Questionnaires on the twenty-one independent items and a synthesized evaluation on a living circumstance were conducted widely in cities, suburbs and country sides. Categories for each item were classified on the subjective scale from "very good" to "very bad". Category scores for the eight most effective items were determined by the theory of quantification TJ by Hayashi, concerned with three criteria "good", "neutral" and "bad". The dividing points on the total score for the best prediction of a criterion were obtained following the mini-max method. Finally, the effect of each item on a living circumstance can be compared with each other numerically and a synthesized evaluation of the living circumstance can be predicted. The result was applied to the survey along high ways which caused "very annoyed" noise environment. It was found that its improvement to "neutral" could change the living circumstances from "bad" to "neutral" without changeing the categories of the other items. Then, a joit tunnel was proposed to have unitedly transportation lines for trains, cars and refuse, energy transformation on electric and gas lines, communication lines for telephone, optical fiber and etc., drainnage and water supply, and have the green belt on it. More precise prediction on this method was discussed to have simultaneous surveys with more independent items and less inner cross correlation between the items. Because each item has subjective categories, the possibility to have concrete categories for it is also discussed.
