Revising the DPWH Design Manuals
A friend posted about the current initiatives in the US as they embark on revising their Manual on Uniform Traffic Control Devices (MUTCD). This manual along with AASHTO’s Geometric Design of Highways and Streets and their Highway Capacity Manual are something like the holy trinity for Highway and Traffic Engineers. These are also the main references for our DPWH for the manuals and guidelines we use in traffic and highways.
Here are a couple of articles calling for the revisions to reflect recent designs mainly from NACTO, which itself publishes guidelines for roads to be more inclusive rather than car-centric:
NACTO (May 2021) Modernizing Federal Standards: Making the MUTCD Work for Cities, https://nacto.org/program/modernizing-federal-standards/
NACTO (May 11, 2021) A Blueprint to Update America’s Street Manual, https://nacto.org/2021/05/11/a-blueprint-to-update-americas-street-manual/
We don’t have to pattern revisions after the MUTCD but then that requires that the DPWH through its Bureau of Research and Standards (DPWH-BRS) do its part in compiling, reviewing, studying and adopting materials from various countries, and developing suitable standards and guidelines for roads in the Philippines. Do they have to reinvent the wheel? Not so and they can still refer to the US manuals as long as again these are localised for our conditions and situations.

Vienna Conventions on Traffic and Road Signs
There are two important international conventions or agreements that the Philippines is a signatory to. These are the
Vienna Convention on Road Traffic (November 8, 1968):
and the Vienna Convention on Road Signs and Signals (November 8, 1968):
These are important as signatories are bound but the agreements on road traffic rules and regulations and standard signs and signal. I included the links to each agreement as they also include the exceptions taken by different countries such as Thailand and Vietnam declaring they will not be bound by Article 44, choosing to classify mopeds as motorcycles. Apparently, the Philippines did not declare exceptions or objections to any of the articles.

Are roads really designed just for cars?
The answer is no. Roads were and are built as basic infrastructure for transport no matter what the mode. However, the standards for dimensions (i.e., number of lanes, widths, etc.) are based on the motor vehicle capacity, and structural standards (i.e., thickness, strength, reinforcement, etc.) are based on the weights they are supposed to carry over their economic lives. The pavement load as it is referred to is usually based on the cumulative heavy vehicle traffic converted in terms of the equivalent standard or single axles or ESA. An ESA is 18,000 pounds or 18 kips in the English system of measurements or 8.2 metric tons in the Metric system.
A typical local road – is it really just for cars or is it also for walking and cycling? Or perhaps animal drawn transport?
A colleague says many of the posts in social media pitting bicycles with cars are already quite OA (overacting). I tend to agree as I read how people generalize roads being car-centric. Roads have been built basically to serve a avenues for transportation. They were improved over time in order to have more efficient ways to travel by land. It didn’t hurt that vehicle technology also developed over time and bicycles somehow became less popular than the cars and motorcycles. The motorcycle itself evolved from bicycles so in a way, it is the evolved and mechanized form of the two-wheeler.
In a perfect world, people would be sharing the road space and it would be equitable among different users. In a perfect world perhaps, it won’t be car-centric as there would probably be better public transport options and transit will be efficient, reliable, comfortable and convenient to use.
The reality, however, is that we do not live in a perfect world and transformations like the ones being pitched on social media are nice but are also not as inclusive and equitable as their advocates claim them to be. I’ve always said and written that you cannot simply change transportation without also implementing changes in land use and housing in particular.
Why do we need wide roads connecting suburbs and urban areas? Why is there sprawl? Why do people live in the periphery of CBDs or the metropolis? It is not just about transport though it seems easier to focus on this. Even transportation in Japan, with Metropolitan Tokyo and its equivalent of NCR plus as a subject, needs to be properly contextualized for land use and transport interaction and development. It seems that even with a comprehensive and efficient railway network, there are still shortcomings here and there. We don’t have such a railway network (yet) so we need to find ways for easing the currently long and painful commutes many people experience on a daily basis. That means continued dependence on road-based transport and trying to implement programs and schemes to improve operations.

On the “safe system” approach in road safety
We kick-off the UN Global Road Safety Week with a road safety feature. Here is an excellent read from Johns Hopkins University’s Hub:
(May 13, 2021) “Safe system” approach could dramatically reduce road deaths while improving equity, Hub, https://hub.jhu.edu/2021/05/13/safe-system-roads-could-reduce-road-accidents-deaths/ [Last accessed: 5/14/2021]
To quote from the article:
“The Safe System approach engineers road systems so that they are safe when used intuitively, the way people tend to use them. A Safe System minimizes the chances for mistakes by drivers, pedestrians, and bicyclists, and reduces the intensity of crashes when they do occur.”
There are so many situations and locations around the country that could be improved using this approach. The safe system approach is actually embedded in the country’s current Road Safety Action Plan (RSAP).

Article on sustainable mobility
Here is a quick share of an article from Cities Development Initiative for Asia or CDIA. The title may already be quite cliche by now (i.e., along the lines of the slogan “move people, not cars”) but the message is clear and cannot be emphasized enough especially as people grapple with the impacts of the pandemic on transportation. For the reader, take note of the avoid-shift-improve framework, which is quite useful in describing what needs to be done in order to address the climate impacts of transportation systems.

On building the ideal city from a transportation perspective
There’s a not so old article that popped in my timeline of articles I’ve read the past years. I thought I would make a quick share of it here. It is a good read and something that will never be irrelevant for as long as we have not redeveloped our cities and municipalities for transport equity and sustainability. Here’s a takeaway from the article:
“The ideal city is a place where lots of different kinds of people with lots of different amounts of money can live and work. It has to be easy to get around without a car, even for people whose bodies can’t ride bikes or hop over potholes, and for people who have kids to drop off on the way to work and groceries to buy on the way home, and maybe flowers to buy next door to the dry cleaner’s. These are places where people want to live, because it’s nice there. The fact that those places also adapt to and mitigate climate change instead of causing it is a bonus.”
Here’s the article from last year:
Rogers, A. (April 1, 2020) “Build Cities for Bikes, Buses, and Feet—Not Cars,” Wired, https://www.wired.com/story/cities-without-cars-san-francisco-jeff-tumlin/?bxid=5bd6761b3f92a41245dde413&cndid=37243643&esrc=AUTO_OTHER&source=EDT_WIR_NEWSLETTER_0_ENGAGEMENT_ZZ&utm_brand=wired&utm_campaign=aud-dev&utm_mailing=WIR_Classics_042921&utm_medium=email&utm_source=nl&utm_term=WIR_Daily_TopClickers [Last accessed: 4/30/2021]

On when to use masks when outdoors
Here is a useful graphic from the US Centers for Disease Control and Prevention. The graphic described situations for when masks are required. I don’t want to use preferred because it means people may opt out of using masks. It is a useful reference even for those in other countries that do not have enough clear information from their governments about wearing masks and how it helps protect vs. getting infected by Covid-19. It is applicable to people searching for a legit reference to mask-wearing in outdoor situations.
This information becomes more relevant as people start getting vaccinated and at the same time look forward to getting together with family and friends in social events such as eating out or having picnics. Of course, this also applies to exercise as well as commuting via active transport modes (i.e., walking or cycling).

Is there a supply problem with public transport in NCR plus?
I initially wanted to use “Philippines” or “Metro Manila” instead of “NCR Plus” for the title of this post. I dropped “Philippines” in order to be more specific and also because I am not so aware of the situation in other cities outside Mega Manila. I also decided vs. “Metro Manila” because transport for the metropolis is tightly woven with the surrounding areas where many people working or studying in MM actually reside. These include the towns of Bulacan, Rizal, Laguna and Cavite.
So, is there a supply problem with public transport in what is dubbed as NCR+? The photos in social media appear to describe a lack of public transport vehicles with many people lined up along major roads, queued at terminals or train stations. These photos do not lie where they were taken. Indeed there is a big problem about supply along certain corridors due to certain factors such as limited number of public utility vehicles (mainly jitneys and buses) allowed operation and health protocols that limit the passenger capacities of vehicles. The latter also applies to rail services where despite rolling stocks being back to pre-pandemic operations, are limited to the number of people they can carry. Crush loads are a no-no during these times.
Traffic congestion and its effects on PUV turnaround times, however, is another major factor for what may seem like a lack of supply. Most road-based public transport operate in mixed traffic. As such, their operations are susceptible to traffic conditions along their routes. So it is very likely that during the peak periods, PUVs get stuck along the peak direction and take much time to return despite the lighter traffic along the return trip. The problem for some routes though is that during peak periods both directions are congested. This further exacerbates the situation for public transport as vehicles would have to go through a two-way gauntlet of sorts, resulting in a lot of people taking longer to get their rides. And so for those who have access to private transport do go back to using private vehicles.
Definitely and obviously, there is a mode choice issue here because many people appear to have taken private transport as their mode of choice instead of public or active transport modes. This is mainly attributed to the perception that public transport is unsafe or less safe compared to your own vehicle in the context of the current pandemic. We qualify the current health situation here since that seems to be the main driver for people choosing to take their cars apart from that other perception of the poor quality of service provided by public transport in general. For active transport, the reality is not everyone or not a lot of people will choose to walk or cycle along roads that are generally regarded as unsafe despite efforts to put up bike lanes. Those who are having problems commuting are those dependent on public transport also because of their long commutes between the residential outside or in the outskirts of Metro Manila and the CBDs in the metropolis.
The dilemma here is determining which routes would actually require additional vehicles. While the general perception and temptation is to add vehicles everywhere, it’s the actual numbers that need to be estimated based on the information that needs to be collected (as against available data, which can be unreliable). The situation and the data for different routes varies much.
Case in point is the experience along the Antipolo-Cubao route that used to be served by jeepneys. Buses now serve that route after the government rationalized the service. Initially, there were fewer buses operating along the route that had a large catchment area for passengers. Additional buses were deployed in order to address supply issues (again many passengers were not able to get their rides for the same reasons we mentioned earlier). Now, there seems to be enough buses for the peak periods but a surplus during the off-peak. Passengers along other routes are not as lucky as those served by the Antipolo-Cubao buses.
Public transport operations will not survive such variations in demand if they continue to operate under the old “boundary” or rental scheme. So, there has to be a subsidy somewhere for them to operate under these conditions. And that’s where service contracting comes in. While I agree that this is essential for transport reform, we still have limited resources, and it will not be sustainable in the long run if we cannot make people take public transport over private vehicle options.

On how communities should be?
This post is related to my recent post about Philippine cities and municipalities already somehow being 15-minute units. I am sharing another article I’ve read and reread for its current relevance.
Litman, T. (March 15, 2021) “A Complete Community is All Mixed-up,” Planetizen, https://www.planetizen.com/node/112565?utm_source=newswire&utm_medium=email&utm_campaign=news-03222021&mc_cid=628c8ee4b1&mc_eid=9ccfe464b1 [Last accessed:
The article is loaded with references that you can download and use in research or practice. And there are these two tables – Walk Score Ratings and Public Amenities – that are quick guides or references to what is desired to be achieved in communities.
Enjoy!

On what local governments can do to improve road safety
Here is a very interesting article on how a small city in the US was able to reduce traffic deaths by investing in people-oriented transport programs and projects:
Kessler, E. (April 6, 2021) “EYES ON THE STREET: How Hoboken Has Eliminated Traffic Deaths,” StreetsBlog NYC, https://nyc.streetsblog.org/2021/04/06/eyes-on-the-street-how-hoboken-has-eliminated-traffic-deaths/ [Last accessed: 4/14/2021]
The article is pretty much self-explanatory. I won’t be commenting more about this except that many of the items mentioned can be taken on by many cities and municipalities in the Philippines. You don’t have to be a highly urbanized city with a big population and so much resources to come up with a plan and perhaps improvise in order to reduce costs of implementation. The most important thing is leadership since leaders like the mayor will be responsible for and making the critical decisions for the town. That is why he was elected in the first place, and the same goes for the other elected officials who are supposed to represent the interests of all their constituents and not just those who own cars.

Caught (up) in traffic
