Background (Show)

Lesson Learned

The Program will deploy, test, and operationalize cutting-edge mobile and roadside technologies and enable multiple CV applications, many of which were developed and prototyped by the USDOT Dynamic Mobility Application (DMA) program. The Open Source Application Data Portal (OSADP) is an open source repository of code for connected vehicle applications. Releases on the OSADP are freely available to all registered users. The computer code for each DMA prototype application, and input parameters and custom code for each DMA evaluation simulation, were submitted to the OSADP so that other CV researchers and deployers may take advantage of the developed code. The CV Pilot sites credit the OSADP for providing them with working prototypes of applications. The ability to download these applications meant that the sites did not need to develop the software entirely on their own, saving them both time and resources.

Allow for increased coordination with the Interdepartmental Radio Advisory Committee (IRAC) early on in the DSRC licensing process to help reduce what is traditionally a very lengthy process.

Connected Vehicle Pilot Deployment Program yields program management best practices for integrating and testing large disparate systems.

Connected vehicles should rely on more than one data feed to determine accurate location and speed

Consider installing additional vehicle detection equipment if it is determined that there is not sufficient market penetration for CV traffic signal control applications to work at their full potential

Facing a gap in standards interpretation, the Tampa and New York City Connected Vehicle Pilot Sites worked together to harmonize message structure for pedestrian safety applications.

For pedestrian safety warning applications, opt to collect pedestrian location data from LIDAR sensors instead of pedestrian mobile devices that often have insufficient accuracy.

Incentivize participation in CV deployments through benefits such as toll discounts

Include technical, operations, and legal personnel in stakeholder meetings to address the requirements of the CV deployment and ensure that participants' privacy is being maintained

Incorporate standardized over-the-air update procedures to permit efficient firmware updates for connected vehicle devices.

Obtain working prototypes of CV applications from the USDOT’s Open Source Application Data Portal (OSADP) to prevent time spent doing duplicative software development

Prevent the need for channel switching (a safety hazard) by designing CV communications to include dual radios in each vehicle

Publish all CV planning documentation to serve as an example for other early deployers to follow

The Tampa Connected Vehicle Pilot Program investigates damage to roadside units (RSUs) near lightning strikes and improves transient surge immunity by verifying nearby support structures are properly grounded.

The USDOT’s three Connected Vehicle Pilots successfully demonstrate cross-site over-the-air interoperability among six participating vendors.

Use local student mechanics where possible to perform CV equipment installations to provide students with required trainee experience and to contain costs

Use on-board connected vehicle (CV) technology and SPaT / MAP infrastructure messages to prevent wrong way entries on reversible express lanes.

When installing antennas on streetcars to support wireless connected vehicle applications, verify that radio performance is not compromised by interference from high-voltage power lines.
