Item Restricted An econometric model of Philippine domestic air passenger traffic(1981-10) San Buenaventura, Airin A.Item Restricted Effects of oil prices on traffic congestion in Metro Manila(2006-11-06) De Borja, Princess Paulette Q.; Gaurino, Justine Anne T.; Tan, EditaThis paper will analyze the effects of changes in the price of petroleum on traffic volume and car ownership in Metro Manila. Using available measures and a 20-year period time series data, this paper establishes a· negative relationship of petroleum prices with the demand for travel in the short run, and at the same time, seeks to determine the crucial determinants for the demand for automobiles in the long run. Due to data limitations; the study will only be using data from Metro Manila, and therefore, the results may not be applicable to rural areas. It was seen that car ownership is heavily dependent on income in the long run while traffic volume is very responsive to fuel prices in the short run.Item Restricted Estimating traffic congestion costs in the Metro Manila area(1999-03) Toledo, Ian Blaise Falcon; Laya, Amelia Concepcion SandovalThis thesis analyzes, suggests improvements and expands the methods of estimating traffic congestion costs done by Zenaida Manalo. Aside from Manalo's cost components for traffic congestion costs such as cost of man hour loss and fuel loss, this paper also explores air pollution as'a traffic congestion cost. The estimation of man-hour loss was improved by adding vehicle per capacity ratio into the equation and using average hourly wages instead of wage factors. This resulted in a figure far greater than Manalo's estimates. Manalo's estimates were smaller because of the use of wage factors that excessively deflated the opportunity cost of being stuck in traffic. In addition, Manalo's model did not totally capture traffic congestion, since it did not include road capacity into her equation. The estimation of fuel loss was improved by incorporating operating distances under heavy traffic conditions into the equation. This resulted in isolating the fuel loss due exclusively to traffic congestion. Pollution costs was added to traffic congestion costs since it posed a burden of cost to society (health problems and discomfort).Item Restricted Economies of traffic density in a deregulated airline industry: the Philippine case(1996-03) Tinio, Irma Lou B.; Visaya, Blesila F.; Tecson, Gwendolyn R.Item Restricted An econometric model for inter-island ship passenger traffic(1994-10) Vinuya, Ferdinand D.
