On civil works for transferring cables and wires underground
I got messages this week about the civil works to be implemented in relation to transferring overhead cables and wires underground at the Ortigas Center in Pasig City. This is a screenshot of what’s been circulating the past days:
I think this follows the examples of cities like Iloilo and Davao already transferring or placing power and communications cables and wires underground. Prior to these, Bonifacio Global City (BGC) in Taguig City already did so but that was from the start considering BGC is a masterplanned development. Other masterplanned developments are already consciously doing this so there will be no overhead cables and wires that are often criticized as unsightly or ugly. Such works will require traffic management as excavations will surely reduce road capacities and lead to more congestion. The timeline or schedule can also be affected once they do the excavations as conflicts among utilities are expected. Note that water lines and drainage are already underground and there will be the need to resolve the intersections of these with the power and communications lines to be transferred.
Perhaps we can learn from this experience that Ortigas Center will undergo until 2026 as other Metro Manila LGUs also consider transferring their overhead cables and wires underground. Quezon City, for one, is already at the early stage of identifying an area or corridor to serve as a pilot for the city. That can be a road like Commonwealth Avenue or Visayas Avenue or perhaps the Araneta Center in Cubao.

Davao 8th, Manila 14th worst in Tomtom Traffic Index
I just want to share this news report here:
Source: Davao 8th, Manila 14th worst in Tomtom Traffic Index
I have to admit that I still have to figure out in detail how exactly their data were collected and evaluated. However, knowing and experiencing traffic in these cities, I would like to opine that traffic is still worse in Metro Manila cities compared to Davao and perhaps others across the country.
From 9-to-5 to Anytime: How Telecommuting Changes the Traffic Game
Here’s a quick share of an article on telecommuting:
Source: From 9-to-5 to Anytime: How Telecommuting Changes the Traffic Game
To quote from the article:
“As we look across these 83 cities, it’s clear that remote work has brought relief to some areas while leaving others just as crowded as before. The cities seeing the most benefit from WFH were those with a flexible, remote-friendly workforce and a supportive economic structure. For fast-growing cities, or those with heavy industry or logistics, WFH alone wasn’t enough to solve congestion.
Telecommuting has no doubt reshaped our roadways, but it’s clear that tackling urban congestion will require more than just a remote work policy. As cities continue to grow and evolve, the future of urban mobility will rely on creative solutions, from smarter infrastructure to updated transit options, to keep America’s cities moving in this new, work-from-anywhere world.”
There are lessons to be learned here for us in the Philippines. Telecommuting is not a new thing here especially considering we have many BPOs operating across the country. Indeed, it is not to be considered as the only solution but one of many we can use to reduce congestion and improve commutes in our towns and cities.

Congestion due to flyover construction: Tagaytay-Nasugbu Road – Part 2
I showed photos of the construction of an overpass along the Tagaytay-Nasugbu Highway coming from Tagaytay in the previous post. This time, here are some photos taken along the opposite direction.

Congestion due to flyover construction: Tagaytay-Nasugbu Road – Part 1
There is significant traffic congestion along the Tagaytay – Nasugbu Highway due to the construction of an overpass along the highway at its junction with the Tagaytay – Mendez Highway.
Was there a need for a flyover here? Otherwise I would suggest instead a set of good old-fashioned traffic signals and geometric improvements to the intersection.

Is the MMDA’s coding scheme still effective?
That’s actually a title of a paper or article I co-wrote before. At the time, which was over a decade ago, we were revisiting certain travel demand management (TDM) measures being implemented in Metro Manila. We already concluded that the effectiveness of the number coding scheme has been reduced mainly as people bought a second, third or more vehicles to be able to use any vehicle on coding days.
Since then, coding’s effectiveness continued to be eroded by a combination of increasing vehicle ownership (including more vehicles operating as ride hails) and the rapid increase of motorcycles.
More recently, government decided to give push for electric and hybrid vehicles. The MMDA made these coding exempt, which perhaps is an example of instituting a policy with unintended consequences. I say unintended here because the agency seems oblivious to the fact that people will likely get that second, third or more vehicle. And that will be an EV or hybrid. Manufacturers are already marketing these as ‘coding exempt’ and they are making a good sales pitch here.
Maybe it’s time to revisit coding and re formulate it? But then coding wasn’t supposed to be sustained as long as it has. Government should be more aggressive and decisive for public transport in order to retain and increase mode shares that have also been reduced by more private vehicle and motorcycle use.

Technical sessions at the TSSP 2024 Conference
I am sharing here the latest draft of the technical sessions for the 30th Annual Conference of the Transportation Science Society of the Philippines (TSSP). The conference will be held in Iloilo City this coming September 13, 2024.
I will share the draft program for the morning plenary session in the next post.

Safety or speed?
We start June by sharing a video on why safety and vehicle speed are incompatible:
I saw this video while browsing an article on “Dangerous by Design”. The article discusses a new publication where road designs are evaluated from the perspective of safety. Most of our roads have been designed with speed in mind. That is, how to facilitate the movement of motor vehicles to ensure they travel faster. Forgotten or, even worse, disregarded is the most important element of safety. Why do we widen roads or insist on higher speeds in populated areas or school zones? Such questions are not addressed directly or not answered at all by agencies in charge of planning, designing, constructing and maintaining roads and bridges. The same is true for agencies or units in charge of traffic regulations or management. The result not surprisingly is an increase in the number of road crashes, fatalities and injuries due to our roads being ‘dangerous by design’.

Another roadblock for active transport?
The Metro Manila Development Authority (MMDA) recently released what they claim to be their counts of bicycle traffic along major roads in Metro Manila from 2020 to 2023.
These are supposed to be official data as it is issued by the government agency in-charge of traffic management for Metro Manila roads (aside from its other functions and roles). What are not stated, and are actually very important details, are the locations of the counts and when the counts were conducted. The Traffic Engineering Center (TEC) that was under the DPWH and currently with the MMDA used to publish traffic volume maps for major roads in Metro Manila. So along EDSA, for example, the volume per section are shown on the map. The same for other major roads like Commonwealth, Quezon Avenue and SLEX. The thicker lines mean higher volumes along those sections, and vice versa. However, they did not consciously count bicycles (only motor vehicles) and perhaps MMDA only started counting during the pandemic (i.e., 2020). So there is no one value to represent a road. And counts vary over time of day, day of the week and even throughout the year (i.e., monthly variations).
There were many reactions to the MMDA’s posting of the data and most were critical and even derided the agency for what to them appeared to be inaccurate data. The problem is that it seems there are no other counts that can validate and perhaps refute the MMDA data. Previous bike counts were not conducted according to how the MMDA and DPWH count vehicles. That is, counts are typically done over a 14 or 16-hour period and ideally on several days in a year. Expansion and conversion factors are applied based on established stations along major roads that are supposed to have more frequent if not continuous counts. This methodology is how Annual Average Daily Traffic (AADT) is computed. Call it car-centric if you like but the methodology is very much applicable to bicycles as well. Peak hour counts for bikes are not enough and the peak hour factor for motor vehicles does not apply to bicycles (if this is to be used to expand/convert peak volumes to daily values). In fact, if you go into the math, there should be a peak hour factor for each type of vehicle considering each vehicle’s volume will vary differently over time. So yes, the solution here is to conduct bicycle counts according to how MMDA or DPWH counts vehicles and these should be done along several stations along major roads (e.g., those in the table above) to validate the MMDA counts.

Counterflow irony along Ortigas Avenue Extension, Pasig City
One Friday, I traveled to Ortigas Center from Antipolo via the most direct route using Ortigas Avenue Extension. I was not surprised by the counterflow scheme being implemented starting from De Castro all the way to Rosario Bridge. I was also not surprised that the more congested lane was the counterflow lane. I thought everyone expected the main traffic lanes to be congested as PUVs like jeepneys, buses and vans usually create bottlenecks as they block traffic while passengers board/alight along that section of Ortigas Avenue Extension. Here is what you might encounter in terms of traffic if you opt to stay along the westbound traffic lanes:
Traffic before the Manggahan floodway bridge at what was generally called Mariwasa. The Filinvest residential development on the left used to be the Mariwasa tiles plant.
Traffic after the crossing the bridge. Note the pedestrian overpass in the photo.
Meters after and near the overpass, you can already see the build-up in the Rosario area
The Rosario bridge area is usually congested not just because of the PUV operations but also because there is the junction of Ortigas Avenue Extension and Amang Rodriguez Avenue, which is another major thoroughfare connecting this area to other parts of Pasig, Quezon City and Marikina City.
I will post about the counterflow scheme in Bangkok in the next post.

Caught (up) in traffic
