RP NCTS 1994-02: Evaluation of Signal Parameters at Intersections of Metro Manila

The operation of the intersection is often the critical factor in determining the over-all capacity and performance of the road network. Traffic engineers are continually faced with the problem of controlling flows at intersections in order to improve the road network performance. The continuing increase of population and car ownership in the Metropolis urgently needs government action to provide the increasing demand for intersection facilities to facilitate and control traffic movements. Metro Manila adapted the Area Signal Control System starting 1980. Since then, the government is continually trying to solve this problem of facilitating the flow of traffic at the intersections of major thoroughfares. In spite of the poor economic situation in the country, the government is doing its best to ease the road users' discomfort, frustration, loss of travel time and high fuel consumption brought about by the deplorable traffic situation in the metropolis. In this study, the aim was to assess the current situation of signal setting at intersections in Metro Manila, to determine if the signal parameters used are at its optimum. It focused only on signal parameters, namely; phase length, cycle time and phase pattern which the signalization condition of the intersection is greatly dependent on. Through re-evaluation of signal parameters, it could be determined if these intersections need necessary physical improvement or redesign of intersection to deal with and perhaps improve the deplorable traffic situation in the metropolis
