The team M worked on the revitalization project of Tsuneishi area propsed by Tsuneishi HD. As a result of this year's project, we proposed "Tsuneishi Smart Community" system. This systemutilized strong and active local community, which is valuable social capital in Tsuneishi area. Through our project, we clarified five core issues in Tsuneishi area. Communication, traffic, shopping, education and land are their core issues.
We interviewed residents in Tsuneishi for 5 times. At first, we defined four problems from the VOC by using KJ diagram.
i. Traffic problem caused by lack of public transport system and narrow road.
ii. People can't drive a car have difficulty to go shopping
iii. Children must go other area for higher education.
iv. Narrow land restrict to build new buildings and houses
In this project, we defined "revitalization" as improving these problems.
We selected traffic problem as most important. The land problem is given environment, and has huge challenge to improve it. Causal loop diagram shows that the shopping and education problem will be solved by traffic system. While the interview, people mentioned about the traffic problem most frequently. According to the questionnaire responded by Tsuneishi residents, 60% people think that the traffic problem is the most important.
Additional interview and observation conducted after we defined four problems showed us the other problem: communication gap in Tsuneishi area. There are 3 major gaps between sub-communities, such as different generation, different town association, or Tsuneishi Employee and other residents. On the other hand, we found out that there are active local community. They have many event and communication in the community center. It is the wonderful resource in Tsuneishi.
CVCA included interview results shows us that these sub-communities have no relations each other. WCA result is similar.
As a result of concept generation, we reached "On Demand Bus" system as initial idea. On Demand Bus System is the public transportation system with flexible bus operation is regarding user demand. QFD result shows time to destination and distance to bus stop are key quality metric in transportation system design. In this phase this system seems suitable solution. . In the next phase, we used Pugh selection to compare traffic systems. Both of On Demand Bus System and Car Sharing System show similar advantage, so we combined each advantage and propose new system.
On Demand Bus System has challenge on sustainable profit. The system is introduced in the many community, butalmost all of these cases require the subsidy from local govenment Usually 70% of incomes are subsidies. The system is very useful for substitute of the local fixed route bus, but it is difficult to operate for private enterprises.
From the study result we made, we recommend Hitch Life Community System. The system has a concept "we are all friends in Tsuneishi". The system is the membership carpool system in Tsuneishi utilize strong human network. A fundamental use-case is described below. Drivers and users made member registration first. A driver responds to a user's hitchhike usually. User interface is local SNS and Kairanban: a notice around from house to house in the neighborhood. A user can check operation status of a car and make reservation. A driver pick up users could earn local currency as incentive. Moreover, the system uses the bus already operated inside the Tsuneishi HD factory as a On Demand Bus in the high demands time as morning. Income source of the system is user's registration fee, advertise revenue on the car and sales of cooperation stores.
We carried out field survey of the French Covoiturage system as the system's benchmark. Covoiturage is the carpool system using SNS started by a venture enterprise. The system is intended to transport from a local city to other local city in French. At first, users and drivers write their schedule and search for travel partner. Users have to negotiate with a driver from several days before. A user pays a part of highway cost and gasoline cost for a driver. Now, Covoiturage is a governmental promotion enterprise and has 1,000,000 users.
In the early phase of this system, Tsuneishi HD will recommend their employee, which occupies the half of the daytime population in Tsuneishi area becoming a driver to provide drivers need in early phase.
We assume that student who attends school not located in Tsuneishi area will be major user in early phase.
Biggest risk of thinking has uneasiness to the responsibility and safety in case of a traffic accident. It seems that both user and driver feel anxious from result of questionnaire. As a countermeasure, evaluation system of the driver similar to covoirturage could be introduced.
