The Short Version
No evidence supports the existence of a traffic study of Open Canal Road in Barangay Pascam II, General Trias, Cavite, let alone one that uses the Highway Capacity Manual as its primary standard. The only references to "Open Canal Road" in the evidence pertain to Malagasang II, Imus — a different municipality entirely. The claim fabricates verified specificity from general observations about HCM usage in Philippine traffic practice, which itself is not uniform, as competing standards like the DPWH Traffic Capacity Manual are also used.
