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.

OpenProj is an open-source desktop project management application similar to Microsoft Project.
OpenProj has a familiar user interface and even opens existing MS Project files.
OpenProj is interoperable with Project, Gantt Charts and PERT Charts.

Some Federal projects such as SHRP2 C10 have required that any software produced be under 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

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
