highway engineering tech report final
TRANSCRIPT
Last September 26, 2015, the Civil Engineering students of Central Philippine University
taking up Highway Engineering (CE4104) went on a road trip under the supervision of their
adviser, Engr. Gerardo Gepulango. The said trip covered the eastern part of Panay Island, which
includes several cities and municipalities in three provinces, namely, Iloilo, Capiz and Aklan.
The objectives of the trip are: to evaluate the present conditions of the highway system, to
observe the different modes of transportations in different places, and to suggest and bring up
recommendations for the observed problems and faulty conditions along the trip.
At 4:45AM PST, the group left Central Philippine University along with 1 minibus and 5
vans which carried at least 80 individuals. The convoy passed through the Iloilo Circumferential
Road (C-1 Road) towards the Municipality of Zarraga. The pavement was in good condition. It
was complete with guardrails, road signs and street lights. The pavement marking was also in
good condition. The only problem in that area was that the street lights weren’t used when it is
dark. Commuters have to rely only on their vehicle’s head light for vision. This can cause
accidents for there are certain parts of the roadway that are not visible when using only head
lights. It is recommended that street lights be utilized efficiently in these areas especially during
night time. Since the area is quite isolated from residential and commercial properties, proper
lighting is a big help in preventing not only accidents but also crime.
At around 5:00AM PST, the group started travelling along the highway of Zarraga,
Pototan, Dingle and Duenas. Parts of the range had guardrails while others do not. There are also
several road constructions, widening and repairing on-going in these areas. It is noticed that
although there are barriers and signs to inform commuters of men working ahead, standard
operating procedures for traffic work zones are not followed. For instance, the first warning sign
should have a decent distance from the work zone itself for worker and equipment protection in
case of an accident. Also, street lights and signs in some parts are covered with tree branches
making them less effective especially at night. Holes on the road were also found in some areas
of Pototan, and the pavement markings and signs were not maintained properly making it less
understandable for commuters especially those not familiar with the area. Some areas have 2
signs in the same place, one old, and the other new.
Arriving in Passi City at 5:45AM PST, it is noticed that most parts of the central business
district have on-going repair of the city roads. Thus, a detour was used but it did not have enough
information regarding the route to take towards other destinations. Also, an assistance desk
should be put up for first time commuters in the area. A short stopover was made in Passi City
Bus Terminal and it was noticed that it needed a facelift and renovation. Also, the terminal uses
angle parking scheme which reduces the time it takes to park a vehicle, creating less traffic. It is
recommended to put shoulders along the highway since many public utility vehicles utilize the
road. Shoulders can then be used as loading and unloading areas for buses or jeepneys, and also
as bays for emergency purposes.
At 6:25AM PST, the group stopped at Cuartero, Capiz for breakfast. The highway in this
place has very good sight distance, which is efficient and very useful. The road in that area was
very narrow and there were no pavement markings. This should be addressed to accommodate
bigger vehicles and to cater more volume as it is a national highway. Pavement markings should
also be placed to let the drivers know their position along a roadway. Also in some areas, the
obstructions such as houses were very close to the road itself. This is extremely dangerous both
for commuters and civilians. Some blind curves should have reflective signs to warn road users.
Some areas have signs when it is not really needed, while other critical areas which should have
signs do not.
At 7:00 AM PST, the road along Cuartero, Sigma, Dao and Mambusao in Capiz are
rough and mostly under construction. Holes were a constant sight along the way and it needed to
be fixed. Along the way, the road was a dirt road. Farther along the way, constructions are even
more. Again, proper traffic work zones system has not been applied. After the plaza in
Mambusao, the roads were rough and damaged with minimal holes in them. Considering the
number of vehicles passing through that area, it is very inconvenient and a hassle to pass by that
main road. In other areas, construction has not been finished and was left hanging. For instance,
a bridge was under construction and there were no traffic enforcers or any signs to channelize
and organize traffic flow. This caused a bit delay for commuters even in the early morning. In
some parts, obvious maintenance was needed for the road because cracks and unlevelled
pavement was evident. The bridges though, have proper markings and signs. Solid lines were
placed in the middle to indicate “No Overtaking” on bridges. Signs of the capacity of the bridge
were also found in almost every one. Some guardrails were dilapidated probably due to a
previous road accident. This should be repaired for it is important especially in reducing the
energy of a crash. There is one part of Brgy. Atiplo in Mambusao where the highway utilized
only one lane because the other was being replaced. It is noticed that traffic was building up at
the ends of the work area. It is also recommended to have shoulders along the roadway. The
drainage system in this area is also visibly broken. Fixing this is important.
After Capiz, the next province is Aklan. The first municipality is Altavas. The pavement
is smooth and concreted, although some areas utilize single lanes only due to construction. The
pavement markings and signs along blind curves are visible and are reflective. Majority of the
road along Altavas are zigzag roads, which means that it is very important to place markings and
signs in the right place to prevent accidents. Also, major concerns in the zigzag roads are the
guardrails. Most curves are blind and sharp ones, therefore, it is necessary to put guardrails to
prevent vehicles, especially but not limited to large ones, from overshooting the road and hitting
or falling from high cliffs.
The next municipalities were Batan and Balete. Some parts were also zigzag roads, and it
is noticeable that the consistency of the signs was decreasing especially in sharp and blind
curves. There were guardrails but very low ones. The pavements though, are in good condition
and are installed with curbs along edges. Noticeable in these towns are the work zones, because
they had early traffic warning devices and signs. Another fault is that, there were no street lights
in this area. At night commuters have to rely again on vehicle lights. This is prone to accidents
and crimes. There was mild traffic, as these are the towns approaching the bigger town of
Kalibo, the capital and main business center of Aklan.
As the group reached Kalibo at around 8:30AM PST, a noticeable change in the amount
of vehicles, mostly tricycles, motorcycles and private cars, was observed. Since Kalibo is a main
town for commerce in Aklan, it is obvious that pedestrian and vehicles share the streets.
Approaching the town proper, the highway was in good condition and it was wide at 4 lanes.
This can cater more vehicles at a given time. The main mode of transportation in Kalibo is the
tricycle. The land area of the town is small compared to other cities, so taxi cabs and jeepneys
are not used. Jeepneys are only for town-to-town use. The pavement in Kalibo is in good
condition and is well maintained. There are street lights and signs are everywhere. One problem
though is that the roads are very narrow, two lanes per direction at most in the town proper. It is
a good thing that signs were placed along arterial highways that prohibits parking at any time.
With this, traffic can be reduced by a little. Median strips were also It is observed that even at
9AM, the road was quite congested already. This is due to the high density of pedestrians in the
town proper. It is also noticed that there are a lot of construction on-going. This is a sign that the
town is becoming more competitive in the economic scene. It is noticed that in Kalibo, special
areas of interests such as malls and other large commercial establishments have heavy traffic in
its vicinity. This is due to the fluctuation of people and vehicle arriving in the area, adding the
fact that it was a weekend. Since motorcycles are the major mode of transport, the roadways are
not organized because motorcycles keep on cutting through traffic. Contrary to popular belief,
motorcycles cutting through lanes are the major contributors of traffic jams and on road
accidents.
At 10:25AM, the group left Kalibo and was on the way to the Roxas City. Along the trip,
one of the municipalities passed by was Ivisan. The highway in here is a two-lane two-way road.
The condition of the concrete was good with decent markings, although there are some point
where the obstructions are too close to the right-of-way, so vehicles have to move across the lane
to give space and avoid collision.
While traveling the road towards Roxas City, an unexpected mishap occurred as the
minibus carrying the female students overheated and was forced to stop in Sapian. The rest were
told to go to Robinson’s Place Roxas City and wait for further instructions as additional vans
were rented to cater the female students. The rest of the class arrived in Roxas City at around
11:50AM and it was noticeable that along the main arterial highway towards Robinsons, there
was a severe traffic jam towards the direction of the downtown area. This is caused by the large
amount of vehicles and given the fact that is was rush hour. The road in Roxas seems to be well
maintained and signs were a constant view along the road. The concrete pavement was in good
condition and seems to be new.
At 4:00PM, the class was on their way back to Iloilo City. The road along the way was in
good condition. There were shoulders in some areas. The only thing that bothered everyone as
they passed by through the mountainous areas was that there were no street lights. Also, several
blind and sharp curves were noticed to have no reflector signs to ward danger ahead. Vehicles
only relied on the natural light from them moon and also from their head lights. This is very
dangerous as these areas are very remote and it is the route taken by many busses heading
towards Northern Iloilo.
After the 16 hour road trip, observation, evaluation and assessment of the highways along
the numerous municipalities and cities in the provinces of Iloilo, Capiz and Aklan, numerous
problems and inefficient highway engineering have been noticed. The highway system in these
three provinces has yet to achieve so much to attain perfection in its slate. What lacks in the
whole length of highway is consistency. Some areas have proper pavement markings, while
others don’t. Some areas have properly installed roadside signs while others, especially when it
is needed the most do not. Some areas have street lights, mostly in commercial and town centers,
while other areas do not. Some roads have shoulders and others don’t. Same is true with
guardrails, some areas that do not need guardrails have them, while some that need it the most,
especially in steep roadside cliffs, do not have it. It is noticed that in areas with more population
and commercial establishments, the highway system and management, which includes
maintenance and rehabilitation, is better compared to areas with less population and are isolated
or far from civilization. This maybe the effect of poor governance and funding, as areas with
more voters tend to have more government projects compared to those areas near agricultural
lands and where people are very little. These problems should be addressed and put in high
priority as highways are vital not only in travel but also in trade. A good highway network
system reflects good governance and funding. The earlier these problems along roads are fixed,
the more accidents will be avoided, thus resulting to less damage in property and casualties
among civilians.
In this picture, the trees were inside the right-of-way and it defeats the purpose of the
guardrails installed.
This picture shows a dirt road which is very hard to
use, added the fact that it is wet and muddy. Concrete
pavements should be put in this area.
The picture shows a bridge where
the concrete pavement is rough and there
is no pavement marking dividing the
lanes.
The picture shows a road with a very high slope. Drivers cannot see on
the other end. Warning signs should be put in these areas.
This picture shows
a curve without signs to
warn commuters. It is very dangerous especially at night. Also this
area have little to no streetlights.
This picture shows a blind curve having
signs. But the pavement markings should include a
solid line because overtaking is not allowed in blind
curves.
This photo shows a road under repair.
Proper traffic work zone standards have not been
followed.
This photo shows a highway utilizing a
single lane only due to construction. The traffic sign
was not used well for it was facing the wrong
direction.
This was taken in Passi City. The major road
entering the city was under rehabilitation to be converted
to 4 lane highways. Not enough signs indicating alternative
routes were placed in the area.
Cuartero, Dao, Dumarao, Mambusao
The shoulder under construction in the left
part should have delineators separating
construction from the usable roadways.
This road is confusing because it is not sure whether it is a
three-lane with reversible lane, or a two-lane road because of lack
of pavement marking dividing the lanes.
This road is very narrow making it dangerous for busses
like the one in the picture. Especially in high speeds, this road is
prone to accidents.
This road in Capiz
is a dirt road. This is very bad for the tires of
vehicles and it is very inconvenient to use
in rainy days.
This is a bridge in Capiz where the concrete
pavement is very badly maintained. Also, the sign
indicating capacity is covered by obstructions.
The road shown here is not on a level ground. It is dangerous for high speed vehicles like
busses and trucks. Warning signs should be placed in here.
Improper channelization is applied while using equipment
for construction.
This is a very
sharp curve road.
And while guardrails are installed, warning
signs with reflectors should be put also. It is
especially useful at night.
The part of the road under
construction was not given enough work
space. Not enough warning signs can lead to
accidents especially at night.
Kalibo
4 lane highway approaching Kalibo, showing that vehicles use the outer lanes as parking
lots.
Road in Kalibo showing that majority of
road users are tricycles and motorcycles. It is
the main mode of transportation in th
Traffic jam in Kalibo. This is due to the
number of vehicle volume passing through
only a 2 lane city street. Road widening is
recommended.
Traffic enforcer needed to control traffic in an intersection in Kalibo. Traffic lights will
be very helpful in this area.
Intersection in Kalibo where the pavement
have no markings. Recommended to put markings
as guide for drivers. Also, put traffic lights to
minimize traffic jams
\
Ivisan, Sapian, Roxas City
.
Although the road is four lane, only 2
lanes are utilized because the outer lanes are too
close to the roadside establishments.
This is a school zone but no signs to
reduce speed was placed anywhere in the
vicinity.
