I’ve written about land use and parking along Katipunan Avenue, which is part of Metro Manila’s Circumferential Road 5. Katipunan extends southwards to Blue Ridge, St. Ignatius and White Plains (the latter subdivisions just across the street from Camp Aguinaldo) where there are also many establishments along either side of the road. Most of these establishments are restaurants that attract significant private vehicle traffic. Note that there are no public transport routes along Katipunan/C5 in the Blue Ridge, St. Ignatius and White Plains areas. As such, establishments are more likely to attract people with cars rather than those taking public utility vehicles.
Many of these establishments are on lots formerly occupied by residential buildings (i.e., houses) considering the predominant land use in the areas. These were eventually purchased and converted for commercial use, resulting in layouts that generally do not include adequate parking spaces. The consequence of shortcomings in parking have been the propensity for on-street parking such as shown in the following photo in the Blue Ridge area.
Such case and many others like it along Katipunan (and other Metro Manila or Philippine cities roads) are the result of both poor planning and lax enforcement of traffic rules and regulations in this country. Being a primary arterial, Katipunan/C5 should be clear of such unnecessary sources of roadside friction that effectively decreases road capacities while also increasing the risk of crashes as vehicles maneuver, or in some cases wrestle, for parking spaces.
