The Advantages of Subway Tunnels as a Solution on Traffic Congestion in Manila Andrea Margareth Baylon Bernard James Camo Jasper TR Catacata Jhoan Mae Guadamor John Kenneth Abalos Lillian Ellise Ebora Nathaniel Andrei Castillo Pauline Kyle Amper Samantha Lorraine Cabungcal A research paper submitted to the faculty of Senior High School Department, Far Eastern University – Alabang, in partial fulfillment of the requirements for the subject Practical Research 2: Quantitative Research, under the supervision of Ms. Lesley Wong INTRODUCTION One of the worst cities to have traffic congestion is Manila, ranked by The Traffic Index 2019 by TomTom, worldwide congestion in cities ranking. According to a location technology specialist, 416 cities have been surveyed and the Indian city of Bengaluru topped followed by Manila. It was not clear why both Manila and Bengaluru were not considered to be tied top spot. According to a study of the Japan International Cooperation Agency, traffic congestion is the reason why the country loses 3.5 billion daily. If the issue remains by 2035, the loss could reach up to 5.4 billion. In order to balance the queues on its various arms in the event of heavy congestion, modifying the green traffic light duration is suggested. Thus, the vehicle queues should be arranged to
let the minimum number of junctions be blocked by waiting vehicles. According to The National Academies of Sciences Engineering and Medicine (1970), using a control strategy that involves the use of sample data feedback loops at each junction will solve the problem. However, a new problem rises which is the possibility of instability because of the positive feedback effects of traffic coupling. First to be considered is the active behavior of an isolated junction then the analysis is increased to a network of junctions. Using coordinating signals transmitted between junctions can help maintain the stability of the network. Travelling in Manila today is identified by high levels of congestion, slow travel speeds, lengthy travel period, and restricted road capacity. Because of the increasing growth of the population and income, the situation will only get worse. Local traffic management can no longer solve the problem due to their insufficiency. Solutions such as maintaining the supply to the demand should be considered together with increased road capacity. Expanding roads is just not enough to sustain the mobility of vehicles. The advantage of underground tunnels as roads is its significantly low cost.
