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.

Solar road studs for Ortigas Avenue Extension bike lanes
The bike lanes along Ortigas Avenue Extension now have solar road studs for these to be more visible at night time or when it is dark. Following are photos of the bike lanes at night.
While the studs enhance the visibility of the bike lanes and perhaps also the safety of cyclists, the latter is not assured. The bike lanes are not protected and physical barriers like those installed along Quezon City roads are most effective in ensuring the safety of cyclists against motor vehicles. The solar studs do not deter motor vehicle drivers from encroaching on the bike lanes so they appear to have minimal impacts on safety.

Bike lanes along Ortigas Avenue Extension, Cainta, Rizal
The bike lanes along Ortigas Avenue end at the border of Pasig City and Cainta (or Metro Manila and the Province of Rizal). This is just after SM East Ortigas if you are eastbound, headed towards Cainta Junction. Last Friday, I was able to take a photo of the newly painted bike lane along Ortigas Avenue Extension’s eastbound side but which starts just after Cainta Junction across from the main gate of Brookside Hills Subdivision.
The new bike lane along Ortigas Avenue Extension used luminous paint, which makes it glow at night especially when exposed to vehicle headlights.
There have been bike lanes in Rizal prior to this development. Marcos Highway and Sumulong Highway have painted bike lanes. The Manila East Road from Tikling Junction also has bike lanes. This ‘missing link’ between the boundary of NCR and Rizal and Tikling is long overdue. Hopefully, this will encourage more active transport users particularly from “bike to work” and “bike to school” trips.

Bike lane master plan for Metro Manila, Metro Cebu and Metro Davao
The Department of Transportation (DOTr) with support from the United Nations Development Program (UNDP) yesterday formally launched the Bike Lane Master Plan for Metro Manila, Metro Cebu and Metro Davao. Yesterday’s event was actually the third and last leg of presentations, which were also made in Cebu and Davao. Here are a few photos I got from the DOTr Facebook page (these are public):
Printed copies of the master plan were distributed to attendees (Photo: DOTr Facebook page)
Dr. Ricardo Sigua of the National Center for Transportation Studies presented the highlights or key features of the master plan. The UNDP engaged NCTS to conduct the master planning project for DOTr. (Photo: DOTr Facebook page)

While the master plan is most welcome as the country continues to build infrastructure for active transport (mainly walking and cycling), the launch is actually one year late. The project was actually completed last year and though most of the recommendations have yet to be carried out, many items including the inventories are already dated. These master plans though should not be static documents but dynamic in these sense that it would have to be updated regularly. For one, updates would provide the opportunity to reinforce or improve certain aspects of the plan. Updates also provide an opportunity to check whether progress is being made on the targets set in the plan. Also, since the master plan is for three metropolitan areas perhaps it can be part of the foundation for a nationwide plan. However, many plans fail if there is not support or scarce resources allocated for the implementation. Thus, there is a need for resources or allotments especially coming from government to support the realization of the plan.

Quezon City’s bike ramps
This is a very late post on bicycle facilities. I took a few photos of the bike ramps Quezon City installed on the stairs of pedestrian footbridges in the city. I am sharing a couple of these photos here for reference.
The bike ramp allows one to roll his/her bicycle with relative ease up and down the footbridge. Otherwise or without the ramps, cyclists would have to carry their bikes up and down the stairs.
The landing for the the bike ramp at the foot of the stairs.
It’s quite obvious in the photos that the space along the stairs is quite constrained. Ideally, perhaps there should be two ramps – one for going up and another for going down. One ramp means one cyclist will have to wait for another or others to go up or down before proceeding to use the ramp. Perhaps this highlights the need to re-imagine the designs of footbridges. The current designs are not inclusive or equitable for all users. But whether footbridges are required in the first place is another matter.

On intersection treatments for bicycles
With the increasing popularity of bicycles as a mode of transport particularly for commuting (e.g., bike-to-work, bike-to-school), we should be redesigning our intersections to include elements essential for the safety of all users, whether on motorized or non-motorized modes. Here is a short but very informative article on how a simple intersection treatment can significantly improve safety for everyone especially cyclists and pedestrians:
Grief, N. (December 2, 2022) “How Green Paint Can Save Cyclists’ Lives,” Bicycling.com, https://www.bicycling.com/news/a42124210/bike-boxes-intersections/ [Last accessed: 12/3/2022]
To quote from the article:
“A bike box, on the other hand, seems to be the ideal middle ground and the option of the three that these researchers recommend. Cyclists feel more comfortable when compared to the free-for-all of a mixing zone because they have a designated area to be and they’re out ahead of vehicles, but according to the eye movement analysis, they remain alert and watchful for vehicles.”
Here are a couple of drawings showing bike boxes at intersections from the recent Bike Lanes Master Plan for Metro Manila, Metro Cebu and Metro Davao that was developed by DOTr with assistance from the UNDP:
Bike boxes on a typical three-leg intersection (DOTr and UNDP, 2022)
Bike boxes on a typical four-leg intersection (DOTr and UNDP, 2022)
The preceding drawings adhere to the DPWH design guidelines that mainly follow AASHTO Guidelines. Of course, there are other design references such as NACTO and the manuals of other countries (e.g., Netherlands, Australia, Singapore, etc.) were the best practice designs can be adopted for local applications.

Bike lanes at Bonifacio Global City
After settling down at our new ‘tambayan’ at BGC, I decided to take my regular morning walk around the area to familiarize myself with the environs and to establish a route that I and the wife would likely be taking for our constitutionals whenever we are staying at BGC. I took the following photos of the bike lanes along 38th Street where most of the locators are international schools.
During Saturday and Sunday mornings, the bollards are moved to the sidewalk as many cyclists use 38th Street for laps. I wonder if the bike lanes will be retained once the schools resume face-to-face classes. That would mean a tremendous number of private vehicles generated by the international schools and colleges here. My opinion is that the bike lanes need to be retained as it is a step in the right direction for transport and encourages people to cycle or take PMDs to work and perhaps to school. These and others like it in Metro Manila and around the country need to be sustained and further developed to be attractive and viable to many seeking another option for mobility and their regular commutes.

On bicycle economics in the Philippines
I am sharing this link to a newly minted reference that should be useful to policy or decision-makers (yes, that includes politicians) in justifying bicycle facilities including bike lanes around the country.
https://www.freiheit.org/philippines/bikenomics-assessing-value-cycling-philippines
There’s been a dearth in local references and this should suffice for now pending more in-depth studies on the benefits of cycling and related-facilities and programs in the Philippines. Note that while the reference mentions certain calculations and unit costs, it would be better to have the actual numbers from the various LGUs that have constructed bike lanes and facilities, and implementing bike programs and projects. Quezon City and Mandaue City, for example, should have the numbers that can serve as initial data for compiling and eventual publication of unit costs per type or design of bike lanes or bikeways. LGUs and national government should gather, process and make use of such data in aid of bike facilities and infrastructure development that will attract people away from private motor vehicle use while reinforcing both active and public transport mode shares.

On the other benefits of cycling – pavements
Here is a very interesting article that tackles a not so obvious benefit of switching to cycling:
Dion, R. (July 12, 2021) “Biking’s Billion-Dollar Value, Right Under Our Wheels,” Planetizen, https://www.planetizen.com/features/113986-bikings-billion-dollar-value-right-under-our-wheels?utm_source=newswire&utm_medium=email&utm_campaign=news-07262021&mc_cid=51555c9a39&mc_eid=9ccfe464b1 [Last accessed: 8/4/2021]
To quote: “A strategic switch to biking would dramatically reduce the depth of roads, saving untold billions over the next generation.”
This is relevant from the perspective of highway engineering particularly concerning pavement design, construction and maintenance. It is intriguing, too, since pavement design (and consequently pavement thickness) is not necessarily correspondent to light vehicle traffic volumes. In the Philippines, for example, only heavy vehicles are considered for the pavement load estimation. It is assumed that light vehicle traffic, which compose most of the traffic along roads contribute mainly to pavement weathering rather than structural aspects.

On bicycles slowing down cars
There is a perception that cyclists tend to slow down other vehicles, mainly motorized, along roads. Again, such can be the experience of some that have been generalized and accepted as fact in most cases. However, if we look closely at the evidence, the perception may not be true for most cases after all. This article comes out of Portland State University:
Schaefer, J., Figliozzi, M. and Unnikrishnan, A. (2020) “Do bicycles slow down cars on low speed, low traffic roads? Latest research says ‘no’,” EurekAlert!, https://eurekalert.org/pub_releases/2020-07/psu-dbs072320.php [Last accessed: 8/1/2020]
Check out the wealth of information through the links found throughout the article that includes references to published material in reputable journals. EurekAlert! is from the American Association for the Advancement of Science (AAAS).

Caught (up) in traffic
