Patent ID: 7741977

Claim:
A system for calculating vehicle travel times between at least two geographic locations, said system comprising: a first WLAN detection device located at a first geographical location, said first WLAN detection device receives a first WLAN signal from a WLAN device associated with a automobile when said automobile is proximate to said first geographical location, said first WLAN detection device comprises a first network protocol analyzer that creates a first packet comprising a MAC address from said first WLAN signal, a first signal received time stamp provided by said first WLAN detection device, and a first unique location identifier; a second WLAN detection device located at a second geographical location that is a predetermined distance from said first geographical location, said second WLAN detection device receives a second WLAN signal from said WLAN device when said automobile is proximate to said second geographical location, said second WLAN detection device comprises a second network protocol analyzer that creates a second packet comprising said MAC address from said second WLAN signal, a second signal received time stamp provided by said second WLAN detection device, and a second unique location identifier; a central server in electronic communication with said first WLAN detection device and said second WLAN detection device, said central server receives said first packet and said second packet, said central server further uses an algorithm to determine a travel time of said automobile between said first and said second geographical locations.
