Road traffic accidents (RTA) are very common especially in the major cities of the Philippines such as the cities that compose the National Capital Region or Metro Manila. Based on the 2015 records of Metro Manila accident recording and analysis system (MMARAS), a total of 95,615 traffic related accidents occured within Metro Manila. All of these road traffic accidents incur an equivalent monetary cost depending on their type of accident that collectively affect the financial assets of the country. A study previously done by the Institute for Global Environmental Strategies (IGES) in Japan shows a set of equations that can be used in estimating the total cost of accidents. To be able to localize the method of quantifying the costs of RTAs established in Japan and make it applicable in the Philippines, the values incorporated in the equations were based on the data gathered from the roads used in the Philippines. The equations formulated may be used to estimate the anticipated total cost of accidents after implementation of a road safety project. Through this, one can compare the costs incurred from various road projects and select the most inexpensive and economic one. Multiple linear regression was used to model the relationship of the link length and annual average daily traffic volume (AADT), with the total cost of accidents per segment. Based on the analysis, it was concluded that the AADT only had a significant effect on non-fatal and damage to property accidents, while the link length was only significant for fatal and damage to property accidents.
