Good day. Please have a look at the wiki definitions of highway=busway and highway=bus_guideway. They should only be used where bus lanes are physically separated from all other traffic and for the latter additional rail-like infrastructure is required. This does not seem to be the case in Tacloban.

Bus routes driving on regular roads can be mapped using public transport relations containing the existing highway segments.
