What is the Open Source? Tour with Open Source Software - Examples DynusT (Dynamic Urban Systems in Transportation) Closing Presentation Outline

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.

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

Macro-Meso-Micro Integration Analyze Ingress/Egress points for weaving MesoMicroMacro Estimate toll lane usage and revenue Proposed toll lanes  Macro  Travel Demand Models (TDM)  Micro  e.g. VISSIM Source:

Mesoscopic Traffic Simulation? Source:

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
