Abstract:The objective of this pilot project was to demonstrate that the safety and reliability of the New York City Transit transportation system can be improved by automating the correlation and analysis of disparate track related data. Through the use of the supplied technology NYCT is able to use synthesize traditionally disparate data sets into focused and actionable information. Bentley’s Corridor Infrastructure Management (CIM) system was used to fuse multiple types of track related data into a single system and enabled the visualization of information with track charts and geographic maps. Furthermore, the CIM enables the identification of existing and anticipated problems along with indications of cause and effect relationships.
Through continuing usage of the pilot system, NYCT has concluded the capabilities of the pilot system enable NYCT to visualize the actual track network. This includes knowing the type of track (Type I, Type II, Type IIM, etc. (e.g., ballasted, guarded curve)) as well as the environmental conditions in the tunnel (Dry vs. Wet). Most importantly NYCT can see for the first time the combined data from multiple inspections by displaying the defects from these inspections on the map or track chart. Clusters and areas prone to certain types of wear are immediately apparent. Planning maintenance work with this type of tool promotes more efficiency.
A maintenance manager can sort the defects within a stretch of track, identify his work gang and material needs and schedule the work between point A and point B, with all this information on display and at their fingertips. In the past she or he would have to compile the information from the database by hand and mentally plan the job without the visual display. When doing the work by hand, a manager or supervisor would not look at more data then was minimally necessary. They would not see the whole line or even an extra mile or so down the track to take into account the bigger picture or a more effective solution. Multiply this with the fact that many work gangs receive assignments daily and the task of planning work effectively and efficiently suffers.
