A little bit of history – on how the US interstate highway system came to be

Here’s one of those quick shares that I usually post here. I am a bit of a history buff and mixing that with transport will likely lead to a post like this. Here is a short article about an event in the history of the US Army that happened 100 years ago: (2019) Celebrating Highway History: The US Army’s 1919 Cross-Country Convoy,, [Last accessed: July 12, 2019]

The article was particularly interesting for me because of two items: the road conditions and the man behind the US inter-state highway system. It took them a little over 2 months to cross the continental US because of poor road conditions. Many people have no sense of history and appreciation of what has been accomplished over the years and how difficult it was to travel at the time. I haven’t done the cross country trip but I have close friends who’ve done it and are thankful for the generally good roads they could use for the experiential road trip. Meanwhile, the person in the article – then Lt. Col. Dwight D. Eisenhower – is a man who made his mark in history at first as the Supreme Commander of the Allied forces in the European Theater in World War 2, who would later on become President of the US. I read elsewhere that the US interstate highway system was designed so aircraft may use them as runways in cases when the US were at war and the enemy had bombed their airports and airfields (just like what the Japanese did in the Pacific).

Do we have similar accounts for our roads and bridges in the Philippines? Were there key persons who may or may not be larger than life figures instrumental in developing our road infrastructure with their vision and leadership (Marcos doesn’t count because of his bogus military record and corrupt regime)? It would be nice to compile these and perhaps it should be a collaboration between the Department of Public Works and Highways (DPWH) and the National Historical Commission (NHC). They could even get the history departments of local universities involved for us to understand the evolution of transportation in this country.

Evidences of demand for Line 2 beyond Masinag (again)

My commute between my home and office usually takes me to Masinag where I make the choice between traveling via the typical Marcos Highway route or via the alternative Marikina/Tumana route. Here is a scene that I usually see whenever I pass by the informal UV Express terminal just past the Masinag junction along the westbound side of Marcos Highway and just before the Decathlon sports facility currently under construction.

Passengers waiting for UV Express vans or AUVs to return around 8 AM. The latter serve the Cogeo – Makati (Greenbelt) route, which could take 2 or 3 rides using other modes of public transport (e.g., one ride to Cubao and another from Cubao to Makati)

Note how many people cannot get a ride around 8 AM. If only there were more efficient options then these people would likely take them but for now the obvious and practical choice for them is the UV Express. Others, of course, can just walk further to SM Masinag where there is a P2P bus service also heading to Makati. Recently, a new “experimental” route was opened between Cogeo and SM Aura in Taguig using modern jitneys.

Once completed, Line 2 should be able to provide an alternative for these commuters but there is still the issue of a seamless transfer in Cubao. There is no direct connection between the Line 2 and Line 3 stations with the former connected to the Gateway Mall while the latter is connected to Farmers. That is a significant walk between the two stations.

But where do the commuters in the photo come from (origin?)? Most likely don’t reside around Masinag Junction though there are many residential area around this location. Many are ferried here by tricycles, jeepneys or private vehicles. Many likely have their own cars but opt not to drive to/from Makati. That is actually a good thing and something that needs to be sustained rather than give a reason for these people to use cars for their commutes. And so there is a need to extend Line 2 perhaps to Cogeo, and a branch to Marikina. The Marikina branch, as I’ve mentioned before, could terminate at the Marikina Sports Center. Meanwhile the extension to Cogeo should not stop there but continue further towards Antipolo’s new government centre. This corridor’s population is steadily increasing and the transport demand must be addressed not by low capacity modes but by a mass transit system. The low to medium capacity modes should be in support or at most supplementary to the high capacity system with the Line 2 as backbone.

Reservoir roads – Part 2

Previously, I posted about the reservoir roads we crossed when we traveled to Baler, Aurora last April 2019. It’s been a while since that post so before I forget, here are more photos of those reservoir roads taken during our return trip from Baler.

The two lane highway becomes a single lane section at the Diayo River Reservoir road

There is a checkpoint at the 2-lane section bridging the Diayo reservoir road with the Canili River reservoir road

Vehicles entering the Canili reservoir road – this again is a one-lane, one-way section where vehicles from either direction would have to give way to either.

Reservoir roads – Part 1

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

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, [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!

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.

On the Tandang Sora flyover’s closure

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.

View of the steel truss footbridge that goes underneath the Tandang Sora flyover

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.
