THE Metropolitan Manila Development Authority (MMDA) has announced the implementation of traffic management measures to alleviate expected heavier traffic during All Saints' Day and All Souls' Day (collectively 'Undas') and the Christmas season.

MMDA acting chairman lawyer Romando 'Don' Artes, during a press briefing at the MMDA head office in Pasig City on Friday, said it is necessary to implement effective and sustainable measures to effectively address the expected traffic problems during the Christmas season since the traffic volume in Metro Manila increases during the holidays.
