The OSADP is a web-based portal that provides access to and supports the collaboration, development, and use of open-source transportation-related applications. Together, the U.S. Department of Transportation (USDOT) and OSADP facilitate the advancement of research, development, planning, testing, and deployment of connected vehicle and traveler-related applications and ITS. The OSADP features source code, software, applications, and resources (e.g., documentation, licenses, data) to support the use of or further development of these ITS-related applications. 
 
The following are new applications now available for download:
•    Pikalert Vehicle Data Translator (VDT) turns weather observations into road segment characterizations of weather and road conditions (i.e., "nowcasts" and forecasts). Data observations include vehicle-based measurements (i.e., vehicle actions, road conditions, and the surrounding environment) along with more traditional weather data sources. The VDT matches vehicle and weather data to the road segment based on position-latitude and longitude from global positioning system (GPS) data. 
•    Connected, Longitudinally Automated Lane Change Software supports lane-change maneuvers in which vehicles use automated speed control, vehicle-to-vehicle communications, and vehicle-based radar systems to facilitate a merge into a platoon of vehicles using cooperative adaptive cruise control. 
•    SmarTrAC is an Android smartphone application that compiles a summary of daily trips and modes used by the traveler. This application addresses the limitations of both the passive sensing and traditional travel survey tools. It allows use of the data by other applications that provide users with more information or services.
•    CloudThink Motion and Context Logger uses mobile phone motion-related sensors to collect and report GPS and acceleration values. The mobile phone motion-related sensors include the accelerometer, gyroscope, compass, and GPS, which allow CloudThink's logger to capture context data provided by the iPhone 5s' M7 motion coprocessor. The application transfers this data from the mobile device to a comma-separated text file for data analytics and motion studies.

Public agencies, service providers, researchers, application developers, and others are invited to visit the OSADP at http://itsforge.net to explore the use of these available applications and resources.
