road and traffic signs

基本解释

So they were less aware of traffic and road signs.
因此，他們就很少注意到交通信號燈和路牌的標記。
Some real-life DSLs are: traffic and road signs, flat-pack furniture assembly plans, a chess game (and most other table games), and electronic circuits design.
一些實際 DSL 包括：交通和道路標志、平裝家具組裝圖、象棋遊戯（和大多數其他台式遊戯）以及電路設計。
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於日常傳統汽車司機們的行駛數據採集，包括路標和交通信號。

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).
