In this paper we made a survey of cellular automata (ca) traffic models which can be classified into single-lane, (multi-lane) and city traffic models.

对基于元胞自动机的交通模型进行综述，将其分为单车道模型、多车道模型和城市交通模型三类。

Based on the NS model of traffic flow, we propose a new single-lane cellular automaton model to study the effect of deceleration strips upon traffic flow.

本文在NS模型基础上建立了一个新的单车道元胞自动机模型以研究减速带对交通流的影响。

But when I arrived, my mood plummeted. The road was filled with runners in a race while the cyclists were relegated to a single lane.

但当我到达那里的时候，我的心便一沉：环道挤满了参加赛跑的人，而自行车手们却被转移到一条单车道上。

Quang Ngai is a three-hour drive from the nearest airport along a dangerous single-lane highway.

ECONOMIST: Tourism could do a lot of good if Vietnam handles it properly

It is a single-lane, pot-holed highway winding perilously around peaks up to 5, 000 metres (16, 000 feet) high.

ECONOMIST: Georgia��s not-so-great north road

The roundabout sits on a single-lane section of the A417 dual carriageway between Swindon and Gloucester that is used as link between the M4 and M5.
