Summary

This document outlines the Comprehensive Maintenance and Operations Plan (CMOP) for Phase 2 of the Wyoming Department of Transportation’s (WYDOT) Connected Vehicle (CV) Pilot Deployment Program. The pilot aims to enhance safety and mobility along the 402-mile Interstate 80 corridor by utilizing vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) communication technologies to mitigate the impacts of adverse weather on truck travel. The project is structured into three phases: planning, design and testing, and a real-world demonstration. This specific report details the operational and maintenance procedures required to support the system during the upcoming Phase 3 demonstration. The CV system is designed as a "System of Systems" comprising a Vehicle System and a Wyoming CV System. The Vehicle System involves equipping approximately 400 vehicles, including at least 150 heavy trucks, with on-board units (OBUs) capable of broadcasting Basic Safety Messages (BSM) and receiving alerts via Dedicated Short-Range Communications (DSRC) and satellite connectivity. These vehicles are categorized into WYDOT maintenance vehicles, highway patrol vehicles, integrated commercial trucks, and retrofit commercial vehicles. The Wyoming CV System consists of infrastructure and back-office components, including approximately 75 roadside units (RSUs), an Operational Data Environment (ODE), a Hardware Security Module (HSM), the Pikalert System for weather data fusion, a Data Broker, and a Data Warehouse. These components facilitate the generation and distribution of advisories regarding collision avoidance, speed management, work zones, and parking availability. The CMOP specifies the maintenance and operational protocols for in-vehicle devices, field devices, and Transportation Management Center (TMC) systems. It defines roles and responsibilities for maintenance and operations, detailing procedures for regular maintenance, software updates, diagnostic error handling, and system monitoring. The plan also covers configuration management, inventory control, and software licensing. Security and privacy measures are integrated through the use of a rented HSM for certificate management and adherence to specific security incident reporting policies. The system interfaces with external entities, including the National Weather Service and WYDOT’s 511 application, to provide comprehensive road condition information. The significance of this plan lies in its provision of a structured framework for the safe and efficient operation of the CV pilot during its demonstration phase. By establishing clear maintenance and operational guidelines, the document ensures the reliability of the communication infrastructure and the accuracy of the data used for traveler advisories. The pilot seeks to demonstrate how connected vehicle technology can improve decision-making for fleet managers and truck drivers, particularly during adverse weather conditions, while also enhancing WYDOT’s traffic management practices through better data utilization and variable speed limit activation.
