CASS COUNTY ROADWAY 18 EXTENSION STUDY – CASS COUNTY, ND 13 3.7 TRAFFIC SAFETY PERFORMANCE FOR 2013 TO 2017 The data and information used in the traffic safety section was provided by the Metro COG from a data set that was received from the NDDOT. The data included all traffic crashes in the Metro COG planning boundary for the years 2013 to 2017. The software program ArcGIS was used to select crashes for the study area based on a selection buffer of 250 feet from 52nd Street SE, as shown in Figure 8. The NDDOT and Department of Public Safety maintain criteria for what constituted a reportable traffic crash, and some very minor non-injury crashes may not be considered a reportable traffic crash. There was a total of six traffic crashes in the study area from 2013 to 2017. The crash locations and severity are included in Figure 8. Additional information for the crashes are included in the following Table 1 to Table 4. The corridor had one fatal crash, two injury crashes, and three property damage only crashes from 2013 to 2017 as shown in Table 1. The crash severity by year is shown in Table 2 and the only year with more than one crash was 2014. Typically, fatal and injury crashes occur when vehicles collide either head-to-head or at various angles to each other, of which the right-angle crash is typically the angle manner of collision with the highest potential of injury. Included in Table 3 are the crash severities by the manner of collision. The corridor experienced three angle crashes with two being right angle crashes; resulting in one a fatal crash and one property damage only crash. The study corridor is assumed to have a proportion of the traffic volumes that consists of vehicles travelling to or from the Kindred Public School system buildings in Kindred. Due to the potential of teen-age drivers travelling on the road, the driver ages of vehicles involved in crashes along the corridor were included in Table 4 to provide information on any patterns that emerged involving younger drivers or drivers of a certain age range. Please note that each driver in a crash is listed and more than one driver may be included in a crash. The 0 to 16 and 17 to 24 age ranges were grouped together so that all teen-age drivers along with younger drivers were included in one group for analysis. Based on the data in Table 4, three of the nine drivers involved in crashes were between 0 and 24 years of age which represents 33 percent of the total drivers. The 0 to 24 and 35 to 44 age ranges had three drivers involved in crashes which was the highest of all ranges. The fatal crash that occurred along the corridor was further examined to determine if any roadway or traffic control attributes may have been a contributing factor. Based on a review of the information available about the crash, a vehicle failed to yield at a yield sign to another vehicle on 52nd St. SE and a right-angle crash occurred between a passenger vehicle and a semi-truck. Based on the information available, it does not appear that any roadway or traffic control attributes contributed to the crash. Table 1. Crashes by Year ('13 to '17)
