Transcripts

hello class this is our first video

lecture in our subject

highway and railroad engineering so i

have already given to you your module

number one

study guide for module number one so uh

we will just

briefly discuss the uh the

content of the references as mentioned

in this

um module so

highway and railroad engineering for the

first part

we are to discuss the importance of

transportation

so here it creates stopping natural

resources

and markets and maintaining a

competitive edge over other regions and

nations

are linked closely to the quality of the

transportation system

how so well the speed costs

and capacity of available transportation

have a significant impact on the

economic vitality of an

area and the availability to make

maximum use

of its natural resources

so we are to maximize our natural

resources we will be needing

to improve our transportation system

why so well um does it mean that

having a good transportation system is

an assurance in economic success of a

country

well the answer is well if

only the transportation itself it is not

an assurance

rather it has a

impact it has a significant impact for

the

economic growth as mentioned here in the

second paragraph it reads

good transportation in itself so it says

here

so good transportation itself will not

assure

success in the marketplace as the

availability of transportation

is necessary but insufficient condition

for economic growth

is

success for that certain city

so meron roadway and what's next

economic growth nagai no it is

only one of the important ingredient for

the success of that

city so that is why

it says here in the second paragraph

transportation land

well in the absence of supportive

transportation services

it will serve to limit or hinder the

potential

for a nation or region to achieve its

economic potential

thus if a society expects to develop and

grow

it must have a strong internal

transportation system

consisting of good roads rail systems as

well as

excellent linkages to the rest of the

world by

sea and air thus transportation demand

is a by-product derived from the needs

and desires of people to travel or to

transfer their goods from one place to

another it is a necessary condition for

human interaction

and economic competitiveness

so that's how it is this to transport

people and goods in order to achieve

econ economic competitiveness

okay another thing to consider or to uh

to take note is that the availability of

transportation facilities

can inst can strongly influence the

growth

and development of a region or nation

good transportation permits the

specialization of industry or

commerce reduces costs for raw materials

or manufactured goods and increases

competition between regions

thus resulting in reduced prices and

greater

choices for the consumers

management good transportation system

there is a significant

growth in the supply of goods

now with the increase of the supply of

goods then

there will be a competition for the

prices

prices

[Music]

now if you have observed during this

quarantine season

as some

roads are being blocked for the lockdown

some commodities have increased their

prices

so that happened because of the

limitation of the transportation of

goods

so as you can see there is an effect of

the having a transportation system

with the economy okay

and also other things to

think about is that transportation is

also a necessary element

of government services so aside from the

transportation of roots

there's also the services such as

delivering mail defense and

assisting territories so this is also

a way to ensure the safety of

the um community not in mama mayan

in case of an invasion or

no no not in case of innovation but any

probable uh attack so at least

preparing they can transport their their

equipments to protect the

territories now we have been mentioning

transportation

and not detours it says here

it keeps on repeating good

transportation so

meaning we need to maintain the

health of the the um transportation

facilities or

for example if the road calls

it will take time before a certain

commodity

or services can reach a certain rejoin

so

the delay of time could mean

we can loss revenue or the worst case

will be loss of lives

for example

or let's say

poorly uh built in consideration so

in the meta transfer

hospital so that's the worst case

scenario there

the loss of lives because of poor

construction of roadway or any

means of transportation okay

so that is for the importance of

transportation

now we will be tackling also

for the 1.2 the different modes of

transportation here we are to read

pages 3 to 47

of garber and hoel i have given that

already that reference

in the ms teams you can view it or

download it so that you can access it

even though you're offline

okay so let's turn to pages 34 to 47

of garber and well well uh

or marami page's name

a short introduction and

we're not going to be in depth too much

with the with the topics now we will

just tackling some

uh ideas for you to familiarize

parameters maintain the anatomy

okay so we have their modes of

transportation this is um

page 34 of uh

traffic and highway engineering by

garber and

well for edition okay

so i have uh underlined the um

specifies emphasize not in my

ideas because if we tackle everything

then

it will take hours for us to discuss

this so

i just took some um some uh

thoughts from these references okay

so we have their modes of transportation

where we have different modes of

transportation

and each mode offers a unique set

of service characteristics in terms of

travel time frequency comfort

reliability convenience and

safety so

modes of transportation because of these

characteristics

now the term level of

service is used to describe the

relative values of these attributes

now the first one that we will be

uh discussing about a smooth of

transportation is the fright and

passenger

traffic now fright and passenger traffic

from the word fright we are talking

about the transportation of

goods so anonymous

mode of transportation

to transport goods now we have their

highways

railroads water and pipelines so

i you're familiar with the highway

transportation

so you can observe my trucks nothing

perishable goods we have also the goods

used for construction you are rsv

10 reinforcing steel bars and hollow

blocks

sand gravel then you have the

railroads railroad sima train

uh you have the lrt mrt

uh the pnr okay so we actually were

talking about

the transportation of goods so we can

use

railroads for that okay water

so uh water uh we have there the roro

so you can observe in the roro

they carry goods sometimes they carry um

cars vehicles and

transporting from one region to another

or one city to

another mapalgi tanzilang

katu began so to transport them we need

vehicle or mode of transportation like

the uh barge barco

banker and the fourth one is something

that

mostly are not familiar

a mode of transportation

is pipeline so to have an idea

we have there we have google search

pipeline transportation or pipeline

trans transport

their pipeline transport is the long

distance

transportation of a liquid or gas

through a system of pipes a pipeline

typically to a market area for

consumption

you were able to observe this they are

actually transporting

[Music]

that is contained in the vessel

well um many other way path to transport

these liquids or gases that is through

pipeline that's a pilipinas and a human

pipeline transport not in

so i use the manila times

paper here so

it says there running fuel products

through a pipeline is a simple matter of

practicality and

economics pipelines are still the most

cost effective way to move a large

volume of fuels

over long distances

the possibility of accidents

and then direction

now what are the pipeline transport here

in the philippines

okay here it says the philippines has

529.5 kilometers imagine that

uh of natural gas transmission pipelines

that

transport gas from where from

the malampara gas field to fuel three

power plants

the 500 megawatts san lorenzo the one

thousand megawatt santa rita and one

thousand two hundred megawatts illian

power plants in batangas province

and uh also there are nine other natural

gas pipeline projects

that is under construction for luzon

from 2017 to 2020

and according to the government's

philippine energy plan

or pep these are the batangas

manila one or batman one the batman

ii but the uncavity or the bat cave so

batman pipeline clark

pipeline subic fort bonifacio pipeline

sukad malaya sukhot kerino lines

and a city grass distribution network

the el satov

gas pipeline so these are the

pipelines existing here in

the philippines okay

so we go back to our

discussion

we go back to our discussion okay

so that's your pipelines under the

right in passenger traffic

the next one is the public

transportation

now public transportation is a generic

term

used to describe the family of transit

services

available to urban and rural residents

so this is not a single mode but a

variety of traditional

and innovative services which should

complement each other to provide

system-wide mobility

now transit modes this included

mass transit characterized by

fixed routes publish

schedules designated networks and

specified stops

so mass transit vehicles includes

buses light rail trolleys or rapid

transit that either shares space in

mixed traffic or

operate on grid separated rights of way

so what can you think about if you say

mass transit

well i'm thinking about yuma buses

nothing

like

[Music]

a

and also what else the air airway is not

then you have the

the uh philippine airlines

another must transit what else

we have there the lrt mrt

because they have schedules or

and designated networks

okay another one is the para transit

what is a para transit it is

characterized by

flexible and personalized service

intended to

replace conventional fixed route fixed

schedule

mass transit line so hindi shafix

routing dealership fixed schedule

para transit is available to the public

on demand by

subscription or on a shared right basis

and example of this include taxi car

rental dialer ride

and specialized services for elderly

medical and other designated users

when i read this definition one thing

came to my mind

we have the grub car

grab taxi grub tricycle

so young subscriptions

just to have a ride okay

now the last one is ride sharing

it is characterized by two or more

persons traveling together

by pre-arrangement such as carpool

vanpool or shared right taxi

car pooling sharing a ride with your

friends that is

ride sharing which actually

is advisable filipinas to

reduce traffic because if you have

observed there's

so many cars there's so many vehicles in

the road

and you can observe also that

on those vehicles is

well prior to the quarantine you can

observe it already

but during this quarantine season well

you can see of course my limited number

of of

uh passengers says

sharing you share rides with people

instead of each family buying a car

and then yeah

my

if only that family shares a ride

one car or two car for that family

then in the batman to reduce the volume

of

vehicle in the road you cannot just

solve traffic

by adding roads you can actually solve

the traffic

by discipline in itself

facilities like hospitals right

but if we have discipline if each

consumer is disciplined enough

if you you um

urge

not then so that's my um

my observation so whatever your

observation is well

and that's valid then

now for the another mode we have there

the highway transportation

now highway transportation is the

dominant mode

in passenger travel and one of the

principal

fried modes bucket to say

means of transportation highways

so here in the philippines

so let's uh see the statistics

uh let's first see what

are the major expressways or highways in

the

philippines so here we have an article

list major expressways and highways in

the philippines

we have here um i'm sure

one or one or more of this is

experiencing so we have there

south lausanne expressway we have there

the s-lex

the metro manila skyway the southern

tagalog

arterial road or star tollway

the uh subi clark tarlock expressway or

sc texts

expressway or mcx

the north luzon expressways or n-lex

the manila cavity expressway or cavitex

cabitex nahiya expressway on

big depot expressway

fungus in the onion expressway or tiplex

and the most famous the edsa

or the epiphany de los santos avenue so

these are our

major expressways and highways in the

philippines

statistics okay

uh before we go to the statistics we

have there

um regarding the new

expressways being built so this article

is um uh march 2022

so what is this new philippines

expressway being built

so the article says construction is

currently underway for the new

expressway connecting laguna batangas

and

quezon provinces in the philippines and

that is

the south luzon expressway toll road or

tr4 route which will measure

67 kilometer when complete

and should reduce journey journey times

for

drivers in the area the work on the toll

road project is

split into six stretches while the

intended completion date is

on 2022 so 2022

there is a proposal for a new tall road

linking the north luzon expressway

and the manila cavity expressway it is

being

evaluated the route will measure 15

kilometer

and feature both elevated sections

and tunnels building the new road link

with cut congestion and journey times

while boosting transport to

and from manila sport so yeah they are

construction

constructing new expressway now just as

i mentioned

um

about consumer then if we reduce our

vehicle they must i think the smaller

thing in pakistan

but then if the government

has been able to see that the

construction of these two expressways

will increase

economic growth then why not no

it's just my opinion if possible

foreign

now here are the reasons why for the

road building

process here are these uh

processes

foreign
