sight.c. Tranversing at closed Distance should avoided: This is to avoid angular error that would be introduced there to target at short range not be properly bisected.1.5 FACTORS WHICH FAVOUR THE SELECTION OF ROUTE OR ROAD ALIGNMENTThere are several factors which normally favour the selection of a route alignment for high way construction.i. The route should be as straight as possible. This implies less cost of construction, maintenance and operation of vehicles as wear and tear on curves route are entirely eliminated.ii. Vertical and horizontal elignment should be eased out with maximum radius of curvature in relation to the design speed and maximum route of superelevation.iii. Good sight distance should be maintained. Sight distance or visibility is the distance measured along the center line of the road over which the driver can see the opposite object on the road for necessary application of brake.iv. Applicability of proper road drainage: Immediate evacuation of rain water on pavements as well as embarkment of a highway is necessary is to last till the end of the design life generally taken as 20years.v. Availability of road building materials such as stone, gravel, sand, laterite etc along the highways bring down the cost of the construction as well as maintenance cost.vi. Good formation soil should be ensured.1.6 AIM AND OBJECTIVE OF THE PROJECTThis aims at giving student practical knowledge in the design of a roadway in order to aid her in designing a related project in real practice in future.1.7 SCOPE OF THE PROJECTThe scope of this project includes the leveling, theodolite traversing of the road, design of the curve, soil investigation and pavement design of the route of study.
