126. カーシェアリング

カーシェアリングは、各人が個別に車を所有する代わりに、複数人が時間を分けて同じ車両を利用する交通制度です。組織、会員サービス、アプリを通じて予約し、固定駐車場所または指定運用区域内で借りる方式があります。

自家用車所有の必要性を減らし、共有車専用駐車区画が設けられる場合があります。規則、許可、駐車制度は国や都市によって異なります。

What is carsharing?

Carsharing is a system in which several people use one or more shared cars at different times rather than each user owning the vehicle.

How does carsharing work?

Users normally reserve a shared vehicle for a particular journey or period through a carsharing organisation or platform and return or leave it according to the rules of that service.

Can parking spaces be reserved for carsharing vehicles?

Yes. Some countries and municipalities provide parking spaces specifically reserved for authorised shared vehicles. The signs, permits and conditions vary by location.

127. チェアリフト

What is a city limit?

A city limit marks the boundary of a city, town, village, locality or municipality. On roads, it is often indicated by a place-name or boundary sign.

Does a city-limit sign always mark a built-up area?

No. A city-limit or locality sign may simply identify a place or administrative boundary. A legally defined built-up area can use a different sign or definition.

Does passing a city-limit sign always change the speed limit?

No. In some countries a locality or boundary sign has consequences for traffic rules, while in others it mainly identifies the place. Drivers must follow the traffic signs and rules that apply in that country.

Is a city limit the same as a municipal boundary?

Not always. Some signs indicate an administrative municipal boundary, while others identify a city, town, village or locality without exactly following the municipality's legal boundary.

What is the difference between a city limit and a built-up area?

A city limit identifies the boundary of a named place or administrative area. A built-up area is a traffic-law concept that may affect rules such as default speed limits. The two boundaries can coincide, but they do not have to.
