2018 AASHTO GIS for Transportation Symposium
Monday, March 19 - Thursday, March 22, 2018, Little Rock, Arkansas



Workshop 1: The NPMRDS Data Integration

     Time: Monday 3/19 from 8 AM to 12 PM

     Presenters: Tianjia Tang (FHWA), Rich Taylor (FHWA), Wenjing Pu (FHWA), David Pace, and Vincent Fang

The National Performance Management Research Dataset (NPMRDS) provides detailed travel time data covering all the National Highway System roadways. To take full advantage of the NPMRDS travel time data, datasets such as the TMAS data (hourly volume data) and HPMS data are explored for integrating with the NPMRDS data both spatially and temporarily. The integrated dataset offers substantial additional information on both the intensity and extensity of travel. The integrated dataset enables total travel time estimation for a given segment of highways on an hourly basis. Because of this, bottleneck identification can be assessed from both a travel speed and total travel time standpoints. Also, the total travel time estimated enables a host of new transportation economics studies.


The workshop will discuss why the FHWA takes on the integration efforts, techniques developed and deployed, products developed, and next steps to be taken in the near future.

Workshop 2: GIS Capability Maturity Model Workshop

     Time: Monday 3/19 from 8 AM to 12 PM

     Presenters: Ian Kinder (ODOT), Allen Ibaugh (DTS), Mark Sarmiento (FHWA) 


Implementing and maintaining a GIS program is challenging, considering the wide range of factors to be identified, assessed and monitored.  Determining the best strategic program investment areas to improve the business value to the organization can be overwhelming.  One solution to these challenges include performing organizational maturity assessments, which provide a framework to identify a program’s strengths and weaknesses.


This workshop presents the on-going work of several DOT’s, FHWA, the Volpe Center, and industry consultants, to develop a DOT GIS organization capability maturity model.  Over the course of 2 peer exchanges, a workshop the 2017 GIS-T conference, and numerous conference calls, this group evaluated several existing maturity models, and crafted one specific to the needs of the DOT GIS community.  The goal is to provide a common framework DOT GIS leaders can leverage; to enable easy comparison of program’s across organizations all tasked with the same mission.


This workshop provides an overview of the DOT GIS CMM development, provides time for participants to test run the model, and then a general discussion session for participants to provide feedback of what works well or could be changed within the framework.  The goal of the workshop is to further refine the model, which will be presented to GIS-T participants later for potential adoption. 


Please bring a laptop if you want to participate in the hands-on portion of the workshop.

In this intensive, hands-on workshop, attendees will learn how to use StreetLight InSight®, an on-demand, cloud-based platform for transportation professionals to design and run customized mobility analytics derived from Big Data. StreetLight Data CEO Laura Schewel will lead an interactive training session that shows attendees how to use StreetLight InSight for four transportation use cases: a regional origin-destination study for travel demand modeling, a ramp-to-ramp study for measuring highway performance, a scanning study for analyzing transit accessibility, and an AADT analysis for the validation of rural traffic counts. In each example, Laura will cover the following topics: 

  • Choosing the right Big Data resource and types of Metrics for the question at hand.
  • How to interpret results from Big Data and techniques for comparing and integrating it with information from other sources
  • Visualizing Metrics in both StreetLight InSight and GIS tools, manipulating.CSV files in MS Excel and other statistical analysis software, and integrating Metrics into transportation modeling applications.
  • Quickly iterating and optimizing results by running several studies in StreetLight InSight.


Attendees will leave the session armed with practical tips and best practices for using the StreetLight InSight platform for their daily work.


Workshop 5: The Case for Open Source Software (OSS) for GIS-T

     Time: Monday 3/19 from 8 AM to 12 PM

     Presenters: Michael Terner (AppGeo) and Evan Wright (MS DOT)


Fundamentally, Open Source Software (OSS) is about collaboration -- and for GIS-T a collaborative team of the following companies is proposing to conduct this workshop, with State DOT participation:  AppGeo, Bentley Systems, Boundless, Carto, Cesium, and Gistic.  In the age of data science, the Internet of Things (IoT), virtual/augmented reality, and cloud computing, GIS “software as usual” approaches are due for an upgrade, and lower cost choices are emerging. This workshop will address the following sub-topics: (1) the OSS ecosystem - why it exists and how it operates to your benefit; (2) OSS technologies - what’s out there, including geoanalytics and geospatial IT platforms -- and licensing considerations and misconceptions; (3) how OSS can enhance existing enterprise GIS, LRS, and 3D visualization -- including how to blend OSS with your proprietary software investments, harmoniously; and, (4) the OSS adoption path - how to get started, how to build internal support and show results, quickly.  The workshop will include specific State DOT perspectives (i.e. Mississippi DOT), and will draw from the collaborative team’s direct and substantial experience with a variety of OSS technologies and platforms for geoanalytics and geospatial solutions, and will bring to GIS-T a wealth of industry perspective on this topic.
