Controlled Probing - A system for targeted floating car data collection

Since vehicle to infrastructure communication will become state of the art in a few years, data from mobility and environment sensors in the vehicle could produce valuable information for traffic management and vehicle safety applications. The massive deployment of such data sources could however lead to high data traffic that would unnecessarily strain both the communication network, processing and storage resources. In this paper we present Controlled Probing, a system solution for floating car data collection which allows to select exactly the location, the time period and the type of sensor data to be collected. We address the system performance with respect to the accuracy and timeliness of the received probes.
