一些實際 DSL 包括：交通和道路標(biāo)志、平裝家具組裝圖、象棋游戲（和大多數(shù)其他臺式游戲）以及電路設(shè)計。
The routes they have taken have been mapped out first of all by drivers in conventional cars who gather data about each journey, including road markers and traffic signs.
他們的路線信息主要來自于日常傳統(tǒng)汽車司機(jī)們的行駛數(shù)據(jù)采集，包括路標(biāo)和交通信號。

Mapping nearby features, spotting road edges and lane markings, reading signs and traffic lights and identifying pedestrians is done using a combination of cameras, radar and lidar (which works like radar, but with pulses of light rather than radio waves).
