offices Jan split also noticed that some

people preferred to ride bikes While

others took tricycles or jeepneys which

were popular modes of transportation gen

split decided to make a chart to keep

track of the different types of trips

and how many people were making them he

used colorful pictures to make his chart

fun and engaging and he was excited to

see the patterns that emerge

[Music]

oh

hi I'm Dr roll master of Transportation

Chief generation is the first step in

the first step Transportation

challenge split want to understand where

people were going and how far they

traveled he decided to create a map of

his City and mark the different

destinations people were traveling to he

saw different kinds of trips like going

to the market going to the university or

going to work Jan split used different

colors to represent the different

destinations on his map and Drew arrows

to show the flow of trips from one place

to another

to see

to see him go around his City and how

different

sessions were connected

[Music]

hi I'm Dr ha master of Transportation

drip distribution is a process by which

the trips generated from each zone are

allocated to other zones in the study

area this step estimates the

destinations of the trips and the routes

they are likely to take these trips may

be within the study area or between the

study area and the areas outside the

[Music]

as Jan split continued his Adventure he

wanted to learn more about how people

chose the mode of transportation for

their trips he interviewed his neighbors

and friends to find out why they chose

to walk bike or take public

transportation Jan's split created a

survey to collect data on the different

modes of transportation people used in

his City

he also used pictures and illustrations

to make his survey fun and easy to

understand he discovered that some

people preferred to walk or bike for

short trips While others used buses or

jeepneys for longer trip he even learned

that some people used a combination of

different modes of transportation

depending on the distance and

convenience

[Music]

finally Jan split wanted to understand

why Vehicles Go in different ways he

then also remembered how the students

Walked In One path if even though there

are other possible path he learned that

different Transportation modes are

assigned to different routes based on

factors such as travel time and distance

Jan split created a map of his City he

pretended to be a traffic engineer and

assigned different vehicles to different

roads based on the data he collected

about trip generation trip distribution

and mole split he saw how traffic flowed

on the roads and how some roads became

congested While others remained

free-flowing

[Music]

hey I'm back final step in the

transportation forecasting process is

traffic assignment in this step the

estimated tips from each zone are

assigned a specific Transportation

routes based on the mode choice and the

available Transportation infrastructure

this step also estimates the topic flow

and travel time on each route

foreign

s you have successfully completed the

four-step model of the travel demand

forecasting

upon learning all the four-step model

you are now a traffic master

[Music]

[Music]

traffic master

[Music]

you began to think about how the

four-step model applied not just to his

trip but to his life as a whole

the trip generation could be our career

choices

the trip distribution could be the

different paths he could take the modal

split could be the balance between work

and personal life and the traffic

assignment could be the obstacles and

challenges we Face along the way then he

realized that the four-step model wasn't

just a tool for urban planners but a way

of understanding and navigating the

complexities of life

suddenly thought about the complex

problems that he Encounters in his

everyday life as a commuter first the

poor road conditions which can make

roads difficult and dangerous to drive

on

second limited access to public

transportation and lastly traffic

congestion that can cause delays can

lead to wasted time and increased air

pollution

because of these problems he also

thought of some improvements that can be

applied to those problems which makes

him kinda excited he thought that the

government should allocate budgets to

roads that need immediate attention

rather than the roads that are still in

good condition they should also conduct

regular inspections and maintenance

which can prevent damage and improve

road conditions making them safer and

more reliable for drivers the local

government for instance could also

invest in public transportation

infrastructure to provide people with

more Transportation options they could

also encourage the use of sustainable

Transportation option such as cycling

and walking by building bike lanes and

sidewalks they could also Implement

smart traffic Management systems such as

traffic lights that adjust in real time

based on traffic flow to optimize

traffic flow and reduce congestion Road

users should also be disciplined they

should know the rules and regulations to

create a safe efficient and fair

transportation system that benefits

everyone it is the responsibility of all

Road users as he finished studying and

do his homework he felt A Renewed sense

of clarity and purpose

couldn't wait to see where his journey

would take him next
