F24-10-089 - Emergency Vehicle Preemption Pilot: Connected Vehicle Equipment

In the City of Greeley’s 2045 Transportation Master Plan (TMP), “Greeley on the Go”, the City captures its plans to update its existing transportation infrastructure to accommodate emerging technologies that promote resilience, safety, and mobility. As such, Greeley applied for and successfully received funding as part of the United States Department of Transportation (USDOT) Strengthening Mobility and Revolutionizing Transportation (SMART) Grant. The “Connected Greeley – Emergency Vehicle Preemption (CG-EVP) Pilot” is to evaluate and install connected vehicle (CV) technologies to provide emergency vehicle preemption (EVP) for emergency vehicles (e.g., firetrucks and ambulances), traffic signal priority for snowplows and maintenance vehicles, and detection and warning systems for Vulnerable Road Users (VRUs).
The pilot intends to use Advanced Transportation Controllers (ATCs) and Roadside Units (RSUs) to facilitate safe passage of emergency vehicles and snowplows through signalized intersections and to integrate VRU detection at select intersections with high pedestrian volumes. The legacy Opticom EVP system is intended to run in parallel throughout the duration of this pilot and is expected to remain fully operational. The CG-EVP Pilot will install RSUs at 43 intersections (see Exhibit 15); On-Board Units (OBUs) on 42 vehicles (see Exhibit 16), including snowplows, emergency vehicles (i.e., fire and ambulances), and maintenance vehicles; human machine interfaces (HMIs) on four maintenance vehicles; and VRU detection systems at three intersections in the pilot project study area shown in Figure 1 below.
