Is travel simply a mandane daily chore? Or may it convery a higher meaning? Surveying aspects of one's life: dining, clothing, sheltering and travelling, all have an element of utility and an element of vanity. In contrast to its usual technical perception, we see transportation as a rich language to describe a personcharacterize a city and understand an institution.

Smart Device and Travel Time Use

Submitted by Jinhua Zhao on Fri, 03/22/2013 - 11:11pm

This research investigates the usage of smart devices and time at bus stops and on buses in Vancouver, Canada. Using passive observations and self-reported surveys mainly from college students, the majority of passengers were found to use their travel time actively. Most of the observed active activities are associated with the usage of smart devices. However, while the possession of smart devices is prevalent, less than one third of passengers used them during travel.

Unified estimator for excess journey time

Submitted by Jinhua Zhao on Fri, 03/15/2013 - 12:07am

Excess journey time (EJT), the difference between actual passenger journey times and journey times implied by the published timetable, strikes a useful balance between the passenger's and operator's perspectives of public transport service quality. Using smartcard data, this paper tried to characterize transit service quality with EJT under heterogeneous incidence behavior (arrival at boarding stations). A rigorous framework was established for analyzing EJT, in particular for reasoning about passenger’ journey time standards as implied by varying incidence behavior.
