Bus Bunching Detection by Mining Sequences of Headway Deviations [chapter]

Luís Moreira-Matias, Carlos Ferreira, João Gama, João Mendes-Moreira, Jorge Freire de Sousa
2012 Lecture Notes in Computer Science  
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).  ...

Combining ITS and optimization in public transportation planning: state of the art and future research paths

Christina Iliopoulou, Konstantinos Kepaptsoglou
2019 European Transport Research Review  
The overview of literature collectively points to a series of common challenges faced by transportation professionals and underlines the need for better decision support tools for ITS data.  ...  Research on planning and operations of public transportation systems has not widely investigated the potential of combining optimization models with data originating from ITS.  ...  Real-time operations AVL have been widely applied for real-time control of public transportation systems and particularly for alleviating bus bunching, large waiting times at stops and so on [4] .  ...
