road and traffic signs

基本解释

So they were less aware of traffic and road signs.
因此，他们就很少注意到交通信号灯和路牌的标记。
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.
一些实际 DSL 包括：交通和道路标志、平装家具组装图、象棋游戏（和大多数其他台式游戏）以及电路设计。
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.
他们的路线信息主要来自于日常传统汽车司机们的行驶数据采集，包括路标和交通信号。

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).
