Anoka County intersection (Source: Anoka County) <br />The data illustrated a fairly significant positive trend within the County as all crash type <br />categories and focus areas have seen a measurable decrease in the number of crashes <br />between 2006 and 2015. <br />High Frequency Intersection Crash Locations <br />The Anoka County Highway Department uses the Minnesota Crash Mapping Analysis <br />Tool (MnCMAT) to review high crash locations to identify patterns that are correctable <br />and locations on the County system that would benefit from traffic control or geometric <br />improvements. Crash data is used to identify projects for the federal Hazard Safety <br />Improvement Program (HSIP), Local Road Improvement Program (LRIP), Central Safety <br />Fund, Safe Routes to School (SRTS), and other funding programs, as appropriate. <br />Intersection crashes were sorted utilizing an intersection buffer to aggregate crashes at <br />each intersection. An approximate 250-foot radius surrounding each intersection was used <br />for the majority of intersection. On some of the more access controlled corridors, such as <br />Trunk Highway 47 and Trunk Highway 65, a 500-foot radius surrounding each intersection <br />was used. On intersections that are closely spaced, within 500 feet of each other, the <br />distance between intersections was divided evenly. <br />Figure 23 depicts the highest crash locations in Anoka County; this figure is zoomed in as <br />all of the high crash locations are located in the southern portion of the County. Table 22 <br />shows all intersections that had 35 or more crashes during the five-year analysis period; a <br />total of 49 intersections. <br />Crash frequency only includes the total number of crashes observed at each intersection <br />location, this is not always indicative of a serious problem. Intersection crash rates can be <br />a better indicator of problem <br />intersections as the rate <br />normalizes the crashes based <br />on the vehicle exposure at <br />the intersection. However, <br />intersection crash rates <br />were not evaluated for each <br />site as part of this crash <br />evaluation. Therefore, there <br />may be some intersection <br />locations with higher crash <br />rates that are not included in <br />this intersection list of crash <br />frequency; specifically in the <br />more rural areas with low <br />volume intersections. <br />ANOKA COUNTY 2040 TRANSPORTATION PLAN UPDATE I CHAPTER 3- EXISTING CONDITIONS <br />62 <br />
