On the traffic flow predicament at Tikling junction…again
During weekends, a constant frustration have been the incidence of severe traffic congestion along Ortigas Avenue Extension. Weekday evenings are usually better in terms of traffic compared to Saturdays. But last Monday, the congestion was so severe the congestion reached Valley Golf and vehicles had to crawl to Tikling. As mentioned in previous posts on this subject, part of the problem is the sheer volume of vehicles that make the roundabout set-up inappropriate for the junction. Then there is also the issue about the people who are supposed to manage traffic but end up mismanaging it. From what I usually observe, they tend to favour vehicles coming from Taytay via the Manila East Road leg and seem oblivious to the build-up of traffic along Ortigas Ave. Ext. eastbound.
Typical heavy traffic at Tikling Junction
We might finally get a chance to have a solution for this. One of our students took on a topic that will require her to asses the traffic at the intersection to determine, for example, whether the roundabout is suitable or perhaps should be changed into a signalised traffic control. Both analytical approach and microsimulation (using Vissim or the homegrown LocalSim) will be employed. But we will have to wait by May to see some substantial results.

On the efficiency of transportation – a crash course on transportation engineering concepts
There is an excellent article on the efficiency of transportation systems:
Gleave, J. (2019) Space/Time and Transport Planning, Transport Futures, https://transportfutures.co/space-time-and-transport-planning-1aae891194e5 [Last accessed: February 25, 2019].
It is highly recommended not just for academics (including students) but also for anyone interested in transportation and traffic. It’s like a crash course in transportation engineering with a lot of basic concepts in traffic engineering and traffic flow theory being presented for easy understanding by anyone. Enjoy!

Reference on bike-focused street transformations
There’s an update to the “Rethinking Streets” guide with one that is focused on street transformation for bicycles. Here is the link to their site where they now have 2 guidebooks:

On computer games for city planning
There’s another article on a very popular computer game that allows people to play city planner or mayor. I recall playing the game for the first time in the early 1990s. A friend got hold of a bootleg copy of the first version and we soon found ourselves addicted to the game. 🙂
Roy, J. (2019) From video game to day job: How ‘SimCity’ inspired a generation of city planners, Los Angeles Times, https://www.latimes.com/business/technology/la-fi-tn-simcity-inspired-urban-planners-20190305-story.html [Last accessed: 03/13/2019]
Of course, later on we tried experimenting on some concepts to see how the game will go for themes such as transit oriented development (TOD) and combinations of land uses. This allowed us to have an appreciation of how a city will grow and how networks perform given various scenarios. I still believe the game has a lot of value not just from the gaming perspective but also from an academic or practical view. City planning (and not just the transportation or traffic aspect) is a very complicated matter and requires a lot of know-how, wisdom and logic (also others) for a city to function well and for it to grow. Perhaps the newer versions of the game will be even more “realistic” and help develop future planners and administrators.

Lessons to be learned from experiences on public transport abroad
There’s this “old” article that came out last year that is very much relevant as it is timeless for its topic. The title is intriguing as the many if not most US cities are known to be car-dependent. Few have good public transportation in terms of the efficiencies or qualities we see in Singapore, Hong Kong, Seoul or Tokyo (just to mention Asian examples). Clearly, quality of service is the main reason why people are apprehensive about using public transportation. In fact, the attraction of ride shares, for example, are precisely because people want to have what they perceive as safe, comfortable and convenient modes of transport for their regular commutes. Only, for many people, their choice is also limited by the affordability of such modes of transport. Perhaps the same is applicable if you extend the discussion to include active transport. Cities and municipalities would need to provide the right infrastructure and environment for people to opt out of cars, take public transport, walk or cycle.

References linking transportation and health
The Institute of Transportation Engineers (ITE) features several resources discussing the linkage between transportation and health. Here is the link to the page where they list references like reports from various sources as well as tools.
This is definitely a topic that needs more attention and studies in the Philippines in order to have local evidence (there are already strong evidence abroad) supporting active transportation and how it helps make citizens healthier. Of course, that goes without saying that active transport should be integrated with an efficient public transport system. That is so that the increasing share of private transport can be checked (no thanks to Grab and Uber) and we can either retain or increase public and active transport shares.

Railway bridges along the PNR Main Line South
This is a continuation of the series of posts about my recent trip to Bicol where I was able to take some photos for items I generally label. These stock of photos are posted here for several reasons including convenience of access in case I need them for lectures or other presentations. Previously, I had posted on vertical curves along the Andaya Highway. This time around are some photos I took of railway bridges along the PNR’s Main Line South and particularly in Camarines Sur. It was quite challenging to look for or anticipate seeing these structures; many of which are quite old and in a state needing urgent maintenance. Most if not all are steel truss bridges and the ones in better conditions are shown in the following photos. All were taken within the Naga City boundaries.

Vertical curves along the Pan Philippine Highway
We start the month of March with a compilation of photos of vertical curves (mostly sags). These were taken along the Andaya Highway, which serves as the main bypass road in Camarines that allows travellers to bypass, for example, Daet.
These photos do not have captions and I leave it to my readers to have an appreciation of the features of these sections. These include wide carriageways with paved shoulders. There are also sections that have no shoulders. For most photos, the pavement appears to be in good condition. However, the same cannot be said for much of the highway, sections of which are being rehabilitated along with several bridges.

What happens now to the DOST’s AGTs?
The Automated Guideway Transit (AGT) vehicles that were used in the research and proof of concept at the previous test site in UP Diliman are scheduled to be transported back to DOST’s MIRDC soon. The vehicles are still in UP Diliman and are usable for R&D if someone decides to come up with a viable proposal for these. Unlike the hybrid electric train that is the AGT’s contemporary in terms of them being parallel projects, the future is unclear for both AGT models (i.e., there is another, higher capacity AGT already at MIRDC and tested using the test tracks there).
The two AGT vehicles are wrapped to protect them from the elements. These are functional and should still have value in case someone proposed to continue in their testing and refinement. It doesn’t need to be an elevated guideway for development to continue.
Here’s a closer look a colleague managed to take before we turned at the intersection.
What’s next for the AGT? Is there a future for these vehicles? Will the DOST initiate something with the DOTr or maybe with an LGU (Taguig?) to come up with a project that will employ these vehicles in what can be a full system instead of one on test tracks? Let’s hope these assets can still be utilised and not be wasted.

Another look at the Bitukang Manok
I recently featured photos of the old zigzag road along the Pan Philippine Highway that is more popularly known as the “Bitukang Manok”. Those photos were taken on an early morning while we were on our way to Bicol earlier this month. Following are photos of the old zigzag road taken on the afternoon of our return trip to Manila.
Crossroads – at the intersection at the southern end where travellers decide whether to take the Bitukang Manok or the newer and easier bypass road
The sign states: Vehicles with 6 or more wheels are prohibited from using the old zig-zag road.
Sign for the Quezon National Forest Park – this designation is attributed to a former President and local congressman
Here’s a photo of one of the more challenging sections. A team of flagmen manage traffic by giving turns to either direction, ensuring slower speeds and wider turning at the hairpin curve. Travelers often toss coins as a token of gratitude for these flagmen who man this challenging section of the national highway 24 hours/day.
The barriers and signs along Bitukang Manok have been upgraded and are well-maintained.
Approach to the northern end of the old zigzag road
Directional sign at the other end of Bitukang Manok showing the options for travellers and another advisory stating the prohibition of large vehicles along the old zigzag road.

Caught (up) in traffic
