Available dates and intended usages of each data type.

Sensor	Data	Available Dates	Intended Usages
Manual collection	Volume Signal data Queue length	31-Jul-2014	Data collection for understanding the whole area of traffic conditions all at once before we started collecting the real-world sensors data of critical intersection. The indicators undertaken to measure the large coverage area of the road network can be applied to identify the inbound-outbound intersection of the city’s business district area.
CCTV camera	Volume	13-Sep-2016 to 23-Sep-2019	Data collection expansion resulted from a thermal CCTV-based sensor feasibility study during a social experiment that was part of the Sathorn Model project. The software used for video signal processing of CCTV and thermal CCTV sensors is the same. The normal grade of CCTV (without thermal detection) has been selected to determine occupancy values but was disabled for cost-effectiveness during this scaled-up installation.
Loop Coil	Volume Occupancy	27-May-2016 to 13-Sep-2016	Data collection during the social experiment of the Sathorn Model project to validate the thermal CCTV-based sensors.
Thermal CCTV camera	Volume Occupancy	30-May-2016 to 24-June-2016	Data collection for the feasibility study of CCTV-based sensor type in real deployment conditions during the social experiment of Sathorn Model project.
Signal Control	Signal data	9-Nov-2014 to 14-Sep-2016	Data collection for short-term and long-run behaviors of how traffic police operate traffic signal light controls during rush hour periods or switch to automatic pre-timed traffic signal light settings during other periods.
Taxi	Speed	31-May-2016, 2-June-2016, 9-June-2016, 14-June-2016, 16-June-2016, 23-June-2016	Data collection to study before-and-after effects of the traffic flow management trial measures being implemented during the social experiment of the Sathorn Model project.
