Traffic is back to “normal”

Traveling to the office last Monday, I could not help but notice the long lines of cars along Ortigas Avenue’s westbound lanes and Katipunan’s southbound lanes. Without adequate public transportation, people have few options for their commutes. Walking from home to workplaces is feasible only for those who live relatively near their workplace (perhaps up to 5km distance?). Cycling may be considered but not everyone can bike beyond 5km, what more for 10km+ commutes. And for both cases, there are just so many obstacles (and I’m not just fault-finding here) like a lack of sidewalks and bike paths to ensure safe walking and cycling.

Traffic congestion along Felix Avenue in Cainta towards Cainta Junction (with Ortigas Avenue Extension) – these are mostly outbound traffic likely coming from the residential subdivisions along Felix Avenue and heading to workplaces in Pasig, Mandaluyong, Makati and Taguig. They will likely take Ortigas Avenue to connect with other major roads such as C-5 and EDSA to get to their destinations.

 

The DOTr and the LTFRB have released guidelines for safety and the prevention of the spread of the COVID-19 virus. Yet, they have moved quite so slowly to bring back public transportation to address the demand for it and to be able to discourage or restrict car usage in the “business-as-usual” or “old normal” sense. Public transportation is critical if we are to transform transportation during this transition from the lockdowns. Granted, the government probably wants to use the situation to effect its modernization plans but it is one thing to take advantage of the opportunity and another to be an opportunist considering the vulnerabilities of the transport sector after it endured 3 months of shutdown. The moral and right thing to do is to bring back public transport and give incentives for it to thrive and perhaps transform or upgrade by themselves rather than force the situation at the expense of commuters.

Assessing the risk of infection from the transport safety perspective

My colleagues and I have been developing a risk assessment table for land transport modes to be submitted to the UP COVID-19 Response Team. We did a rapid assessment using mainly concepts from road safety.

The concepts are fairly simple. Risk assessment can be based on the likelihood of contracting the virus gauged from certain exposure factors. Exposure estimation may be quantitative where metrics are applied and data collected for the analysis. Estimation may alternatively qualitative based on experiences, perceptions, expert opinions, etc. but subject to logic (e.g., careful deduction). In road safety, for example, these factors may be defined as three: time, distance and volume.

Time exposure can be determined using travel time as a metric. Longer the travel times mean higher exposures for a commuter. Higher exposure translate to a higher likelihood that a person may become involved in a road crash. Thus, a commuter traveling for 1 hour, one way, will have a higher likelihood of being involved in a crash compared to another traveling only 10 minutes even assuming that both use the same mode of transport. Applied to the risk of viral infection, longer commutes may mean people can have higher exposure to potential carriers of the virus.

Distance exposure can be determined using travel distance as a metric. Longer travel distances mean higher exposures for a commuter. Higher exposure again translate to a higher likelihood that a person may become involved in a road crash. Thus, a commuter with a travel distance of 10 kilometers will have a higher likelihood of being involved in a crash compared to someone traveling only 1 kilometer. Applying this to the risk of viral infection is similar to the previous case for time exposure even when assuming the same mode of transport.

Volume exposure can be determined using both the volume of vehicles as well as the number of passengers inside the vehicles. The more vehicles or people you have on the roads interacting, the higher the likelihood of one becoming involved in a crash. It can also be argued that riding public transport in high volume, mixed traffic makes a passenger have a higher likelihood of being involved in a crash. Again, applying this to the risk of viral infection, it should be easy to understand why physical distancing is necessary in vehicles as well as outdoors when walking or cycling. It should also extend to having less vehicles on the road to further reduce the likelihood of spreading the virus.

In the real world, we cannot isolate each factor from one another. Instead, we have to contend with all three combining to create various scenarios. Along expressways, for example, the volume of vehicles might be high and so are distances. Time exposure can be lower due to high speeds. Yet high speeds can contribute to increased likelihood of crashes. Meanwhile, traffic congestion has all the ingredients for maximizing the likelihood for crashes and, by extension, viral infection. Long commutes (by time and distance) plus high volumes of people and vehicles combine to create the worst case scenario from the perspectives of both road safety and infection, which are both public health issues.

Next – Why we should not return to the old normal…

Is traffic congestion like a virus?

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:

Simon, M. (2020) “Turns Out, Traffic Spreads Like the Coronavirus”, wired.com, https://www.wired.com/story/traffic-spreads-like-disease/?bxid=5bd6761b3f92a41245dde413&cndid=37243643&esrc=AUTO_OTHER&source=EDT_WIR_NEWSLETTER_0_DAILY_ZZ&utm_brand=wired&utm_campaign=aud-dev&utm_mailing=WIR_Daily_040720&utm_medium=email&utm_source=nl&utm_term=list1_p2 %5BLast accessed: 4/8/2020]

 

SLEX congestion

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.

The problem with public transport in the Philippines…

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.

Traffic congestion due to Barkadahan Bridge rehab

Here are more photos of the situation in the vicinity of Barkadahan Bridge. Photos were taken on a late Sunday morning (around 11 AM). Photos show the traffic congestion particularly along the eastbound side of Ejercito Avenue and Barkadahan Bridge.

Even before completely crossing the bridge, one can see how long the queue from C-6 is. This is a photo of the queue just past the West Bank Road. The road here is names Ejercito Avenue after former Pres. Joseph Estrada whose real family name is Ejercito.

Truck occupying an entire lane and encroaching on one of the lanes to C-6. This is due to the bottleneck caused by the wall of a residential subdivision across from the Greenwoods gate. The wall actually only contains the subdivision name and yet DPWH has been unable to expropriate the land that includes part of that subdivision’s driveway.

Long queue extending towards Tapayan Bridge along Ejercito Avenue

Queue along Tapayan Bridge or bridges considering there are two – one for each direction of traffic.

Queue crossing the bridge and the bend towards C-6 and Lupang Arenda, which is a major relocation site for Metro Manila squatters during the time of then Pres. Joseph Estrada. Vehicles turn left towards C-6 while those going straight continue along Ejercito Avenue towards Pinagbuhatan, Pasig City.

The queue reaches C-6 on a Sunday morning. It is likely worse on weekdays.

Status of Barkadahan Bridge, Taytay, Rizal

I recently wrote about the Barkadahan Bridge and its current state and compared it to the Marcos Highway Bridge that is now completed and fully opened to travelers. Unfortunately, I didn’t have photos to share but only shared my observations based on what friends have told me and what I’ve read on social media (i.e., Rizal Provincial’s and Taytay’s official Facebook pages) about the situation there. I finally had the opportunity last Sunday when I went to fetch my family at the airport. Here are photos of the Barkadahan Bride and its environs. Note that Barkadahan is actually two bridges and not one. The new one is currently being used for two way traffic (one lane each) while the second one is under rehabilitation and retrofitting. The latter  had and will have 2 lanes, too.

Approach to the Barkadahan Bridge via Highway 2000 – notice the widening on the south side of the highway? That’s the ROW expropriated to align the bridge(s) with the highway. Ultimately, this should be of the same width as C-6. 

Closer to the bridge, you see more of the ROW acquired to improve the geometry for the area and the intersection with the East Bank Road. Highway 2000 is now aligned with the second (newer) bridge constructed that will eventually carry only the eastbound traffic. The older bridge currently being rehabilitated and retrofitted will carry the westbound traffic. 

Vehicles crowd on the two-lane bridge that is the new Barkadahan Bridge. The old one is currently being rehabbed. Notice the significant volume of trucks using the bridge? This is expected to increase due to the industrial developments in Rizal Province and along C-6, and the direct route this corridor provides towards the SLEX via Bicutan.

Big sign at the bridge – there are many of these scattered around Pasig and Rizal advising travelers against using the route and Barkadahan Bridge because for the construction work on the bridge. This ‘avoidance’ basically transferred (some say returned) much of the traffic to Ortigas Avenue Extension. Many if not most users of the bridge use this alternate route to travel from Rizal to BGC and Makati CBD.

A peek at the construction work on the old bridge – note that the contractor seems to have completed installing the steel reinforcement for the slabs for this section of the bridge. The next phase would be the concrete pouring.

Still another peek showing the extent of the work on the old bridge – my casual observation of the work areas was that there seems to be not so many workers. But then maybe it was a Sunday? Perhaps there should be more people working considering this is a very urgent project?

Tricycles, motorcycles and bicycles – there’s a lot of local traffic using the bridge and these are represented by mostly tricycles serving the residential and commercial areas along the East and West Bank Roads and the cyclists you most often see crossing the bridge. Most motorcycles are through traffic. On weekends one can observe more recreational cyclists as this route is a popular one to Rizal and particularly its mountainous areas that are popular to mountain and road cyclists.

Counterflow – many motorcyclists tend to counterflow and this adds to the friction and slows down traffic. Once the other bridge is completed and re-opened, these will likely be reduced to lane splitting or filtering as the opposite flows of traffic will be assigned to separate bridges. Counterflow traffic will then be very obvious and should be apprehended.

Here’s the resulting queue on the other side of the bridge. This is severe congestion that reaches C-6. Note that the photo was taken on a Sunday. Perhaps these travelers have no other option but to use this route so they are stuck in hellish traffic on a Sunday? I can only imagine how worse it is on weekdays.

As a parting shot, I think there are still a couple of things that need to be addressed once the bridges are both open to traffic:

  1. Optimizing traffic management at the intersections with the East Bank Road and West Bank Road of Manggahan Floodway – the (mis)management of traffic here also contributes to congestion in the area. Traffic enforcers on both ends of the bridge have basic knowledge of how traffic must be managed and end up with the “buhos” approach. They don’t seem to be coordinating with each other, too. Their approach also heavily favors the East and West Bank roads when traffic is heavier along the main corridor that is C-6/Highway 2000. There needs to be a more efficient way to manage traffic here and that may be in the form of a sophisticated traffic signal system at least for the two intersections. Settings need to be studied and signals have to be adaptive to the variation of traffic throughout the day.
  2. Resolve bottlenecks in the area including structures that tend to reduce capacities of the approaches to the bridge.

More on this topic soon!

Cooperative work among LGUs to address transport problems along Ortigas Avenue Extension?

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.

Is there really a transport or traffic crisis in Metro Manila?

I was interviewed recently for a research project by students enrolled in a journalism class. I was asked by one in the group if we indeed have a transport crisis in Metro Manila. The other quickly added “hindi transport, traffic” (not transport but traffic). And so I replied that both terms are valid but refer to different aspects of the daily travel we call “commuting”. “Traffic” generally refers to the flow of vehicles (and people if we are to be inclusive) while “transport” refers to the modes of travel available to us.

“Commuting” is actually not limited to those taking public transportation. The term refers to all regular travel between two locations. The most common pairs are home – office and home – school. The person traveling may use one or a combination of transport modes for the commute. Walking counts including when it is the only mode used. So if your residence is a building just across from your office then your commute probably would be that short walk crossing the street. In the Philippines, however, like “coke” and “Xerox”, which are brands by the way, we have come to associate “commute” with those taking public transportation.

And so we go back to the question or questions- Do we have a transport and traffic crises? My response was we do have a crisis on both aspects of travel. All indicators state so and it is a wonder many including top government transport officials deny this. Consider the following realities for most commuters at present:

  1. Longer travel times – what used to be 30-60 minutes one-way commutes have become 60 – 120 (even 180) minute one-way commutes. Many if not most people now have double, even triple, their previous travel times.
  2. It is more difficult to get a public transport ride – people wait longer to get their rides whether they are in lines at terminals or along the roadside. The latter is worse as you need to compete with others like you wanting to get a ride ahead of others.
  3. People have to wake up and get out of their homes earlier – it used to be that you can wake up at 6:00AM and be able to get a ride or drive to the workplace or school at 7:00/7:30 AM and get there by 8:00 or 9:00AM. Nowadays, you see a lot of people on the road at 5:30AM (even 4:30AM based on what I’ve seen). That means they are waking up earlier than 6:00 AM and its probably worse for school children who either will be fetched by a service vehicle (e.g., school van or bus) or taken by their parents to their schools before going to the workplaces themselves.
  4. People get home later at night – just when you think the mornings are bad, afternoons, evening and nighttimes might even be worse. Again, it’s hard to get a ride and when you drive, traffic congestion might be at its worst especially since most people leave at about the same time after 5:00PM. Coding people and others not wanting to spend time on the road (instead working overtime – with or without additional pay) leave for their homes later and arrive even later.
  5. Less trips for public transport vehicles – traffic congestion leads to this. What used to be 6 roundtrips may now be 4. That affect the bottomline of income for road public transport providers. Given the increased demand and reduced rolling stocks of existing rail lines that includes rail transport.

To be continued…

Ortigas Center congestion

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?
