This study discusses the effectiveness of contingent valuation method and contingent rating method in evaluating the landscape esthetics of streets. The research assess streetscape plans from both economic and psychological points of view and analyze the relative importance of design elements such as street vegetation and sidewalk pavements on the economic and preference-based values. The research conducted experiments by using computer-simulated images as virtual alternative of street design projects in Taipei City. The elements selected various types of design with a varying cost of street trees species, interval of trees, height of shrubbery, pavements material, pavements pattern, pavements color of sidewalk. The respondents participating in this experiment were asked to evaluate thirty-two alternatives by two kinds of questionnaires, contingent rating method was for students and contingent valuation method for landscape professions. In the economic evaluation of alternatives, the availability of landscape esthetics preference are seen as benefits, and these can be compared with the material cost of an alternative. This study use six indices for the economic evaluation of street design that include an acceptable cost derived from a contingent valuation method and composite indices related to the cost and benefits(cost(C), preference(P), acceptable cost(AC), P/C, AC/C, AC-C) and clarify their characteristics indicating cost-effectiveness. The results indicate that street trees species, interval of trees, height of shrubbery, pavements material, pavements pattern, pavements color of sidewalk would influence preference and cost-effectiveness. The respondents considered both landscape esthetics as well as material cost when they evaluate economic values of streetscape.In addition, the results suggests that AC-C is highly correlated to low cost plans and that P/C is a moderate index balancing high landscape preference and low cost.
