This study inventoried the off- and on-street parking facilities of the City of Manila, specifically in the districts of Ermita and Malate. The road system in the said Districts was also inventoried and classified whether on-street parking is applicable that took into consideration the use of the road, the land use characteristics of the area, the road traffic volume and characteristics, among others. The study also used remote sensing and geographic information systems for proper documentation and with the intention of developing off-street and on-street parking databases for long term traffic management system of the area. The proper and detailed inventory of current and proposed off- and on-street parking facilities in the area would also ensure proper and efficient parking fees collection. In order to simulate current and future road traffic users, both private and public, that would affect on-street parking, the EMME/3 software was used. The impact of on-street parking on vehicular flow, in terms of delay, was also estimated which is due to the number of on-street parking, the number of vehicles moving in and out of the on-street parking lot, whether the street is a one-way or two way street and whether public transport system is present or not. The study recommended an urban parking management plan for the said Districts in order to improve parking revenues as well as to make efficient use of the road network as well as develop an on-street and off-street road parking inventory system.
