Abstract
Analyzing Bus Stop Ridership at the Chicago Transit Authority Track: Transportation Author(s): Scott Wainwright Transit agencies are becoming increasingly data rich from automatic passenger counter (APC) technology, however, methods for turning the data into functional information has lagged behind. The CTA has designed a database specifically for GIS that analyzes APC data in simple feature classes stored on SDE. APC and automated fare collection (AFC) data are combined to produce standardized, average weekday passenger boarding and alighting information for more than 12,000 bus stops. The entire agency accesses basic, stop-level ridership through an internal Web site. More than 40 GIS users, in departments such as route planning, facilities, scheduling, and operations, can easily analyze and display the information at many levels including stop, single-route, multiple-route, route-segment, corridor, zone, or system-wide. Data are produced each season also allowing for temporal analysis. Attendees will see how CTA incorporates ArcSDE 9.1, ModelBuilder, Personal Geodatabase, and ArcIMS to create and disseminate information based on the fast-growing technology of APC.
