Abstract

This study assessed the effectiveness of Metropolitan Manila Development Authority (MMDA) Resolution No. 22–15, which designates lanes for bicycles, public utility vehicles (PUVs), motorcycles, and private vehicles along Commonwealth Avenue, Quezon City’s busiest road. Enacted to improve road discipline, optimize traffic flow, and reduce motorcycle accidents, the policy was evaluated based on empirical findings after implementation. This research provided empirical evidence by examining awareness, lane visibility, enforcement, maintenance, and availability of shared and dedicated lanes. The study analyzed these aspects to determine the resolution’s overall impact. A quantitative descriptive design was employed, using purposive sampling of 80 respondents from Metropolitan Manila Development Authority (MMDA) Resolution No. 22–15 Commonwealth Avenue, Quezon City: 15 motorcycle riders, 15 MMDA enforcers, 15 PUV drivers, 15 private vehicle drivers, 10 bicycle riders, and 10 truck drivers. Data were collected through a validated structured questionnaire, administered face-to-face with immediate retrieval. Analysis included frequency and percentage distributions, weighted mean, and t-tests. The study's Results showed that most respondents learned about the resolution through MMDA advisories, community announcements, and media platforms. Implementation was generally rated as satisfactory, with positive feedback on efforts to monitor lane use and enforce compliance. Road users observed improved order and adherence to lane rules within the area. However, challenges such as worn lane markings, heavy traffic volume, and occasional deviations from designated lanes were identified. A positive relationship was found between awareness levels and how effective the policy was perceived to be, showing that better information sharing helps boost compliance. The Findings indicate that MMDA Resolution 22–15 is effective in organizing traffic and enhancing safety on Commonwealth Avenue. Strong enforcement and signage improved lane discipline, while media advisories successfully informed road users. However, faded markings and congestion hinder full compliance. Recommendations include continuous public education, stronger local coordination, and data-driven maintenance strategies. Incorporating diverse road user perspectives will further refine policy implementation and advance sustainable urban mobility in Metro Manila.
