There are actually a lot of data available on mobility if you know how to look for them. One good source is Apple. Yes, Apple has access to thousands of smart phones that allow them to track individuals (oh you didn’t know that?) movements. Here is the link to Apple’s data:
And here is a graph showing mobility trends in the Philippines from that resource:
Some politicians and political appointees are now saying that we are in this predicament about COVID-19 because of a lack of discipline. That is bullshit. Many stayed home and/or reduced their movements. And then there’s that study showing 90% wore masks when they go out. No, it’s not lack of discipline that’s the problem but the lack of essential services and goods that are supposed to be delivered by those who are suppose to govern and the deficiencies from the start in addressing the spread of the virus especially from abroad. Perhaps these people criticizing Filipinos should look at their mirrors more closely and look left, right and across from they comfy seats to see what’s wrong with the way government has been handling the pandemic?
An article came up where the author explains the similarities of the coronavirus spread to the spread of traffic congestion. It is basically about modeling (and simulating) the spread while considering factors like the characteristics of the virus that are similar to traffic. I’m posting/sharing it here for future reference/reading:

We start April with a nice article from Cities of the Future. The article explains how traffic patterns will be changing due to Covid-19. They have already changed for most of us who have to deal with quarantines and lockdowns. And we should not expect things to go back to normal. “Normal” here, of course, is “Business As Usual” or was that. It is quite clear that we cannot and should not go back to BAU and it is probably going to be good for most of us. There will definitely be a lot of adjustments and sacrifices especially for commuters who have been dependent on cars for travel. The transport industry, too, will have to deal with the new supply and demand dynamics. And government should be up to the task of engaging and rethinking how policies and regulations should evolve to address issues coming out of the “new normal” in transportation.
Valerio, P. (2020) Traffic patterns are going to drastically be very different, says Micromobility expert , Cities of the Future, https://citiesofthefuture.eu/traffic-patterns-are-going-to-drastically-be-very-different/ [Last accessed: 4/3/2020]
En route to Batangas the other day, we had to endure severe traffic congestion along C5 and SLEX. C5 was at its worst as it took us about 2 hours from Blue Ridge until SLEX. Descending from the flyover to SLEX, we were greeted by crawling traffic along the tollway, which was to us a slight surprise for the southbound direction. Normally, traffic would already be lighter compared with the northbound side that carried peak hour travelers inbound for Metro Manila.
Much of the ‘additional’ congestion along SLEX is attributed to the ongoing construction of the Skyway extension. Traffic management is particularly criticized and congestion very atrocious at Alabang on ground level beneath the viaduct. Buses are prohibited from using the viaduct and the traffic schemes have contributed to severe congestion. Through traffic along both sides of the tollway have been affected, too, with queues reaching Laguna.
Preview: Passing the Alabang area, we observed that the queue from Alabang already stretched beyond what is visible to the eye.
No end in sight: this is what we usually describe as a traffic jam condition with the density reaching its maximum value and speed at its lowest. Volume approaches zero for this case.
Horizon: The queue that morning reached the Southwoods exit of the SLEX. Approaching northbound travelers would have to endure severe congestion until Alabang.
On hindsight, I thought that we should probably have opted to fly between Quezon City and Lipa City. My colleague said that the contact person offered that option to us but that he turned it down because he gets dizzy riding helicopters. I wouldn’t know as I’ve never ridden on one. However, we also thought it wouldn’t be prudent for us to ride a helicopter from the university. It would seem to be the transport of VIPs and easily attracts unwanted attention. Yet, it would have been the more practical and speedy if not the less expensive option for the trip that day.
There is a collage of two photos, one taken in 1975 and another in 2019, showing buses that managed to squeeze themselves into a jam. The 1975 photo was taken at the ramp of the overpass near Liwasang Bonifacio (Quiapo, Manila). There is a commentary describing the photo that attributes ‘monstrous daily traffic jams’ to the behavior of Filipino drivers. Special mention was made of public transport drivers and the photo showed proof of this. This was 1975 and motorization had not reached the levels we are at now so the
The problems pertaining to driver behavior persist today and probably even worsened along with the general conditions of traffic in Philippine roads. I say so since the volume of vehicular traffic has increased significantly from 1975 to the present and there are much more interactions among vehicles and people that have led to a deterioration of road safety as well. Traffic congestion and road crashes are asymptomatic of the root causes of most of our transport problems. And so far, it seems we have had little headway into the solutions. The photos speak for themselves in terms of how many people can easily put the blame on poor public transport services despite the fact that cars are hogging much of the road space. And what have authorities done in order to address the behavioral issues that lead to these incidents?
Someone joked that the guy in the 1975 photo who appeared to be posing in disbelief of what happened is a time traveler. The 2019 photo shows a similar guy with a similar pose though with more people around. Maybe he can tell us a thing or so about what’s wrong with transportation in the Philippines and provide insights to the solutions to the mess we have.
I saw a recent post about a meeting hosted by Pasig City. The Mayor of Pasig City recently held a meeting where he invited the mayors or Antipolo, Cainta and Taytay to discuss, among other things perhaps, transportation along Ortigas Avenue. Ortigas Avenue is a corridor shared by several LGUs most notably the Rizal towns of Antipolo (which is the provincial capital and a highly urbanized city), Cainta and Taytay. The latter two are among the richest municipalities in the country; a fact I underline here since that also should translate to them having the resources or means to help come up with transport and traffic solutions.
Morning rush traffic starts very early these days. This photo was taken around 6AM on a Thursday along the westbound direction just after the Manggahan Bridge. The pedestrian overpass at C. Raymundo junction is shown and the dark colored buildings are at Robinsons’ Bridgetown development. Note the commuters along the right waiting for a ride.
Photos paint a thousand words. The Taytay Mayor attended the meeting. He has been under fire for the horrendous traffic caused by the mismanagement of Tikling Junction as well as the Barkadahan Bridge area that was and is supposed to be a major alternative route for Rizalenos heading to their workplaces in Makati and BGC. More recently, there were posts about the traffic signals installed at Tikling Junction that basically invalidates the roundabout concept for the junction. The result last Thursday, the first day of operations for the signals, was hellish traffic that backed up a couple of kilometers along the Manila East Road and Ortigas Ave. Extension (some reports say until Cainta Junction). This, even as the signal settings were supposedly done with help from the MMDA.
Antipolo was represented by its former Mayor and husband to the current one. He also happens to be a former Governor of the Rizal Province and likely to run again as his mother, the current governor, is on her 3rd term. It seems to me that the province is not so interested in solutions for Ortigas Avenue despite most of its constituents traveling through the corridor to get to their workplaces and schools. Marcos Highway is not the main corridor for Rizal towns as it basically carries only Antipolo and maybe some of Tanay (via Sampaloc) traffic. Ortigas Avenue Extension branches into two major roads from Tikling – Ortigas Ave Extension, which ends at the capitol, and the Manila East Road, which connects to practically all of Rizal towns with San Mateo and Rodriguez (Montalban) being the exceptions. It is time for the province to pay attention to this commuting problem experienced daily by her constituents.
The Mayor of Cainta seems not as interested as the others, sending a representative who appears to be not one of the top officials (the traffic chief with a rank of SPO1=Master Sergeant is lower ranked than a councilor) of the Municipality to such an important meeting. In fact, he is currently now embroiled in a controversial faux pas involving himself by not wearing a helmet while riding a motorcycle. What’s more is his downplaying this and appearing to be even justifying the act. He eventually apologized but not before stating his moves. He is not new to publicity (stunts?) and knows how bad publicity still translates to good publicity especially in this days of fake news and trolls (he apparently has many on social media). He seems to forget that transport and traffic solutions for Ortigas Ave will likely benefit anyone seeking reelection or higher office in Rizal. He is on his last term as mayor and the break-up with some of his allies including his former Vice Mayor who ran against him in the last elections shows the limits of his political career. What was rumored as plans to run for Rizal governor might just be downgraded to perhaps Vice Mayor? In any case, he should show more interest and effort in finding solutions beyond traffic management and not by himself but in cooperation with others with whom his jurisdiction shares the problems with. Perhaps the initiative of the Pasig Mayor presents an opportunity for such cooperative work? Many people are very interested in this and will be watching – and hoping.
A couple of Thursdays ago, I was in the Ortigas CBD area to attend a conference on statistics. I hitched a ride with an old friend who was also going there and so we had some time to catch up on life and other topics we usually talked about since our college days. Being on the passenger seat also meant I had some opportunities to take photos of the traffic situation in the vicinity of the venue of our conference. Here are some photos I took of traffic in the Galleria – ADB area as we drove along ADB Avenue.
Congestion along ADB Avenue across from Robinsons. The ADB building is shown ahead of the vehicles.
Most of the vehicles turned out to be turning towards Guadix and headed for Poveda. These are traffic generated by the exclusive school where most if not all students’ mode of transport is by car. This causes much of the congestion in the area at this time of day as well as during dismissals in the noontime and afternoon.
Vehicles bound for Poveda (building is in the background) and EDSA.
View of Ortigas bound vehicles filed along Sapphire Road – this photo was taken at the bridgeway connecting Crowne Plaza and Holiday Inn. The relatively uncontested road is the Robinsons’ driveway.
The photos show how dependent to cars many people working in the Ortigas CBD are. Many of them live outside of the CBD including those residing in the Rizal towns to the east of Metro Manila. The number of people using their own cars put so much strain on the major thoroughfares including and perhaps especially Ortigas Avenue, which serves as a main arterial connecting the CBD to many parts of Pasig, Quezon City (via C5) and the very progressive towns of Rizal Province such as Cainta, Taytay and Antipolo City.
It is a wonder why up to now, there is no mass transit system along Ortigas Avenue when the demand is very high and continuous to increase with the development of lands along it. SM, Robinsons and Megawide are among the major players now developing their plots of land to become high density commercial/office/residential areas. And these will surely translate into more trips generated and worse traffic congestion. Perhaps the mayors of Pasig, Cainta, Taytay and Antipolo plus the governor of Rizal can get together to discuss and agree about solutions where each LGU can contribute for the betterment of their constituents’ commutes?
The Barkadahan Bridge is currently undergoing rehabilitation. To be accurate, the old bridge is being rehabilitated and upgraded/retrofitted to be able to carry the traffic projected to use it being a vital link between the Province of Rizal and Metro Manila via Pasig and the C-6 corridor. The bridge is named after the “friendship” established among Rizal municipalities and Pasig City for an area that has been subject of a territorial dispute among them. These are the municipalities of Cainta and Taytay (Rizal Province) and the city of Pasig. The bridge spans the Manggahan Floodway, much of which is in Pasig City.
To increase the capacity for this crossing, which is the most direct route to C-6 and popular among many headed to Taguig/BGC and Makati, a new bridge had been constructed to the south of the old one. The older one had 2 traffic lanes and was no longer sufficient for the volume of vehicles crossing it after the expansion of C-6 resulting to it steadily gaining more users over the years. Use of this route cut down travel times between Rizal and BGC and Makati by at least 30 minutes based on our experiences using the route.
Late last year as far as I could recall, the new bridge opened and immediately increased capacity but then congestion quickly set-in due to two factors: the traffic management at the intersection with the East Bank Road and the constrained (two-lane, two-way) leg of Highway 2000. Add to this the lack of discipline by local traffic in the form of tricycles and motorcycles counter-flowing in the area.
Earlier this year, signs were posted around Rizal about the then impending project for the rehabilitation of the old bridge. The signs advised for most travellers to avoid using the Barkadahan Bridge due to the congestion in the area because of the project. It turns out that what was thought by most as a project retrofitting the old bridge alone was actually a bigger one involving increasing the capacity of the Highway 2000 leg of the intersection with the East Bank Road. Following is a photo posted at the official Facebook page of the Rizal Provincial Government showing the demolition of buildings and other structures along the Highway 2000 leg. The photos were taken from the new Barkadahan Bridge approaching the intersection, the southbound direction of the East Bank Road, and from the westbound side of Highway 2000.

From the photos above, it is clear that at least 2 lanes will be added to Highway 2000 and that this leg will soon be well-aligned with the Barkadahan Bridge, which will also have a total of 4 lanes. Hopefully, this project will be completed soon and within the year (before December?) in order to alleviate the commuting woes of Rizalenos working in the BGC and Makati CBD areas. Of course, that goes without saying that there is also a need to optimise the traffic signals at the intersection and to strictly enforce traffic rules and regulations vs. erring motorists in the area.
The rehabilitation of the Marcos Highway Bridge in Marikina has necessitated traffic management schemes at the bridge itself and along alternative routes to alleviate congestion in the area. These are collectively called traffic or transport systems management (TSM) schemes with the objective of optimising existing infrastructure and resources without necessarily building something entirely new. These are quite different from travel demand management (TDM) schemes that include number coding and truck ban policies that are already being implemented (though Marikina does not implement the number coding scheme).
Traffic build-up at the approach to the intersection with FVR Road (To Riverbanks). This is now a signalised intersection as traffic from Blue Ridge/White Plains is now allowed to cross to FVR Road.
Using the route via FVR Road (Riverbanks) means you don’t have to cross the Marcos Highway Bridge and travellers will merge with those who crossed the bridge just before the Line 2 Santolan Station.
In the mornings, one lane each is allocated for either the eastbound or westbound traffic. That’s practically a total of 3 lanes (+2 lanes westbound for the SM Marikina Bridge) for the westbound direction and a single lane for the eastbound side. This is logical given the directional distribution of traffic at this time of day and the alternative routes already available to travellers.
Here are a few photos taken on a night time drive. Note that this was taken by a passenger. Don’t even try doing this (taking photos) while driving a vehicle, and especially not while on a motorcycle.
Entrance to the bridge right after Maj. Dizon – this part is not affected by the rehab works but vehicles position themselves to shift towards the left side, which is the usable part of the bridge.
Both lanes of the westbound side of the bridge are used for eastbound traffic. Westbound traffic are all along the SM Marikina bridge for a total of 2 lanes each for either direction of flow. The cones are not removed for practicality since they would have to be installed for the morning when one lane is allocated for the westbound traffic.
Vehicles shift to the right to return to the correct lanes for eastbound traffic along Marcos Highway at the Santolan area. Note the westbound vehicles shifting towards the underpass and SM Marikina on the left.
The Marcos Highway Bridge was scheduled for rehabilitation in the next four months starting last week. While it will not be totally closed to traffic, the scheme reducing its capacity will surely lead to congestion along Marcos Highway. This congestion should be expected along other roads as well, as travellers, particularly those taking private transport will be using alternative routes in order to avoid this area. Those coming from the east will likely go through Marikina City via the parallel route comprised of Sumulong Highway and A. Bonifacio Avenue. Others will turn to A. Rodriguez (Ligaya). And perhaps others may go via Ortigas Avenue Extension. These alternative routes correspond to the other bridges crossing the Marikina River connecting the Rizal province and part of Marikina and Pasig to Metro Manila.

I will write more on this topic once I get more information on what’s happening to the traffic in the area. Meanwhile, I do know that my usual alternative route via Marikina and Tumana seems to have more than the usual traffic during my commute. While it is easy to attribute this to the partial closure of the Marcos Highway bridge, this could also be just a normal variation in the typical daily traffic for that route.
