Quezon Ave. underpass at Araneta Ave.: some expectations and issues
The underpass along Quezon Ave. at its junction with Araneta Ave. is set to open to general traffic this coming week. I got this from a reliable source who was involved in the project as well as friends from the DPWH and the MMDA. If the opening pushes through, the underpass is expected, based on analysis, to ease traffic along both major roads with Quezon Avenue’s through traffic having the most benefit from the uninterrupted flow provided by the underpass. At-grade traffic management at the intersection will still be provided mainly by traffic signals but the substantial reduction of traffic attributed to the through movements along Quezon Ave. The reduction of congestion comes as a relief to a lot of travelers as well as businesses affected by the construction of the underpass in the last year. Fortunately, there has been little delay in the construction and so it seems that lost times due to construction-related congestion (translated here as sacrifices for those who had to endure daily traffic congestion and had to adapt to the situation) will finally be compensated for. Many, indeed, have been anticipating the eventual opening of the underpass, expecting the facility to solve congestion in the area.
The area has been subject to flooding considering its proximity to the San Juan River. Official data for flood occurrences in the area can be accessed through the Department of Science and Technnology’s (DOST’s) Nationwide Operational Assessment of Hazards website where it is clear that flooding will be an enduring problem for the underpass and surrounding areas. Recent reports (from last week until today) indicate that there is still the specter of flooding that will have to be addressed given that prior to the construction of the overpass, this issue had already been flagged by various stakeholders including the Quezon City Government. It is for this reason that the underpass will have pumps to ensure that water will not accumulate and lead to the closure of the facility in times of heavy rains resulting in flash or regular flooding.

Predictability of school-generated traffic congestion
I have written about schools generating much traffic. The same characteristics of trip generation make congestion along streets affected by the schools quite predictable. For example, traffic congestion due primarily to the trip generation characteristics of schools along Katipunan Ave. may be observed during 6:30 – 7:30 AM as well as around 3:30 – 4:30 PM. The afternoon congestion though is exacerbated by the presence of significant truck traffic using C5 as part of their routes. Other cases would have similar predictability and I pointed this out to some guests while we were having a coffee break from our day-long meetings. The following photos were taken in the mid-afternoon and shows congestion along Ortigas Avenue in Mandaluyong City, including along an overpass affected by school traffic generation from a private school (the school is the one with the dome in the photo). Traffic is typically bad between 3:20 to 4:30 PM, after which it subsides until after 5:30 when the afternoon to evening rush from workplaces to homes take over much of the road space.
View of the EDSA-Ortigas intersection showing the start of the build-up of traffic along the left turn overpass to Greenhills on the left side of the photo.
View of the same flyover at around 3:36 PM. Note the long queue along both lanes of the overpass.
View of traffic congestion from the 16F of the building hosting the headquarters of the Department of Transportation and Communications. The overpass featured in the preceding photos is shown with vehicles descending to merge with Ortigas Avenue traffic. Both directions of Ortigas Ave. are congested.
Congestion as seen from the street level. Vehicles descending the overpass are generally bound for San Juan while those on the foreground are bound for the EDSA-Ortigas intersection. Long queues are likely caused by a combination of high traffic volumes and non-optimal green time management at the intersection.
Another view of the congestion at both ground and overpass levels. Traffic is really bad when you have ambulant vendors walking along the overpass to sell their wares (e.g., cigarettes, candies, water, etc.) like what the man on the overpass near the van is doing.
Given the predictability of traffic congestion along this road, many motorists who have a choice or alternate route they can take avoid this road during such periods. Unfortunately, those taking public transport cannot avoid the congestion with passengers thereby incurring delays equivalent to wasted time. Most trips generated by such schools take private vehicles often having low occupancies (e.g., a driver plus a student = 2 passengers per vehicle). Perhaps schools should offer better school services/buses for their students? Or maybe there is a public transport option to be explored here? One thing is for sure and that is people at a young age learn that having cars is better than commuting. Such thinking is eventually carried over to when the same children become adults and an orientation favoring cars over public transport or even walking or cycling that they will eventually pass on to their own children, and so on. Perhaps our schools are in a very good position to influence the developing minds of their students and be responsible in promoting sustainable transport to their students.

EDSA traffic: view from the top
Traffic along Epifanio Delos Santos Avenue (EDSA) or Circumferential Road 4 is quite infamous considering it being a if not the main artery of Metro Manila and carrying much vehicular and passenger traffic between cities like Pasay City, Makati City, Mandaluyong City, Pasig City, Quezon City and Caloocan City where it has major junctions with other major thoroughfares like Roxas Boulevard, South Superhighway, Ayala Ave., Gil Puyat (Buendia) Ave., Shaw Blvd., Ortigas Ave., Aurora Blvd., East and Timog Avenues, Quezon Ave., North Ave., Roosevelt Ave., NLEX and A. Bonifacio Ave., Rizal Ave. and MacArthur Highway.
Shown in the following photos are traffic conditions along EDSA during a holiday, and typical afternoon peak and evening on a weekday. The section featured is the stretch from the Ortigas junction to Camp Aguinaldo. Visible in the photos are the high-rise condominiums along Connecticut Street (upper left) and the developments at the Araneta Center including the Araneta Coliseum in the Cubao commercial district. The green area on the upper right is Camp Aguinaldo, headquarters of the Armed Forces of the Philippines (AFP), while the rooftops at the right are of houses located in an high-end exclusive subdivision (Corinthian Gardens). In the middle of EDSA is the MRT-3’s elevated tracks.
Photo taken from the 35F of the Robinsons-Equitable Tower shows light traffic along EDSA during a holiday. Traffic probably is similar during Sundays while such volumes may be observed on Saturdays only in the early mornings; before 9:00 or 10:00 AM when the shopping malls open.
Photo taken at 5:44 pm showing traffic congestion on both directions (northbound and southbound) of EDSA including the overpasses at its intersection with Ortigas Ave. An MRT-3 train is visible in the middle of the photo.
Photo taken at 6:16 pm with the headlights and taillights indicative of the traffic density during the early evening. Such congestion now usually extends past 8:00 pm with cases where EDSA is still congested near midnight. Such cases are more common now rather than exceptional.

School traffic impacts – issues along Ortigas Ave., Part 2
I had written recently about traffic congestion along Ortigas Avenue that is due mainly to traffic generated by a private school in the area. In the previous post, the photos only show vehicles parked on the sidewalks on either side of the road. They did not show the actual traffic congestion experience. The parked vehicles seem more incidental and indirect than concrete evidence of congestion brought about by school traffic generation though they are a definite manifestations of parking generation, which is directly related to traffic generation.
Parked vehicles on the sidewalk are seen as we approached the tail of a very slow moving platoon owing to the congestion generated by an exclusive school.
Traffic jam with road capacity reduced by the parked and standing vehicles along the EDSA-bound side of Ortigas Ave. The trees are witnesses to the chronic traffic jams and help alleviate their impacts by absorbing emissions from the vehicle.
Severe congestion as we approached the school – the overpass downstream in the photo is a reference for where the school is located
The overpass bears the name of the mayor of Mandaluyong City, where this school is located and which has jurisdiction, together with the MMDA, for traffic management in the area. At the time we passed the area though, there were no enforcers in the area despite the severe congestion. Is this because they gave the responsibility (or burden) of managing traffic to the school? Perhaps there was no need to post enforcers here as congestion is a regular thing and people seem to have been conditioned with the almost daily experience.
The area at the foot of the pedestrian overpass actually functions as a pick-up and drop-off area for students of the school. As such, vehicles occupy not just the the sidewalk but also more than a lane of Ortigas Avenue. This effectively constricts traffic along this major road.
Traffic is slow along the San Juan-bound direction of Ortigas as vehicles waiting for their passengers (students of the school) are lined up and occupying the outermost and even the middle lane of the road.
This queue is not entirely attributed to traffic generation by the school but is likely due to traffic management at the EDSA-Ortigas intersection, which is signalized. If the signal setting is not optimized or if the intersection is not cleared of straggler vehicles, traffic is backed up along all the approaches to the intersection. The tall building in the background hosts DOTC’s headquarters. I wonder if our officials are taking in the congestion that occurs almost daily (weekdays) and if they are even crosses their minds how to solve this problem and others like it around the country.
Proof that congestion is along both directions of Ortigas Ave. is seen in the middle of the photo where vehicles are also backed up along the overpass ramp coming from EDSA’s northbound side. For what it’s worth, the DOTC headquarters is right along this road at the building where the 7-Eleven (sign visible in the photo) is located.
Another and even closer look of what is literally bumper-to-bumper traffic along both sides of Ortigas Avenue during the afternoon peak triggered by the exclusive school along its San Juan-bound side. Visible in the photo is the congestion along the overpass from EDSA.

School traffic impacts – issues along Ortigas Ave., Part 1
I have written about school traffic generation in this blog and have mentioned about the traffic congestion experiences along major thoroughfares due to the vehicles attracted by private schools. La Salle Greenhills (LSGH) is an exclusive school found along Ortigas Avenue and during the summer months of April and May, people passing through the stretch of the road from EDSA to the Greenhills Shopping Center are relieved that they won’t have to go through traffic jams due to the school-generated traffic. From June to early December and January to March, however, the area is almost always congested in the morning and afternoon. Such congestion is predictable since it occurs during a period when students come to school and when they are dismissed mid-day or in the afternoon.
Heading to a meeting at the DOTC from the University one morning, we decided to take an alternate route. Instead of EDSA or C5, we took East Ave., Tomas Morato Ave., Gilmore Street and then emerged at the westernmost end of Ortigas in San Juan. It was already 9:00 AM when we arrived at the section most affected by the traffic generated by LSGH and so we didn’t to get caught in a jam as we proceeded towards our destination. We were proven right as traffic was almost free-flowing, and I took advantage of the traffic conditions and to take a few photos of the indicators for the potential traffic congestion in the area. The following photos also show a serious parking problem and (sadly) the usurpation of space from pedestrians. For shame!
School service vehicles parked along the sidewalk along Ortigas Avenue – beyond the wall on the right is Wack-wack, a high-end residential subdivision named for the sound of golf clubs swinging at its famous course.
Private vehicles parked along the same sidewalk – noticeable in the photo is the pink line drawn by the MMDA to supposedly demarcate space that should not be obstructed and instead allocated for pedestrian use. It is clear in the photos that pedestrians would have to walk along the edge of the sidewalk or the outer lane of the carriageway itself, increasing the risks for them to get sideswiped by motor vehicles.
More parked vehicles along Ortigas Avenue, mostly private vehicles that are highly likely owned by those studying at LSGH.
It’s actually worse on the other side of Ortigas Ave. as vehicles occupy a lane of the carriageway, effectively reducing capacity along this stretch of the road.
It seems the main purpose of the pedestrian overpass is to allow students to safely cross the street to get from and to their vehicles. I can only imagine the congestion caused by drop-offs and pick-ups along Ortigas Ave., which for certain times of the day functions as a driveway for the school.

Sales Bridge repairs completed
The repairs to Sales Bridge, which connects the Fort Bonifacio area to Villamor and the NAIA terminal complex, has been completed and all lanes along the bridge are now passable. The bridge has been a bottleneck for some weeks as repair works have led to serious traffic congestion in the area, particularly along Sales Road that’s among the main access roads to NAIA, particularly Terminal 3, which is at the end of the road and along Andrews Avenue. From another perspective, the bridge is also a main access route to Fort Bonifacio (and Bonifacio Global City) and Makati (via Pasong Tamo Extension) via Lawton Avenue, of which the bridge is a part of. I took a couple of photos while en route to T3 clearly showing all lanes open to traffic.
Under the Skyway, traffic flows smoothly on either side of the bridge. When the bridge was being repaired, only 3 lanes were available to traffic – one westbound and two eastbound.
Mixed traffic along the Sales Bridge includes trucks and bicycles. Further downstream is a roundabout at the intersection of Sales Road and the West Service Road along the South Luzon Expressway. Also, shown in the photo is the Skyway ramp connecting the tollway to the Villamor and the NAIA terminal complex.

Road congestion around NAIA: Sales Bridge
A particularly urgent problem concerning traffic congestion is the case of the Sales Bridge along the Sales Road at the Nichols/Villamor Air Base area. The bridge and the road is the main access from Fort Bonifacio and the Taguig/Makati areas and is used by most vehicles going to or coming from the airport not using EDSA and Tramo. That’s practically much of the airport-related traffic from Quezon City, Pasig, Marikina and Rizal Province. There’s usually also traffic congestion along Tramo from EDSA but this is predictable and the reason why more people tend to use the route via Sales Bridge. Nowadays its pretty bad in the Villamor area and this has been an inconvenience to a lot of travelers.
It’s been more than a couple of months now since repair/rehabilitation works for the Sales Bridge began and there are only a single lane bound for the west-bound direction and 2 lanes for the east-bound side. From the last time I passed through the area, it seems that the work on the bridge will be taking more time to complete and so more people will have to endure the inconvenience of congestion in the area. There are not so many options for traffic re-routing but I believe traffic enforcers at the intersection of Sales Road and the West Service Road should prioritize traffic bound for or coming from the airport considering the latter being a major gateway not just for Metro Manila but for the country.
Vehicles queued along the east-bound side of Sales Road. The blue wall on the right is the fence of Villamor Air Base. The overpass on top is the access ramp for the Skyway.
2At the junction, where there is a roundabout for traffic coming from the airport, Sales Bridge and the West Service Road of the South Super Highway, traffic is all tied up and you can usually hear a lot of honking among motorists whose patience have been tested by the traffic jam.
While there are traffic enforcers posted at the intersection to manage traffic, they can only do so much given the capacity of the bridge. The volume of traffic from the airport and the service road can usually overwhelm the enforcers but they should try to establish priority for traffic. It seems that the west service road is usually given more priority than the traffic to and from the airport. This should not be the case here considering NAIA is a main gateway to Metro Manila and the country.

School traffic generation – Part 3: LSGH and Ortigas
Was at the DOTC for a meeting and couldn’t help but look out the window from the conference room while waiting for the meeting to start. Our meeting was being held at the 16th floor of the building housing the Department and so it gave an excellent vista of the surrounding area. I was particularly interested in a view of Ortigas Avenue know there was no congestion that time of the day mainly because school was still off. The latter observation is important here because La Salle Greenhills, which is just a stone’s throw away from the building, is a major traffic generator with cars and school service vehicles clogging up the stretch of Ortigas Ave. from Galleria to the Greenhills Shopping Center. In fact, one can find vehicles parked or waiting along the road and even on the sidewalks, depraving pedestrians the proper and safe space to walk.
Free-flowing traffic along Ortigas Ave. in front of LSGH on a Friday mid-afternoon.
Main gate and pedestrian overpass at LSGH – there seems enough space for a multi-level parking lot inside the school but perhaps there are other options other than low capacity transport for the students.
Impact area – photo showing LSGH in the foreground and the Greenhills area in the background, including Virra Mall on the upper left and the condominiums around the Greenhills Shopping Center and behind Camp Crame.
Exclusive roads – the photo above seems the same as the previous one. A distinction though is that it shows Holy Cross Street (at right in the photo), which is inside Greenhills East Subdivision, an exclusive residential subdivision. The road and other streets in the subdivision are not open to general traffic and so cannot ease traffic along Ortigas Ave during congested periods.
Greenery – across LSGH is Wack wack, one of the first golf courses in the country and a welcome patch of green in the middle of the metropolis. Trees also line up along Ortigas Ave. but their capacities to absorb the CO2 produced by motor traffic are not enough considering the volume and frequent congestion along the road.

Caught (up) in traffic
