LaFlowbox (LaFlowbox.com) is a solution designed to understand movements from electromagnetic signals produced by connected devices such as mobile phones, audio equipment, vehicles etc. The solution includes sensors which detect electromagnetic waves and their characteristics, anonymous information is then sent to a central server where they are analyzed to produce statistics and datasheet on the transportation system. The data produced is used by public transport operators and policy makers to improve the transportation system. Laflowbox is an innovative solution developed by EXPLAIN (patent pending).
