Transit subsidy is a common policy, used by many governments to support any increase of transport cost and therefore provide some direct benefit to users. In transportation, subsidies, are granted for many reasons and take an important part of government expenditure. This study is conducted to evaluate three different subsidy plans, to implement in the metropolitan area of Panama; where all the economic activity of this country is concentrated. The subsidy plans proposed by the authorities are aimed to provide financial assistance to the operators, develop new technologies and integrate the new systems (Metro and public bus); to benefit both the operators and users of public transportation systems. The subsidy schemes proposed for Panama were evaluated using the Analytic Hierarchy Process (AHP). This method consists of a hierarchical representation, in which the decision problem is decomposed into different levels according to their common characteristics. Each level is evaluated by experts in transportation and economy of Panama. The experts were required to conduct a pair-wise comparison of the elements and provide the weights to determine the ranking of each alternative. The scheme 1, composed by a fuel tax rebate, a flat fare scheme, an operating subsidy for metro operations and a fare subsidy; was placed as the worst option. The second best option was, scheme 2, formed by a concessionary fare subsidy, capital subsidy for both systems (to invest in fleet and new technologies) and operating subsidy for metro operations. The best alternative according to the opinion of the experts was scheme 3, which offered a conditional operating subsidy, a flat fare subsidy, an operating subsidy for metro operations and a discount for transfers in both systems. Key Words: Transit Subsidies, Analytic Hierarchy Process, Subsidy Schemes.
