An interesting task in highway management is to study potential impact of driver carpooling, based on an analysis of automatically collected automobile GPS position data. To identify potential enhancements to carpool participation, we set out to study places that have the highest numbers of trips with similar origin and destination locations. The source data for this experiment consists of nearly 40 million vehicle position records assembled from a single day of GPS-collected vehicle positions. The position data consists of longitude and latitude along with date, time, and speed. We used the Hadoop MapReduce framework for distributed parallel computation, considering its capability for analyzing larger data sets. Continue reading

The Esri development team would like to invite you to participate in a moderated and recorded usability study of a new application for GIS professionals currently under development.
Who we’re looking for…
- Existing ArcGIS for Desktop users
- ArcGIS Online and App users interested in professional GIS software
- Users of Esri Solutions (Local Government, Water Utilities, Land Records, 3D cities and campuses)
- Users with varying degrees of experience who author maps, analyze \ edit data, and manage GIS content
In total, we’re looking for 30 committed testers.
How it works…
Our sole intent and goal for this study is to assess the usability of our next generation professional desktop software; we want you to test our software, we’re not testing your computer, nor ArcGIS skills.
To consider you as a usability tester, we require that you are registered and approved by your employer to attend Esri User Conference and complete a pre-screening questionnaire—details below. Your time in the test lab is about 40 minutes.
Your test session will be recorded and observed by one or more members of the development team.
We thank you in advance for your time and look forward to meeting you in San Diego.
