| Expressway | Less than 15 | 15～30 | 30～50 | Greater than 50 |
| Express way | Less than 10 | 10～20 | 20～40 | Greater than 40 |
| Main road | Less than 5 | 5～12 | 12～25 | Greater than 25 |
| Secondary road | Less than 5 | 5～10 | 10～20 | Greater than 20 |

The first set color and the second set color may be different colors set in advance according to an application scene or specific requirements. For example, the second set color may be green. The first set color may be yellow, orange, and/or red.
In an embodiment where the setting type is multiple, that is, the setting type may include at least two of clear, slow traffic, congestion and heavy congestion, the method may further include obtaining a road condition type of each of the marked objects.
On this basis, rendering the road segment section corresponding to the mark object with the road condition type being the set type as the first set color may include: rendering the section of the road section corresponding to each mark object into a first set color corresponding to the road condition type. The first set color corresponding to each road condition type may be different.
For example, if the first setting color corresponding to the type of slow traffic is yellow, the first setting color corresponding to congestion is orange, and the second setting color corresponding to severe congestion is red, then the section corresponding to the marked object with the type of slow traffic may be rendered yellow, the section corresponding to the marked object with the type of congestion may be rendered orange, and the section corresponding to the marked object with the type of severe congestion may be rendered red.
In an embodiment of the present invention, the road section corresponding to the mark object whose road condition type is the set type in the road condition rendering area may be rendered as a first set color, and then the other road sections in the road condition rendering area that are not rendered as the first set color may be rendered as a second set color.
