Newly built cities need to build a different level of sanitation system, as seen in the enormous adverse impact that the COVID-19 pandemic (a global pandemic) has had on the global economy. Everything in the city should be designed from sanitary viewpoint. For example;
Houses are to be prepared in lock down situation.
Public transportation is to minimize physical contacts among people.
Offices and factories are to operate normally even in pandemics.
The most important thing is to quickly find and isolate the first infected person. Even after more than one infected person is found, the city must be able to ensure that citizens can carry on their daily lives and work normally.
These goals cannot be achieved with a series of innovative measures, such as highly efficient 911 services or hospitals with remote diagnostic facilities. ABC Cities require a complete redesign of everything in our society, such as the way the workplace works, the housing structure, the legislative and court systems.
The first principle is to divide population into small groups which communicate one another in physically separated manners such as self driving logistics, remote medical diagnoses and treatments, telecommunication etc.
The second is to make every space negative pressure.
The third is to redesign everything from door knobs to judiciary courts from the viewpoint of sanitary.
The city provides houses to citizens near their works, and a group of citizens belong to the same work space reside in the same residential areas. That is, an industrial facility and a residential area is one set. See ABC Housing for detail.
Different from current schools, those of ABC city are a field of social exchanges among students who reside in dormitories. Like citizens, a group of students reside and study together in a separated space. For example, a group of K6 students may share the same space to study and stay. See ABC Campus for detail.
Traditional white-color works such as banks, accounting offices, patent offices are online and unmanned autonomous system. See ABC Government for detail.
The city has a large sports complex at its downtown to encompass all the citizens. However, in preparation of pandemic and blocking, every residential block also has a small sports and leisure facility including swimming pool and running machines. See ABC Residential Area for detail.
In principle, every space is equipped with a small bathroom. Toilets in the city are somewhat special facilities because every ABC city is a tourism city as well as an educational one. So, there will always be many visitors.
See ABC Toilet for detail.
After designing and positioning blocks of the city, all kinds of tangible assets should also be redesigned.
All cars and vehicles are shared. From the viewpoint of travel distance, there are two kinds of transports. One is for short travels such as traveling in an industrial and residential area, and the other is for traveling between blocks or areas.
All vehicles are one or two-seated.
Sanitized after every usage.
All the knobs in the city is quarantined in the same type and model. All gates are equipped with face recognition devices with thermometer function.
All spaces are in negative pressure not to mention of toilets. In toilets, toilet bowls are again in negative pressure, vacuum toilets. And, interestingly, even toilets and toilet bowls are linux machines in the city. See ABC Toilet for detail.
