In order to solve the metrowide traffic problem, the Metropolitan Manila Development Authority (MMDA) has gone out and identified the different traffic-prone areas in Metro Manila in order to find the root of the problem and make it easier to solve.

Seven bottleneck areas can be found on EDSA starting from Balintawak Market Road, Aurora Boulevard, Ortigas Avenue, Shaw Boulevard, Guadalupe, Ayala Avenue all the way to Taft Avenue including roads to and from Manila North Harbor Area, especially Circumferential Road - 3 (C-3 Road), A. Mabini Street, Dagat-Dagatan Avenue, North Bay Boulevard and Radial Road 10 (R-10).

In the southern part of Metro Manila, roads to Ninoy Aquino International Airport terminals, particularly Airport Road, Domestic Road, Andrews Avenue, Tramo Avenue, Sucat Avenue and Sales Road; Alabang-Zapote Road and Circulo del Mundo Avenue all contribute to a high amount of traffic.

Rizal Avenue, Samson Road, Gen. Malvar Street, Mc Arthur Highway, Karuhatan Road, Gen. De Leon, Pio Valenzuela and Gen. De Jesus in the northern part of Manila have also been classified as traffic-prone.

In the eastern side of Metro Manila, Santolan, Gil Fernando Bridge, Marcos Highway, San Juan Intersection, Pasig Intersection and Meralco Avenue all experience heavy traffic.

Meanwhile high volume of traffic can be seen in parts of Quezon City including Boni Serrano Avenue, Araneta Avenue, Timog Avenue, E. Rodriguez Avenue, Katipunan Avenue, C.P. Garcia Avenue, Magsaysay Avenue, Capitol Intersection, Luzon flyover, J.P. Rizal, Ayala Heights Rotunda, Mirriam Gate and Ateneo Gate.

Areas to avoid in Manila are Bonifacio Drive, Roxas Boulevard, Espana Boulevard, Ramon Magsaysay Boulevard, Jose Abad Santos Avenue, Claro M. Recto Avenue, Sen. Osmena Highway and Rizal Avenue (Carriedo).

"The traffic in the metropolis also caused by undisciplined motorists, illegally-parked vehicles, and illegal structures of bus and jeepney terminals," said Atty. Crisanto Saruca, head of the MMDA Traffic Discipline Office.
