On predicting how new developments will affect pedestrians

I’ve been involved in a number of traffic or transport impact assessment (TIA) projects in the past. In these assessments, not much is usually written about the impacts to pedestrians though we make sure that there is a section discussing their needs (e.g., sidewalks, crossings, footbridges). Unfortunately, even with specific recommendations, there is no assurance that the proponent will revise their designs. The typical TIA in the Philippines is undertaken after there have been architectural plans already prepared if not completed. By completed here, I mean they are practically final from the perspective of the client or proponent. The exception it seems is a big mall chain that seems to constantly revise their plans and for which our recommendations are almost always considered and incorporated in design.

I am sharing this recent article on the development of a new traffic model to predict the impacts of new developments on walkers.

Wilson, K. (April 26, 2021) “New Traffic Model Predicts How New Developments Will Affect Walkers,” StreetsBlog USA, https://usa.streetsblog.org/2021/04/26/new-traffic-model-predicts-how-changes-affect-walkers/ [Last accessed: 5/12/2021]

From the perspective of doing TIAs, I think that there should be a conscious effort of including the needs of pedestrians (walkers) and cyclists in impact assessments. Too often, (and I too am guilty here), there is but a minor mention of their needs and recommendations can be disregarded by both proponents (e.g., little or no change in designs to accommodate pedestrian requirements) and the local government (i.e., no push to make sure pedestrian needs are addressed).

On the tech side, there is a local development that can be used for counting pedestrians and cyclists. The TITAN project funded by the DOST-PCIEERD developed a tool that can count pedestrians and cyclists in aid of studies involving them. Such tools can be useful for data collection regardless of whether there is a new project or a TIA being undertaken.

More congestion along Ortigas Avenue Extension?

There are two malls currently under construction along Ortigas Avenue Extension – SM East Ortigas and Waltermart Taytay. Nearing completion is the SM East Ortigas, which looks like a very big mall. It is the former Ever mall beside Riverside Subdivision and close to one of DMCI Homes’ first developments. It will open on December 2 and there are already a lot of promotional tarps announcing this along major roads including C-5, Felix Avenue and, of course, Ortigas Avenue.

Waltermart is further up towards Tikling Junction. These two are actually from the same mother company SM, which has somewhat diversified its retail business so it now includes the SM malls, Savemore, Waltermart and the newly minted S-Mall. These two are sure to generate a lot of traffic and cause more congestion with the SM East Ortigas already in an area where Ortigas Ave. Extension is regularly congested. I am not aware of any studies conducted with respect to this mall but I assume there is a transport impact study somewhere. Personally, I would ask SM to look into the case of SM Novaliches for something sort of a solution to the traffic problem right in front of the mall. Quirino Highway is widest along the section where SM Novaliches is, with the mall providing a very generous setback to accommodate multiple lanes for traffic to flow smoothly at least in front of the mall. That seems possible with SM East Ortigas especially since there is practically only 2 lanes for the westbound direction of Ortigas Ave. Ext. at this area.

Waltermart is a different thing because it is in an area where there is generally no congestion along Ortigas Ave. Ext. I also assume there is a traffic study somewhere providing traffic management schemes or alleviation measures in case congestion occurs due to the mall and its high density residential development component (it is part of a complex called “The Hive”).

I am speculative about the expansive lot vacated by Mitsubishi Motors beside the Panasonic complex. I wonder if any of the big developers are acquiring it and perhaps developing it into a major mixed use project. There is also the lot where Consolidated Tobacco used to be just across Countryside Subdivision and close to SM East Ortigas. Such future developments require careful study for its transportation impacts and the Municipality of Cainta should take a proactive stance for major developments that will generate  a lot of traffic. Ortigas Ave. Ext., even after some widening, remains as a road with high potential and regularity for congestion. Only a mass transit system can probably decongest it but that will take some time to realize.
