驾车时间计算器.
根据距离和平均速度估算驾车所需时间，提供城市、郊区和高速公路的预设选项，外加停车时间。

使用方法
时间 = 距离 / 平均速度。平均速度是一个输入项，而非隐藏的固定值，因为它才是真正决定结果的因素。
预设值：市区48千米/小时（30英里/小时），郊区80千米/小时（50英里/小时），高速公路105千米/小时（65英里/小时）。这些是整段路程的平均速度，而非限速值。
实际行程通常比限速更慢：路口、红绿灯、施工路段和并线都会占用时间。如果您在规划到达时间，建议使用比标示限速低10%-15%的速度。
请在停留字段中加上加油、用餐和休息的时间——它们会额外加到行驶时间之上。
常见问题
How long does it take to drive 100 miles?
At a highway average of 65 mph (105 km/h) it takes about 1 hour 32 minutes. At a suburban 50 mph average it is 2 hours, and in stop-start city traffic averaging 30 mph it stretches to well over 3 hours.
Why is my real drive slower than the speed limit suggests?
Average speed over a whole trip is always below the posted limit because of junctions, traffic lights, roadworks, merging, congestion and acceleration from a standstill. A good planning rule is to use a speed 10-15% under the limit for the road type you will spend most of the trip on.
What average speed should I use?
Use 48 km/h (30 mph) for city driving, 80 km/h (50 mph) for suburban and A-road driving, and 105 km/h (65 mph) for sustained motorway or interstate driving. Mixed routes fall between — set the field to whatever best matches the majority of your distance.
How much time should I add for stops?
Plan about 15 minutes for a fuel stop, 30-45 minutes for a meal, and a 15-minute rest break every two hours of driving for safety. Enter the total in the stops field and it is added to the driving time.
Does the calculator account for traffic?
Not automatically — it uses whatever average speed you enter. To model rush-hour traffic, lower the speed rather than adding stop time: congestion slows the whole leg instead of pausing it.
