Use multiple communications protocols (e.g. Cellular, Wifi, DSRC) to transfer data from mobile devices and optimize channel usage based on the use case when using Connected Vehicle systems to enhance weather observations.

Michigan DOT (MDOT) evaluated usage of environmental data in connected vehicle systems to support transportation agency management and operations.

Lesson Learned

  • Antennas installed on truck cabs are better than antennas installed on truck bed toppers.
  • Installers should use a consistent measurement process for collecting metadata for the locations where devices are installed on vehicles. Once installed, it is necessary to measure the locations of the sensors and tires in relation to the GPS antenna. It helps having two people doing those tasks to be more accurate.
  • Agencies should have a process for tracking shock degradation and compare to baseline for the vehicle.
Infrastructure Field Devices
  • Agencies and field personnel should ensure compatible interface and applications between RSUs and traffic signal controllers.
Mobile Devices
  • Use multiple communication protocols (e.g., Cellular, WiFi, DSRC) to transfer data from the mobile devices to back-office systems to optimize communication channels based on the type and volume of data required for each use case.
