ROAD CONDITIONS IN GHANA

             Driving in Ghana can be a very enjoyable experience in some parts of the world but it can be a death trap in some nations. Ghana for one seems to be an example of the latter nations. One of the first spectacles that strikes any visitor to Ghana is the condition of the roads and heavy traffic especially in Accra. The main roads connecting the many other cities to Accra and circles such as the Nkrumah, J.B Danquah, Obetsebi-Lamptey and Ako-Adjei circles are in fairly good condition. However as soon as one turns from these main highways into the residential areas such as East and North Legon and Cantoments, one is greeted with a few good roads and many others with potholes several feet wide and deep even in these high income areas.

            On the other hand, in places such as Dansoman, Madina, Adenta and Ofankor, this is a nightmare. During the rainy season especially during the latter part of June, drivers are faced with the problem of not knowing how deep these potholes on roads now filled with water are. Drivers just hope that the pools of water in the roadways are not too deep to swallow their vehicles and as such throw caution to the winds and just drive through.
        
           The use of gravel then comes as a solution to help cover up potholes and also to surface new roads.This however leads to flying gravel stones smashing windscreens of oncoming vehicles and thus needs to be seriously considered. For a country that does not manufacture vehicles of any kind but rather has to rely on importation of both vehicles  and vehicle parts, the economic impact of broken vehicle parts is an enormous one.

          Another consequence of the road condition described above is that dust is blown into the air by vehicles using these exposed roads which have not been surfaced. This in turn may lead to the outbreak of asthmatic conditions in people and other respiratory diseases. This consequence is also contributed to by smoke emissions from the many vehicles plying the city roads.There are apparently no laws regulating vehicle emissions in the country and if there are, there is no enforcement of these laws.

           In other words not only is the economy hurting from these conditions but the health of the population is also at risk. As if the never ending condition of roads in Ghana is not bad enough, there does not seem to be any kind of traffic management in most places.Many of the road intersections, be they T- or four-road junctions or approaches to the circles, do not have traffic signals or traffic officers managing them. The result is lots of yelling, horn honking, no vehicles moving, and precious time lost.I believe that these conditions described above did not emerge just yesterday. The attitude unfortunately seems to be that this is how things are and have been and therefore they are acceptable. It is not acceptable and government should be held responsible.

ROAD ACCIDENTS

                 The sight of ambulances and police cars racing to the scene of a road accident in the city or on a busy highway is becoming so common in modern countries that few heads now turn even in idle curiosity.This is part of the tragedy of  road accidents. They occur so often that they are taken for granted and the public has grown accustomed to them. A fire outbreak, murder or riot is still  front page news. A serious motor accident resulting in gruesome injuries and loss of lives however gets a small back page paragraph, except to the relatives of those involved, whose lives maybe shattered and reduced to pitiful sadness, often poverty.

           Road accidents have become one of the leading causes of deaths in Ghana and the world. Efforts by government to reduce road accidents have been coupled with road safety awareness and education. Although it has helped in away it has not totally curbed this menace because of its increased occurrences. Statistics from the National Road Safety Commission revealed that there were 19 fatalities per 10,000 vehicles in 2010. In 201l, 2,330 road accidents were recorded bringing it to an average of  7 accidents per day across the country. By November ending in 2012, 13,535 crashes had been recorded resulting in over 2,069 deaths in Ghana. In December 2012 alone, 246 people died and 1,260 were injured in car accidents. According to the commission, the major cause of road accidents in Ghana was attributed to over-speeding which accounted for 60% of car crashes in the country.

            Furthermore, while some Ghanaians attribute road accidents to some superstitious and religious beliefs, to the Road Safety Management Services, the major causes of road accidents in Ghana are over-speeding, poor driving skills, talking on mobile phones while driving, broken down vehicles on our roads, fatigue driving by long distance drivers, drunk driving, ignoring road markings and signs. These reasons without any shred of doubt are all credible facts accepted by all. Over-speeding accounts for most of the causes of road accidents daily. This happens when drivers deliberately drive above regulated speed limits either to show off, meet deadlines or just for fun. In doing so, they put their lives and that of many other road users at risk.

                The inability of some drivers to understand or obey road signs is also another factor. Following appropriate rules such as road signs and traffic lights when one reaches intersections or hills will help save lives. Driving under the influence of alcohol slows down reactions and in most countries, the penalty for this is great. It is fatal to drive under the influence because a small quantity is enough to make one loose control behind the wheels. Since they say prevention is better than cure, it is essential for drivers to adhere to this regulation in order to prevent road accidents and loss of human lives

                The consequences of road accidents over the years have proved to be very dire and devastating to victims and those affected. It leaves a lasting on many with bad aftermaths of road accidents such as loss of lives, amputation, regrets, financial breakdown and most of all everlasting pain. No solution of the problem no matter how much efficient and needed can erase the pain and help these individuals who have been affected greatly due to road accidents in one way or another.

INVESTING ON ROADS, HIGHWAYS AND PUBLIC TRANSPORTATION.

           In this modern society, governments are always confronted with the dilemma of whether to spend more money on improving roads and highways and public transportation systems. This problem is a much debated one in the sense that it affects everyone in the society in one way or another in their daily lives. It is then quite rational for people in a society to choose investment on better roads and highways for the obvious reason that better road conditions would increase more public vehicles and accelerate the speed of them. If  a government however finds itself in the stage of defining its priorities, it should consider that there are many advantages in investing on roads and highways.

         The most important advantages of investment on roads and highways include higher potential for the transportation of goods, reduction in costs related to problems caused by low quality roads and a notable effect on the thriving of the whole region and the country in general. If governments invest on roads and highways, the quality and quantity of roads and highways in their various countries will increase. This will in turn improve the transportation of goods in regions which will eventually result in the booming of the economy and thus higher income for the government.

         Furthermore problems such as accidents and gradual damages to vehicles that are caused by low quality roads and highways will be reduced. Roads and highways will now be safer and fewer damages will be caused to vehicles and drivers. Finally a country with vast number of high quality roads and highways is more apt to prosperity. This is because there will be more opportunities for the people of the country to have access to various resources. Hence if the system is organised and managed well, it can lead to greater development in a country

           However there are also many advantages in investment in public transport facilities. A well designed and managed public transportation system can reduce traffic congestion in cities. Less traffic problems means the less air and noise pollutions and can provide people in the society with a better physical and mental health. In addition, prosperous public transport can save valuable time that is otherwise wasted in heavy traffic. Investing in public transport facilities can also lower the huge amount of costs consumed on private vehicles including fuel, service and insurance costs.

BENEFITS OF ROAD TRANSPORT

               Road transport is among the most important factors affecting the living conditions of people in the society. A proper road transport system has different components among which the roles of public transport facilities, highways and roads are prominent. Thus, a good road transport system assumes a special significance as it does not only impact on the overall quality of roads in a country but also influences greatly the economies associated with its construction and maintenance.

               The impact of road transport  systems can therefore have both positive(benefits) and negative(challenges) effects on the environment and the economy as a whole. Narrowing our focus to the positive impact of improved road transport systems on our economy, there are many advantages associated with an improved and proper road networks and also public transport facilities. To begin with, road transport systems connects places very well. Unlike rail, water and air transport, roads can be built to very remote locations(rural areas/villages) as well as to busy urban areas(cities). Roads can also be built on steep slopes as well as over rivers and valleys. Something which will be pretty difficult and expensive for railways to do.. As a result of this, road transport provides a lot of reliability and hence its the most accessible compared to other forms of transport.

                Secondly, road transport provides door to door services.Goods from a seller or supplier's warehouse can be transported and delivered right at the door steps of buyers. Services such as this cannot be provided by the other forms of transport(rail, air and water). Here also, children can be transported right from their homes in a school bus to school and from school to their homes.Another advantage or benefit associated with road transport is that it is economical for the transport of goods and people over short distances. Fares charged for transporting people and goods through road transport systems are less compared to the other forms of transport systems. Again delays in transit of goods on account of loading and handling are avoided. Goods can be loaded directly into a road vehicle and transported straight to their place of destination. Charges for loading and unloading are therefore reduced due to direct transportation. Furthermore, road transport systems requires less capital quality. Road transport requires less capital investment as compared to the other modes f transport. Wages paid to drivers and other workers as well as capital spent on construction and maintenance of roads and vehicles are much lesser compared to the construction and maintenance of tracks along railway lines. Also, road vehicles such as trucks and cars cost comparatively less compared to to trains, ships and aeroplanes.

Road transport systems also provide flexible services. Road transport has a great advantage over other modes of transport in the sense that it offers more flexibility. Here there are no fixed schedules. Its routes and timings can be adjusted and changed to individual requirements without much inconvenience. Road transport can therefore operate anytime. Also road vehicles can be diverted to different routes in case of blockages or accidents, Thus road transport provides minimal risk of damage and is most suited in transporting delicate goods like chinaware and glassware. Goods that are likely to be damaged in the process of loading and unloading. If goods are also to be transported immediately or quickly, road transport systems are more reliable than the rail and water transport because of its rapid speed. The ability to own vehicles by individuals is also another benefit of road transport. Here, people can now afford to have their own road or motor vehicles and initiate their own road services to market their products without causing any delay.

                Finally, with all these benefits of road transport, there are certain negative aspects associated with it such as traffic jams and street hawking. Thinking about traffic jams on the road can be quite scary and sickening. On the brighter however, traffic jams can be beautiful just as the saying goes, "beauty lies in the eyes of the beholder." By critical observation, anytime there are traffic jams on highways, the different colors of vehicles combine to create exciting color patterns, Some innovative artists take pictures of unusual beauty and beautiful paintings which they sell expensively to people. Hawkers are also happy anytime there are traffic jams on highways because that is when they make money selling to people in cars in traffic. Even though the hawking activity is very dangerous, it still puts money into their pockets. Hence from the above benefits, if a government invests more in  road transport systems, the quantity and quality of roads will increase as well as the potential for transport of goods. This will in turn result in the booming of the economy and thus higher income for the government.

CONSTRUCTION OF MODERN ROADS.

   Video on road construction at Taifa-St. John in Accra. Video credit: www.youtube.com.
             Roads are the lifeline of any economically vibrant nation. The road construction revolution has brought to light, the way to globalisation and a marvelous road transport development all over the world. As a result of this, not only is Ghana covering up with the rest of the world in the interconnection of countries but also the interconnection of cities with the best road transport system. Roads can therefore be defined as routes or paths that begin at one destination and lead to another.

             Road construction is perhaps one of man's earliest forms of construction. Some of the earliest roads were built by men such as John Metcalfe, a Scotsman who built roads within a distance of 180 miles(290km) in Yorkshire in England. Despite being blind, Metcalfe drained roads and built with three layers consisting of gravel, excavated road material and large stones. Modern tarred roads on the other hand were brought into existence by the works of two Scottish engineers Thomas Telford and John Loudon MacAdam. Telford and MacAdam devised methods of analysing the thickness of stones, road traffic, road alignment and gradient slopes. They also designed a method that involved laying broken large stones in symmetrical patterns and covering them with aggregate in order to create a solidified surface.  Their designs therefore became crucial to the evolution of road construction methods and as such became the standard for road construction projects. Hence a modern road can be defined as a route or way on land which has been paved or improved by the use of modern equipments to allow travel by some conveyance including a horse, cart or motor vehicle.   Roads that are also available for use by the public maybe referred to as highways or public roads. Furthermore, roads that lead into cities and towns can also be referred to as streets, avenues and more.

         Necessity they say is the mother of invention. In this perspective, the manual approach in the construction of modern roads does not seek to only make an impact on the overall quality of roads, but also to improve the condition of life in the society. For the best roads to be built, there are certain processes or steps that are involved which include planning, clearing, leveling, materials to use and maintenance. Before earth-moving machinery can be put to work for road construction, the land undergoes a series of surveys  to determine the route, distance, direction and elevation. This is known as planning. Other important factors to consider in the construction of a road is to know what materials would be used and which methods to employ.
Clearing is the first task after planning in the road construction process. This is done to rid the road of any obstructions that may inhibit construction such as stumps, bushes and rocks. In the early days, these obstructions were removed by hand or with the help of horse-drawn plows. Today, they can be removed by a machine known as the hydraulic excavator which digs the stumps or rocks out of the soil with its long extended arm and bucket.
Leveling the land is the next step after clearing the road. Before the advent of modern machinery, this task was undertaken with hand-held rakes and hoes. Today, this is completed by wheel loaders that remove larger chunks of dirt and rocks and leveled out by motor scrapers. Once the road is leveled, the motor grader is used to create a flatter and smoother surface before the application of asphalt or other materials.

            Although other materials such as gravel, sand and clay can be used for road construction, asphalt is one of the most common used in constructing modern roads and highways. Some experts recommend using a geotextile  membrane under a soil base to strengthen the surface. The base is then covered by about 9 inches(23cm) of soil,  followed by 6 inches(15cm) of coarse gravel or asphalt. A 4 inch(10cm) thick layer of crushed gravel known as "bank-run" gravel is deposited atop the base. Asphalt roads first appeared in 1824 on the Champs-Elysees in Paris. Asphalt soon became widely used throughout Europe and North America and is now used on 96% of all paved roads in America and also in the world. The first use of asphalt on modern roads however came from the work of Belgian immigrant Edward de Smedt at Columbia University in New York City.


Maintenance of gravel and asphalt roads can be as easy as scraping off the layer of material that covers the road. However, there are certain features of road-building that can aid in the maintenance and longevity of a road. For example, gravel and asphalt two-way roads are recommended to meet at a crown, a raised A-shape or midpoint section of a road. Single lane roads on the other hand do not require them. Also, the best time to pursue reshaping of roads is after rainfalls since the surface is looser and the amount of dust is reduced. This allows the ground to compact more effectively.

Today, there are 20 miles(32.3million km) of roadways in the world(as of 2002) with U.S holding the record for the highest number of roadways measuring 3.9 million miles as of 2005. Roads therefore continue and will continue to play a vital factor in modern civilisation with majority of roads being constructed according to city and national standards.

HISTORY OF ROAD TRANSPORT








                    Travel by road provides a lot of flexibility, convenience, speed and reliability whether at long or short distances in cities and towns. Hence it is the most preferred medium of transport in Ghana and other countries. Roads therefore connect cities to towns and villages. Road transport can then be described as the transport(movement of people and goods from one location to another) of passengers or goods on roads.





                   The history of road began with the development of tracks by humans and beasts of burden(horses, oxen, cattle, donkeys and camels). The first forms of road transport included humans carrying goods over created earth tracks or footpaths often following game trails such as the Natchez Trace during the stone age era. As commercial activities increased, the tracks were often flattened or widened to accommodate human and animal traffic. Some of these  dirt tracks were however developed into fairly extensive networks allowing communication, trade and governance over wide areas. The Ican empire in South America and the Iroguns Confederation in North America are examples of effective use of such paths. Overtime as animals were domesticated, horses, oxen and donkeys became an element in track creation and transportation of goods and humans.

          The travois, a frame used to drag loads which probably developed in Eurasia after the first use of  bullocks for pulling ploughs is believed to be the first vehicle. Pack animals, ridden horses and bullocks dragging travois required wider paths and higher clearances than people on foot and improved roads were required. As a result of this, by about 5000 BC, roads such as the ridge-ways were developed along ridges in England to avoid crossing rivers. In Germany, such ridge-ways remained in their predominant forms of long distance roads till the mid 18th century. Later, animal drawn wheeled vehicles were developed in ancient Sumer in Mesopotamia around 5000 BC. These animal drawn wheeled vehicles served as attachments to travois to reduce resistance on roads. This invention gradually spread to Europe and India in 4000 BC and China in about 1200 BC.

        With the advent of the Roman empire, there was a need for armies to be able to travel quickly from one area to another. To achieve this, the Romans built great roads using deep roadbeds of crushed stone as an underlying layer to ensure that they kept dry. Paved streets however came into existence in the Indus Civilisation around 4000 BC. With every increase in size and carrying power came the enhancements of roads, Developments like brick roads, the use of materials like sandstone blocks and basalt found their way into the road-laying industry as well. As far back as the 8th century, tar-paved roads such as roads in Iraq and Baghdad were found almost everywhere in the Arabian empire(Islamic Caliphate). During the industrial revolution, commercial activities increased and the need for improved roadways became very essential. John Loudon Mcdam(1756-1836) designed the first modern highways using inexpensive paving material of soil and stone aggregate. The 18th and 19th centuries also the massive use of roads , bridges and toll roads.However the turning points in the history of road transport came by with the invention of the bicycle, car, motorcycle and the bus. The earliest predecessor of the bicycle came in 1839, invented by Kirkpatrick Macmillan. In 1662, Blaise Pascal introduced the bus to the world though it was a horse-driven bus. The year 1862 also saw the invention of the motorcar with Etienne Lenoir's vehicle. In 1885 however, the motorcycle was invented by Gottlieb Daimler. In 2000 BC, the Minoans created a paved road of 50 kilometres that stretched between Knosses and Lebena, making it one of the noteworthy roads in the history of road transport.

 
         The period 500 BC also saw the establishment of the Royal Road under the command of Darius The Great. This road was a highway in its time and enabled the traversing of long distances in a very short time. It was such designs of roads that went into the inspiration behind the scientific approach of Pierre-Marie Jerome Tresaguet whose work in 1764 went into changing road transport even more. Hence modern roads for transportation involves a lot of  improvement in the society and also seeks to contributing for an easy life of transport.
