Embodiment Construction
[0138] The present invention will be further described below in conjunction with the drawings.
[0139] Reference Figure 1 ~ Figure 5 , A road network traffic situation prediction method based on deep learning, including the following steps:
[0140] S1. Obtain multi-source traffic data and road network static configuration information to construct a traffic flow parameter model; said multi-source traffic data acquisition includes Internet link speed data (AutoNavi Map API, Baidu Map API), detector flow data ( SCATS detector), signal control program data; the static configuration information of the road network, including road network spatial geographic location information, intersection number, road section grade, road section length, road section number, lane number, lane function, etc.;
[0141] S2. Analyze the correlation of road network congestion and build a basic forecast group;
[0142] S3. Construct a deep learning traffic situation prediction model based on a two-stage att...
