On the reduced traffic due to the energy crisis
The past weeks have seen traffic reduced along my usual routes for my commute between my home and workplace. This could be attributed to the energy crisis as, apparently, many have chosen to plan their trips and use other options other than private/personal transportation for their travels. The reduction in traffic is probably due to reduced numbers of private cars and motorcycles as people cut down on unnecessary trips. Of course, most schools are off at this time of the year so that means a significant number of trips are off the roads (and rails in the case of Metro Manila).
My travel time is only about 60 to 70% of the usual during peak hours. And about half during off-peak. That is a significant reduction in travel time and perhaps translates to not just reduced fuel consumption in general but also reduced emissions as well. On weekends, I also observed that there are less motorcycle traffic to and from Antipolo where I reside. I am referring to the groups who usually have their recreational rides during weekends. Did bicycle traffic increase? My observation is that there seems to be an increase for the weekdays but it’s about the same on weekends. Bicycles, after all, are not affected by the fuel price hikes. Perhaps people who can bike opt for the mode instead of their motorized vehicles? The only way to determine if indeed there were significant mode shift is to do surveys. But for now, careful observation not of traffic but travel times will suffice as proof of the easing of traffic due to the crisis.

E-vehicles? Sana all!
The current energy crisis was brought about by the US waging a war against Iran, resulting in the closure of the Strait of Hormuz. Since much of the Philippines fuels come from the region and given the country’s dependence on oil from the Middle East, the limited supply led to steep increases in the price of fuels. One reaction to this was people suddenly purchasing hybrid and electric vehicles to replace their fossil fuel-powered vehicles, or as another vehicle in their garages. Sales of hybrid and electric vehicles surged the past weeks. However, this reaction among private vehicle owners only showed the disparity among people who struggled to find ways to commute mainly via public transportation or their only vehicle and those who can afford to own several vehicles.
One colleague joked that if you want to see what electric and hybrid models are available across various vehicle types (e.g., cars, SUVs, vans, etc.), you only need to travel along Katipunan. There you will see all types of hybrid and electric vehicles including the most popular ones to the more recent models. Many are SUVs and then there are the luxury brands somewhat being paraded by those who opt for them instead of the Chinese brands. Should we be happy for them? Maybe. Should we be envious? Maybe not. The standard defense for these purchases usually runs along the lines of the owners spending their hard-earned money. So let’s leave it at that. Let those who can afford to buy new vehicles do so if that’s their way of coping with the crisis. Meanwhile, we should lobby for better public transportation services and active transport facilities so the majority of people who need to travel can do so without having to buy their own vehicles.

Some thoughts on PUV modernization in the context of the energy crisis
One can help but recall a lot of things past during slow days like those on Holy Week. I was able to write about memories of spending the Holy Week in Iloilo during my younger days. I myself spent most of my Holy Weeks there until after College. My annual “recharging” was only interrupted when I was abroad for three years in the late 1990s. I don’t recall now the last time I was there for Holy Week but perhaps it was after I got married more than 20 years ago. The recollection this week was not only about the sentimental stuff of my childhood and teen days. I couldn’t help but recall some of the work we did many years ago on trying to modernize public utility vehicles, particularly jeepneys.
I was involved in some DOTC (what the DOTr was then) programs and projects about 15 years ago where we sought to replace the old conventional jeepney engines with newer models. This was to reduce emissions and improve fuel efficiency. Electric jeepneys then were still crude in terms of motors and batteries though the body designs were patterned after the conventional jeepneys. They were not as viable as the current models available now. There were also few designs of modern jitneys or minibuses at the time. And jeepney operators and drivers groups indicated their receptiveness to engine replacement. So it was logical to consider engine replacement at the time. Unfortunately, some groups strongly opposed this leaving nothing accomplished from the time.
Fast forward to the present and now, it seems it was correct to at least propose engine replacement at the time. Jeepney engines could have been more fuel efficient aside from having less emissions. Of course, it is now moot and academic and the current crisis might just result in jeepney operators and drivers giving up on their pasada. There is the opinion that jeepneys have been coddled and romanticized for quite some time now (since the 1970s?). It is perhaps time to phase out old vehicles in favor of modern ones. A message to progressive groups though: let’s learn from the lessons of this energy crisis and help with pushing for modernization of road-based public transport. If its the prices of the new models that pose as barriers then lets find ways for more acceptable and affordable financing schemes. Should there be a variant of service contracting by national and/or local government? Find solutions rather than find ways to inhibit or prevent modernization. Throwing obstacles has cost commuters a lot in terms of time and money. Commuters deserve a more modern and efficient transportation system.

Some thoughts and reflections on transport and the Middle East crisis
Much has been said and written about the ongoing crisis brought about by the US and Israel attacking Iran and the latter retaliating. The prices of fuel have risen rapidly over the past weeks. Consequently, the prices of commodities have also risen. The Philippines is still very much dependent of fossil fuels for transportation with most travel using road-based transport. Even public transportation relies heavily on fossil fuels as buses and jeepneys are mostly using diesel engines. Even paratransit such as trikes and motorcycle taxis use gasoline.
While the energy mix in the country has become more diversified with renewables now having a substantial share, majority of power is produces using coal and natural gas. And so e-powered vehicles are also ultimately dependent on these fuels. Could we have had better transport that could have made our cities more resilient in light of the conflict in the Middle East? Probably, and if we followed and implemented the plans for mass transit systems that were laid out decades ago. Of course, this is already moot and academic given the current situation. The counterfactuals though point to better commuting conditions if projects have not been delayed or shelved.
A colleague and I were just discussing about how MRT 7 could have contributed to the reduction of car use along the Commonwealth Avenue corridor if it was completed according to the original schedule. That was 2019. Even with delays including the impact of the pandemic, it could have been completed a few years ago. If it was operational in 2023, commuters could have already shifted to rail from both private and public road-based transport modes. There was also actually a proposal for a Bus Rapid Transit (BRT) line along Commonwealth about 2 decades ago. That could have been constructed and operational ahead of Line 7 and could have already disrupted commuting preferences along the corridor if it were operated as a true BRT.
There’s just a lot of opportunities already missed that could have alleviated the fuel crisis we have now. Maybe we are really heading towards a bigger crisis when all these price increases lead to a more sweeping increase in the prices of commodities? We hope it doesn’t come to that but we seem to be helpless in this situation where we are caught unprepared for a war we are have nothing to do with.

On using Google Maps to determine the best route from the pollution perspective
I saw this article on digital maps (i.e., Google Maps) being used to determine the best route for traveling between an origin and destination on land. It is interesting because what we usually use as basis for selecting our routes (assuming we can do so since people taking public transport basically have fewer options due to PUVs having mostly fixed routes) are travel time, travel distance and travel cost. Here is the article discussing the addition of fuel efficiency and emissions to the criteria:
Calma, J. (July 25, 2023) “People are using Google Maps to cut down tailpipe pollution,” The Verge, https://www.theverge.com/2023/7/24/23805652/google-maps-fuel-efficient-routes-transportation-emissions [Last accessed: 7/29/2023]
To quote from the article:
“According to Google’s own analysis, many drivers are taking the path of least pollution in their cars. To calculate the tailpipe emissions that prevented, the company compared how much fuel Maps users likely consumed on the routes they drove to how much fuel they would have burned through had they taken the fastest route without its eco-friendly routing tool. The savings amounted to 1.2 million metric tons of avoided CO2 emissions between October 2021, when Google launched the tool, and December 2022.”
While this seems to be a first foray into the including of eco-friendly items in route choice, these items are already and actually included in many travel planners including those used by people selecting which flights to take. We probably just didn’t notice them before or the information were not explicitly stated or posted. Would this really affect or influence the way we travel like how it is reported in the article? Or do we continue to go with the usual and familiar routes?

On electric vehicles and informal transport
I’ve been involved in studies on electric vehicles and their applications in the past. I continue to take part in studies about informal transport including continuing research on motorcycle taxis or “habal-habal” as they are called in the Philippines. The combination of the two is an interesting research area and there are many topics that can be developed as we determine the most appropriate applications for electric vehicles. Here is an interesting article on electrifying informal transport that sets the context for research:
Ribet, L. (August 30, 2022) “The role of data in electrifying informal transport,” Slocat partnership, https://slocat.net/the-role-of-data-in-electrifying-informal-transport/ [Last accessed: 9/9/2022]
To quote from the article:
“However, electric two-and-three wheeler startups, informal transport retrofitting pilots and e-bus initiatives cannot be the only answer to the mobility challenges facing developing cities. Phasing out oil-reliant public transportation is needed and investing in electric mobility solutions may well improve the overall picture quite substantially, but there is a far larger challenge that is omitted from these ambitions: addressing the complex operations of informal transport systems that characterise lower-income countries’ urban mobility. Electrifying minibus taxis is not synonymous with more reliable, affordable and convenient public transport, and we need to prioritise the understanding and improvement of overall informal transport systems data first.”

How can e-scooters become a safer way to travel?
I’ve shared some articles and opinions about electric scooters. Here is another one that delves into the safety about these vehicles that have become quite popular in the US. Here in the Philippines, they still seem to be in infancy in terms of popularity and to some, are seen as more a novelty and touristy rather than a mode of transport for the typical work trips.
Donahue, B (June 11, 2022) “How to Make Electric Scooters Become a Safer Way to Travel,” Bloomberg, https://www.bloomberg.com/news/features/2022-06-11/how-to-make-electric-scooters-safer [Last accessed: 6/18/2022]
To quote from the article:
“Dediu believes that in time micromobility will attain critical mass, as other modes of transit have already done, and that infrastructure will come as the user base grows. “We didn’t build airports and then have airplanes show up,” he’s said. “I’m confident, given the history, that we’ll see things like more safe roadways for micromobility vehicles.” “
Scoot-to-work at BGC, Taguig, Metro Manila
It is not really about the vehicle but the environment in which it is being used. One can say a lot about walking, for example, being dangerous but without touching on the why and the how its become a dangerous or risky mode of travel. It’s the lack of infrastructure or facilities as well as the car-oriented environment (that includes archaic laws and other regulations) that make active mobility and micro mobility modes dangerous or risky. If we can address these basic issues, then perhaps we can entice more people to use these modes more often and for the most trips we make everyday.
And don’t forget that these modes are the most fuel efficient! Saves you from the every increasing prices of fuel!

Paper: Estimation of Transportation Energy Demand of the Philippines Using A Bottom-up Approach
Our paper from a conference last year is finally published in an open access journal. The paper is on the “Estimation of Transportation Energy Demand of the Philippines Using A Bottom-up Approach.” Here is the abstract of the paper:
“In the years 2000–2016, the sector with the largest share of total final energy consumption in the Philippines is transportation with an average share of 34.2%. The study aims to estimate the baseline transportation energy demand of road, maritime, air and rail transportation modes in 2016 using a bottom-up approach. Through a bottom-up approach and utilizing available transportation activity and fuel economy/energy efficiency data from secondary sources coupled with primary road transportation activity and fuel economy and railway operations survey data, the baseline transportation energy demand of the Philippines is estimated to be 12,956.1 ktoe in 2016. A comprehensive estimation of transportation energy demand of the country using bottom-up methodologies with more detailed transportation activity and vehicle fleet of the different transportation modes is implemented. Finally, the collection and keeping of certain data that are critical in the estimation of the transportation energy demand are recommended.”
Here is the link to the paper, which is published in the Asian Transport Studies, Vol. 8, 2022: https://authors.elsevier.com/sd/article/S2185-5560(22)00004-9

Article on evaluating transport equity
Here is another quick share of an article on transportation equity:
Litman, T. (February 2, 2022) “Evaluating Transportation Equity: ITE Quickbite,” Planetizen, https://www.planetizen.com/news/2022/02/116058-evaluating-transportation-equity-ite-quickbite [Last accessed: 2/4/2022]
Transportation equity is a very relevant, very timely topic as people in the Philippines are just beginning to understand and weigh the advantages of having more efficient transport in the forms of active and public transport over private vehicles.

2014 Professorial Chair lectures on transport topics
The 2014 Professorial Chair Colloquium of UP Diliman’s College of Engineering was held from yesterday until today. Most of the lectures concerning transport were presented today. Here are some of the highlights of the lectures delivered this morning:
Dr. Ric Sigua, Director of the Institute of Civil Engineering, making a point about the economics of Bus Rapid Transit (BRT).
Dr. Sean Palmiano, Director of the National Center for Transportation Studies, explaining the finer points of traffic impact assessment for high density residential developments.
Prof. Happy Denoga of the Department of Mechanical Engineering explaining on the advantages of hybrid systems for vehicles.
Dr. Karl Vergel of the Institute of Civil Engineering talking about the on-road tests for jeepneys using B5 or 5% CME-blended fuels in a project commissioned by the Philippine Coconut Authority.
Comparison of jeepney mileage using 2% and 5% blended fuels.
Dr. Edwin Quiros of the Department of Mechanical Engineering’s Vehicle Research and Testing Laboratory (VRTL) discussing the dynamometer tests conducted for jeepneys using B5 fuel.
There were other presentations but unfortunately, I wasn’t able to attend these as lectures were spread among various venues at the college. That’s often the hang-up of having parallel sessions during these colloquiums. Nevertheless, it is nice to know that transport remains a popular subject for these lectures.

Caught (up) in traffic
