  7. Gardner Transportation Systems innovative leader in the development and integration of advanced transportation management systems. Company Siemens Gardner Transportation Systems • General Information History Location My team Products My Work icons Development CCTV control Freeway Management System Future projects

  8. History • 1994: Craig Gardner founded Gardner Transportation Systems • 2001-06-01: Siemens acquired Gardner Transportation Systems • Now: a wholly subsidiary of Siemens Energy & Automation • keeps its management policy • Siemens provides financing and a new CEO • Nearly 70 employees are currently working in The company

  9. Location Concord, California Corporate Headquaters (16 people) Salt Lake City, Utah (16 people)) Los Angeles, California (5 people) Atlanta, Georgia (8 people) Tucson, Arizona Houston, Texas Palm City, Florida

  10. GEORGIA Office • Located in Duluth, GA • Created in 1998

  11. My team 8 people: Walt Townsend, regional manager, Mike Clance, senior Software engineer, Pete Montigny, customer support, and Christel Henry, Zuyi Shen, Nagendra Tripathi, Jeff Chadwell, Maxime de Baynast: software developers.

  12. Products • NextPhase: intersection management software • Icons:Advanced Transportation Management System • base package: - traffic signals control - closed circuit television control (CCTV) - dynamic message signs control (DMS) • Optional add-on modules: ramp metering, highway advisory radio, etc..

  13. My Work • I developed and debugged parts of the iconscontroller database editor, included into the icons graphical user interface (IGUI). • I created a SNMP agent for AustinCCTV. • I am also working on the FMS bridge component of the Freeway Management System. Company Siemens Gardner Transportation Systems My Work icons Development CCTV control Freeway Management System Future projects

  14. Dynamic icons Icons Graphical User Interface Base map

  15. Database editor Upload Load Icons Database Download Store Icons Database Editor • The icons database editor functionalities:

  16. Icons Database Editor Close controller Preview controller data Print controller data Restore values Create controller Download data base to controller Store controller from database Upload data base to controller Compare fields and database Load controller from database

  17. Software Change Request (SCR) Each time something needs to be developed or debugged, an SCR is created.

  18. Example of SCR One dll is loaded for each controller type. When creating a new controller, the Pull down list was static whereas it should be dynamic.

  19. CCTV control What is a CCTV system? The Traffic Operation Center have the ability to: - locate and confirm the existence of the incident, - zoom in to get a better look, - proceed to get the traffic moving again as safely and efficiently as possible through the use of ramp meters, …

  23. SNMP Agent Purpose:The goal of the SNMP Agent is to simulate SNMP communications with an ATM Switch to see how CCTV control is managing the ATM network. Why simulating ATM switches? ATM Switches are: - Big and heavy - do not belong to GTS Not always available

  24. SNMP Agent development A typical agent usually: • Implements full SNMP protocol • Stores and retrieves management data as defined by the Management Information Base • Sends an asynchronously signal an event to the manager I developed the SNMP Agent thanks to:SNMP++v3.0 library from HPAGENT++v3.4 library from Agent++

  25. SNMP Agent development The SNMP agent is defined thanks to the ATM switch MIB. What is a MIB? MIB stands for Management Information Base A MIB is a collection of managed objects residing in a virtual information store.

  26. Initialize connection (port, …) Instanciation of the MIB C++ objects Listen NO Is there any request? YES Request processing Result: SNMP Agent behavior The Agent processes the following SNMP requests: - Get (retrieve operation) - GetNext (traversal operation) - Get Response (indicative operation) - Set (alter operation) - Trap (asynchronous trap operation)

  27. Difficulties Surprisingly, the main difficulty was while compiling the MIB files, SNMP++ and Agent++ libraries. · Difficulties when compiling MIB files: - MIB files came from the Marconi company. - some objects in the “fore-switch.mib” file were not properly defined. · Difficulties when compiling SNMP++ and AGENT++ libraries: SNMP++ and AGENT++ libraries were written in C++.these libraries were designed to be used with the UNIX Operating System

  28. Freeway Management System The Freeway Management System (FMS) controls the traffic when incident occurs on highways and help to reduce nonrecurring congestion. Timeline of an incident

  29.

  33. Conclusion • This internship is technically very interesting, concrete and close to the skills that I was taught at ESIAL (Object Oriented Programming, SNMP…) • Traffic control systems and especially intelligent transport systems are very useful, even necessary. • Working abroad represents obviously a great opportunity for diverse experience and education. More specifically to Siemens Gardner Systems: • advantages of a small company • advantages of a big company I have thoroughly enjoyed my internship period up to date. I have tried my best to have a sound relationship between ESIAL and Siemens GTS Company.
