Presentation Transcript

  1. How Open Source Helps Your Projects? • Majed Al-Ghandour, Ph.D., PE, CPM • Program Development Branch • NCDOT • NCAMPO 2012 Conference • Asheville, NC • May 2 - 4, 2012

  2. Presentation Outline • What is the Open Source • Tour with Open Source Software • DynusT • (Dynamic Urban Systems in Transportation) • WordPress • Closing

  3. Open Source Licenses • My understanding is that “open source” licenses such as GNU GPL3 don’t necessarily require that the software be “free” in terms of not charging for it.  • They just require that • (a) the source code always be distributed with the executable, and • (b) that anyone who receives the software cannot make it proprietary.    • Check your legal team to provide an open source license.

  32. Strategic Highway Research Program Some Federal projects such as SHRP2 C10 have required that any software produced be under an open source license. SHRP2 C10 Source: http://www.shrp2c10.org/SHRPC10Portal/Home.aspx

  33. DynusT(Dynamic Urban Systems in Transportation) • Regional Operational Planning Capability • Regional - area larger than corridor • Operational - traffic flow dynamics sensitive to signals, road configurations • Planning - short-term impact and long-term equilibrium • Simulation • Mesoscopic Traffic Simulation • Dynamic Traffic Assignment (DTA) • Micro-meso-micro integration

  40. What is Dynamic Traffic Assignment? • A method to predict/estimate how trip-makers may shift to other routes or departure time in response to: • Congestion • Pricing • Controls • Incidents • Improvements • Understand how individual travel decisions impact an entire region, by • Time of day • Origin-Destination (OD) zones • Transportation modes

  41. Macro Meso Micro Proposed toll lanes Analyze Ingress/Egress points for weaving Estimate toll lane usage and revenue Macro-Meso-Micro Integration • Macro • Travel Demand Models (TDM) • Micro • e.g. VISSIM Source: http://dynust.net/wikibin/doku.php?id=start:new_page2

  42. Mesoscopic Traffic Simulation? Source: http://dynust.net/wikibin/doku.php?id=start:new_page2

  43. Other Freeway Operations Scenarios/Strategies • Dynamic message signs • Congestion warning • Mandatory detour • Speed advisory • Information strategies • Pre-trip information • In-vehicle information • Incident • Work zone • Managed lanes • Truck only • Truck restriction

Top right shows queues due to the work zone Bottom left shows a view of work zone area allowing to show how vehicles diverse around network work zone area. Bottom right shows speed profiles of the links
