GIS for Transportation: Principles, Data and Applications

4.6 Summary of Lesson 4


In this lesson, we learned about transportation networks. Specifically, we examined the elements which comprise a network and the activities that go into creating one. You then had the opportunity to solidify this knowledge by modeling a transportation network in ArcGIS through the construction of a network dataset from roadway centerlines and other associated data.

Our transportation organization of the week was the FHWA. You learned a little about the history and key roles of the FHWA. We also took a look at NHS, a network of roadways deemed critical to the nation and FHWA’s geospatial data initiative known as the GDC.

In our weekly webinar, we had the opportunity to interact with Mr. Greg Ulp, a senior project manager who was the technical architect for MPMS-IQ, a GIS application used by PennDOT to disseminate project information to the public and other interested parties.

In preparation for next week’s webinar, we learned how transportation planning and the NEPA review processes which seek to assess and mitigate environmental impacts related to transportation projects have become more tightly integrated and about the role GIS has played in helping to bring the two together.

Finally, you had the opportunity to get to know one of your classmates a little better and share some of your ideas and questions about this week’s lesson materials.
