Katipunan parking predicament

Developments along Katipunan Avenue in Quezon City are good examples of fragmented land use and transport planning in Philippine cities. The developments, particularly the high rise condominiums have been the subject of much opposition from residents of subdivisions in the area as well as two major institutions of higher learning that have defined the stretch of Katipunan that has been developed in the 15 years. I mention 15 years because this is the period during which most of the high density developments along Katipunan have been constructed, apparently with the blessings of city hall. It is also in the last decade that schemes such as road widening and the U-turns were implemented.

On-street parking along Katipunan at lanes that used to be part of what was a west service road. In many cases, onstreet parking has been the result of a violation of a very basic provision of the National Building Code, which prescribes the minimum number of parking slots for establishments such as restaurants, shops, banks and offices. Despite being quite outdated and disconnected with more progressive parking generation principles, the NBC should have been a basis for the local government to assess whether minimum guidelines are satisfied, and perhaps impose penalties on those who are not able to comply such provisions. This is a fundamental case where individuals (owners of parked vehicles) impose external costs (e.g., congestion and crash risk) upon the general public.

Another look at onstreet parking just beneath the pedestrian overpass across from Ateneo’s Gate 2 – restaurants along Katipunan are major traffic generators and despite the presence of public transport (jeepneys and tricycles) a significant number of trips generated by these establishments use private vehicles including cars, vans and SUVs. Katipunan’s pedestrian facilities are inadequate as there are practically no sidewalks, thereby forcing people to walk along the road. This exposes many and particulrly students to risks like getting sideswiped by vehicles driven by reckless drivers.

Waiting vehicles effectively occupying 2 lanes of Katipunan – many employ drivers who can stay with the vehicles while the occupants eat, shop or transact at establishments. In most cases, standing vehicles are practically parked vehicles as they occupy road space. High-rise residential condominiums along Katipunan may have complied with minimum parking requirements stipulated in the NBC but their trip generation characteristics considering the commercial establishments located at the same buildings surely require many more parking spaces than what are available.


Congestion along Katipunan’s southbound side – may be caused by onstreet parking, standing (waiting), or vehicle maneuvers with respect to the limited parking slots fronting most establishments along the road. One tutorial center located near a U-turn slot, for example, generates significant vehicle traffic that it affects both U-turn and through traffic. Meanwhile, traffic enforcers seem either ineffective or helpless in their efforts to manage traffic, including preventing vehicles from taking 2 lanes of Katipunan.



Standing/waiting vehicles in front of a new development along Katipunan – the new building hosts several establishments including a major bank, a book shop, a popular gym, and several restaurants or cafes. Despite the potential for vehicle attraction, only a few parking spaces were provided, leaving all other vehicles and their drivers on their own to find parking spaces or just occupy road space in front of the building. The footbridge across Ateneo’s Gate 3 has been extended to the building but this obviously has marginal impact in reducing vehicle generation and parking demand.

Another photo showing the parking situation in front of the new building – while traffic is generally a manifestation of economic activity, one opinion is that many developers are irresponsible by designing buildings that have inadequate parking and resulting in the general public bearing the burden of traffic externalities. Add to this local governments that turn a blind eye on such discrepancies in design (who reviewed the design that obviously violated the building code?) only to be on the receiving end of complaints. In some cases, LGUs probably will be forced to shoulder costs of providing solutions that developers should have covered in the first place if they were responsible enough or made responsible for mitigating negative impacts of their projects.

In the end, it is inevitable that we need to address the root of the problem, which pertains to land use planning and the zoning policies LGUs are implementing. Consistency is one thing and being circumspect about established guidelines is another. Sustainable development, after all, does not pertain to continuous transformation from low to high density development but more about balancing elements that would preserve the character of neighborhoods and communities, particularly and most importantly to ensure that quality of life is not compromised.

Still on Katipunan

Katipunan is again the subject of attention thanks to the Sunday newspaper article by Prof. Randy David in his column at the Inquirer. The problem is not really new and I have been familiar with the congestion and its derivatives from the time I first studied in UP Diliman in 1988 and up to now when I continue to pass through the avenue between home and workplace.

I was able to dig up a 2003 study on Katipunan conducted by the National Center for Transportation Studies (NCTS) of UP for a consortium chaired by then DENR Secretary Bebet Gozun. The study was the group’s response to the MMDA’s effort to install their U-turn scheme along Katipunan, encouraged at the time by the scheme’s apparent success along Commonwealth and EDSA while not acknowledging the problems experienced along Quezon Avenue. The photos below were taken during the time when the study was being undertaken and are very much the same picture of Katipunan today during the peak periods.

Figure 2: Ateneo-bound vehicles blocking through traffic along the service road and the Aurora flyover

The study involved contributions from most if not all stakeholders including Ateneo and Miriam, the private sector and civil society groups, the Transportation Science Society of the Philippines (TSSP), and some government agencies particularly the DENR, who convened the group to formulate an alternative to the MMDA’s initiative that was personally being pushed by its then Chair Bayani Fernando. I reproduce below, word for word, the conclusions and recommendations from that 2003 study:

{Conclusion}

“After a thorough evaluation of the traffic problems along Katipunan as well as the solicited and unsolicited solutions from stakeholders, it becomes clear that the answer to the Katipunan traffic question is not the introduction of the U-turn scheme into the system. Indeed, while the U-turn scheme has met with relative success along major thoroughfares including Marcos Highway and Commonwealth Avenue, it has also contributed if not created congestion along Quezon Avenue. The notion that “success in EDSA and Commonwealth means there is no reason why the scheme won’t work in Katipunan” would not hold water in the light of the requirements for effective implementation of U-turns. Simply said, the traffic volume along Katipunan during the peak periods alone will assure that the U-turn scheme will cause more congestion rather than mitigate it.  

{Recommendations}

  • Optimization of traffic signals – coordination of signals need to be implemented particularly for the intersection pairs identified in this report. The Traffic Engineering Center (TEC) must be consulted with respect to the operation of the traffic signals along Katipunan.
  • Restriction of roadside parking – parking restrictions must be strictly enforced and establishments along Katipunan should adhere to the required parking slots corresponding to the traffic they generate.
  • Removal of parts of the islands to improve flow – geometric improvements to ease flow (i.e., increase road capacity) may be explored. Note that this report is not entirely opposed to removal of parts of the islands. However, their outright removal with the trees for the sole purpose of the U-turn scheme is not acceptable to most stakeholders. This must be carefully evaluated.
  • Construction of an internal road between Ateneo and Miriam – the internal road will allow common vehicles to circulate within the campuses thereby eliminating traffic that would otherwise make several entries and exits to the campuses via Katipunan.
  • Open additional gate at Ateneo – the possibility of opening another gate at Ateneo between the existing Gates 2 and 3 must be explored.
  • Encourage carpooling or car-sharing – it is strongly recommended that Ateneo and Miriam consider carpooling or car-sharing schemes. It has been found that traffic along Katipunan is primarily composed of private vehicles will low occupancies bound for the two schools. While the surveys showed high return rates from grade school and high school students, very low returns came from college students. It is these people who account for a majority of the vehicles that clog Katipunan and they should take part in the formulation and implementation of such schemes that would lead to a significant improvement to traffic along Katipunan.
  • Strict implementation of the zoning laws – this last recommendation points to the inconsistency in the granting of building permits to developers of high-rise condominiums along Katipunan. This is a constant issue and a controversial one since residents in the area and the two major schools (Ateneo and Miriam) have always opposed the “spot zoning” practice along Katipunan.” (NCTS, Study on the Traffic Management of Katipunan Avenue, 2003)

The study recommended alternative solutions in lieu of the U-turn scheme for Katipunan Avenue that was at the time being pushed by the MMDA as the solution for traffic congestion in the area.  The recommended measures considered different aspects: traffic management per se, geometric improvements or road construction, travel demand management, land use, and other measures. However, it seems that 8 years after there has been practically no change in conditions along Katipunan Avenue.

The support and commitments of the different stakeholders (academic institutions, residents, business establishments, professional organizations, government agencies, and concerned citizens) are essential for the successful implementation of the recommendations contained herein. It is only through a strong partnership that sustainable and long-term solutions to the traffic problems in Katipunan Avenue can be achieved.

However, it is realized that there should be some sacrifices involved including a dramatic or drastic change in the travel behavior of those mainly responsible for the congestion. The vehicle trip generation of both Ateneo and Miriam are the roots of the problem and their continuing resistance to proposed solutions while not offering any viable countermeasures or proposals will only serve to perpetuate congestion in the area even as the external costs associated with the traffic they generate spread to a larger area. Recent studies at the UP Diliman, which is an open campus, has shown that private vehicle through traffic (i.e., traffic that has nothing to do with UP) has also grown and most of these are Ateneo and Miriam-bound trips.

It seems awkward and even confusing to see that 8 years after what was perhaps the last (maybe even the first?) serious look into Katipunan traffic, conditions have only worsened. This is due to additional developments in the area including high density residential projects that also tend to generate a lot of traffic, and commercial establishments that do not provide sufficient parking spaces. But although these contribute to congestion, their vehicle generation pale in comparison to that of the schools in the area. This is perhaps a case where one is able to see the flaws of others and yet refuses to look in the mirror to see for oneself something that needs critical attention.

School traffic generation – Part 1

One thing I will miss about summers is the relatively light traffic along Katipunan Avenue, which is where I pass through almost everyday between my home and workplace. There is still some congestion during the mid-day and the afternoons but these are typically due to truck traffic as Circumferential Road 5 (C5) is a truck route. During the rest of the year, however, with the exception of most weekends and holidays, severe congestion is experienced along Katipunan during the peak periods, particularly in the mornings between 6:30 AM and 7:30 AM. This is due primarily to the traffic generated by schools along Katipunan Avenue, most notably the Ateneo De Manila University and Miriam College. The following photos show typical traffic conditions along C5 during the peak periods.

Traffic along the southbound service road leads to a U-turn slot under the overpass where many vehicles turn, heading in the general direction of Ateneo. Most turn here in order to enter the university via its Gate 1, which is the main access to the Grade School. On most times, congestion is caused by these vehicles turning right at Gate 1 as they effectively occupy the two lanes of the northbound service road and block all other traffic. This is shown in the following photo where it is clear that vehicles bound for Ateneo and turning at Gate 1 are the main cause of congestion. Beyond Gate 1, the traffic lanes are practically free of congestion.

The afternoon peak is exacerbated by traffic generated by these schools that lead to longer periods of congestion as the number of private vehicle traffic dramatically increases when there are classes between June and April. Meanwhile, there is a noticeable decrease in traffic during the weekends and holidays. Such phenomenon is mostly attributable to the trip generation characteristics of schools, and especially those that tend towards the generation of much private vehicles. Ateneo and Miriam along Katipunan are just two examples. The traffic they generate and the consequential congestion is replicated in other places as well, giving headaches to motorists and commuters passing along major roads affected by these schools. Ortigas Avenue, for example, is usually congested during the weekdays because of traffic generated by LaSalle Greenhills, and ADB Avenue at the Ortigas Center is usually congested due to traffic attributed to Poveda.
