The invention discloses a computational algorithm of a road condition information warning system. The computational algorithm includes the following steps that S1, drive route data related to a region are extracted from a GPS system; S2, in the road condition information warning system with a voice recognition system, road condition voice received by a receiver and broadcasted by the outside world is converted into road condition voice data through the voice recognition system, and regional information and road condition information which are included in the road condition voice data are registered in the road condition information warning system; S3, whether the drive route data include the regional information is judged, if yes, the fourth step is executed, and otherwise, the first step is executed; S4, whether the regional information includes road condition information of a jam or an accident is judged, if yes, the fifth step is executed, and otherwise the first step is executed; S5, a drive avoidance command is sent to the GPS system, and an alarm is given to a driver through an HMI. According to the computational algorithm, the driver can be informed of the conditions such as whether a drive route is jammed in time, the traffic jam phenomenon is reduced, and the traffic condition is improved.
