Future jeepney: BEEP
The National Center for Transportation Studies (NCTS) of the University of the Philippines Diliman (UPD) is part of the Phase II of a research comparing the performances of customized local road vehicles (CLRV) for use in public transport. This project is being conducted together with the Vehicle Research and Testing Laboratory (VRTL) of UPD’s Department of Mechanical Engineering (DME), Electrical and Electronics Engineering Institute (EEEI) and the National Engineering Center (NEC) with funding from the Department of Energy (DOE). Phase II considers a longer route for the comparison of vehicles. In the previous Phase I, the route was UP Diliman-North EDSA while in this phase, the route will be Lagro-Cubao, which is significantly longer in distance compared to the previous study route.
Here are the specs for the BEEP, which features some significant design changes from the earlier versions of the e-jeepney:
It is worth noting the following for the BEEP:
1. The door is already located on the side of the vehicle instead of at the back.
2. The motor is rated at 30kW, a significant upgrade from the 15- and 20kW motors in previous e-jeepneys.
3. The seating capacity is for 20 passengers (excluding the driver) by about 2 to 4 people from previous e-jeepney models.
These are the most obvious changes in the BEEP and would be factors that could affect its performance and acceptability. Most jeepneys these days are “siyaman” meaning they seat 9 passengers on each of the bench seats plus 2 on the front seat for a total of 20 passengers. Also, jeepneys should be able to negotiate steeper slopes that have been among the problems for e-jeepneys. Not mentioned are the specs of the batteries and the charging time although the range claimed for a full charge is 85 km. This study will hopefully validate these claims and show us if the BEEP will be up to the challenge of replacing the conventional jeepneys on long routes.

Updates on the DOST’s AGT project
It’s been a while since I’ve written about the Automated Guideway Transit (AGT) system being developed by the Department of Science and Technology (DOST) through its Metals Industry Research and Development Center (MIRDC). Instead of “reinventing the wheel” in writing an update article, I will just point my readers to the “official” item from the DOST’s Philippine Council for Industry, Energy and Emerging Technology Research and Development (PCIEERD). The following link provides a very detailed update on the AGT project including the pre-feasibility studies being undertaken for where the system might be deployed:
Filipino-made Automated Guide-way Transit System (AGT) Eyes to Curb Air Pollution and Traffic
Unfortunately, there is no information on the locally-developed AGT undergoing rigorous testing towards certifying its being safe for public use (i.e., as public transport). There are few testing facilities for such vehicles including those in the US, Japan, Korea and Europe. The DOST needs to collaborate or engage a legitimate testing center that will objectively conduct the strict tests required to ensure the AGT is technically sound and therefore safe for use. Leap-frogging for these technologies does not mean one also can bypass certain requirements for standards and the DOST owes it to the people who will ride this transit system to have it certified – validating its motto “proudly Philippine-made.”

Research agenda and topic selection
A friend asked me how topics for research are selected by our students. Were these assigned to them or were they able to select from a list of topics provided to them? The answer is actually “either” or in some cases, “both.” We provide a list of topics to our students and they get to select the topics. Some topics are quite popular so we ask students to state their first and second choices, and then ask faculty advisers to discuss the topics with the students to determine the specifics as well as whether groups can be composed to tackle certain topics.
The Institute of Civil Engineering’s six groups (Construction Engineering & Management, Environmental, Geotechnical, Structural, Transportation, and Water Resources) all have their own research agenda, which are typically classified for the short, medium and long terms, as well as for the main and sub-topics each group has identified. The agenda are regularly updated, at least once a year prior to the start of the academic year.
The current research agenda of the Transportation Engineering Group (TEG) includes topics under the following general headings:
- Traffic Engineering and Management/ Traffic Flow
- Public Transport Planning and Travel Demand Management
- Road Safety and Maintenance
- Transport, Environment and Energy
- Rail, Aviation and Maritime Transport
- Transportation and Technology
- Transport Logistics
The specific research topics under each category change according to several factors including the current researches being undertaken by faculty members. There is also a strong influence from the Engineering Research and Development for Technology (ERDT) program supported by the Department of Science and Technology (DOST). The TEG is also strongly associated with the National Center for Transportation Studies (NCTS) and researches have been supported by NCTS projects. In recent years, there has been a lot of topics dealing with issues at and around the University of the Philippines Diliman campus including studies on public transport (e.g., UP – Katipunan jeepneys, UP – North EDSA jeepneys, etc.) and traffic along major roads (e.g., Commonwealth Avenue, Katipunan Avenue, etc.). These studies are part of initiatives to help address “local” issues. The logic here is that if we cannot solve such “local” problems then we have no business trying to solve problems elsewhere. This is also part of the thinking of UP as a microcosm of the Philippines.

Some questions on a gloomy Saturday morning
On gloomy Saturdays like today, I often tend to sort of contemplate on some questions coming from events and articles the past few days. I don’t really want to answer these questions right now and immediately but would rather let these and the follow-ups play around in my mind. I would rather not do some shout outs on social media about these questions as some friends tend to be sensitive and I don’t really want to make a lot of effort carefully framing posts on FB just so they won’t appear to be offending certain persons who might be over-zealous about their advocacies or who would be so defensive of their organizations. Here are some questions running around in my brain right now:
1. Does DENR have the mandate to require sidewalks and bikeways along all roads? Design and implementation-wise, isn’t this supposed to be under the DPWH (for national roads) and the LGUs (for local roads)? Is this more a policy statement? But then shouldn’t this come from DOTC?
2. Is going out of your way really the way to get noticed and be awarded? Are there no points for people doing a great job at what they are supposed to be doing?
3. Shouldn’t an agency first check if they are doing what they are supposed to do and the outcomes reflect their objectives? Are emissions testings and monitoring successful or do we still have a lot of smoke-belchers on our roads? If they already have their hands full with their tasks according to their mandate, shouldn’t they first mind their business before even encroaching into another agency’s tasks?
4. Does media have to give so much airtime to a driver of a luxury vehicle who assaulted a traffic enforcer?
5. Why does it seem to be so much fuzz about Uber? Is it just on social media? Do most other commuters give a damn about it when they really can’t afford availing such services?
6. Are government engineers bereft of an appreciation for the arts, culture and heritage? Are they too mechanical or dumb to understand what planning and design really is all about?

On doing research for your undergraduate course requirements
It’s that time of year again when we are swamped with requests for interviews from students taking undergraduate courses. These undergraduate courses include those on Science, Technology and Society, English, Communications, Architecture, Geography, Business, and Economics. These requests are not limited to students from our university but also come from students in other schools as well. While we are happy to oblige, granting interviews face-to-face or through correspondence (through email, of course), we are becoming wary about students not doing their part first before requesting an interview. In many cases, they just fire off a list of questions in the first email, probably hoping the addressee would be kind enough to answer all these questions in a comprehensive manner. That way, perhaps the student will be able to save on time and effort in doing his/her report. That’s right, let the expert answer all the questions and tell me what references I should list down in my report. If the student can’t understand what the expert wrote in reply or if the student thinks its not enough, then the latter could just send a follow-up with additional questions or request another interview.
Is this the right way to do research? I do not agree with this and perhaps the faculty handling their respective courses these students are enrolled under should take care in how they frame their requirements. It is as if they are passing on their responsibilities to other faculty members, experts in their particular fields, who would have to contend with requests for interviews or outright questions in their emails. That’s probably understandable for general education courses like English and STS, but not acceptable for undergraduate research projects that are supposed to be “capping” courses in their programs.
How do I address such inquiries in my mailbox? I do respond immediately and in fairness to the students whom I assume are somewhat misguided in his/her research work; particularly on how to conduct research. My usual reply is that I cannot accommodate the request due to my schedule followed by a counter-request for the student to send me his/her questions first (if he/she hasn’t done so in the first email). If I already have an idea of the students’ topics, then I would suggest some reading material or references first, and hopefully that can help the students frame their questions. That way, I can gauge if the students are really serious about their research or are just going through the motions. It’s difficult for me to be serious or passionate with my replies if the person on the other side of the proverbial table is not at all interested in the topic and treats the exercise as just another requirement for him/her to get a good grade.
Doing his/her part before even contacting experts mean the student needs to do some literature review. That can be in the form of research online and not the kind where the student will just mention a few articles (often opinion pieces) that they read on Rappler, Yahoo or other online sources. There’s a wealth of more scholarly and objective information now available on the net and UP students have access to journals, books and other references through the university’s libraries. These are privileges that they have already paid for as part of their tuition so why let these resources go to waste? I believe students can do a good job in their research projects if they are given proper guidance by their advisers or instructors, who should be the “first line of defense” against mediocrity in their studies at this level. Getting rarer these days are students who come in prepared and are really passionate about the topics they are studying.

The numbers that matter – some thoughts on data
Too often we are bombarded with statistics, numbers that are supposed to describe the state of things. This is especially true in transportation and traffic where there seems to be a lot of information or data circulating about all kinds of stuff usually including numbers of vehicles, speeds, quantities of people and goods transported, and so on.
There is a tremendous amount of data collected by many government agencies. These include traffic counts by the DPWH, port and airport statistics by the PPA and CAAP, and socio-economic data from all over the country by the NSO. There is also wealth of information that can be derived from various project reports whether these be infrastructure master plans or evaluations of policies and programs related to transport and traffic. Local governments that require transport impact studies for developments within their jurisdictions are supposed to compile the data contained in these reports, which include traffic counts and projections at roads and intersections, transport facilities inventories, and travel time and delay data among others essential for impact analysis.
Origin-Destination (OD) data are important for planning transport from the national to local levels. Inter-regional, inter-provincial or inter-city OD data for people and freight are essential for planning infrastructure that would be able to adequately and efficiently handle the traffic between regions, provinces and cities/municipalities. As it is impractical (i.e., costly) to determine the exact numbers of traffic for all modes on a very frequent basis, sampling is very important and the determination of sample size as well as the sectors and areas to be sampled are essential aspects of any study. The current MMUTIS Update and Capacity Enhancement Project (MUCEP) that is the long-delayed follow-up to the Metro Manila Urban Transportation Integration Study (MMUTIS), for example, required household information surveys (HIS) for an area that is now referred to as Mega Manila, which is basically comprised of Metro Manila, Region 3 and Region 4A. Such a large study area necessitates careful sampling in order for assumptions regarding the data aggregation and disaggregation to hold.
Often, for many studies concerning cities and regions, person trip and freight volume data are more valuable than vehicle trip data. Though vehicle volumes are important, the number of people traveling or the amount of goods being transported are a better basis for planning transport. This is especially true for passengers as it is desirable to have the numbers as the basis for determining the frequencies (how often and with what schedule) and capacities (vehicle size/passenger capacity), which need to be balanced or optimized according to the demand. This demand is variable throughout the year and the day and will definitely have implications on revenues. There are desirable schedules for passengers as well as for goods. Moreover, it is important to determine also the trip distances that would allow for the estimation of the number of trips in terms of passenger-km and ton-km units. Such information are useful for travel demand modeling and forecasting including the evaluation of suitable transport modes and service characteristics for passengers and freight.

- Air quality assessment at the Centennial Dormitory along C.P. Garcia Avenue
- Estimating bus passenger demand between UP Diliman and UP Los Banos
- Mode choice modelling of new transport systems
- On-road energy efficiency of alternative fuel vehicles
Note that several topics in the list are focused on issues concerning the UP Diliman campus. These are a continuation of studies geared at providing solutions to transport or traffic problems at UP’s flagship campus sprawled over an area of 493 hectares. The above are working titles at best as students taking up the topics are supposed to develop their research proposals (complete with literature review, methodology and budget) this semester and then implement these in the next semester. Since UP has already adjusted its academic calendar, research implementation will be undertaken from January to May 2015.

Interesting articles on traffic congestion
Here are a few good reads on traffic congestion and its measurement or quantification:
- How Not To Measure Traffic Congestion—Hold the Hyperbole, Please! which appears on Planetizen today, October 15, 2014.
- Rethinking the economics of traffic congestion which appeared on June 1, 2012.
Reading these articles will probably make you think that traffic is good or that congestion is good. While congestion is indeed indicative of economic vibrance as movement of people and goods are a good measure for economic activity, excessive congestion results in many other problems that need to be addressed and which can also be quantified in economic terms. Note, too, that one author mentions “peak traffic” that is now becoming common in developed countries as motorization has plateaued and transport systems have become developed to provide people and goods with a variety of modes to choose from including walking and cycling. In our case, traffic has not yet “peaked” in the sense that motorization continues for many of our cities including Metro Manila. There is also a lag in the provision of transport infrastructure including mass transit systems that should have been constructed decades if not years ago. Perhaps we need to be clear about the context by which congestion costs are estimated and presented.
The somewhat dramatic presentations like the manner shown in the first article above reminds us of similar estimates of congestion costs in the Philippines, particularly for Metro Manila. The latest of these come from a JICA project that had as an objective the drafting of a roadmap for transport in the expanded region that is dubbed as Mega Manila (Region 3, National Capital Region and Region 4A). The end product has been billed as a “Dream Plan for Mega Manila” and draws on congestion cost estimates that would definitely be regarded as exaggerated if seen in the context of the two articles we mentioned above. Perhaps it is the important message (i.e., we need to build transport infrastructure) of such exaggerated presentations that we should focus on an not really the specific numbers being quoted by news organizations and circulated in social media.
We have to caution the reader that congestion is here to stay and cannot be totally eliminated, especially with economically vibrant or growing cities. What we probably would like to address, however, is excessive congestion. Yes, there is such a thing as excessive congestion. I would like to describe this as something that is “unreasonable” along the lines of say instead of your regular 1 hour commute, it took you 2 hours or more. For some, this can be due to horrendous traffic jams due to flooded streets. Or perhaps someone who takes public transport waiting for hours just to get a ride. And so people are forced to cope and in a way, their minds have been conditioned to tolerate (accept?) the levels of congestion they experience on a daily basis. Congestion is good but it does not have to be hellish.

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
