Which Consumes More Fuel: National Highways or Expressways?
1 Answers
Driving on national highways consumes more fuel than driving on expressways. Here are the specific details about fuel consumption: 1. Expressways: Expressways are generally "straighter," meaning the driving distance is shorter compared to national highways, which naturally reduces the vehicle's fuel consumption. 2. National Highways: The main cost of driving on national highways lies in fuel consumption. Firstly, national highways are more prone to traffic congestion. Once stuck in traffic, frequent braking and acceleration are unavoidable, leading to a sharp increase in fuel consumption. If passing through areas with dense traffic lights, fuel consumption will inevitably spike. Additionally, national highways often have more winding routes, which indirectly increases the driving distance and results in higher fuel consumption. 3. Speed: The maximum speed limit on expressways is 120 km/h. If the average speed is 100 km/h, a 100-kilometer journey takes one hour. The speed limits on national highways are completely different, typically around 60-70 km/h, and in some areas with poor road conditions, the limit may drop to 40 km/h. Due to the complex road surfaces on many national highways, speeds are not very high. If the average speed is 50 km/h, a 100-kilometer journey would take two hours.
