8 GTIS DATA FLOW OVERVIEW Station One ISTHA Skyway Lake County WisDOT MnDOT IDOT D3, D5, D6 IDOT D4 IDOT D8 InDOT ITR ACTS IDOT D2 (Quad Cities) GTIS MDOT ODOT LCS MoDOT IDOT D1 (TSC) Real-time Private sector Mobile App Website Trip Alerts Map Reports XML 79 registered XML users 200GB of XML is transmitted per month

9 DATA FLOW FROM SOURCE Compliant Source Web Server Upload Events Database Processor Website Nonstandard Source Data Source Interface Non-events Replicator GTIS

10 DATA SOURCE INTERFACE Nonstandard Source File Download Schema Conversion Monitoring & Validation Processor Remote File Watcher Timer Data Source Interface

11 PROCESSOR Input data Validation Location resolution Fusion Data storage Output data

12 SCHEMA CONVERSION EXAMPLE Michigan DOT <lanes-affected> Gateway <lane> <category-id>

13 RECENT ADDITIONS TO GTIS Upgraded Enhanced trip report Real-time private sector probe data Arterial construction tracking system Big Data Storage of archived data ITS MIDWEST 2016 (GATEWAY EXPANSION)

14 UPGRADED TRAVEL TIME STATISTICS Recently Upgraded Weather integration Mobile responsive design Upgraded menus and graphics

15 ENHANCED TRIP REPORT (coming soon) Draw your trip versus Selecting from menus

16 TRIP REPORT ALERTS

17 TRIP REPORT EXAMPLE ALERT Web Site

18 REAL-TIME PRIVATE SECTOR TRAFFIC DATA Feed provided by HERE License covers Illinois ~3 MB per minute of compressed XML Drawn underneath public source data

19 MAPPING HERE DATA Wanted more than just congestion colors on a map layer image Difficulties with mapping the data in the RealTimeflow*.xml.gz files Expressways are mapped using flow lengths Arterials are mapped point to point HERE s Traffic Viewer web page is a useful resource

21 ARTERIAL CONSTRUCTION TRACKING SYSTEM Key Requirements: 100% web based system Support for existing paper forms Separate but integrated with GTIS Stake holders: IDOT District One construction, maintenance, permits, and operations personnel Time frame: Version 1 (construction projects) May 2015 to April 2016 Version 2 (maintenance and permit closures) April 2017 to January 2018

26 DMS ARCHIVE REPORT ITS MIDWEST 2016 (GATEWAY EXPANSION)

27 Open source Used by over 1,500 companies such as ebay and Netflix Fault tolerant Performant Decentralized Scalable

28 BIG DATA Archive contains 11 TB of XML files since 2004 Dynamic message sign text useful for monitoring incident response Uncompressing and parsing 288 DMSReport.xml.gz files too slow OLD NEW Source XML GTIS XML.gz Source XML XML.gz GTIS Admin website DMS Report NAS Admin website DMS Report NAS row Cassandra Cluster

29 PLANS FOR THE FUTURE Deploy upgraded maps Finish graphical trip creation Upgrade event severity algorithms Analyze accuracy of travel time data NPMRDS vs HERE vs VDS Deploy travel times created using private sector data Move more XML.gz files to Cassandra cluster
