On weather and traffic
With the onset of the wet season, heavy rains have reminded us how terrible commuting can be especially in Metro Manila where public transport services are much wanting in terms of quality. But whether you are driving or riding, using private or public transport, there is always something about the rains that make you feel uncomfortable. Metro Manila’s roads are becoming more and more notorious for flooding and I guess that goes the same with many other roads in other cities as well. Drainage is almost automatically blamed but closer inspection of the cause of flooding shows even the newest drainage systems being unable to accommodate rain waters in part due to their being clogged (by garbage, mud and/or other stuff) or having inferior design for intense rains. With extreme weather now becoming the norm, that is not a good thing especially with what is perceived as poor maintenance of our waterways and road drainage systems. Just look at how overpasses get flooded everytime the rain pours; causing traffic congestion that could have been averted if only we can weather-proof our roads to a certain extent.

Low visibility even during the middle of the day plus slippery pavement surfaces due to heavy rains can cause congestion and lead to unsafe conditions for traveling. The latter outcome is even worse during the night and, in higher elevations, when you have fog to add to the complexity of the environment you are traveling along. Aside from travel time, nothing more serious like life or limb can be lost by practicing safe driving whenever it is raining hard. That includes slowing down, turning on your lights (for visibility) and refraining from undertaking risky maneuvers. Pedestrians and cyclists, too, need to take more caution knowing the higher risks they face or are exposed to when traveling under inclement weather conditions.

On cable cars as a solution to Metro Manila transportation problems
I was asked about my take on the pronouncement about cable cars being a potential solution to Metro Manila’s traffic woes. I say pronouncement because careful qualification of the news articles on this clearly show that this is not yet a proposal. I leave it to the reader to Google these articles on cable cars for Metro Manila.
The first thing that came to my mind are capacity and demand. What would be the capacity for such a system and what could be the demand given that you would have to determine where stations would be. There’s also the fear factor as many people would not be comfortable riding a vehicle so high up in the air and then of course, there’s the wind that will obviously have to be factored in the operation of such cable cars. Suitability is very much an issue here. Perhaps cable cars like the one featured in the news articles are more appropriate for cities like Baguio, Antipolo and Tagaytay? There are very limited applications for Metro Manila even including perhaps possibilities for Ortigas and perhaps Loyola Heights.
I like what my friend, Rene Santiago, said about the cable being one possible answer but not The Answer to Metro Manila’s traffic problems. I am aware of and quite amused by the comments posted on social media about the so-called ‘cable car solution’ as it is definitely not going to make a big impact on Metro Manila transport. I like comments proposing instead improved river transport as well as protected bicycle lanes around the metropolis. These are well-grounded proposals that have been proven elsewhere to be very effective in reducing congestion while mass transit projects are under construction and to be operational in 2 to 3 years time. I think it would be wiser to put your money on bike lanes and even bike bridges than in cable cars.
I was also asked about what should be the first project the new Department of Transportation Secretary Art Tugade should take on. Metro Manila is still very much a “battleground” for transport and traffic, and there are already projects lined up for implementation like the much delayed MRT 7 and the extension of LRT1. The new administration should strongly support such efforts, whether its via Public Private Partnership (PPP) or public funded. That said, I think the incoming Department of Transportation Secretary should work on an urban mass transport project in one of our major cities. Either Cebu or Davao come to mind as these cities are already also congested and would need to have an urban transit system (rail?) very soon in order to avoid becoming another Metro Manila. There are low-hanging fruits in these cities, for example, with the Cebu BRT ready to be taken on by the new administration for full implementation and Davao already being the subject of public transport studies pointing to it being ripe for a rail transit system.
Finally, there are also the outcomes of research & development work by the Department of Science and Technology (DOST). I am referring to the DOST-MIRDC’s road train, AGT and hybrid train projects. The road trains, for example, may be used for Bus Rapid Transit (BRT) lines that are proposed for C5 and Quezon Avenue. I also think it is worth considering for EDSA. BRT is not technology-specific as far as buses go so why not use Philippine-made buses for this? While these are still subject to third party safety and technical certifications, the Transportation Department could lend a helpful hand towards this certification and this could perhaps ultimately lead to building an industry out of these buses and trains.

Addressing congestion due to school traffic congestion
There are two important traffic news stories yesterday:
- MMDA successfully clears parked vehicles outside La Salle Greenhills
- MMDA sets drop off, pick-up points for Ateneo students
For some reason that’s a bit surprising for many, the MMDA seems to have solved two of the most enduring issues on traffic congestion along two major thoroughfares. LSGH is along Ortigas Avenue while Ateneo is along Katipunan Avenue (C-5). Both have high trip generation rates and a significant percentage of their trip gen is comprised of private vehicles. While, Ateneo’s trip generation has led to traffic congestion due to the sheer number of trips the university attracts, the congestion due to La Salle is due to the poor traffic management and lack of parking spaces for vehicles attracted by the school.
I only wonder why it took so much time to address these problems considering the solutions mentioned in the articles are basically ones that could have been implemented years ago. In the case of La Salle, good old fashioned traffic enforcement apparently did the trick. But then, the MMDA even with the LGU constraint could have been stricter before whether when they were under Bayani Fernando (BF) or any of his successors as MMDA Chair. With Ateneo, the scheme is very similar if not the same as what BF proposed over a decade ago when he was MMDA Chair. At that time though a touchy issue was the U-turn scheme he installed along Katipunan that cost trees and the former service road on the west side of the avenue. We can only hope that these claimed ‘successes’ will be sustained and ensure smoother flow of traffic along the major roads they directly affect.

Will a flyover at Katipunan-C.P. Garcia solve the traffic problem in the area?
I read a news article about the proposal by the Department of Public Works and Highways (DPWH) to construct a left-turn flyover at the intersection of Katipunan Avenue (C5) and C.P. Garcia Avenue in Quezon City. The flyover is supposed to be for vehicles turning left from the northbound side of Katipunan to C.P. Garcia Ave., which goes through the University of the Philippines Diliman
Will the flyover solve the traffic congestion problem in the area, particularly at the intersection and Katipunan in general? I would say no, it would not solve the congestion problem both for the intersection and for Katipunan. This assessment is due to the following reasons:
- The overpass does not address the root cause of congestion in the area, which is trip generation related. There are many major trip generators along Katipunan alone including three major schools (UP, Ateneo and Miriam) and a mall (UP Town Center). Add to this the traffic generated by the high density residential developments along Katipunan (notice the high rise condominiums lining up across Ateneo and Miriam?) and the through traffic coming from various areas that use C5’s Katipunan section.
- Congestion is caused by saturated intersections corresponding to Ateneo Gate 3 and main gate of Miriam College. Traffic going in and out of these schools are favored over through traffic along C5 resulting in congestion in the area. Perhaps it would be more appropriate to build overpasses to bypass these intersections.
- Congestion is caused by vehicles bound for and coming from the UP Town Center. The congestion due to traffic generated by the commercial development is actually alarming considering it is not yet completed and trips attracted and produced is not yet at full potential.
- The heaviest flows at the Katipunan-C.P. Garcia intersection are along Katipunan (northbound and southbound through traffic). Logic and traffic engineering principles point to grade separation to be more appropriate for such traffic and NOT for the left turn movement. A flyover should also be able to bypass UP Town Center as vehicles bound for the mall already blocks traffic along both sides of Katipunan and directly affects the intersection.
I think the DPWH should do well to re-assess their proposal along the lines of the reasons I have listed here rather than continue with the folly of building a left turn overpass alone. UP Diliman should also resist this overpass as, based on the news article, it would mean UP giving up some 8,000 square meters of its property for the project. UP already has given a lot for widening C.P. Garcia but that goes without saying that a through flyover might also require UP to give up property and particularly from its National Science Complex for such a project.

Shopping malls and Ortigas Avenue Extension traffic congestion
Recently, I noticed that traffic has somewhat eased along the eastbound side of Ortigas Avenue Extension. For one, this was probably due to the completion of road works and the reopening of lanes between Cainta Junction and Brookside. This improved traffic flow as traffic personnel didn’t have to resort to the balancing act that is the counter-flow scheme they had been employing to alleviate congestion for mostly home-bound traffic. But a major contributor to congestion was the Ever Gotesco Mall in the former Riverside industrial complex. Malls like this are major trip generators and if traffic coming in and out of the malls are not managed properly or facilities are not provided for efficient movement of people and vehicles, then there will surely be congestion along access roads. I stated that the Ever mall ‘was’ a major contributor because the mall recently closed down and the property is now fenced off from the road. At present, there is practically zero traffic that can be attributed to the former mall.
Following are a few photos of the closed and fenced off property that was the Ever Ortigas mall.
Jeepneys and UV Express vehicles now use the service road of the mall as a terminal.
It’s now a breeze passing through the eastbound section of Ortigas Extension in front of the former mall. There are signs stating the property has been acquired by retail giant SM. It will probably be transformed into an SM mall.
This driveway used to cause congestion as jeepneys and private vehicles exited the mall through this driveway and many turned left towards Ortigas westbound. These vehicle often effectively blocked traffic along the eastbound direction with queues reaching all the way past Countryside and reaching De Castro on a bad day.
There were only two shopping malls along Ortigas Avenue Extension – the Robinson’s Place near Cainta Junction and Ever Gotesco. Ever has recently close but it is expected to re-open as an SM Mall sometime in the near future. SM doesn’t have a mall in the area and the ‘nearest’ ones would be Megamall, Marikina and Taytay (not counting the Super Center beside Tiendesitas and the Super Center along Felix Avenue). If indeed an SM mall will be there soon, we could expect heavier traffic in the area given the trip generation characteristics of SM. Perhaps, though, there is an opportunity to improve traffic in the area if SM can consider some improvements to its driveways and circulation. They could probably do something like what SM Novaliches had done with their generous setback to ensure that there will be no serious congestion along Quirino Avenue due to mall-generated traffic.
SM will not be the only major commercial development that is expected to generate traffic that will lead to congestion along Ortigas Extension. Almost across the former Ever mall is a commercial development under construction with a building I think is too close to the road. Then there is also the commercial/residential project that is being constructed along the westbound side of Ortigas Extension near the Kaytikling Junction in Taytay, Rizal. I wonder if these had the necessary traffic studies to support their impacts on at least the immediate areas they will be affecting.

Unprepared and incomplete – realizations from the APEC transport experience
Before I forget about what transpired during the holding of APEC in Manila a week ago, here’s a couple of photos I found over the internet and shared via social media.
Commuters along Roxas Boulevard walk past a column of the unfinished NAIA Expressway, one of the transport infrastructure projects that has not been finished. [Photo from The Manila Bulletin]
APEC lanes and severe traffic congestion along EDSA – there’s an opportunity here for a prrof of concept test for BRT. [Photo from Facebook]
I saw many memes and read some articles mentioning BRT specifically as one solution to Metro Manila’s transport problems. The second photo above was modified to replace the car travelling along the APEC lanes with a bus.
It is easy to imagine what could have been if the government decided to use the event and the lanes they allocated for APEC vehicles to do a ‘proof of concept’ run of BRT services or at least express bus services (what some DOTC people call high quality bus services). Perhaps what could have been done for part of the 10 billion PHP expended for APEC was to buy a fleet of brand new buses and provided these for free public transport for people who would need to commute during APEC. Services along two corridors would have sufficed – these two would have been EDSA and Roxas Boulevard. [The other option would have been to talk to bus operators and cooperate with them to organize express bus services along EDSA and Roxas Blvd.] Aggressively promoting these free services ahead of APEC would also have meant commuters, including those who usually used their own vehicles, could have opted for these transport services and not affected by the ‘carmageddon’ that ensued over that period. There should have been services to the airport terminals, too, but I will write about this in another article.
The dry run could have yielded essential data for assessing the feasibility of such bus services as an alternate to rail systems that would take much time to build. Incidentally, if the LRT Line 1 Extension to Cavite was built right after the current administration took over, that line could have already served tens of thousands of passengers from the south who regularly commuted to Metro Manila for work and school. The first photo above does not lie about just how many people could have benefited from that rail project. Meanwhile, MRT Line 3 remains dysfunctional and with its reduced capacity could not handle the demand for transport that it should have been able to carry if services had not deteriorated over the years.

Improvements to alternative route between Rizal and Makati
I finally got another look at the conditions along the alternate road to Highway 2000 and C-6 Extension a couple of weeks ago while en route to Bonifacio Global City. Traffic along Ortigas Ave. is usually terrible these days even during the weekends due to the road and drainage works between Cainta Junction and Brookside. I am glad to say that there have been significant improvements to the section of Don Hilario Cruz Ave nearest to the Manggahan Floodway and beside the Megawide plant. There have been significant developments, too, along C-6 Extension in the Lupang Arenda area of Taytay, Rizal. Here are some photos of the area.
Don Hilario Cruz Ave., the road beside the Megawide plant and parallel to Highway 2000, is being improved with half the carriageway already prepared for paving. The other half appears to be graded is being used by vehicles.
A roller runs along the base layer of the road that’s being paved. These sections were usually muddy and full of craters during the wet season and very dusty and still full of potholes during the dry season.
Sections of C-6 Extension at the Lupang Arenda area have been widened and the expropriated lands are now being transformed into paved roads. The original sections have been overlayed with asphalt to improve their ride-ability.
Another section in Lupang Arenda shows finished PCCP for the eastbound side of C-6.
Another photo of C-6 extension. Once the finished lanes are usable, authorities will probably divert traffic there so they could also pave the rest of the road.
Travelers between Rizal and Makati/Taguig will benefit the most from the improvements along these roads. These will increase road capacity as well as travel speeds along this route. Now, if only authorities can also improve C-6 itself in Taguig…

On the severity of traffic congestion along Ortigas Avenue and the necessity of a mass transit line
With the worsening congestion along Marcos Highway due to the construction of the LRT Line 2 Extension to Masinag, I have been using Ortigas Avenue as an alternate route to go home. Granted, the stretch from the Park Place gate near Cainta Junction and Brookside is currently undergoing roadworks elevating that entire section (which is prone to flooding), and this is the main cause of much congestion as fewer lanes are usable to traffic. However, what is perceived to be relief from traffic once the project is completed will eventually and surely revert to a very congested Ortigas Avenue.
Traffic congestion along Ortigas Extension is primarily due to a dependence on road transport, particularly private vehicles, by people living along Ortigas Ave. and the roads feeding into it. The Manila East Road, for example, passes through the most populous towns of Rizal outside of Antipolo City. The dependence on road transport (especially private vehicles) is due to limited options for public transport. There are buses, jeepneys and UV Express but these, too, contribute to congestion due to their increased numbers and limited capacities given the high demand for public transport. Among the infrastructure proposed along this corridor is an overpass along Ortigas Ave. at Cainta Junction. A mass transit system has also been required along this corridor for a very long time but for some reason, such infrastructure has not been provided.
Severe traffic congestion along both directions of Ortigas Avenue Extension
Congestion stretches all the way along the Manila East Road
Night-time traffic congestion at the Tikling Junction
There is a proposal for a mass transit system along this corridor. Following are references to the project:
From the PPP Centre: https://ppp.gov.ph/?ppp_projects=ortigas-taytay-lrt-line-4-project
From CNN Philippines: http://cnnphilippines.com/metro/2015/07/22/neda-approves-naia-lrt-ppp-projects.html
I found it quite odd that the stations are not referenced according to the more common place names for the locations. For example, ‘Bonifacio Avenue’ should be ‘Cainta Junction’ and ‘Leonard Wood’ should be ‘Kaytikling Junction’. Nevertheless, this is the least of our concerns pertaining to transport and traffic along this corridor.
Perhaps the conditions are ripe now to finally implement transport infrastructure projects along this corridor. The proposal and approval of a rail transit line by NEDA means the corridor has the national government’s attention. The local government leaders along this corridor are also more progressive and aggressive than their predecessors. These include a very dynamic mayor in Cainta and the former governor-turned mayor in Antipolo. A collaboration towards better transport among these two LGUs alone would be influential and instrumental to improving travel along Ortigas Avenue.

Undas traffic
Metro Manila traffic is usually lighter during Undas – the days when we remember those who passed away. Many people go back to their hometowns and this is significant because many residing or working or studying in Metro Manila hail from other provinces. Of course, some people would rather go on a vacation during this time with many now opting to travel abroad rather than braving crowded cemeteries of their hometowns. Some do the so-called ‘staycations’ – basically staying put at home during the undas break (Sorry, staying in a hotel is technically not a ‘staycation’ as many people claim it to be.)
What are the facilities that are expected to be congested? These would be the gateways from Metro Manila to other provinces. These would be airports, sea ports, bus terminals and major roads connecting Metro Manila to the provinces. There would be similar situations in other gateways as well such as in Cebu in the Visayas and Davao in Mindanao. Of course, all roads leading to cemeteries, memorial parks and columbariums. These roads would be filled with people (mostly walking) and vehicles (mostly private cars and tricycles and pedicabs if local roads) who congregate in these areas to remember and pay tribute to their dead.
The congestion experienced in most roads during this time of year is usually manageable and local governments can and are usually prepared to address transport and traffic issues within their jurisdictions. Tollways also employ their own strategies and tactics to deal with toll plaza congestion. The Land Transport Franchising and Regulatory Board (LTFRB) issues additional temporary permits to bus companies to field more vehicles along high demand routes. Meanwhile, airports and seaports would have to deal with their own versions of congestion though it is expected that such peaking or spiking up of travel activity can be handled by many airports and ports considering that these facilities are supposed to be designed for higher than usual demands.
Here’s wishing everyone safe travels during this Undas weekend. Mag-iingat lalo na sa pagmamaneho. Huwag magpatakbo na tila hinahabol ninyo ang araw ng mga patay!”
Causes of congestion – road crashes and shockwaves
I noticed that a previous post on common causes of congestion is popular among those who read this blog. The causes mentioned there focused on the lack of discipline among pedestrians and motorists. Their behaviour (e.g., commuters standing in the middle of the road to get a jeepney or UV Express ride, jeepneys and UV Express stopping in the middle o the road to load/unload passengers, etc.) often lead to congestion as they effectively reduce road capacities.
Another major cause of congestion are road crashes. They don’t have to be fatal crashes as the road capacity reduction caused by stopped vehicles is enough to cause congestion along the road including traffic along the opposite direction. The latter phenomenon, if we can categorise it as such, is due to the inquisitive nature (i.e., uses) of people. Traffic approaching the crash site typically slows down as drivers check what happened. Following are some photos I took as we approached a crash site atop the Marcelo Fernan Bridge connecting the Islands of Cebu and Mactan. Note the build-up of vehicles behind the crash involving 3 vehicles.
Road crash involving 3 vehicles in the middle of the Marcelo Fernan Bridge in Cebu
The resulting congestion behind the crash site
Another view of the vehicle buildup upstream of the crash
Such events are typical causes of congestion and can actually be analysed using traffic flow theory involving waves in traffic. A generally normal flow of traffic (before the incident) is disturbed by the crash, which is assumed to be an isolated event. This results in a change in the traffic characteristics (flow, speed and concentration of vehicles) triggering a shockwave. The shockwave moves backwards and manifests through the chain reaction of drivers hitting their brakes in succession to slow down due to the incident. As such, it is possible to determine how long the build-up of vehicles would be upstream of the incident location.
