The introduction of the motor vehicle as a means of road transport worldwide has facilitated the easy movement of man from one place to the other.

The movement of goods and services on spatial basis has also made easier and faster than ever and even much better in the subsequent generations to come.

However, motor vehicle transport has also come with a high price in terms of lost of life, properties and socio-economic activities

In the year 2001 alone, the country was rated the second highest road traffic accident prone among six (6) West African countries with 73 deaths per 10,000 accidents. From January to March 2003, Accra alone recorded about 1417 motor accidents involving 1225 vehicles (AFRICANEWS online – May 2003).

Page 4: By James Kweku Eshun & Christian Kwesi Owusu Department of  Geography & Regional  Planning

It has been estimated that over 300,000 persons die and 10,000,000 to 15,000,000 persons are injured every year in road accident throughout the world.

Detailed analyses of global accident shows that fatality rate per licensed vehicles in developing countries are very high compared to industrial countries

In Ghana, mechanical, human and environmental factors are being known as the causes of road accident in the country, most especially mechanical factor (Motor Transport and Traffic Union (MTTU) Annual Report 2004).

Page 5: By James Kweku Eshun & Christian Kwesi Owusu Department of  Geography & Regional  Planning

Records available indicates that in the year 2004 in the Cape Coast Metropolis, the number of accident cases reported were 1290 where death cases were 316 and injured cases were 1734 with 1667 vehicles involved in these accidents.

In 2005, 1025 cases of accidents were reported out of which 208 deaths occurred and 1436 injuries reported at which 1375 vehicles were involved in accidents in the metropolis.

Page 6: By James Kweku Eshun & Christian Kwesi Owusu Department of  Geography & Regional  Planning

Road traffic accident has serious consequences on the nation’s economy, the casualties, families, friends as well as the society at large. The nation spent about 2% of the country’s Gross National Product (GNP) on medicals, funeral bills of casualties and repairs of damaged vehicles. This 2% of GNP amounted to 2.64 trillion cedis (US 330 million) - (NRSC, 2006).

This potential labour loss is high in Ghana and the estimate of such losses by the technique of disability adjusted lost years (DALY) is about 9,000 for the city of Accra alone between 1991 and 1995 (Kissah – Korsah et al 2005).

Finally, road traffic accident is responsible for large number of morbidity and mortality rate in Ghana. About 8,000 people die in road traffic accident every year (Abane, 2004).The question is where are those places of which road traffic Accidents is rampant?

BLACK SPOTS

Black spots are those areas which have recorded a very high frequency rate of road traffic accidents within specific period of time. For this analysis black sport are places or location where road traffic accidents had occurred on more than three (3) consecutive times

The total number of cases is used to set a criterion for black spot locations in the Cape Coast metropolis. Eg. Pedu Junction (33/342*100% = 9.7 %)

Black spot area within the metropolis:

oPedu Junction (33)oUCC East Gate (30)oMoree Junction (22)oNkanfoa/Third Ridge (22) o Yamoransa (21)oKotokuraba (20)oSiwdu (18)oKingsway (15)oAbura (15)

CASUALTIES INVOLVED ROAD TRAFFIC ACCIDENTS IN THE CAPE COAST

Casualty according to Road Safety Commission (NRSC 2006) refers to a crash resulting in injury, death or property damage and which involves at least one vehicle on a public road.

Is also the resultant of any road traffic crash of which victims are either injured (serious and minor) or killed (fatal) within 30 days of the crash

Serious Injuries Involved in Road Traffic Accidents

Page 26: By James Kweku Eshun & Christian Kwesi Owusu Department of  Geography & Regional  Planning

Time refers to the period in which an event occur. Geographers have a strong ideology that everything exist and happens in space and time. Time under this study is grouped into morning, Afternoon and evening

Time that Road Traffic Accident happened in Cape Coast

Causes and Classification of Road Traffic Accidents

Page 29: By James Kweku Eshun & Christian Kwesi Owusu Department of  Geography & Regional  Planning

A total of 9 black spots locations were identified which were comparatively competitive to each order.

Most of the casualties recorded were minor injuries.

Fatality rate in 2011 was relatively high compared to previous years where most of this casualty occurs at vantage junctions and corners of the roads in the Cape Coast Metropolis.

Most of the vehicles involved in road traffic accidents were private vehicles

Most road traffic accident happened in the evening.

The most causes of RTA’s in the metropolis can be attributed to human factors.

54% increase in number of cases recorded between 2001 and 2011 (From 157 cases in 2001 to 342 cases in 2011).

Page 30: By James Kweku Eshun & Christian Kwesi Owusu Department of  Geography & Regional  Planning

In all the total number of cases recorded for each road traffic accident variable has increased within a 10 year gap, that is from 2001 to 2011 irrespective of educational campaign, hence new strategies should be adpted

Page 31: By James Kweku Eshun & Christian Kwesi Owusu Department of  Geography & Regional  Planning

Adequate and effective signs and road markings

Mandatory for every driver in Ghana to go for an eye test, at least once every one year

Make the use of speed cameras to capture, trap and punish drivers that speed on our trunk roads

Sustained traffic safety campaign

Coordinate, monitor and evaluate road safety activities, programmes and strategies

Proper check up of all vehicles at DVLA for road worthy certificate

Good roads and constant maintenance of roads
