- Purpose: Develop, operate, and maintain an open source portal that will
enable multiple stakeholders to collaborate on application development
|
|
13
|
- Open Source Portal supports:
- Configuration management of core assets
- Creation of new projects by stakeholders
- Submission of new applications and corresponding benchmark test data
sets, test procedures and documentation to a project
- Collaboration among stakeholders interested in inter-related projects
- Recognition of contributors of core assets
- Open Source Portal outcomes:
- Portal governance development and licensing agreement
- Well-documented and accessible core assets
- Deployment of secure portal infrastructure
- Promote collaboration and preserve intellectual capital
- Engage partners from academia and industry who may not be directly
involved in funded applications development and testing

- What do we mean by mobility?
- How do we measure it?
- How can connected vehicle and traveler data transform mobility
measurement as well as mobility?
- Performance Measure Application (to be posted to Open Source Portal)
- Source code and documentation on calculating travel time, delay and
reliability measures from a mix of fixed sensor and probe data
- Mode-independent approach identifies trip-level measures rather than
relying on aggregation of facility measures

- Cross-Cutting Need to Consider Mobile Devices
- Bundle development efforts have noted the need to explore the potential
value of BSM-capable mobile devices (DSRC, cellular and dual-mode),
e.g.,
- PED-SIG pedestrian safety/mobility application (M-ISIG)
- INC-ZONE temporary work zone for responders (R.E.S.C.U.M.E)
- Crowdsourcing traveler data for EnableATIS (itinerary data)
- Flexible transit service matching and ridesharing (IDTO)
- Devices may obtain or infer vehicle status data when carried into a
vehicle
(e.g., obtain external temperature by using a camera to read
dashboard display)
- Nomadic Platform Concept
- Explore the potential of mobile devices and supporting technologies to
meet critical application and data needs for both connected vehicles
and travelers
- Next step: Prototyping
- Further discussion during exercises:
- Need your feedback on most critical issues/opportunities with mobile
devices
- Breakout sessions will use the following assumptions

- Weather Data and Vehicle Itinerary Data:
- Provided as an element of an opt-in personalized traveler information
service
(business model includes aggregation and re-purposing of
non-PII (Personally Identifiable Information) derived from these
data)
- Possible weather data elements:
- Ambient air temperature, wiper status, traction control system
status
- Possible vehicle itinerary data elements:
- Origin, destination, departure time, desired arrival time, purpose
- Possible transit vehicle itinerary data elements:
- Schedule delay, occupancy, # of empty seats, # of empty bike rack
slots
- DSRC Range: 300 meters
