Counting cars…and other vehicles as well
I saw a couple of these counting instruments set-u by the DPWH, one along Ortigas Avenue Extension and another along Sumulong Highway. These are mobile counting machines that are used to count vehicles along both directions of the roads. These are supposed to be calibrated to be able to distinguish among the various types of vehicles using the roads. I assume the classifications would be according to the types used by the DPWH and not simply a general count of the number of vehicles. I wonder though if these can accurately count smaller vehicles like motorcycles, bicycles and PMD’s like the one in the photo below.
If these can be calibrated to count bicycles and PMDs, it would allow for the establishment of baseline numbers and expansion or seasonal factors for what are now termed as micromobility modes. The recent bicycle counts done through volunteers and during peak hours cannot be expanded simply because there are no reference factors that can be used for this purpose. The available expansion or seasonal factors with DPWH derived from 24-hour counts at strategic locations along national roads only account for motor vehicles. These cover the variations of motor vehicle traffic over long periods of time (e.g., 24/7) that allows one to determine Annual Average Daily Traffic (AADT) as well as typical traffic during certain days of a week (e.g., traffic on a Monday or a Sunday).
