Abstract

Traffic Impact Assessment (TIA) is a vital tool for keeping transport infrastructure and services in step with land development. In the Philippines, some local government units have developed and legislated TIA requirements, but application nationally has so far been inconsistent and ineffective. This paper benchmarked Philippine TIA practice against Australian practice, which has a longer-established, state-based regulatory framework, to identify the gaps driving this inconsistency. The comparison identified several critical weaknesses in current Philippine practice. Recommendations for strengthening TIA practice in the Philippines are then proposed in light of these findings.
