Ants and Traffic Jams: Can Ants Solve Traffic Congestion?

.
Note: In conducting literature search for my Katipunan traffic congestion study, I encountered an interesting video about the topic "ants and traffic jams." In this video, the ant colony optimization algorithm is discussed in connection with solving a perennial urban problem: traffic jams or congestion.

Katipunan Traffic: Aerial View of Katipunan Avenue (in the Vicinity of Ateneo de Manila University)

. Caption: An aerial view of Katipunan Avenue (in the vicinity of Ateneo de Manila University). Map extracted from wikimapia.org by Raffy Saldaña (http://raffysaldana.blogspot.com/)


NOTE:

To understand why traffic congestion occurs in Katipunan Avenue in the vicinity of Ateneo de Manila University, one has to consider the location and the movement of people and vehicles in the area.

As can be seen from the map shown above, a major part of Katipunan Avenue between the flyover and University of the Philippines-Diliman is covered by Ateneo de Manila University and Miriam College. Katipunan Avenue divides the combined area of Ateneo and Miriam and Xavierville Subdivision in Loyola Heights. In the morning, there is an influx of vehicles crossing Katipunan Avenue from Xavierville going to Ateneo and Miriam. Also, vehicles coming from La Vista Subdivision (near Miriam College) have to cross to the other side of Katipunan and make U-turns going to Ateneo or Miriam.

A similar event occurs near lunchtime (around 11:30 a.m.) when pre-school students from Ateneo and Miriam leave their respective schools, contributing to the traffic congestion during lunchtime (from 12:00 noon to 1:00 p.m.). In the afternoon, around 3:00 p.m. another traffic congestion occurs when grade school students from Ateneo and Miriam leave their schools. The next traffic congestion occurs between 4:30 p.m. until 6:00 p.m. when high school students, college students, and employees of Ateneo and Miriam leave the two campuses.

However, a major contributing factor to the traffic congestion in Katipunan Avenue (in the vicinity of Ateneo and Miriam) is the fact that Katipunan Avenue (which was made part of C-5 Road, a national highway) ends at the La Vista area in the intersections of C.P. Garcia (near University of the Philippines-Diliman) and Tandang Sora Avenue -- which are much narrower roads compared to Katipunan Avenue.

COMMENT:

TO THE METROPOLITAN DEVELOPMENT AUTHORITY (MMDA): NO MATTER WHAT TRAFFIC SCHEME YOU "EXPERIMENT" IN KATIPUNAN AVENUE, IF YOU HAVE NOT SOLVED THE STRUCTURAL LIMITATION OF KATIPUNAN AVENUE (THAT IS, IF KATIPUNAN AVENUE IS NOT YET EXTENDED TO COMMONWEALTH AVENUE), THERE WILL ALWAYS BE TRAFFIC CONGESTION IN KATIPUNAN AVENUE (IN THE VICINITY OF ATENEO AND MIRIAM).

WHY SHOULD THE LOYOLA HEIGHTS COMMUNITY BE "PUNISHED" BY YOUR TRAFFIC "EXPERIMENTS" WHEN YOU KNOW FOR A FACT THAT THE AREA OF KATIPUNAN AVENUE (IN THE VICINITY OF ATENEO AND MIRIAM) IS A SCHOOL/RESIDENTIAL AREA?

Katipunan Traffic: Congestion on August 20, 2008 (Due to Suspension of Classes)

.



NOTE: Last Wednesday, 20 August 2008, the Philippine National Disaster Coordinating Council (NDCC) decided to suspend classes in all levels mid-day (12 noon) due to heavy rain. I drove all the way from Alabang (and hurdled the traffic in South Superhighway and C-5 road) to be in time for my first class at 11:30 a.m. When I arrived in Ateneo, we were informed that classes were suspended starting at 12:30 p.m.


I was not feeling well that day, I had a bad case of sore throat and headache. I wanted to go home to rest but there was heavy traffic inside and outside the campus due to sudden influx and outflux of vehicles. I decided to leave my car inside the campus and walked to my condominium unit in Xavierville. Along the way I took photos and video clips of heavy traffic congestion in Katipunan as a result of the suspension of classes during mid-day. I estimated that the congestion lasted for more than two hours.


I came back to school at night to get my car when traffic congestion was already gone.

COMMENT:


To the National Disaster Coordinating Council (NDCC) -- please do not suspend classes during mid-day. If you have to suspend classes, do the announcement the night before so that students need not go to their respective schools anymore. Also, please leave the responsibility of suspending classes to school heads (principals and presidents). In the case of Ateneo and Miriam, I don't think that classes had to be suspended last Wednesday. What resulted was ANOTHER DISASTER because of heavy traffic congestion due to sudden influx and outflux of vehicles.


Things like heavy traffic congestion in Katipunan can be avoided if there is proper planning and coordination.

BSPT Batch D: Reunion with Tess and Friends

.
Note: Tess Gagui-Ichinose (my college classmate and friend, NSDB-PNC BSPT Batch D at the Phillippine Normal College) and her family who are based in Tokyo, Japan were in town recently. Last Tuesday, 19 August 2008, we visited Tess in her condominium unit in Alabang. Tess recently celebrated her birthday. Aside from Tess, those in the photo are Morey, Ronald, Cora, myself, and Chloe (Cora's daughter who is also my inaanak or godchild).

Below are some photos taken during Tess's post-birthday celebration in Alabang. Note: A Filipino birthday celebration is incomplete without the 'pancit' (Filipino-Chinese pasta). The 'pancit' is for 'long life'.

Katipunan Traffic Monitor: "Car Race" on a Monday Morning

.

Caption: Two cars appear to be engaged in car racing in the Katipunan-Aurora flyover on Monday, 18 August 2008, about 6:00 a.m.


Note: This morning (Monday, 18 August 2008) I took a video clip of traffic flow in the vicinity of Katipunan-Aurora flyover near Ateneo Grade school. Today is a NON-WORKING HOLIDAY so there are no classes (all levels) and offices. I was surprised to see two cars that appear to be engaged in car racing in the Katipunan-Aurora flyover at about 6:00 a.m. I estimate that the speed of each car is more than 100 km per hour. Click on the photo or the link to see the video.

Katipunan Traffic: The Tricycle Factor

Tricycle ban at Katipunan Ave draws complaints

By DJ Yap
Philippine Daily Inquirer
First Posted 18:46:00 08/17/2008

MANILA, Philippines--Tricycles have been banned from plying the stretch of Katipunan Avenue by the Metropolitan Manila Development Authority, drawing complaints from transport operators, students and residents.

In another attempt to ease traffic on the busy thoroughfare, the MMDA began strictly enforcing the tricycle ban on Katipunan Avenue last Friday, saying tricycles led to even worse traffic in the area.

But Alex Baay, president of the Loyola-Pansol Tricycle Operators and Drivers Association, said the ban drew complaints from passengers and residents especially those headed to the Ateneo de Manila University or Miriam College.

"A lot of passengers are affected, especially students. They have to walk several meters just to go to the other side," he said in a phone interview.

Baay said he, along with barangay (village) and transport leaders, sought a moratorium on the tricycle ban with Quezon City Vice Mayor Herbert Bautista, who was the acting mayor in the absence of Mayor Feliciano Belmonte Jr., in a recent meeting.

But nothing was set in the meeting, as the MMDA had yet to respond to their written request, he said.

Baay added the erratic traffic policies of the MMDA, such as rerouting schemes and the closing and opening of U-turn slots -- not tricycles -- have been causing the traffic gridlock in the area.

But MMDA Traffic Operations Center Executive Director Angelito Vergel de Dios disagreed, saying tricycles were a big factor in the traffic situation on Katipunan Avenue.


"They're not supposed to be there. They affect traffic. They obstruct passing vehicles all the time when turning corners," he told the Philippine Daily Inquirer, parent company of INQUIRER.net.

Vergel de Dios added that the MMDA was only enforcing an existing tricycle ban on national roads.

He also said the agency also reopened a U-turn slot in front of Miriam College to help ease traffic "in the middle of C.P. Garcia and Aurora Boulevard."

Vergel de Dios said that as of Sunday, the MMDA's proposal to change the entry point of Ateneo from its Gate 2 to Gate 3 still remained under discussion by the school board.

The MMDA proposed restricting entrance to the campus to its Gate 3 instead of Gate 2 in order to prevent bottle-neck traffic there.

Motorists, most of them parents of students, have assailed the MMDA for its rerouting schemes, which they claimed turned the area into a cause for road rage because of traffic gridlocks.

Katipunan Traffic Without Congestion

.
Katipunan traffic without congestion???

Yes, it is possible... but only on a Sunday :)

Below is a videoclip of Katipunan traffic (in the vicinity of Ateneo de Manila University) taken on Sunday, August 17, 2008, 6:10 p.m. as part of a preliminary study on traffic congestion in Katipunan.

Imagine There's No Traffic

.
Note: My blog is about my world (Raffy's World) which intersects with the world of thousands of people living/working in Loyola Heights, Katipunan area in Quezon City, Metro Manila, Philippines.

Part of this world is the traffic congestion occurring every weekday (which is true in most parts of Metro Manila).

Today, I remember the song of John Lennon -- IMAGINE.

What if we include a paragraph in the song about traffic?

Here is my first attempt:


Imagine there's no traffic
Congestion in Katipunan
No wasted time and gasoline
And no air pollution too
Imagine all the people
Living for today


Below is the lyrics of the song "Imagine" by John Lennon:

"
Imagine there's no Heaven
It's easy if you try
No hell below us
Above us only sky
Imagine all the people
Living for today

Imagine there's no countries
It isn't hard to do
Nothing to kill or die for
And no religion too
Imagine all the people
Living life in peace

You may say that I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will be as one

Imagine no possessions
I wonder if you can
No need for greed or hunger
A brotherhood of man
Imagine all the people
Sharing all the world

You may say that I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will live as one
"

Cheers,

Raffy :)
