Transportation Impact Analysis <br /> Providence Regional Medical Center New Medical Clinic Building and Parking Lot Reconfiguration April 2016 <br /> Traffic Safety <br /> A review of historical collisions was completed to identify potential safety issues for vehicles, <br /> pedestrians, and cyclists. The review is based on the Washington State Department of <br /> Transportation (WSDOT) collision records, which include both State and City roadways. The <br /> period between January 1, 2013 and December 31, 2015 was reviewed, which represents <br /> the most recent complete three-year period of collision history for the study area. <br /> Potential safety issues at the study intersections were identified following the procedures in <br /> Chapter 4 of the Highway Safety Manual(AASHTO, 2010). An analysis of crash rates for the <br /> study intersections was completed to identify the average crash frequency based on the <br /> number of vehicles traveling through the study intersections. The typical measure for <br /> determining crash rates at intersections is the number of crashes per million entering vehicles <br /> (MEV). Intersections where the observed crash rate is greater than critical crash rate would <br /> be reviewed further for potential safety issues. Table 2 provides a summary of collision <br /> history at the study intersections and the crash rate analysis. <br /> Table 2.Collision Analysis Summary <br /> Number of Collisions' Observed Greater <br /> Observed Critical Crash than Critical? <br /> Location 2013 2014 2015 Total Crash Rate' Rate3 <br /> 1.

Crashes per Million Entering Vehicles(MEV). <br /> 3. Calculated according to Equation 4-11 in the Highway Safety Manual,2010. <br /> As shown in Table 2, observed crash rates at the study intersections are less than the critical <br /> crash rates so no safety issues are identified. No fatalities or bicycle collisions were identified <br /> in the study area for the past 3-years. There were 4 pedestrian-related collisions in the study <br /> area along Broadway with 2 at 13th Street and 2 at 19th Street. These pedestrian-related <br /> collisions resulted in injury and were due to vehicles failing to yield to the pedestrians or <br /> inattention while driving. Both the Broadway intersections are signalized with marked <br /> crosswalks. <br /> Non-Motorized Facilities <br /> Sidewalks are provided along both sides of 13th Street and the neighborhood streets in the <br /> vicinity of the site. These streets provide connections to the bus stops located along Colby <br /> Avenue and Broadway. Marked pedestrian crosswalks and/or ADA curb ramps are provided <br /> at intersections within the vicinity of the project site including signalized pedestrian crossings <br /> at the study intersections along Broadway. <br /> Bicycle lanes are provided along both Colby Avenue and 19th Street within the study area. <br /> Along other streets in the site vicinity cyclist would share the roadway with motor vehicles. <br /> Transit Service <br /> Transit service in the study area is provided by Everett Transit and Community Transit. The <br /> nearest bus stops to the clinic are located along Colby Avenue at 13th Street with access to 2 <br /> transit routes. Additional bus stops near the site are along Broadway at 12th and 13th Streets <br /> 10 <br />
