GRU-CNN Neural Network Method for Regional Traffic Congestion Prediction Serving Traffic Diversion Demand

Table 1

Classification of congestion levels in the road network.

Level	Road network congestion level	Percentage of road traffic congestion in 15 minutes
1	Very smooth traffic	[0%, 20%]
2	Smooth traffic	(20%, 40%]
3	Slightly congested traffic	(40%, 60%]
4	Moderately congested	(60%, 80%]
5	Severely congested traffic	(80%, 100%]
