6.6 Summary of Lesson 6


In this lesson, we explored how GIS tools can be used to help maintain an LRS and event data. We also examined dynamic segmentation, a process used to convert event data into event features, and some very useful diagrams known as Straight Line Diagrams (SLDs).

Our transportation organization of the week was AASHTO. We reviewed some of the important roles AASHTO plays in establishing policy, producing important guidance documents, conducting and promoting research, and in creating exceptional software products for a number of functional areas in transportation.

In our weekly webinar, we had the chance to interact with Bill Schuman, Sr. Vice President of Project Delivery for Transcend Spatial Solutions, and benefit from his expertise and many years of experience in the area of LRS.  We also had the opportunity to interact with Derald Dudley, a geographer and computer scientist with the USDOT's Bureau of Transportation Statistics (BTS).

In preparation for next week’s webinar, we also spent some time learning about intelligent transportation systems and, in particular, traveler information systems.
