但是，高速公路的提案预计会收到来自道路安全维护者和环保人士的强烈反对。他们指出汽车在高速公路上以更高的速度行驶时，并不会明显提高燃油效率。
But the motorway proposal is expected to receive stiff opposition from road safety campaigners and environmentalists who point out that cars are far less fuel efficient at the higher speed.
K21可以以每小时70公里的速度在铺设的道路上行驶，喷气推进系统能每小时加速7.8公里，以这速度可以穿越过一条河流。
The K21 can travel as fast as 70 kilometers per hour on paved roads and cross a river at a speed of 7.8 kilometers per hour with the help of its water-jet propulsion system.
在城市道路总长度一定，机动车平均行驶速度一定的情况下，希望城市道路网的通行能力越大越好。
For given total length of city roads and average speed of motor vehicles, maximizing the traffic capacity of the city road network is always desired.
你应该使用一个对于道路上其他车辆相对安全的速度行驶。
You should travel at a safe speed relative to the motion of the other vehicles on the road.
人行道被完全占用时，行人占用车行道通行，使道路的通行能力降低，同时使车辆的行驶速度降低，行车延误增大。
When the pavement is occupied absolutely, pedestrians occupy vehicle lanes. Thus the passing capacity of the road is reduced; the speed of vehicles becomes lower and the travel delay increases.
驾驶车辆在道路上行驶时，车速应当按照规定的速度安全行驶。
When driving a vehicle on the road, the driver should drive safely at the prescribed speed.
路面减速带是安装在道路上目前广泛使用的道路强制控速设施，对于减缓车辆的行驶速度、减少交通事故的发生有着良好的效果。
Pavement speed-control hump which is installed on the road is currently widely used as one of the compulsive speed control facilities.
驾驶车辆在不同道路行驶时，应当自觉遵守速度规定，不超速行驶。
When driving a vehicle on different roads, the driver should consciously obey the speed limits and do not exceed them.
