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.

Traffic congestion due to waterworks and roadworks
Driving from the airport this morning, I already saw the buildup along Villamor due to some roadworks being undertaken along the overpass crossing the SLEX. As such, I decided to take an alternate albeit longer route via Tramo and EDSA on my way back to Antipolo. It would have been longer but I had assumed Tramo and EDSA would be free-flowing at 7 AM on a Saturday. I was wrong!
Tramo congestion – Tramo is usually congested due to a variety of reasons including provincial buses maneuvering to and from terminals and depots located along the EDSA-bound side of the road and the proliferation of tricycles and pedicabs operating along the road despite the clear ban against them on national roads. The latter serve the informal settlers who live along Tramo (and Pasay), even occupying parts of the waterways in the area. This morning, waterworks by concessionaire Maynilad added insult to the injury that is congestion along the road. Airport-bound traffic wasn’t so lucky, too, as they had to contend with what seems to be a flawed setting of the traffic signal at the intersection downstream.
More traffic – after passing the Maynilad work site, there was still much congestion and it turned out this was due to very slow turning (i.e., all vehicles must turn right upon reaching EDSA) as MMDA traffic enforcers were not doing their jobs to ensure the intersection was clear of buses, jeepneys, taxis, and tricycles and pedicabs loading and unloading after the intersection, along which provincial bus terminals were all lined up. That’s right. There are tricycles and pedicabs along EDSA. I would have taken photos of the situation but unfortunately, these have to be against the sun and my trusty cell phone could not manage to get good photos. Such congestion is supposed to be manageable if enforcers would just be strict/firm in doing their jobs.
EDSA traffic – after recovering from the congestion along Tramo and the stretch of EDSA from Tramo to Magallanes, I stumbled upon another buildup as I passed Guadalupe and crossed the bridge at the Pasig River.
Re-blocking – it turned out that the congestion was due to roadworks along a lane of EDSA, which practically occupied 2 lanes due to the equipment and temporary barriers set up in the area near Reliance and the Boni MRT-3 Station.
Hectic schedules – I forgot that the re-blocking works along EDSA and other major roads in Metro Manila are undertaken during the weekends when traffic was supposed to be relatively light compared to the weekdays. As such, the MMDA only allows DPWH and its contractors to conduct works during the weekends, targeting completion by Sunday night in order for the lanes to be usable by Monday.
Imelda Avenue again – as if the congestion along Tramo and EDSA were not enough for a Saturday morning, I encountered still another bottleneck along Imelda Avenue in Cainta. This was quite surprising to me as water works in the area were supposed to have been completed more than a month ago.
Surprise! surprise! – what I thought was a completed project turned out to be something that was stalled for some reason. I think this may also be related to a similar policy being applied to the contractors, restricting their work to weekends.
There must be a better way to manage traffic along work sites like the one above? Perhaps work should not be limited to the weekends but be allowed during the late nights to early mornings (11PM to 5AM). This would allow for more time to be available for contractors to complete projects especially during these months of April and May when school is out and weather (read: rains) is not necessarily a factor working against such road and water works. While it is really difficult to work under the scorching sun, it is still no excuse for enforcers to do their jobs right in managing traffic to ensure smooth flow. It is a wonder how we cannot impose discipline on erring drivers at the cost of valuable time and fuel to other travelers.

Marcos (Highway) pa rin!
The traffic conditions along Marcos Highway along sections within Antipolo, Cainta, Marikina and Pasig have worsened the past two weeks due to the ongoing roadworks that have resulted in traffic jams very early in the morning (e.g., congestion at 5:30 AM) and until late at night. This, as the contractor appears to be rushing to meet the March 2012 deadline indicated in the DPWH project postings along the highway. So much for so-called traffic management along construction sites! I believe that MMDA and local government enforcers are not at all helpless in trying to alleviate congestion. I think they are not doing their jobs and they are not trying hard enough given the requirements to enable smoother flow along affected sections. Meanwhile, the contractor should also be held accountable for the congestion as valuable time is lost for many using the highway. Gumawa pa ng traffic management plan at nag-post pa sa DPWH website eh di naman pala masusunod!
While the quality of work for the pavement is not suspect (considering the contractor has done a splendid job replacing the entire pavements along the highway to ensure that the base and sub-base layers are also replaced), much is to be desired regarding the way certain sections are being selected for rehabilitation. I’m sure that most if not all motorists are inconvenienced by the challenging obstacle course comprised of excavations, fills and concrete barriers. Of course, we can just be hopeful that the project will finally be completed this summer and we will ultimately benefit in the improvements along Marcos Highway.

School traffic generation – Part 2
It’s been quite sometime since I wrote Part 1 on school traffic generation. I had been unable to get a few photos to describe congestion in another area where school trip generation frequently causes severe traffic congestion. This is along Ortigas Avenue in the Greenhills where another private school generates so many vehicle trips that it is able to clog both sides of the road almost every weekday of the school year. This is the case of La Salle Greenhills (LSGH), which, like Ateneo along Katipunan causes so much negative externalities with respect to traffic along a major thoroughfare.
The problem with La Salle Greenhills is more severe considering it has very limited space in its campus to be able to accommodate parking, unlike Ateneo, which has a sprawling campus (sadly, its being occupied by more cars these days). The result has been cars occupying the curbside lanes along either side of Ortigas Avenue and cars parked on the sidewalks (I have to get photos of these.). This has caused a lot of congestion during the weekdays and has so far been unaddressed by local authorities who seem to be helpless despite the fact that they only need to enforce general traffic rules to rid the streets of parked and standing vehicles. The solution is quite simple but very difficult to implement considering authorities will be up against LSGH. But then, the majority here are not LSGH constituents but the general public who are inconvenienced on a regular basis.
It took us some time to cover less than 400 meters from the EDSA-Ortigas intersection to the median opening to turn left into the DOTC driveway on the other side of Ortigas Ave.
At this point, the three lanes from the intersection narrows to 2 lanes, necessitating some jostling for position among the vehicles.
There are 3 median openings (one after the other) under the San Juan-bound overpass from EDSA-Ortigas. One slot is a U-turn slot for vehicles returning to EDSA-Ortigas, while the second is for vehicles turning back to LSGH or the Greenhills shopping district. Another opening is right after the second slot and is for vehicle turning left towards the DOTC main office.
Yes, that’s right – the DOTC main office is located in the area and LTO officers are regularly in the area due to meetings of their officials. It’s a wonder how these seem to be blind to the congestion on the ground. Perhaps the current Secretary should look into this as a test of his commitment to solving transport problems?

Weekday EDSA
I chanced upon an uncongested EDSA one day during noontime along the northbound direction. I was traveling from the airport and saw that my usual route along C5 was very congested. I decided to take EDSA instead considering it was noontime and there would probably be less vehicles along the highway during that time of day. I was right and the following photos speak for themselves in as far as describing traffic between 12:00 NN and 1:00 PM.
Section past Orense Street and the MMDA headquarters
Section approaching Guadalupe
Guadalupe Bridge, crossing the Pasig River, the MRT 3 runs along the steel bridge above
Approaching A. Bonifacio/Renaissance, in the background is the G.A. Tower, the Boni MRT Station and condos under construction including SMDC’s Jazz
Section across the Renaissance Tower where many FM radio stations are based
Section past Robinsons Cybergate Mall
Section across the SM Megamall and approaching the ADB
Section across the ADB and approaching Ortigas Ave. One of Galleria’s buildings is seen behind the giant billboards. The MRT
Section descending the Ortigas Flyover and across from Corinthian Gardens
Section across Camp Aguinaldo (between the Aguinaldo and Crame) and approaching the Camp’s EDSA gate
Section approaching Boni Serrano Avenue
Section approaching the EDSA underpass crossing P. Tuazon and approaching the Cubao commercial center
Section past the Cubao commercial center and across from several provincial bus terminals lined up along EDSA northbound
Section approaching Kamias – taking the flyover means I won’t be able to turn towards East Avenue so we shifted towards the outer lanes
Now, if only EDSA and the other main arteries of Metro Manila could be like this more frequently…

Caught (up) in traffic
