Amid the recent effort to initiate an integrated medium and long term urban
development planning, the authority has been developing rail-based mass transit system
(i.e. Light Rail Transit and Metro Rail Transit), and operating some short-term TDM
measures to reduce vehicle usage in Metro Manila’s road network. These measures
include the Unified Vehicular Reduction Program (UVRP), also known as “colorcoding”,
and “odd-even number” scheme. UVRP is aimed at banning vehicles to enter
selected road network one day per-week on the basis of their plate number ending,
whereas odd-even scheme is the banning of vehicles based on even or odd ending of their
plate number.
