(SEH)was retained to review the eight(8)signalized intersections within the City that currently do not have Emergency Vehicle Preemption (EVP),or the ability of emergency vehicles (police cars,fire trucks and ambulances)to obtain a green light sooner(to lessen travel times to incident sites). Our review focuses on equipment needed to make each EVP system operational,cost estimates for the City to obtain the necessary EVP equipment for each system, cost estimates (from Hennepin and Ramsey Counties, and the City of Minneapolis) for upgrading each signal system to accept EVP, and estimated construction costs outside of the materials costs. Our review also included a meeting with Jay Olson of the City Fire Department to discuss how to make each system operate to meet Police and Fire Department's needs. The following process was.used to analyze each intersection: We reviewed each intersection in detail to determine proper placement of detection devices. This included several drives through each intersection to account for curves, hills and other impediments to site distance to.an.intersection. . 0 We obtained the existing signal plans from the appropriate agencies (Hennepin and Ramsey Counties, and the City of Minneapolis) to determine other specific needs for each EVP system. This would include the need for additional cables and conduit to be installed,and use of inplace signal equipment to aid in the installation of the EVP system. • We contacted the supplier of EVP materials (detectors, cables and EVP equipment for the signal controller cabinets) that each County and the City of Minneapolis would require be used for each • intersection. Traffic Control Corporation is the local supplier of 3M Opticom EVP equipment, the brand of equipment that each agency only allows to be installed at each intersection. We discussed anticipated equipment needs with Traffic Control Corporation for each system, and obtained a cost estimate from them for the City to purchase these materials. By having the City purchase these Short Elliott Hendrickson Inc. Offices located throughout the Upper Midwest Equal Opportunity Employer We help you plan,design,and achieve.
