In support of bike lanes

Here is another interesting article about bike lanes but from the perspective of a non-cyclist. I believe this (support for bike lanes) is a view shared by many but not much articulated. The assumption is usually that car-owners would like to have less of other’s cars on the road so they could benefit from the presumed reduction in congestion should more people take up cycling. But then the same can be said for public transportation and its users as well. That is, car-users would want others to take public transport so as to also reduce road congestion; allowing them faster trips/drives.

On child-friendly cities

Here’s another article that I want to share. This time it is about child-friendly cities. Here is an article that present many good practice examples in other cities. Many are easily replicable in our towns and cities, and should be considered by local governments in order to enhance safety and health aspects in their jurisdictions.

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.

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 riding bicycles slowly

I saw this interesting article on cycling/biking that I thought was quite relevant to the situation we have on campus. The University of the Philippines Diliman campus has a bike lane along the inner side of its Academic Oval that has been used by various cyclist types. There are those who use their bikes for commuting or going around campus (e.g., students traveling between buildings for their classes, messengers bringing documents, etc.). There are those biking in a more relaxed manner (i.e., for recreation). And then there are those who bike for fitness including those racing around the oval. It is from the latter that UP Diliman has received complaints about conflicts with joggers, motor vehicles and fellow cyclists. But then UP has maintained that the bike lane is not for racing or taking laps around the oval. It was created to have a segregated (and in the future maybe protected) lane to enhance mobility more than any other purpose.

UP Diliman’s Academic Oval now features a bike lane between a jogging/walking lane and the lanes assigned for motorised traffic. The ice cream vendor on a NMT 3-wheeler is running on the bike lane.

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.

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.

Another crash along NLEX – losing control?

We were returning from Clark last week when we chanced upon a crash site along the North Luzon Expressway (NLEX). We already suspected this as we approached a build-up of traffic along the southbound direction where there is usually free-flowing traffic. Here are some photos of an overturned vehicle on the median. It seems like it is the only vehicle involved as there were no other vehicle in the vicinity that could have been involved. However, it is possible that there was another vehicle involved in a situation where the overturned vehicle’s driver lost control after interacting with the other vehicle. Obviously both vehicles could have been traveling at high speeds (they are on an expressway) so this could have been an example where the combination of speeding and weaving in traffic led to an overturned vehicle (i.e., one lost control).
