Data Description
We provide 5 traffic scenarios in total in the first stage, where we extract real vehicle trajectories from different intersections and time periods in Hangzhou, China. The relevant files are located in the 'data' folder of the github repository.
| Traffic scenarios |
|---|
| hangzhou_bc_tyc_1h_8_9_2231 |
| hangzhou_kn_hz_1h_7_8_827 |
| hangzhou_bc_tyc_1h_10_11_2021 |
| hangzhou_bc_tyc_1h_7_8_1848 |
| hangzhou_sb_sx_1h_7_8_1671 |
Each scenario includes both road network (roadnet.json) and traffic flow file (flow.json), whose formats are defined in Roadnet File Format and Flow File Format respectively. The road network shares the same structure equipped with four types of roads (East, West, South, North) and two kinds of lanes (Through, Left). According to the road network, the traffic flow file contains eight types of traffic flows (East-Trough, East-Left, West-Trough, ...).
What's more, the name of each scenario conveys the location, time and traffic volume of this scenario. For instance, "hangzhou_bc_tyc_1h_8_9_2231" defines a scenario where the intersection location index is "bc_tyc" in Hangzhou and the traffic flow starts from 8am to 9am with 2231 vehicles entering into this scenario within this one hour. Specifically, the detailed description of the traffic flow in each scenario is illustrated in the following figures:
