A friend posted the following two graphics showing commuting characteristics derived from a recent survey they conducted online. The 327 respondents are not much compared to the more comprehensive surveys like the ones undertaken by JICA and there are surely questions about the randomness of the survey. Online surveys like the one they ran can be biased depending on the respondents. This was mainly done via social media and through certain interest groups so statistically there may be flaws here. Still, there is value here considering there is often a lack of hard data on commuting characteristics especially those that are recent or current. We need these to properly assess the state of transportation or travel in Metro Manila and elsewhere.

What’s lacking? Information on car and motorcycle users? And why the long waiting times? Are these really just because of a shortage in the supply of public transport vehicles thereby necessitating additional franchises? [Graphic and data courtesy of Toix Cerna via Facebook]

Again, the mode shares reported are incomplete. With the exception of walking, car and motorcycle shares are substantial and significant. There is some info here about trip chains (i.e., the average of 2 rides per commute) but it is unclear what percentage of the trip is made using whatever mode is used. [Graphic and data courtesy of Toix Cerna via Facebook]

The absence of information about cars and motorcycles is glaring due to their significant share of commuters. Yes, the term ‘commuter’ actually refers to someone who regularly travels between home and office. By extension, this may also apply to travels between home and school. The term is not exclusive to public transport users as is often assumed. Walking between home and office qualifies as a commute.

I am curious about how commutes using cars and motorcycles would compare to public transport commutes. The comparison is quite useful to show, for example, the advantages and disadvantages of car use (this includes taxis and ride share). More detailed information may also reveal who among car or motorcycle users use these vehicles out of necessity rather than as one among many choices for their commutes. One thinking is that if public transport quality is improved, then many people will opt to use PT rather than their private vehicles. However, there is also the observation that in many cases, those already using PT are the first to shift from the lower quality service to the better one. I also wrote about this as I posted my worries about how successful can Line 7 and Line 2 extension be in reducing car use along their corridors. Perhaps the ones who will truly benefit are those who are already taking public transport, and car and motorcycle users will just continue with these modes?

In Part 2, I will share some data we collected more than a decade ago for a study on jeepneys in Metro Manila. I will use the information to explain another angle of this issue on public transport supply and demand.
