Patent Images
1. A method for acquiring road condition information, comprising:
- forming an Ad Hoc network with other terminals by a terminal with a positioning system;
acquiring own position information through the positioning system;
communicating with other terminals in a network through the Ad Hoc network to exchange position information;
acquiring the road condition information according to the exchanged position information, comprising;
exchanging a terminal ID with the other terminals in the network through the Ad Hoc network;
setting a relative distance D2 to a designated terminal ID, andraising an alarm when detecting that a relative distance between a position of the designated terminal ID and the own position is greater than D2 according to the exchanged position information to prevent queue members from getting separated.
