Car accidents happen around the world, it does no matter if it is a third-world or first-world country. Stopping accidents from happening is impossible, but prevention and lessening the chances of road accidents are the next ideal step. Hence, this study in Sta. Rita and Porac Mega dike was conducted to assess the effectiveness of photoluminescent line markings to lessen the accidents in the area due to this area having virtually few streetlights, having an elevated road that is several feet above, and being a common route for cars, trucks, and motorcycles. Raosoft was used to determine the minimum recommended population. With a total population size of 20,000, a margin of error of 10%, and a 90% confidence level, the minimum recommended sample size is 68. The major instrument that has been used in this study was a survey questionnaire. The questionnaire was validated by a research expert, a statistician, and an engineer. This study proved the effectiveness of photoluminescent line marking and is also helpful in reducing accidents along the Sta. Rita and Porac Mega dike. Likewise, it can be used as a guide for the motorist. It can also be easily seen because it is glow-in-the-dark paint. Further, findings about the durability of the photoluminescent line marking indicated that it is reliable in terms of quality and longevity.
