Work trips in Metro Manila are estimated at 4.15 million person trips. In terms of frequency it is the second most important trip purpose. Due to its obligatory nature, trips to work are a major contributor to traffic congestion. Local literature however on the subject matter is rarely encountered, thus there is limited understanding of the basic characteristics of workers and the trips itself. Understanding the nature of work trips will assist in th6~formulation of policies geared towards alleviation of congestion of roads leading to Central Business Districts (CBD). This study analyzes work trips to selected CBD zones in order to gain a basic understanding of the nature and characteristics of work trips and to add to the limited local literature on the subject. The major recommendations include: a) promotion of telecommuting b) encouragement of car pooling c) implementation of counter flow traffic scheme d) provision of traffic information service e) imposition of high parking fee f) further promotion of vehicle restraint programs g) institution of staggered working hours and h) control of car ownership.
