Case Study

Pilot Project
on San Diego Roadways

Published September 22, 2020

Project background

In August 2020, the San Diego Regional Proving Grounds — a U.S. Department of Transportation designated regional test-bed for highly automated and self-driving vehicles — Caltrans, the San Diego San Diego Association of Governments (SANDAG) and other local agencies launched a pilot project to evaluate C-V2X technology as part of a connected roadside infrastructure, and to assess how it can support the widespread deployment of intelligent transport solutions.

The project covers a 3-mile stretch of highways and traffic light intersections off Interstate-805 and State Route 52 between Sorrento Valley and Kearny Mesa. It also includes vehicles equipped with onboard units (OBU) and roadside units (RSU).

During the pilot, infrastructure-to-vehicle (I2V) TIM messages are being sent out, covering reduced speed zone, work zone and disabled vehicle. With the expansion of the pilot, the implementation of SPaT is also planned.

Commsignia contribution

Commsignia contributed to the project by supplying
C-V2X enabled ITS-RS4 roadside units.

The ITS-RS4 platform can utilize all connectivity modes for real-time sensor data sharing as well as legacy backbone connectivity modes to the cloud.
The ITS-RS4 platform can utilize all connectivity modes for real-time sensor data sharing as well as legacy backbone connectivity modes to the cloud.

It features the latest cyber security measures including Hardware Security Modules (HSM) and V2X Software Stack to make sure that the system adheres and exceeds latest security standards.
The ITS-RS4 platform builds on the market leading and proven V2X Software stack supporting applications including

  • V2V for vehicle collision avoidance and safety systems;
  • V2I for enhanced traffic signal timing and priority;
  • V2N for real-time traffic routing and cloud services;
  • V2P for safety alerts to pedestrians, cyclists and motor bikes.

Outcome

The pilot is still ongoing, the experience gained will support transportation planning efforts of the region.
