The speed standard of expressway is 60 km/h- 100 km/h, and the average speed of expressway is above 80 km/h, and the highest speed can reach 120 km/h.
2. On the link from project to construction, the expressway is stricter than the expressway:
Expressway is an intercity expressway, and the land problem involved is not only a problem of a single city, but also a common problem of many cities along the route. The construction of expressways must be coordinated by superiors (usually provincial or even national), and several cities should be United. After the project declaration, on-the-spot investigation, EIA publicity and other links, the cities will make a unified final plan.
Freeways are mainly divided into urban expressways, intercity expressways and inter-provincial expressways, so it will be easier to declare projects.
3. Different seals:
The whole expressway is closed and the entrance and exit are controlled. At some designated intersections, only cars are allowed to enter and leave the expressway.
There is no such requirement for expressways.
Extended data:
Highway infrastructure:
1, lane usage function is more detailed.
Expressway usually has a clear division of labor, including sidewalks, non-motor vehicle lanes and motor vehicle lanes. Motor vehicle lanes are also divided into motorcycle lanes, bus lanes, large lanes and small lanes. In terms of speed setting, there are slow lanes, fast lanes and overtaking lanes, and they are equipped with perfect speed limit signs and speed measuring equipment.
There are usually no traffic lights on the expressway.
One-way expressway is generally divided into two functional lanes, namely the main lane and the auxiliary lane. The main lane is used for normal driving and the auxiliary lane is used for turning. There are usually no traffic lights on expressways. When encountering a small branch, there is no opening in the middle partition, and it enters and exits between the small branch and the main road through an auxiliary road.
