From page 1...
... . Tools for analyzing running times and designing scheduled running times were created as an extension of the already existing software TriTAPT (Trip Time Analysis in Public Transport)
From page 2...
... Most analyses of AVL-APC data need time at specific locations, for example, to analyze running time or schedule adherence. While estimation of time-at-location is possible by interpolation from polling data, it has so far proven impractical.
From page 3...
... The greater the detail of the data stream, including the frequency of records, the more its potential uses for targeted investigations. One of the richest application areas for archived AVL data is in running time analysis, including designing scheduled running times and monitoring schedule adherence.
From page 4...
... APC data lends itself to a variety of passenger demand analyses including determining load profiles and using demand rates to set headways and departure times.While traditional analyses rely on mean values, APC data also offers the possibility of focusing on extreme values of crowding, as well as relatively rare events such as wheelchair lift and bicycle rack use. AVL data containing stop records can be used to verify and update base maps.
From page 5...
... One is an interactive tool for determining scheduled running times (allowed times) across the day, including selecting boundaries between periods of homogeneous running times.
From page 6...
... level. Where load does not necessarily become zero at the end of a trip, whether due to a route ending in a loop or to through-routing, data structures must account for passengers inherited from a previous trip, either by adding dummy stop records or using a field in a trip header record.
From page 7...
... While it may be programmed to deliver various types of reports, it also should offer the possibility of exporting tables as a result of its analysis, giving agencies the freedom to format as they wish. In addition, transit agencies should always maintain the freedom to manipulate and explore their archived data beyond the tools provided by any externally supplied software.
