Bus Bunching Detection by Mining Sequences of Headway Deviations
[chapter]
2012
Lecture Notes in Computer Science
Preserved Fulltext
In highly populated urban zones, it is common to notice headway deviations (HD) between pairs of buses. ...
In this paper, we propose to find BBS (Bunching Black Spots)sequences of bus stops where systematic HD events cause the formation of BB. ...
We would also like to thank the support of the project Knowledge Discovery from Ubiquitous Data Streams (PTDC /EIA-EIA/098355/2008). ...
