Metro Manila Examples: Edsa Shaw Intersection, Quezon Boulevard Recto Intersection, EDSA Aurora Boulevard Intersection.

To those who worry about flooding, a submersible pump and a floodwater tank is installed underneath the tunnel. When it rains, the tank absorbs rainwater and when the rain stops, the pump puts out water out of the tank. Of course, tank volume has limits to.

EDSA Express Buses

Posted: May 31, 2015 in Uncategorized


In between overloaded MRT Trains on slow EDSA Traffic, MMDA DOTC and LTFRB introduced Express Buses in EDSA last March. It’s a hybrid between a BRT and a Regular Bus, where these buses share the road with the rest of the traffic where BRT has an exclusive route and lesser stops than the regular buses. Express buses promised a faster travel from Fairview in Quezon City to Makati City because of this. Unlike regular city buses, express buses can pass through underpasses and flyovers closed to traffic (Aurora, P. Tuazon & Tandang Sora)

Initially it has 3 different routes depending on the final stop of the bus but was made more flexible but stops remain the same: Ortigas MRT and Ayala Center in Makati.

I have been riding the bus service for two months now, and I should say it’s a big change from overcrowded buses and stress inducing MRT. I doesn’t allevate the EDSA Traffic (vehicle volume stayed the same) but it delivered a somehow faster trip compared to frequently stopping regular buses. I should say this is a marked improvement. Obviously this line only serves the Fairview – Makati Routes so there is limited ridership. This still has room for growth as some areas are traversed by EDSA buses. Buses from Navotas (UE Letre) & Valenzuela (Malanday) could become express bus routes opening opportunities for North EDSA & Quezon Avenue to become bus stops before Ortigas therefore relieving some stress to MRT 3 ridership.


The Circumferential Road 1 Loop

Posted: November 16, 2012 in Uncategorized

The Circumferential Road 1 comprises of Recto, Arlegui, Ayala Blvd. and Bridge, Finance Road and the Luneta Segment of P. Burgos. It links the oldest districts of Manila: Quiapo, Binondo, Sta. Cruz, Intramuros and Luneta. It is also the messiest part of the old City as it is one of the main roads of the old City. It is because of many conflicts at each intersection of the Road.

Seeing that it forms a circular road and forms a complete loop with Bonifacio Drive at the border of Port Area and Intramuros, a complete one way circular road might be suitable for the road. The figure below gives the traffic flow of the figure. Given the following conditions:

  • All will be three lane roads in the loop.
  • The part of Recto at Divisoria will be fully cleared of hawkers (I mean it).
  • All other minor intersections will be fully closed to vehicular traffic.
  • Cars might or might not be allowed inside the loop.
  • Only the following roads will be allowed as entry and exit points to C-1
  1. Radial Road 10
  2. Abad Santos Street
  3. Avenida Rizal
  4. Andalucia (which leads to A. Bonifacio/NLEX)
  5. Morayta (which leads to Espana to Quezon Avenue)
  6. Legarda (which leads to Aurora Boulevard)
  7. Taft Avenue (which also branches to Pedro Gil and SLEX)
  8. Roxas Boulevard

I also did some traffic simulations on the conditions before and after the changes in the routing was done. As a sample I did the Morayta and Recto intersection. Please roll the video.

Before the loop exchange

After the traffic management changes

The loop has lesser conflicts but the old one has more conflicts more traffic gridlocks and queues. Remember that at intersections, the most efficient intersection control are the ones who has lesser signalized intersections. The lesser traffic signals, lesser operation costs and road air pollution and fuel wastage due to queuing and gridlocks. It might also result in better quality of life and improvement in the economy of the old Manila districts inside the loop: Binondo, Intramuros, San Nicolas, Ermita, Quiapo and Sta. Cruz. I think the next post will be the transportation planning of the areas inside the loop.

Bored and trapped in that rush hour traffic along EDSA yesterday, I just thought EDSA’s system of flyovers and underground tunnels are already obsolete and should be decommissioned, demolished and redesigned already. EDSA should have a more extensive North South connection because obviously, at grade roads are already obsolete. While retaining the MRT3, EDSA should have an Elevated Expressway on top of the MRT3. While too expensive to tell, this is one of the ways to finally bring order to the busiest and the most problematic highway in the Philippines. The roads at grade could be reserved for the Buses for a BRT Line and some motorists who do not want to drive in the Expressway above.

Traffic Flows of the design

Alignment: Along EDSA (Circumferential 4) from NLEx to SLEx and Metro Manila Skyway above the Tracks of MRT3

Length: 18 kilometers

Est. Travel Time: 20-30 minutes (based on 80kph maximum speed, current EDSA speed is 20-30kph)

Entry/Exit Ramps at: NLEx (Radial Road 8), Quezon Avenue (Radial Road 7), Aurora Boulevard (Radial Road 6), Shaw Boulevard (Radial Road 5), J.P Rizal Avenue (Radial Road 4) and SLEx & Skyway (Radial Road 3). Optional Ramps at Ayala Ave.
