Abstract:
The present invention provides a method for judging a highway abnormal event, which can determine the traffic jam phenomenon in the target road segment based on the trajectory data of each sample vehicle of the target road segment. The solution of the present invention has the following beneficial effects of 1. comprehensively considering the vehicle speed information of the sample vehicles to judge the traffic jam event; 2. determining the overall traffic jam event of the target road segment; 3. more accurately judging the traffic jam event of the target road segment.

Claim (Index 4):
The method according to  claim 3 , wherein the step of constructing the two-dimensional matrix U representing the discretized trajectories of the sample vehicles based on the divided road segments and time periods in the step 2 further includes:\n finding starting points H a  and ending points H b  of the trajectories S=[(t 1 ,l 1 ),(t 2 ,l 2 ), . . . , (t n ,l n )] of the sample vehicles, wherein l 1 \u2208H a , l 2 \u2208H b , and the H is expressed as H ab ={H a ,H a+1 , . . . , H b }; finding starting time points T c  and ending time points T d  respectively corresponding to the trajectories t 1  and t n  of the sample vehicles, wherein T c\u22121 <t 1 \u2264T d ,T c \u2264t 2 <T d+1 , and the time points included in the trajectories of the sample vehicles are expressed as T cd ={T c , T c+1 , . . . , T d }; finding location information corresponding to the time points T i  in the trajectories of the sample vehicles, wherein t k <T i <t k+1 , wherein the trajectory points corresponding to the t k  and t k+1  are P(t k ,l k ), (t k+1 ,l k+1 ); obtaining the road segment H i  corresponding to the T i  based on the l k  and the l k+1 ; and constructing the two-dimensional matrix U representing the discretized trajectories of the sample vehicles based on the T i  and H i , wherein the discretized trajectories are expressed as S\u2032=[(H 1 ,T 1 ),(H 2 ,T 2 ),(H 2 ,T 3 ),(H 3 ,T 4 ),(H 5 ,T 5 ), . . . ].
