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.

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
