The presentation and usage of traditional graphs
is very important for effective and fast solution of routing in public
transportation. However, the traditional graph approach is unable to consider
the passenger requests such as total travel time, minimum number of transfer
and total distance of travel without pre-processing and/or post-processing.
Moreover, the vehicles are not represented on traditional graph. In this paper,
after analyzing the different kind of graphs, we propose a novel graph named as
public transportation graph. The proposed graph models the public
transportation system and considers distance, waiting time, travel time,
self-transportation and number of transfers simultaneously for efficient trip
planning. In this way, passenger requests can be met without pre-processing and
post-processing. In addition, the vehicles are also considered and demonstrated
in the proposed graph.

Toplu taşıma çizgesi: Etkin seyahat planlaması için toplu taşıma ağının çizge teorisi tabanlı bir modeli

Öz

Geleneksel çizgelerin
sunumu ve kullanımı, toplu taşımada etkin ve hızlı bir yönlendirme çözümü için
oldukça önemlidir. Ancak, geleneksel çizge yaklaşımı, ön ve/veya son işlem
olmaksızın yolcuların toplam seyahat süresi, asgari transfer sayısı, toplam
seyahat mesafesi gibi isteklerini dikkate alamamaktadır. Dahası, geleneksel
çizgelerde araçlar temsil edilememektedir. Bu çalışmada, farklı çizge türleri
incelendikten sonra, toplu taşıma çizgesi olarak isimlendirilen yeni bir çizge
önerilmiştir. Önerilen çizge etkin bir seyahat planlaması için toplu taşıma
sistemini modellemekte ve mesafe, bekleme süresi, seyahat süresi, kendi kendine
ulaşım ile transfer sayısını aynı anda göz önünde bulundurabilmektedir. Bu
sayede ön ve son işlem olmaksızın yolcu istekleri karşılanabilmektedir. Ayrıca,
önerilen çizgede araçlar da göz önünde bulundurulmuş ve gösterilmiştir.
