On the opposition to “complete streets”

I recently read an article about the opposition to road diets in California, USA:

Tinoco, M. (2018) “How to Kill a Bike Lane”, http://www.citylab.com, https://www.citylab.com/transportation/2018/05/how-to-kill-a-bike-lane/559934/?utm_source=SFTwitter [Last accessed: 5/20/2018]

So far, we know that at least three cities are progressive enough to implement road diets including Marikina City, Pasig City and Quezon City. Iloilo doesn’t count yet since their bike lane was constructed along the very wide Diversion Road. Our recommendations for Tacloban, if implemented by the city, will probably result in the second most comprehensive application of road diets/complete streets in the Philippines after Marikina, which implemented their bikeways network almost 2 decades ago. There are sure to be many who would be opposed to such schemes as many still have the view that streets are for motor vehicles. This car-oriented thinking is something that will be a challenge to advocates of people-oriented transportation systems. Hopefully, many can learn from experiences here and abroad on how to reclaim space for people leading to safer and more inclusive transport for all.

Cavitex

I had wanted to post about the Manila-Cavite Expressway (Cavitex) but kept putting it off as I had few photos of the tollway. Formerly known as the Coastal Road, it is now operated by the Metro Pacific group, which also operates the North Luzon Expressway (NLEX), the Subic-Clark-Tarlac Expressway (SCTEX) and the Subic Freeport Expressway (SFX). Here are photos I took last February this year when we went to Bacoor with our Japanese research lead. Most of the photos show sections towards Cavite (southbound).

The tollways has 3 lanes along each direction.

On one side is the bay where reclamation projects are proposed or currently under way.

There is basically one toll plaza for the tollway for either direction.

On the Pasig HOV lane experiment, again

I recently wrote about some thoughts on Pasig City’s HOV lane experiment along Julia Vargas Avenue. Here are a few more considering the experiment didn’t push through last February 28.

Screen cap (courtesy of ABS CBN) showing the starting date for the HOV lane experiment. I think ‘HOV’ is more appropriate than ‘carpool’ since the requirement is for vehicles using the lane to have 4 or more passengers. Having only 2 passengers still qualify as a carpool.

I learned recently that the experiment has been put off to March 26, 2018:

The current set-up has 2 lanes for motorised vehicles including a wide lane for HOV’s (including public utility vehicles like buses and vans). HOV’s here also include cars but those with at least 4 occupants. Here are a couple of photos showing us what could possibly happen should enforcement be weak given the configuration of the lanes along Julia Vargas:

An SUV overtaking the van via the bike lane and the extra space of the HOV lane.

Wide lanes generally encourage higher speeds. I believe the way to go would be to have narrower lanes. And should these be considered, it would be possible to have 3 lanes for motorised traffic with one assigned for HOV’s and another for motorcycles. These are aside from the bicycle lane that I think should also be a protected lane. Protection here may be through the provision of “forgiving” physical dividers in the form of, say, rubber bollards.

Here’s how the Julia Vargas carriageway could be laid out:

Again, these are just suggestions for whoever are in-charge of the experiment-to-be along Julia Vargas Avenue. I hope that they are able to make some assessments even prior to the experiment. Such can be done using simulation software in order to have a handle on traffic related issues that may crop up during the implementation. Still, a big factor would be the enforcement aspects of the proposed policy for motor vehicles. Strict, firm and sustained enforcement would be necessary in order for this to succeed.

Progress of C-6 expansion and upgrading

The recent news about the groundbreaking for the C-6 expressway led some people to this site and looking for information on C-6. Here are more photos I took last month (January 2018):

The future northbound lanes of C-6 is currently under rehabilitation and are being upgraded to Portland cement Concrete Pavement (PCCP). The new southbound lanes currently serve the two-way traffic.

The sign is an old one and perhaps still in use as a barrier more than for information

You see a lot of people jogging, walking and cycling along the finished road. It shows the demand for spaces for such activities, including recreation, and a similar situation may be observed along C5 before and along the perimeter of Libingan ng mga Bayani where a lot of people do exercises and other activities along road sections that are closed to vehicular traffic.

With one lane completed the second lane is prepared for pouring of concrete. You can see the formworks along the median.

Other sections have yet to be prepared for concreting but have been stripped of the old pavement (Asphalt Concrete pavement or ACP).

What you see here at right is the compacted base/sub-base layer. The forms have not been installed yet.

I will post more photos later from the next time I pass by the area. From what I’ve hear so far, traffic has eased along the expanded Barkadahan Bridge but there are still bottlenecks to address along this alternative route. There will also be a need to have a higher capacity, less friction connection between C-6 and C-5 as traffic along C-6 increases and it’s become quite obvious that Taguig’s narrow streets cannot handle this increasing travel demand between the two highways. It makes sense to have a higher quality, limited access road for this purpose since Taguig roads are already congested and through traffic poses a safety hazard to the residential areas where vehicles travel through.

On the Pasig HOV traffic experiment

Someone shared a post about a traffic scheme they will be implementing along Julia Vargas Avenue in Pasig City. The proposal is for the avenue to have a high occupancy vehicle (HOV) lane where vehicles with 4 or more occupants are to take one lane and all other vehicles the other. I am not entirely sure about the objective other than to promote high occupancies for vehicles. However, it would be nice to see how travellers will be behaving (e.g., complying) and how Pasig (with MMDA?) will be enforcing this scheme.

This is what a segment of Julia Vargas currently looks like with 2 wide lanes designated for motor vehicles (separated by the solid yellow line) and one narrow lane for cyclists (adjacent to the shoulder):

 

The intent is good but as a major link the scheme can be quite confusing especially for those who are not necessarily frequent users of this road. I assumed the yellow line was painted by the DPWH but it seems it was by Pasig. Perhaps they should have removed the old markings? Or maybe better if they rationalised the carriageway width to accommodate 3 lanes for motor vehicles and 1 wider lane for bicycles? From the photo above, it appears to me that it is possible to have 2 narrow lanes for general traffic and one wider lane for HOVs (in this case defined as having 4 or more occupants) and public utility vehicles. This configuration maximises the capacity of the road while having a the “best” lanes allocated for HOVs and bicycles.

I wish them success on this social experiment. Perhaps there can be valuable learnings from this including the need for connectivity to other links as well.

On the future of city streets

Here is another article, this time on the future of city streets. I had been sharing many of the ideas related in the article in the Transportation Engineering courses that I handle including those pertaining to the Complete Streets concept and road diets. The article is good reading material for my students who need to get out of the box (so to speak) of traditional civil engineering thinking regarding highways and streets. That is, we need to do more people-centred rather than car-centric designs.

Davidson, J. (2018) “What Is a City Street? And What Will It Become?”. New York Magazine. http://nymag.com/daily/intelligencer/2018/01/what-is-a-city-street-and-what-will-it-become.html [Last accessed: 2/2/2018].

Here is a photo I took in Iloilo City a couple of years ago showing the bikeway along the Diversion Road. The facility then was underutilized but was supposed to represent, along with the Promenade along the river and the redevelopment of the old airport site in Mandurriao, the revitalisation of the city. Meanwhile, there have been little done for the downtown streets.

Iloilo City provides a good example of the need to have a more holistic transformation rather than have some exhibition or demonstration pieces for inclusive transport here and there.

Congestion along C-6 and potential for a public transit corridor

We begin February with a post on a road that’s becoming more popular as a major (as opposed to alternate) route to Bonifacio Global City (BGC) and Makati CBD – Circumferential Road 6. I took the following photo at the approach to the Nagpayong Bridge that is current has only 2 lanes (1 per direction). Another bridge is being constructed along the existing one that will increase capacity for the Pasig River crossing to 2 lanes per direction. This is similar to what was done to the Barkadahan Bridge  crossing the Manggahan Floodway in Taytay, Rizal.

The volume of road vehicle traffic is steadily increasing along C-6. The adjacent land use offers a lot of potential for development (hopefully planned) that will feed more traffic along what will become a major thoroughfare in the near future. The land I am referring to are the reclamations on the side of Laguna de Bai along C-6 that are under the jurisdiction of Taguig and similar developments on the opposite side on what was once swampy or marshlands. One wonders if Taguig has a plan for all this or if the city is turning a blind eye and just letting developers do what they want. Most seem to be residential subdivisions and industries-related with a sprinkling of mainly small to medium-sized commercial developments.

Again, I think national and local governments should consider making this a public transport corridor by introducing formal public transport in the form of a scheduled bus service stretching from, say, Bicutan Interchange to Taytay Public Market. The demand along this corridor is steadily rising and only a better connection to C-5 limits an even steeper increase in traffic volume along C-6. The time is now in order to condition commuters about the system and to the unwanted congestion experienced along major roads in the metropolis.
