Real-world sensor dataset for city inbound-outbound critical intersection analysis

Sathorn Model is a project that has attempted to find a sustainable solution for traffic congestion problems in the Sathorn area, Bangkok. The activities are managed by the Faculty of Engineering, Chulalongkorn University. Sathorn Road serves as the gateway linking the residential area on the western side of the Chao Phraya River and the river-eastern side's business area. As a result, up to 150,000 vehicles drive every weekday on Sathorn Road. The Sathorn-Surasak intersection has both inbound and outbound traffic flow. There are a total of three types of sensors installed on the approaching lanes of the Sathorn-Surasak intersection in the Sathorn area: CCTV cameras, thermal cameras and induction loop coil sensors. Traffic volume data are collected every 5 s from CCTV sensors for 37 months from September 2016 to September 2019. Traffic volume and occupancy are collected every 5 s from loop coil sensors for 110 days from May 2016 to September 2016. Also, traffic volume and occupancy are collected every 5 s from thermal cameras for 26 days from May 30, 2016 to June 24, 2016. The dataset has temporal and spatial coverage of Sathorn road's main urban areas, including weekdays, weekends, and public and national holidays.
