CHAPTER I

INTRODUCTION

Background of the Study:

Everyday, news about accidents is headlines in newspapers. An accident is a specific,

identifiable, unexpected, unusual and unintended external action which occurs in a particular

time and place, without apparent or deliberate cause but with marked effects. It implies a

generally negative probabilistic outcome which may have been avoided or prevented had

circumstances leading up to the accident been recognized, and acted upon, prior to its

occurrence. Accidents are inevitable but they can be minimized. Accidents are always present, it

may come in many ways may it be good or bad, but the most frequent accident that is often heard

are vehicular accidents. These vehicular accidents cause injuries and worst even death to those

who are involved. The frequent vehicles that encounter accidents are jeepneys, busses, private

vehicles but one of the major contributors to this accidents are motorcycles. A motorcycle is a

single-track, two-wheeled motor vehicle. Motorcycles vary considerably depending on the task

for which they are designed, such as long distance travel, navigating congested urban traffic,

cruising, sport and racing, or off-road conditions. Motorcycles are the most affordable form of

motorized transport in many parts of the world, and for most of the world's population, they are

also the most common type of motor vehicle.

Significance of Study:

If the factors that have caused these motorcycle accidents to increase have been

determined and the areas have been identified, this study will benefit the motorists especially the

motorcyclists and it may also benefit and help the traffic management agencies. This study will

be significant to those who own and drive motorcycles.

In the Philippines, people are shifting moods from automobiles to motorcycles, some of

the reasons are people are becoming aware of the advantages of having a motorcycle, it is cost
4

efficient in terms of fuel consumption and maintenance. It is also easy to handle and most of all

it is easy to maneuver. It can easily pass through busy streets with out experiencing heavy traffic

congestions.

Definition of Terms:

Accident – is a specific, identifiable, unexpected, unusual and unintended external action which

occurs in a particular time and place, without apparent or deliberate cause but with marked

effects. It implies a generally negative probabilistic outcome which may have been avoided or

prevented had circumstances leading up to the accident been recognized, and acted upon, prior to

its occurrence. It is constrained to an immediate incident, the occurrence of which results in an

unplanned outcome.

Accident rate – is the probability of the occurrence of an accident.

Motorcycle – is a single-track, two-wheeled motor vehicle. Motorcycles vary considerably

depending on the task for which they are designed, such as long distance travel, navigating

congested urban traffic, cruising, sport and racing, or off-road conditions.

Scope and Limitations:

This study is limited only to determining the accident rate of the motorcycles in Iloilo

City which comprises the following districts: Jaro, Lapaz, Molo, Arevalo, Mandurriao and Iloilo

City Proper from the year 2007 to 2008.

CHAPTER II

REVIEW OF RELATED LITERATURE

Motorcycles:

A motorcycle is a single-track, two-wheeled motor vehicle. Motorcycles vary

considerably depending on the task for which they are designed, such as long distance travel,

navigating congested urban traffic, cruising, sport and racing, or off-road conditions.

Motorcycles are the most affordable form of motorized transport in many parts of the

world, and for most of the world's population, they are also the most common type of motor

vehicle. There are around 200 million motorcycles in use worldwide, or about 33 motorcycles

per 1000 people. This compares to around 590 million cars, or about 91 per 1000 people. Most of

the motorcycles, 58%, are in the developing countries of Asia, while 33% of the cars are

concentrated in the US and Japan. In the two countries of India and China, there are a total of

only 6 million cars, but 71 million motorcycles. These numbers, worldwide, are dwarfed by the

number of bicycles in use, estimated to be near twice the number of cars, or close to five times

the number of motorcycles.

Technical Aspects:

Construction:

Motorcycle construction is the engineering, manufacturing, and assembly of components

and systems for a motorcycle which results in performance, cost and aesthetics desired by the

designer. With some exceptions, construction of modern mass-produced motorcycles has

standardized on a steel or aluminum frame, telescopic forks holding the front wheel, and disc
6

brakes. Some other body parts, designed for either aesthetic or performance reasons may be

added. A petrol powered engine typically consisting of between one and four cylinders coupled

to a manual five- or six-speed sequential transmission drives the swing arm-mounted rear wheel

by a chain, driveshaft or belt.

Fuel economy:

Motorcycle fuel economy varies greatly with engine displacement and riding style

ranging from a low of 29 mpg-US (8.1 L/100 km; 35 mpg-imp) reported by a Honda VTR1000F

rider, to 107 mpg-US (2.20 L/100 km; 129 mpg-imp) reported for the Verucci Nitro 50 cc Scooter.

A specially designed Matzu Matsuzawa Honda XL125 achieved 470 mpg-US (0.50 L/100 km;

560 mpg-imp) "on real highways - in real conditions. Due to lower engine displacements (100 cc–

200 cc) the motorcycles in developing countries offer good fuel economy. In the Indian market,

the second most selling company, Bajaj, offers two models with superior fuel economy: XCD

125 and Platina. Both are 125 cc motorbikes with a company-claimed fuel economy of 256 mpg-

US   (0.919 L/100 km; 307 mpg-imp) and 261 mpg-US (0.901 L/100 km; 313 mpg-imp), respectively.

Dynamics:

Different types of motorcycles have different dynamics and these play a role in how a

motorcycle performs in given conditions. For example, a longer wheelbase provides more

stability in a straight line. Motorcycle tires have a large influence over handling.

Motorcycles must be leaned in order to make turns. This lean is induced by the method

known as counter steering, in which the rider steers the handlebars in the direction opposite of

the desired turn. Because it is counter-intuitive this practice is often very confusing to novices—

and even too many experienced motorcyclists.
7

Short wheelbase motorcycles, such as sport bikes, can generate enough torque at the rear

wheel, and enough stopping force at the front wheel, to lift the opposite wheel off the pavement.

These actions, if performed on purpose, are known as wheelies and stop pies respectively. If

carried past the point of recovery the resulting upset is known as "looping" the vehicle

Social Aspect of Motorcycles:

Popularity:

In many cultures, motorcycles are the primary means of motorized transport. According

to the Taiwanese government, for example, "the number of automobiles per ten thousand

populations is around 2,500, and the number of motorcycles is about 5,000." In places such as

Vietnam, motorcycle use is extremely high due to a lack of public transport and low income

levels that put automobiles out of reach for many. In Vietnam, motorized traffic consists of

mostly motorbikes. The four largest motorcycle markets in the world are all in Asia: China,

India, Indonesia, and Vietnam. The motorcycle is also popular in Brazil's frontier towns. Amid

the global economic downturn of 2008, the motorcycle market grew by 6.5%.

Recent years have seen an increase in the popularity of motorcycles elsewhere. In the

USA, registrations increased by 51% between 2000 and 2005. This is mainly attributed to

increasing fuel prices and urban congestion, but is also partly due to television programmes such

as reality show American Chopper, or adventure-travel shows such as Long Way Down.

Mobility:

While people choose to ride motorcycles for various reasons, those reasons are

increasingly practical, with riders opting for a powered two-wheeler as a cost-efficient

alternative to infrequent and expensive public transport systems, or as a means of avoiding or
8

reducing the effects of urban congestion. In places where it is permitted, lane splitting, also

known as filtering, allows motorcycles to use the space between vehicles to move through

stationary or slow traffic.

. Types of Motorcycles:

There are three major types of motorcycle: street, off-road, and dual purpose. Within

these types, there are many different sub-types of motorcycles for many different purposes.

Street bikes include cruisers, sport bikes, scooters and mopeds, and many other types.

Off-road motorcycles include many types designed for dirt-oriented racing classes such as

motocross and are not street legal in most areas. Dual purpose machines like the dual-sport style

are made to go off-road but include features to make them legal and comfortable on the street as

well.

design creates a different riding posture.

Iloilo is a province of Philippines located in the Western Visayas region. Its capital is

Iloilo City and is located at the southeast portion of Panay Island, bordering Antique to the west

and Capiz to the north. Just off Iloilo's southeast coast is the island-province of Guimaras and

across Panay Gulf and Guimaras Strait is Negros Occidental .Iloilo City is politically subdivided

into 180 barangays. The barangays are grouped into six districts: Arevalo (13 barangays) ,City

Proper (45 barangays), Jaro (42 barangays), La Paz (37 barangays), Mandurriao (18 barangays),

Molo (25 barangays) .

All of the districts of Iloilo City were once individual towns. They were incorporated into

Iloilo when it became a city in 1937.

CHAPTER IV

DATA ANALYSIS

This chapter presents the findings of the investigation through the use of the descriptive

and inferential data analysis.

Total Number of Accidents:

Traffic accidents involving motorcycles increases every year, it is because people are

starting to appreciate the efficiency of motorcycles. They tend to occupy large distance with a

small amount of fuel and they can easily pass through congested highways and are easy to

handle. In Iloilo City the accident involving motorcycles increased greatly each year. The graph

shows the increase in motorcycle accident rate.

To summarize, the District of Jaro is the number one contributor of motorcycle accident

in Iloilo city. Jaro district is one of the busiest districts in Iloilo city. Almost all motor vehicles

like motorcycle, jepneeys and private vehicles from other town or municipality pass Jaro before

entering Iloilo City Proper. The district of Jaro serves as an intersection between two major roads

going to the municipalities of the province of Iloilo; this is road going to the Municipality of
21

Leganes and the road going to the Municipality of Pavia. This is one of the reasons why Jaro has

the most number of motorcycle accidents each year.

Arevalo is the lowest contributor of motorcycle accident in the year 2007 and 2008

because Arevalo District has the lowest number of barangay in Iloilo City comprising only of 13

barangays. Moreover, Arevalo is not densely populated and it is not a centre of business

transactions in Iloilo city.

Figure 13: The time where the most number of accidents occur.

Based on the graph above the time where most accidents occur is between 8-10 am, this

is because that during this hour, the streets are busy, and this is said to be a peak hour where all

tends to travel to school and to work. This is also the time where traffic congestions take place,

because of the motorcycles size they tend to pass through even small spaces and because of this

sometimes they are not being noticed that is why they end up having an accident.

CHAPTER V

CONCLUSION and RECOMMENDATION

Based on the study, the researchers found out that the t motorcycle accidents increased by

12% from 2007 to 2008 which indicates that the accident rate is high. This increase due to the

peoples’ mood is shifting to motorcycles over automobiles and its manoeuvrability when it

comes to passing through congested areas. Its only draw back that drivers are not knowledgeable

when it comes to proper road courtesies and traffic rules and regulations which results to more

accidents. Most accidents happened between 8 to 10 am, which is the peak hours for most

people. Furthermore during this time of the day most of the city loop roads are congested. It was

found out that most of the people committing these accidents ages 26 to 30. The male accident

rate was increase 22% while female accident rate was decrease by 79% from 2007 to 2008.

The researchers would like to recommend possible training and seminar regarding proper

highway courtesies. Education must also be given to road users. And for motorcycle drivers, they

should avoid driving when they are at the height of their emotion, or under the influence of

alcohol or drugs for it lead to further accident.
