In this some decades, the way of using public space is changing from automobile oriented perspective to human oriented perspective and the use of public space with its perspective became popular. In japan, municipality's permitting authority for utilization of public space became dramatically widespread by deregulations of the low about public space. Now we need to make an evaluation method of people's activity in public space as livable space.
In this study, we aim to establish “the activity evaluation method of public space by the human oriented perspective” by referring to evaluation method for existing pilot projects research and analyzing and organizing the result of activity evaluation research of “IKEBUKURO East Green Boulevard Sidewalk cafe pilot project in 2015 Spring”.
The following five points became clear from this study.
First, we identified some problems for pilot projects in Japan; for example, single year's budget framework and short-term restricted program.
Second, The conventional evaluation method was by questionnaire and traffic survey only. First: In the pedestrian traffic volume increase or decrease, accurate users' condition in open café can't be grasped. Second: Whether this pilot project contributed to improvement of space cannot be evaluated from the activity aspect since the conventional questionnaire survey can't do an objective observation, survey, although it can show user's satisfaction and what they ate based on user's subjection. Third: Correlation of each user's attributes and actual use condition is not clear.
Third, The western's evaluation method for public space improvement program by Jan Gehl's do not only activity evaluation, but also a suggestion for improvement of public space by mapping activity in public space and connecting that activity data with urban space structure, including pedestrian traffic volume survey, activity survey, questionnaire survey that are three survey called "public life survey" overall.
Forth, There is nearly twice the difference in sample, number between questionnaire and activity survey. Questionnaire survey is not applicable to grasp user number but applicable for qualitative data, such as satisfaction and thought of users.
On the other hand, an activity survey of our study can gather all user data and also have user activity data that can only get from this objective observation, survey, and can analysis multiply through various data that is get by one time. Fifth, conventional evaluation method can show user number from the traffic volume survey, but from our research, deferent findings came out. The tendency of increase or decrease of pedestrian traffic and number of open cafes user are not necessarily match and increase of pedestrian traffic is not necessarily to correspond to volume of use of public space from the result traffic volume survey and activity survey.
