  Open Trip Planner was identified as the most promising open source
multi-modal trip planning software. Open Street Map, which provides mapping
data to Open Trip Planner, is one of the most well-known open source
international repository of geographic data. General Transit Feed
Specification, which provides transportation data to Open Trip Planner, has
been the standard for describing transit systems and platform for numerous
applications. Together, when used to implement an instance of Open Trip
Planner, these software has been helping in traffic decongestion all over the
world by assisting commuters to shift from using private transportation modes
to public ones. Their potential however goes beyond providing multi-modal
public transportation routes. This paper aims to first discuss the researchers'
experience in implementing a public transportation route planner for the
purpose of traffic decongestion.The researchers would examine the prospective
of using the system for disaster preparedness and recovery and concrete ways on
how to realize them.
