Wireless roadside inspection (WRI) Pilot Test

PBBTThe goal of the WRI Pilot Test was to determine the viability and effectiveness of wireless commercial motor vehicle inspections using currently-existing telematics technologies and systems.  The platform’s effectiveness and the commercial mobile radio services (CMRS) method’s ability to interface with the Government Back Office System (GBOS) were monitored and objectively evaluated.  This goal was to be met by demonstrating the transfer of a CMRS-generated safety data message (SDM) to the GBOS, demonstrating WRI CMRS end-to-end system functionality via two CMRS partner systems, and demonstrating carrier, enforcement, and compliance decision-making using associated WRI graphical User Interface (UI) populated with the CMRS-generated SDM information.

The Pilot Test was completed by defining the objectives and approach for the effort; establishing gratis partnerships with fleets, telematics providers, and safety sensor technology providers;  facilitating private partner system development and equipment integration;  conducting pilot testing in a real-world environment and staged data collection at fleet domiciles; performing a data analysis that explored the effectiveness of the implemented geofencing technology, validated the data contained in the SDM, and characterized the data collected; and drafting a final report that provided an overview of the CMRS pilot test activities and results.

During the Pilot Test, which extended from October 15, 2010 to January 31, 2011, two telematics teams were able to successfully submit SDMs to the WRI GBOS.  These SDMs included vehicle identification information, driver identification information, and driver status information.  A total of 1,705 messages were submitted during the period and were triggered at two inspection stations and at two domiciles.  A self-test feature was also implemented by one of the telematics teams.  The Pilot Test was successful in that many SDMs were transferred in real-time from vehicles moving at highway speeds and the primary goal and objectives of the effort were met.  The Pilot Test also revealed some critical issues relative to WRI and these issues point to the need for an intermediate step between the recently completed Pilot Test and the planned Field Operational Test.  These issues include the need for a GPS boundary solution that can support triggering in Consortiums that have radiused roadways, neighboring secondary roads and bi-directional traffic to ensure SDMs can be reliably triggered; the need for a pull-in/by-pass function to allow WRI to be used in near-real-time enforcement and interdiction; to overcome the limitations of the Pilot Test GBOS by methodically dissecting the current GBOS and developing a matrix of current functionality, maturity, scalability, and desired WRI production functionality; In addition, revisiting the viability and scalability of using XML as the only method of SDM data transfer to the GBOS should also be studied.
