CUTR LCTR FDOT RAPTS Resource for Advanced Public Transportation Systems (RAPTS) APTS Data Archiving and Mining System (ADAMS) http://technology.rapts.org http://www.rapts.org Data Mining and Analysis Tasks • Literature search and review • Determine APTS technologies and candidate Florida transit properties • Develop the APTS Data Archiving and Mining System (ADAMS) • Acquisition of hardware and software tools required to conduct analysis FDOT/CUTR/LCTR Data Mining and Analysis Task Overall Goal Research and analyze the use of various APTS technology data outputs for prototypical information systems that enhance the management and performance of public transportation services. FDOT/CUTR/LCTR Previous Work Sponsored by FDOT • Visited Tri-Met and AMTRAK • Collected APC Data from JTA • Developed a Virtual Test Bed • Created GIS Web Maps • Developed Customized Reports • Started Exploring Data Mining FDOT/CUTR/LCTR http://technology.rapts.org Technology Web Site to Deploy Adams FDOT/CUTR/LCTR Research Area FDOT/CUTR/LCTR Data Mining Flow Chart AVL Data Automatic Vehicle Location System Users APC Data Automatic Passenger Counters Farebox Data Electronic Fare Collection System Data Transformation and Internet SQL Server Quality Assurance Users ADAMS BSI Data Bus Stop Inventory Users GIS Data Geographic Information System FDOT/CUTR/LCTR Business Intelligence Be more efficient Data Analysis to help make decisions Data extract, clean, and transformation BI: Put questions first, then get the answers from the dataset. FDOT/CUTR/LCTR Data Process • Decision Data •Data Clean and Transformation •Analysis •Data Mining •Reports Raw Data FDOT/CUTR/LCTR Sample • Raw Data: FDOT/CUTR/LCTR Sample • Analysis: FDOT/CUTR/LCTR Sample • Analysis: FDOT/CUTR/LCTR Sample • Mining: FDOT/CUTR/LCTR Sample • Report: FDOT/CUTR/LCTR Data Mining Algorithms • Microsoft Association Rules • Microsoft Neural Network • Microsoft Naive Bayes • Microsoft Decision Trees • Microsoft Time Series • Microsoft Clustering • Microsoft Sequence Clustering FDOT/CUTR/LCTR Microsoft Naive Bayes Bayes’ Rule states that if you have a hypothesis H and evidence about that hypothesis E, then you can calculate the probability of H using the following formula: FDOT/CUTR/LCTR Microsoft Decision Trees Entropy (p1, p2,...,pn) = -p1log2p1 –p2log2p2... -pnlog2pn Where p1, p2,...,Pn are the probability of each state on the predictable attribute, p1+ p2...+Pn= 1. FDOT/CUTR/LCTR Microsoft Time Series Xt=f Xt 1,Xt 2,Xt 3,Xt n+εt _- - - -i where xt is the time series under investigation, and n is the order of auto regression, which is generally much less than the length of the series. The last term, epsilon, represents the noise.
