Research topics for transportation engineering and planning for 2016-2017?

I observed from my site’s statistics that there have been a lot of interest on research topics in transportation engineering and planning. I regularly post on the undergraduate research topics our students have engaged in. At this point in the first semester of the current 2016-2017 academic year, topics have not yet been assigned and we have only learned how many students have been assigned to our research group. As such, we are still in the process of determining who takes on which topic. Following are topics we have identified in addition to those that had no takers the previous semesters:

Traffic engineering

  1. Anatomy of congestion along EDSA
  2. Anatomy of congestion along C-5
  3. Segregated lane for motorcycles
  4. Impacts of the MMDA’s truck lane policy along C-5
  5. Congestion study in the vicinity of UP Town Center
  6. Assessment of through traffic for the UP Diliman campus

Public transportation

  1. Connectivity study for UP AGT and MRT 7
  2. Feasibility of bus services beyond Masinag junction
  3. Characterization of Internal Public Transportation Operation in UP Diliman and Viability of Introduction of Electric Vehicles
  4. Modelling the Public Transport System of UP Diliman Campus Using CUBE Travel Demand Software
  5. Estimation of Passenger Demand for New Transit System for UP Diliman Using Discrete Choice Model
  6. Characteristics of motorcycle taxis in the Philippines [Habal-habal, skylab, etc.]

Road safety

  1. Severity of injuries of motorcycle riders (helmet and non-helmet users)

Pedestrian & non-motorised transport

  1. A study on walkability along Ortigas Avenue
  2. A study on the characteristics of bike share users in the UP Diliman campus

Transport & Environment

  1. Assessment of Roadside Air Quality along C.P. Garcia Avenue in the Vicinity of UP-ICE Compound

Other topics

  1. Study on the mobility of PWDs in Metro Manila
  2. Assessment of ridesharing in the context of sustainable transport

I’m sure there are other topics but I’m not aware of the specifics at present. Also, we welcome the ideas of our students should they already have topics in mind as long as these preferably fall under the research agenda of our Institute. The topics listed above may appear to be specific but these are still basically very general and can be refined after the students establish their scope and limitations. They can only do that once they have undertaken a decent enough literature review for them also to have a more firm appreciation of their chosen topics. I will post again on this later this year when students would have already put in substantial work on their research proposals (i.e., the objective for this semester).

Evidence from Montreal: Building bike lanes to reduce car use

I just wanted to share this article showing evidence of car use reduction (and therefore, car traffic along roads) with the provision of bicycle lanes.

Building Bike Lanes Really Does Get More People Out of Their Cars

The article though cautions readers against generalising or assuming great improvements. Some figures mentioned in the article including the following (I took the liberty of copying and pasting):

  • “A 10% increase in bike accessibility resulted in only a 3.7% increase in ridership.”
  • “…cycling infrastructure also reduced greenhouse gas emissions from cars by 1.7%, a reduction equivalent to converting transit buses to hybrids and electrifying commuter trains.”

These numbers are for the case of Montreal, Canada. Not mentioned are the number of cyclists, vehicle traffic volumes and other pertinent data that are useful in analysis. The article correctly points out the importance of using science (e.g., sound analysis based on good data) in order to convince governments to put up bicycle infrastructure. I would even add that this approach should also be applicable to pedestrian facilities.

Bicycle traffic in comparison with motorised vehicle traffic – a case in Iloilo City

I believe that there is a need to have numbers to guide planners and engineers in designing suitable bicycle facilities. It is not enough to claim there is demand since an important requirement for facilities to be provided (i.e., funded and constructed) are numbers for the facilities’ justification. You don’t build mass transit systems, for example, without a valid estimate of ridership. For one, the ridership allows for the determination of revenues. Roads cannot be built without at least a number like the population of communities that will be given accessibility via that road.

Not too long ago, we were able to obtain traffic counts for the Benign S. Aquino Avenue that is also knows as the Iloilo City Diversion Road. The road includes an exclusive bikeway constructed along its airport-bound side that is supposed to benefit cyclists and encourage more people to use bicycles for commuting within the city and between the city and towns along the national highway. The following figures show the AM and PM peak hour traffic at the intersection of the diversion road and Jalandoni Street across from SM City Iloilo. Another figure shows 16-hour traffic at the same location.

Traffic Volume Count-Diversion Road-Jalandoni-PMFig. 1 – AM peak hour traffic along the Iloilo City Diversion Road including bicycle traffic along the exclusive bikeways constructed along the airport-bound side of the highway.

Traffic Volume Count-Diversion Road-Jalandoni-AMPM peak hour traffic along the Iloilo City Diversion Road including bicycle traffic along the exclusive bikeways constructed along the airport-bound side of the highway.

Traffic Volume Count-Diversion Road-Jalandoni-16H16-hour traffic along the Iloilo City Diversion Road including bicycle traffic along the exclusive bikeways constructed along the airport-bound side of the highway.

The numbers clearly show the current low volume of bicycles along the bikeways in comparison to motor vehicle traffic. Since bicycles are also presumed to carry only 1 passenger per vehicle, then the volume also translates into an even lower share in terms of mode of choice by travellers/commuters. For comparison, jeepneys will likely carry an average of 14 passengers while cars may have an occupancy of 1.5 passengers per vehicle. Perhaps a more direct comparison can be made with motorcycles, which are two-wheeled vehicles like bicycles. Only, motorcycles may typically carry 2 passengers.

I am aware that at least one NGO is employing crowd-sourcing in order to obtain bicycle traffic counts along major corridors. Neither the MMDA nor the DPWH have bicycle counts with both agencies’ traffic counts only covering motorized vehicles. Few, if any, local government units would have their own bicycle traffic counts (Perhaps Marikina has data of bicycle traffic in their city that is well known for having the country’s first and most comprehensive bikeways network?). As such, there is generally a dearth of useful data for planning bikeways. One option that advocates for the “if you build it, they will come” approach is not something that is applicable to many cases especially those that do not yet require exclusive bikeways. The folly is to allocate funding for facilities that will not be utilised by their proposed users.

Metro Manila Skybridge: for cars or bicycles?

I was browsing over a not so old, pre-election issue of Top Gear magazine and came upon an article that featured then Senatorial candidate and already former Metro Manila Development Authority (MMDA) Chair Francis Tolentino. The article stated the former MMDA Chair’s frustration that his pet project didn’t get approval from NEDA. The Skybridge he was proposing was basically an elevated road that was to be built on top of Metro Manila rivers. This is in part to save on RROW costs and supposedly to also reduce traffic impacts of construction (note the traffic congestion due to the Skyway Stage 3 construction).

I think that such a Skybridge could have had a positive impact on traffic congestion but for a short time only. The sheer number of vehicles in Metro Manila will only lead to congestion elsewhere being transferred here and, under equilibrium conditions that will eventually be attained as some time in the near future, will ultimately be congested. The concept of tollways is for people to pay for the use of a facility in return for high level of service (read: faster travel). Skyways and other elevated highways cost a lot and the NEDA probably didn’t see a free use elevated structure like the Skybridge having much in terms of ROI.

There is, however, something that may be worth it in terms of potential congestion reduction as well as enhancement of traffic safety and quality of life – a Skybridge for bicycles and pedestrians. This should encourage people to cycle as travel via such mode will be much safer and could possibly be faster. Friends and acquaintances who are cyclists often post about similar facilities in Europe and how these are able to reduce congestion as people opt to cycle and leave their cars at home during the weekdays.

Biking/cycling in Japan: Can we achieve a similar environment here?

I biked a lot when I stayed in Japan for long periods in four separate periods. These include a 35-day stint in Tokyo, 3 years in Yokohama, and 1.5-month and 3-month stays in Saitama. What I discovered was a safe environment for cycling where motorists generally respect cyclists using the road and sharing road space is a given. I could even use the sidewalk and share it with pedestrians. People seemed to know how to position themselves and respect each others’ right to use facilities, giving way to each other.

Here’s a link to a nice article a friend shared on social media:

Why Tokyo is home to many cyclists but so few bike lanes

My friend also resided in Japan for a few years where I’m sure he also used a bicycle to get around. Hopefully, we can be like the Japanese in terms of how people respect each others’ right to travel as well as one’s choice of transport mode. While it would be nice to have bike lanes (and protected ones at that) this exclusiveness is not an assurance that a similar culture of sharing and respect will develop. Is it a culture thing? Do we need to be encouraged (or forced) to modify behavior? These are but a few questions that need answers and not just by the typical “if you build them, they will come” statement that seems to have become a mantra for hardliners. A more holistic approach is required and it does not come as a surprise that basic transport infrastructure and more efficient services are necessary prerequisite to achieve such a sharing and respectful society.

Helmet or no helmet when biking?

We were at the Department of Science and Technology – Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD) this morning to help defend our proposal for a bike sharing system. UP Bike Share is an initiative coming out of a group of students from various programs in their respective colleges at the University of the Philippines Diliman.

One question that was raised among the technical panel to whom the proposal was presented for evaluation was concerning safety of people participating in the bike share. One panelist asked if cyclists were required to wear helmets. We replied that those participating in the bike share were not required to wear helmets and that despite helmets being available few, if any, borrowed the available helmets. I mentioned that there was an article I came upon before that stated the requiring people to wear helmets discourage biking. It seems a coincidence that as I browsed my Facebook just now, I found a link to that very same article I mentioned in a meeting earlier today:

To encourage biking, cities lose the helmets [by Elisabeth Rosenthal from The New York Times, Sunday Review, September 29, 2012]

The article makes a lot of sense especially the observation that requiring helmets seem to send the message that it is dangerous to bike. People associating danger with biking with helmets tend to opt out of biking. I recall that in Japan before, I didn’t have a problem biking in urban areas and helmets were not required. Of course, drivers of vehicles in are very admirable by the way they drive safely and respecting other road users’ right to the road. Instead of having a campaign to require helmets for bikers perhaps efforts should be focused on how to make our roads safer for all users including bikers and pedestrians.

Towards safer roads: design, respect and education

Fatal crashes involving cyclists have been posted in social media including a recent one involving a mother of two who was run over by a garbage truck that encroached on the on-street/painted bike lane in, of all places, Marikina City. Emphasis on Marikina is made here because it is a city well-known for its comprehensive bikeways network. The network is comprised of segregated and on-street bikeways.

Following are some photos showing examples of good and bad practices pertaining to bikeways design in the Philippines:

IMG03101-20120612-1058

Example of segregated bikeway at the University of the Philippines Diliman campus. Cyclists actually share the carriageway lane allocated from the Academic Oval with pedestrians and joggers. They are not physically protected from motor vehicles that can encroach on the bike lane.

IMG03426-20120707-0902

Example of segregated and protected bikeway along Marcos Highway in Pasig City (similar design for the sections in Marikina, Cainta and Antipolo) – bikeway is on the sidewalk and cyclists essentially share space with pedestrians despite delineations.

2014-02-11 16.58.11

Example of segregated and protected bikeway/walkway along EDSA in Makati City – note that space to be shared by pedestrians and cyclists is very constricted.

2014-02-28 08.31.21

Example of poor design along White Plain Avenue – the MMDA seems to have designated the entire sidewalk space for cyclists.

Three examples from Marikina’s bikeways are shown below:

Granted that the ideal set-up would have segregated or protected bikeways that are designed properly, we take a look at two other very important elements that are not at all as technical as design and planning of bikeways – respect and education.

Education is an important aspect of driving. Many Filipino drivers are poorly educated in terms of traffic rules and regulations, road design as well as local policies pertaining to transport and traffic. As such, there is a tendency for many drivers to disregard rules and drive/ride aggressively and recklessly. This must change and it starts with reforms in the way licenses are issued to all types of drivers including perhaps stricter certification systems for truck drivers and public utility vehicle drivers. Traffic education should also be integrated into the academic curricula of schools starting at a very young age. Road safety parks are one way to promote traffic education for kids.

Respect is partly derived from education but is also related to attitude. No matter how much driver or road user education or skill you get if you have a bad attitude, you will still have the tendency to be reckless or irresponsible with your actions on the road. One way to curb bad attitudes on the road and to educate road users (particularly errant drivers and riders) is strict traffic enforcement. Many cities already have CCTVs installed at major intersections that allow law enforcement units to be able to monitor traffic behavior and perhaps zoom in to determine driver and vehicle information including license plate numbers.

The crash that killed the single parent in Marikina is not so much as an issue one whether we need segregated and protected bikeways but is more an urgent need to assess the state of traffic education and enforcement in this country.

Articles on the crash and calls for reforms may be found in this link.

 

Common causes of crashes involving bicycles

I found a guidebook of sorts as I browsed one of my shelves for some references on public transport. It was something that I got from a seminar hosted by the Land Transportation Authority (LTA) of Singapore many years ago (I think in 2009.). The book contains tips for road users, whether motorist, pedestrian or cyclist. One page from the guidebook provided a list of common causes of accidents involving pedal-cyclists.

IMG_0632

The page is practically a checklist for cyclists – reminding them of items that they need to keep in mind when traveling. In Singapore and elsewhere, there are rules for cyclists to follow in order to ensure safety on the roads. The assumption here is that other road users, especially motorists, will respect the right of cyclists. Each road user is expected to be responsible with his/her behavior whether as driver, rider, pedestrian or cyclist. Everyone is vulnerable and even the most safety conscious and careful road user may be involved in a road crash.

Readings for the new year

I wrote late last year about how the Christmas and New Year holidays allow me to catch up on some readings. These are mostly contemporary articles on transport and other topics rather than whole books (though I just finished one by George RR Martin during the semester). That post with three articles may be found in this link:

Some interesting readings on traffic engineering

I open the year with another post with a couple of interesting articles. One article reports on the newly opened bicycle ‘autobahns’ in Germany. ‘Autobahns’ basically refer to expressways or freeways. The new facilities for cycling represents what many will term as a paradigm shift for a country well known for its excellent automobiles. The concept of an expressway for bicycles actually makes sense in terms of safety and as a way to eliminate many if not all the factors that tend to discourage people from using bicycles for longer distance commutes. These do have the potential to reduce car usage (and traffic congestion) and ultimately also reduce pollution and fuel consumption. I am interested about the designs of these structures as the designs are also key to the development of similar infrastructure elsewhere including, hopefully, the Philippines.

Germany opens first stretch of bicycle ‘autobahn’

Another article is more thought provoking in the sense that it delves into labor and legal issues surrounding Uber and other ride sharing companies. These issues are valid and need to be discussed thoroughly not just in the US but elsewhere where ride sharing services have proliferated and profited. Many of the points pertaining to labor and compensation are valid, and I would like to think that these extend to the franchising issues that have been raised against ride sharing, which ultimately have implications on their business model. The legalese may be a turn-off to many who would argue that companies like Uber and Grab provide them with a good quality of service. But then that begs the question of whether they would have the same view if taxis were better than what they are now.

Happy New Year and happy readings!

 

Some interesting (and required) readings on traffic engineering

Christmas breaks allow me to catch up on a lot of reading. The previous months comprising our university’s semester were spent preparing for lectures though I had to do some readings related to researches I am involved in. Browsing the net and social media, I came across 2 articles shared by an acquaintance. He is a very progressive planner who has extensively studied and written about the most relevant issues in urban planning, focusing on transport. A third article I found while reading one of the two. These were very interesting for me in part because they are thought provoking in as far as traffic engineering is concerned.

The author seems to call out traffic engineers in general but these articles should also be contextualized properly. The situations mentioned in the articles are to be found in cities in the United States and may not be applicable in other cities in other countries. Traffic engineers in Europe, for example, have been working on exactly the solutions being mentioned in the articles that would make streets inclusive and safe especially for pedestrians and cyclists. The same with Asian cities like Singapore and Tokyo.

In the Philippines, however, there is so much that we can learn from the articles. The mere mention of the design guidelines being used in the US betrays the flaws of highway and traffic engineering in the Philippines. The Philippines’ highway planning manual and other guidelines used by the Department of Public Works and Highways (DPWH) are heavily drawn from US references. Most highway and traffic engineers in the country are educated using curricula that use US textbooks and references. There are even civil engineering programs that use licensure exam review materials as their references! These exam materials are also known to be based on DPWH guidelines and manuals aside from problems “outsourced” or patterned after the Professional Engineer (PE) exams in the US. Few schools have progressive curricula that look to best practices that take into account the complexities of roads especially in the urban setting. Such ‘copying’ of American standards and practices in many cases do not consider Philippine (local) conditions and blind applications to our roads instead of proper adaptation often have lead to unsafe and inequitable roads.
