I remember posting about “submersible bridges”, dike roads and the like. There were two roads atop 2 dams that were part of 2 reservoirs in : the Canili River Reservoir and the Diayo River Reservoir, which are dwarfed by the much larger Pantabangan reservoir and dam nearby. These two reservoirs are at the border of Nueva Vizcaya (Alfonso Castaneda) and Isabela (Maria Aurora), which also happens to be the border of Regions 2 and 3 (Cagayan Valley and Central Luzon, respectively). Here are photos of the roads atop the dams that are part of the Pantabangan-Baler Road.
Vehicles may only pass a single lane with shoulders on either side of the lane. And so there are people posted at either ends of the sections to manage the one-way traffic.
The reservoir is visible on the left side of the photo

Some fish pens on the Canili reservoir side

There’s a short two-lane segment between the Canili and Diayo reservoir roads

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!
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.

The signs announcing the closure of the Tandang Sora flyover along Commonwealth Avenue are doing the rounds of social media. So are the traffic management plans (i.e., the re-routing maps for the area) that are being shared by many and soliciting a variety of reactions. The reactions are often angry or sad for those likely affected by the closure and the re-routing via Luzon Avenue, Congressional Avenue and Philcoa. The demolition of the flyover to give way to the future MRT-7 station will definitely lead to traffic congestion and longer travel times to a lot of commuters, whether using public or private transportation. However, there are only few comments so far about the impacts on pedestrians. Will the pedestrian footbridges be demolished, too? Will they be redesigned or replaced considering the high volume of pedestrians crossing this major intersection? Following are photos taken underneath the Tandang Sora flyover as we waited to make a U-turn. These show the pedestrian footbridges in the area that allow people to safely cross the wide Commonwealth Avenue.

There are many signs installed on the footbridge including the speed limit for Commonwealth Avenue and a reminder to fasten seatbelts. Others are directional signs including those designating the lanes for public utility vehicles and motorcycles.
There is another steel footbridge that is of more recent design and construction connecting to the old truss bridge. This allows pedestrians to continue on to cross Tandang Sora. This example is actually one that invites questions pertaining to design. Why have two distinct designs instead of building on the previous one? Another case of “pwede na iyan” ?
Here’s another view of the two footbridges – one spanning Commonwealth and the other across Tandang Sora. Will these be demolished, too, to give way to the MRT-7 station? And will the MRT-7 Station design include a provision for non-passengers to cross Commonwealth and Tandang Sora? This seems to be the most logical way to design the station; integrating pedestrian (and cycling) needs to the infrastructure. But then again, that remains to be seen and perhaps someone can share the design of the Tandang Sora station for this to be scrutinized.
I found this nice article about some of the most popular simulation games; especially SimCity:

While there are still those who dismiss these as merely games, they fail to appreciate the really complex algorithms and processes that could now mimic real world situations. That includes governance of cities that is a very important factor to its development. Land use planning or transport planning alone cannot provide the solutions for a city’s problems associated with, among others, its growth. The success reflects on the administration and leadership that should be able to anticipate and respond to issues while consolidating and rationalising resources, which are often limited.
The MMDA recently stated they were planning to apply the road diet concept to EDSA by narrowing the current lane widths in order to add one lane per direction. While the idea seems to of good intention, the mention and application of road diet is flawed. I have previously shared an article on social media showing the definition and examples of complete streets:
Clearly, complete streets are for the benefit of everyone (i.e., inclusive) and not biased for motor vehicles. Here is a photo of F. Ortigas Ave. at the Ortigas Center in Pasig City showing the correct application of the Complete Streets and Road Diet concepts to an urban street. Note the elements for cycling and walking that are very prominent in the re-design of the street.

We hope to see more of these re-designs in many other cities and towns in the Philippines. It is not a really difficult concept to apply or adopt as technically these are not complicated. However, there needs to be a change in the mindset of planners and engineers when they do these exercises considering how car-oriented our designs are. It is easy to say we want more people-oriented transportation facilities until it dawns on us how dependent we are on cars and resist the efforts to realise more sustainable designs.
Here’s another quick post where I share this interesting article on Elon Musk’s Boring Company. Central to the article is the notion that certain things related to transportation needs to be reinvented. This was written in March last year. To quote from the article:
“The Boring Company is emblematic of the Silicon Valley conviction that everything must be reinvented, literally: Airbnb is building a hotel, Uber is moving closer to operating like a bus service, and Elon Musk is slowly inventing the subway all over again…”
Here’s the article:
