Number coding in the Philippines

The Number Coding Scheme, officially named the Unified Vehicular Volume Reduction Program (UVVRP), is a traffic management program in the Philippines that aims to reduce the amount of vehicular traffic in Metro Manila, the metropolitan area of the country's capital. The program is enforced by the Metropolitan Manila Development Authority. The basic idea behind the program is that vehicles whose plate number ends in a particular number is barred from using the main streets of Metro Manila on particular days. For instance, vehicles whose plate numbers end in 1 or 2 cannot be brought out to the main streets on Mondays. The program's original proposal mandated that the color of the roofs of public transportation, like jeepneys and buses, is used as the basis for barring of these vehicles. Hence, the program is also often known as the Color Coding Scheme.
