How long does it take to drive 170 kilometers?

170 kilometers driving time calculation: Based on the highway speed limit of 120 km/h, driving 170 kilometers would take approximately 1 hour and 25 minutes. Travel speed: Travel speed refers to the average speed of vehicles on a specific road section. It is calculated by dividing the length of the road section by the pure driving time (travel time after deducting all stopping time), used to analyze the ease of driving and traffic capacity of that road section. Impact of vehicle speed on road surface damage: The proportion of large vehicles in transportation is increasing, and vehicle overloading is very common. These overloaded vehicles typically drive at lower speeds on highways, causing significantly more damage to road surfaces than standard axle loads. This leads to premature road damage, accelerates the deterioration of road performance, and greatly shortens the service life of pavement.
I often drive on highways, frequently covering distances like 170 kilometers. The speed limit on highways is 120 km/h, but you can't maintain that speed the whole way—you have to slow down in tunnels or heavy traffic. On average, it's about 100 km/h, so 170 kilometers takes roughly 1 hour and 40 minutes. That doesn’t account for traffic at highway entrances or rest stops, so in reality, it’s safer to budget around two hours. If the weather is bad, like during rain, the travel time will be even longer.
Every time I drive 170 kilometers, it takes me over two hours, mainly due to the complex road conditions. On the highway section, I can drive at 110 km/h, but on the national highway off the expressway, although the speed limit is 80 km/h, I often encounter tricycles crossing the road or market traffic jams in villages and towns. In areas with many traffic lights, I can only drive at 40-50 km/h, averaging around 80 km/h overall. 170 divided by 80 is a bit over two hours, but there are often road constructions or temporary checkpoints on the way, so I usually allow an extra half-hour buffer. Before heading out, it's best to check real-time traffic conditions on mobile maps to avoid school areas during peak dismissal times for the most time-saving route.
I mainly drive around the city, and 170 kilometers would be quite a hassle in urban areas. During the morning and evening rush hours when traffic is heavy, you might only cover 20 kilometers in an hour. Even during off-peak hours, with traffic lights and steady traffic, averaging 40 km/h is considered good. That means 170 kilometers would take over four hours—if you leave at noon, you'd arrive after dark. If you encounter an accident, road closures, or rainy weather along the way, the travel time becomes even harder to predict. So, for long-distance travel within the city, it's best to avoid rush hours or simply take the subway or high-speed rail for a faster trip.
