On child-friendly cities

Here’s another article that I want to share. This time it is about child-friendly cities. Here is an article that present many good practice examples in other cities. Many are easily replicable in our towns and cities, and should be considered by local governments in order to enhance safety and health aspects in their jurisdictions.

On the Pasig HOV lane experiment, again

I recently wrote about some thoughts on Pasig City’s HOV lane experiment along Julia Vargas Avenue. Here are a few more considering the experiment didn’t push through last February 28.

Screen cap (courtesy of ABS CBN) showing the starting date for the HOV lane experiment. I think ‘HOV’ is more appropriate than ‘carpool’ since the requirement is for vehicles using the lane to have 4 or more passengers. Having only 2 passengers still qualify as a carpool.

I learned recently that the experiment has been put off to March 26, 2018:

The current set-up has 2 lanes for motorised vehicles including a wide lane for HOV’s (including public utility vehicles like buses and vans). HOV’s here also include cars but those with at least 4 occupants. Here are a couple of photos showing us what could possibly happen should enforcement be weak given the configuration of the lanes along Julia Vargas:

An SUV overtaking the van via the bike lane and the extra space of the HOV lane.

Wide lanes generally encourage higher speeds. I believe the way to go would be to have narrower lanes. And should these be considered, it would be possible to have 3 lanes for motorised traffic with one assigned for HOV’s and another for motorcycles. These are aside from the bicycle lane that I think should also be a protected lane. Protection here may be through the provision of “forgiving” physical dividers in the form of, say, rubber bollards.

Here’s how the Julia Vargas carriageway could be laid out:

Again, these are just suggestions for whoever are in-charge of the experiment-to-be along Julia Vargas Avenue. I hope that they are able to make some assessments even prior to the experiment. Such can be done using simulation software in order to have a handle on traffic related issues that may crop up during the implementation. Still, a big factor would be the enforcement aspects of the proposed policy for motor vehicles. Strict, firm and sustained enforcement would be necessary in order for this to succeed.

On prioritising pedestrians and promoting walking

We begin March with an excellent article that came out from

Walker, A. (2018) The case against sidewalks and how cities can create new avenues for pedestrians,, [Last accessed 2/23/2018].

How do we improve the environment (i.e., facilities) to encourage people to walk? Do we simply clear up sidewalks? Widen them? Build overpasses and underpasses? What should be the context for improving pedestrian facilities for our cities and municipalities? What are the implications to planning and design?

Another walkability tool: Pedestrians First

The ITDP recently came out with a new walkability tool called Pedestrians First. Here’s the link to their site where you can download the tool. The tool was released in the recently concluded World Urban Forum held in Malaysia.

Of course, there are other tools out there including one developed by Clean Air Asia, material on which may be found through the following links:

Walkability Mobile App

Our technical staff and my students are currently using the methodology developed by Clean Air Asia and have covered several major thoroughfares in Metro Manila and a highly urbanized city in studies that have been undertaken in the last 6 years. I already asked them to take a look at the new tool and see how this compares with the ones we are using.

On learning from the experiences of others about transit ridership

I again share an article; this time on transit ridership (or on the passengers using public transportation).

Buchanan, M. (2018) Lessons on Ridership, from the National Literature,, [Last accessed 2/21/2018]

Perhaps we can learn from the experiences of other cities in as far as public transport use is concerned? For example, what impacts emerging technologies and the sharing economy (e.g., ridesharing) have on public transport ridership and how to meet these challenges to retain a majority of public transport users over low capacity modes.

Another crash along NLEX – losing control?

We were returning from Clark last week when we chanced upon a crash site along the North Luzon Expressway (NLEX). We already suspected this as we approached a build-up of traffic along the southbound direction where there is usually free-flowing traffic. Here are some photos of an overturned vehicle on the median. It seems like it is the only vehicle involved as there were no other vehicle in the vicinity that could have been involved. However, it is possible that there was another vehicle involved in a situation where the overturned vehicle’s driver lost control after interacting with the other vehicle. Obviously both vehicles could have been traveling at high speeds (they are on an expressway) so this could have been an example where the combination of speeding and weaving in traffic led to an overturned vehicle (i.e., one lost control).

Emphasising safety during these holidays

Here are a couple of articles that I thought should reiterate the importance of safety whenever we travel. This is especially true during this holiday season when a lot of people are going around – shopping, heading to their hometowns or simply vacationing.
