RETRACTED: Designing Data Visualization Using Artificial Intelligence for Urban Intelligent Transportation Scenarios

Table 1

Data table of traffic operation level division of road sections.

Run level	Smooth	Basically unblocked	Light congestion	Moderate congestion	Serious congestion
Highway	V > 65	50 < V ≤ 65	35 < V ≤ 50	20 < V ≤ 35	V ≤ 20
Main road	V > 40	30 < V ≤ 40	20 < V ≤ 30	15 < V ≤ 20	V ≤ 15
Secondary road, branch road	V > 35	25 < V ≤ 35	15 < V ≤ 25	10 < V ≤ 15	V ≤ 10

Note. V represents the average travel speed of the road section; the unit is km/h.
